Deep analysis of microwave towers and communication towers: functions, characteristics, and applications

Introduction

In today's era of surging information, the iteration of communication technology is constantly changing, profoundly reshaping our lives and the world. From 1G in the past to 5G today, and even the exploration of 6G, every leap in communication technology is like stirring up waves in the long river of human civilization, driving society forward with great strides. Behind this grand communication network, microwave towers and communication towers stand silently like two loyal guardians, shouldering the heavy responsibility of information transmission. They are similar in form, but each has its own unique features and applications. Have you ever been curious about the differences between them? Now let's unveil the mysterious veil of microwave towers and communication towers together, and explore their unique mysteries in the world of communication.

一、Basic concepts of microwave tower and communication tower

（一）Microwave tower

    Microwave tower, as a key infrastructure for microwave communication, is a towering structure specifically designed for microwave signal transmission and emission. It usually stands on higher ground, such as mountaintops, rooftops, or open plains, to ensure that microwave signals can be transmitted over long distances with minimal obstruction. Its prominent feature is the installation of a parabolic antenna at the top, which is like a huge "eye" that accurately focuses and emits microwave signals, transmitting information in the form of radio waves to distant receiving stations.

    The structural design of a microwave tower is closely related to its functional requirements. In order to support parabolic antennas and withstand various natural environmental challenges, microwave towers generally use sturdy steel structures. The tower body is constructed from materials such as angle steel or steel pipes, which have been carefully selected and processed to have excellent strength and stability. The components are connected by bolts, which not only facilitates installation and maintenance, but also ensures the structural integrity of the entire tower. In addition, the microwave tower is equipped with a series of ancillary facilities, such as lightning protection towers, lightning rods, platforms, ladders, antenna brackets, feeder racks, and lightning protection down conductors. The lightning protection system can effectively introduce lightning into the ground, protecting the tower and equipment from lightning damage; Platforms and ladders facilitate technicians to install, debug, and maintain antennas and equipment; The antenna bracket is used to firmly support the parabolic antenna, ensuring that it can maintain a stable working state under various adverse weather conditions; The feeder rack is responsible for transmitting microwave signals from the transmitting equipment to the antenna, ensuring the quality of signal transmission.

（二）Communications tower

    The communication tower is an indispensable component of modern communication networks. It is like a bridge of information, connecting different communication devices and enabling various information to be freely transmitted over a vast area. The main function of a communication tower is to provide stable support for communication antennas, ensuring that the antennas can work at the appropriate height and position, thereby achieving effective signal coverage. Whether it's high-rise buildings in the city or vast land in remote mountainous areas, communication towers silently stand there, safeguarding people's communication needs.

    The structural forms of communication towers are diverse, including angle steel towers, three tube towers, single tube towers, and guy towers. The angle steel tower is assembled from angle steel, which has the advantages of relatively simple processing, transportation, and installation, high overall stiffness, strong bearing capacity, and mature technical application. However, angle steel towers also have some shortcomings, such as bulky appearance, large footprint, and may not be suitable for areas with high aesthetic requirements. The tower body of the three tube tower is made of steel pipes, with three main steel pipes as the skeleton, supplemented by horizontal and diagonal steel for fixation. This structure makes the cross-section of the tower body of the three tube tower triangular, which is slimmer, simpler in structure, has fewer parts, is easier to construct, and occupies a smaller area compared to angle steel towers. Therefore, the cost is relatively low. But the strength of the three tube tower is relatively weak, and its appearance is not aesthetically pleasing. A single tube tower is vertically erected from a thick steel pipe, with a simple and beautiful shape, small footprint, fast construction speed, and convenient relocation and reuse. However, the cost of single tube towers is relatively high, and installation requirements are high, requiring the use of cranes for installation. Moreover, the components are large, and the handling costs are also high. Due to the large number of welds in the production process, quality control is difficult. A cable tower is a relatively special structure that cannot stand independently and requires surrounding cables to secure it, like a giant pulled by ropes. The advantages of cable towers are cheap price, light weight, and easy installation, but their disadvantages are also very obvious, such as large cable footprint, poor reliability, weak bearing capacity, difficult installation and maintenance of cables, multiple components, nodes, and difficulties in relocation and reuse. Therefore, cable towers are mainly used in open mountainous areas, rural areas, and other areas with relatively low communication requirements and relatively open terrain.

二、Comparison of functional characteristics

（一）Functional characteristics of microwave tower

1. Signal transmission characteristics: The microwave frequency band used by microwave towers is usually between 300MHz and 300GHz, which has unique transmission characteristics. Microwave transmission is like the straight propagation of light in space. Unlike low-frequency signals, it is not easily affected by diffraction from obstacles such as terrain and buildings. However, this also means that its transmission path needs to be relatively open and unobstructed. Its advantages are significant. Firstly, the microwave band has a wide frequency band, up to 29700MHz, which is like a wide information highway that can accommodate massive amounts of data information, achieve high-speed data transmission, and meet high bandwidth requirements for applications such as high-definition video transmission and fast exchange of large-scale data files. Secondly, microwave signals have extremely strong directionality, and antennas can accurately focus microwave signals in specific directions, just like the strong beam of light emitted by a flashlight, with highly concentrated energy. Therefore, microwave transmitters only need to output a few watts of power to stably transmit signals to tens of kilometers away, effectively reducing energy loss during signal transmission and improving transmission efficiency. In addition, microwave signals are less affected by external interference such as industry, electricity, and space during propagation, just like sailing in a peaceful ocean of information. The communication quality is stable and reliable, which can ensure the accurate transmission of information and reduce signal distortion or loss caused by interference.

2. Antenna and coverage: The parabolic antenna at the top of the microwave tower is a key component for signal transmission. This type of antenna works based on the principle of reflection, and its shape design is exquisite. When microwave signals reach the reflective surface of a parabolic antenna, no matter where the signal comes from, they will concentrate and converge at the focal point of the parabola under the reflection effect. This feature enables parabolic antennas to achieve extremely high gain in specific directions and angles, thereby enabling long-distance signal transmission. Generally speaking, the coverage range of microwave towers is relatively wide. Under ideal terrain conditions, the signal coverage radius of a single microwave tower can reach tens or even hundreds of kilometers. However, its coverage area is subject to various factors such as terrain, antenna height, transmission power, and surrounding environment. For example, in areas with complex terrain such as mountainous regions, microwave signals may be blocked by mountain peaks, resulting in signal propagation obstruction and reduced coverage; In cities, towering buildings may also obstruct and reflect microwave signals, affecting the quality and coverage of signal transmission.

（二）Functional characteristics of communication tower

1. Multi network support: As the cornerstone of modern communication networks, communication towers can fully support multiple types of communication networks. Whether it is the long-standing 2G and 3G networks, the widely popular 4G network, the 5G network leading the future communication trend, or even broadcasting and television networks, wireless local area networks (WLAN), etc., communication towers can perfectly adapt to them, providing a stable support platform for signal transmission and reception of different networks. In the 4G network environment, communication towers help achieve high-speed mobile data transmission, allowing users to smoothly watch videos, make video calls, and quickly download various files; In the era of 5G networks, communication towers shoulder the responsibility of ushering in a new era of ultra-high speed, low latency, and large capacity communication, providing stable and reliable communication support for many emerging application scenarios such as smart factories, autonomous driving, and remote healthcare. Taking 5G network as an example, communication towers closely cooperate with 5G base station equipment to widely cover high-frequency 5G signals in the streets and alleys of cities, as well as the vast fields of rural areas, enabling users to enjoy unprecedented communication experiences brought by 5G anytime and anywhere. For broadcasting and television networks, communication towers stably transmit television signals to thousands of households, allowing people to watch a variety of colorful television programs and obtain various information.

2. Signal coverage flexibility: Communication towers have excellent flexibility in signal coverage. Its antenna types are diverse, covering various forms such as omnidirectional antennas and directional antennas, and can be flexibly adjusted according to actual needs, such as height, elevation angle, azimuth angle, etc. In the central area of the city, due to the numerous high-rise buildings and dense population, communication needs present diverse and complex characteristics. At this point, the communication tower can achieve 360 degree signal coverage by using omnidirectional antennas, ensuring that users in all directions around can receive stable signals. At the same time, based on the distribution of surrounding buildings and the actual coverage effect of the signal, the height and elevation angle of the antenna can be flexibly adjusted to better penetrate the buildings, reduce signal blind spots, and improve signal quality. For example, in some high-rise residential areas, optimizing the antenna parameters of communication towers can effectively solve problems such as weak signals in high-rise buildings and poor signals in lower floors, providing users with high-quality communication services. In some specific scenarios, such as industrial parks, sports venues, etc., communication needs are often concentrated in a specific direction or area. In this case, the communication tower can use directional antennas to accurately focus the signal on the target area, improve the coverage strength and transmission efficiency of the signal, and avoid signal waste and interference.

三、Differences in application scenarios

（一）Application scenarios of microwave towers

1. Long distance communication link: Microwave towers play a crucial role in long-distance communication and are a key link in building backbone communication networks. It can cross geographical barriers such as mountains, rivers, deserts, etc., and achieve high-speed signal transmission between different regions. For example, in the construction of communication networks in China, microwave towers are widely used for inter provincial and intercity communication connections. In some remote areas, laying optical cables is costly or difficult to construct, and microwave towers have become the preferred solution for achieving communication coverage. The construction of microwave towers in areas such as the Qinghai Tibet Plateau enables these regions to maintain smooth communication with the outside world, providing a solid guarantee for local economic development, social stability, and cultural exchange. In addition, in the field of international communication, microwave towers are also commonly used to connect communication networks between different countries, promoting global information interconnectivity.

2. Special terrain communication: In special terrain environments such as mountainous areas and water bodies, the communication advantages of microwave towers are becoming increasingly prominent. Due to the linearity and directionality of its signal transmission, microwave towers can effectively overcome the obstruction and interference of terrain undulations on signals. In mountainous areas, microwave towers can be installed on mountaintops or high places to transmit signals along valleys or ridges, ensuring that all villages and residential areas in the mountainous area can receive stable communication signals. For example, in some nature reserves or tourist attractions in deep mountain forests, microwave towers provide reliable communication services for forest rangers, tourists, and local residents, ensuring that they can contact the outside world in a timely manner in emergency situations. In the vicinity of water bodies, such as coastal areas, large lakes, or banks of rivers, microwave towers can transmit signals across the water surface, avoiding the complexity and high cost of laying optical cables underwater. For ships operating at sea, residents on islands, and industries such as coastal fishing and shipping, the presence of microwave towers enables them to obtain real-time meteorological information, maritime rescue information, and convenient communication with land.

（二）通信塔的应用场景

1. Urban communication network: In cities, communication towers are the core infrastructure that ensures smooth communication. With the rapid development of cities, high population density, numerous buildings, and explosive growth in communication demand. The dense distribution of communication towers can ensure good signal coverage in all areas of the city. In urban commercial areas, residential communities, industrial parks, and other places, communication towers carry a large number of communication services such as voice calls, text messages, and data transmission. For example, in bustling commercial pedestrian streets, people can use their mobile phones anytime and anywhere for shopping, payment, social media sharing, map navigation, and other operations, all of which rely on the support of mobile towers. At the same time, the communication tower also provides communication support for intelligent transportation systems, intelligent security systems, intelligent municipal facilities, etc. in the city, promoting the intelligent development of the city. By collaborating with 5G base stations and other devices, communication towers can meet the needs of urban residents for high-speed and low latency communication, providing a stable network environment for emerging applications such as high-definition video live streaming, virtual reality (VR)/augmented reality (AR) experiences, and autonomous driving.

2. Indoor and outdoor signal coverage: Communication towers are not only responsible for outdoor signal coverage, but also play a key role in supplementing indoor signals. In large buildings such as office buildings, shopping malls, hotels, hospitals, airports, etc., outdoor signals often experience severe attenuation due to obstacles such as walls and floors, resulting in poor indoor signal quality. At this point, the communication tower combines with the indoor distribution system to introduce signals indoors, and transmits signals through antennas distributed in various corners of the building, achieving all-round signal coverage indoors. For example, in large shopping malls, consumers can enjoy smooth communication services whether in shopping areas, dining areas, or underground parking lots, thanks to the collaborative work of communication towers and indoor distribution systems within the mall. In some high-rise residential buildings, communication towers optimize the direction and power of antennas, combined with indoor distribution systems, to solve problems such as weak signals in high-rise buildings and poor signals in lower floors, ensuring the communication quality of residents indoors. In addition, in some special places such as underground tunnels, elevator shafts, etc., communication towers can also provide stable communication signals for these areas through specialized signal coverage solutions, ensuring people's communication needs in special environments.

四、Different considerations in design and construction

（一）Key points for the design and construction of microwave towers

1. Structural strength and stability: The structural strength and stability of microwave towers are key elements in their design and construction. Due to the need for microwave towers to carry heavy parabolic antennas and other ancillary equipment, as well as withstand various natural environmental factors such as wind loads, seismic forces, etc., extremely high requirements are placed on their structural strength. In the design process, engineers will use professional structural mechanics analysis methods to accurately calculate the material specifications and dimensions required for each part of the tower body based on various factors such as tower height, antenna weight, local meteorological conditions (such as maximum wind speed, earthquake intensity, etc.), and geological conditions. For example, for microwave towers built in strong wind areas, the thickness and strength grade of tower steel will be appropriately increased, or the structural form of the tower body will be optimized, such as adopting more reasonable truss structure or adding slant support members, to effectively improve the wind resistance of the tower body. To enhance the stability of microwave towers, deep buried foundations are usually used to firmly embed the tower base into the ground at a certain depth, ensuring a stable connection between the tower body and the foundation, which can withstand significant external forces. In some areas with complex geological conditions, special treatment of the foundation may also be required, such as pile driving reinforcement, using expanded foundations, etc., to meet the strict requirements of microwave towers for foundation stability. In addition, during the installation process of the tower body, construction personnel will strictly control every link to ensure that the connections of each component are tight and reliable, meeting the design accuracy requirements, so that the entire microwave tower can maintain stable and reliable operation in various harsh environments after completion, providing a solid guarantee for the stable transmission of microwave signals.

2. Electromagnetic compatibility: Electromagnetic compatibility is an important aspect that cannot be ignored in the design of microwave towers. Due to the high requirements for signal accuracy and stability in microwave communication, it is necessary to ensure that the microwave tower is not affected by external electromagnetic interference during operation, and that it does not cause electromagnetic interference to other surrounding electronic devices. In order to achieve good electromagnetic compatibility, the layout of the antenna is carefully planned when designing a microwave tower. By arranging the position and orientation of antennas reasonably, sufficient isolation can be maintained between different antennas to reduce electromagnetic coupling between them. For example, for transmitting and receiving antennas, techniques such as spatial isolation or polarization isolation are used to ensure that the transmitted signal does not interfere with the received signal. In the structural design of the tower, a series of shielding measures will also be taken. For example, using a metal tower structure and ensuring its good conductivity and continuity forms an effective electromagnetic shielding cavity to block the intrusion of external electromagnetic waves. At the same time, for transmission lines such as cables and feeders inside the tower, cables with good shielding performance will be selected, and reasonable wiring methods will be adopted, such as avoiding line crossings and staying away from strong interference sources, to reduce electromagnetic signal leakage and coupling. In addition, grounding measures also play a key role in the electromagnetic compatibility design of microwave towers. By setting up a comprehensive grounding system at the tower base, the static charges accumulated on the tower body and the electromagnetic interference currents that may be induced are quickly introduced into the ground, ensuring that the tower body is always in a stable potential state and further reducing the impact of electromagnetic interference. Generally, circular or radial grounding electrodes are used to ensure that the grounding resistance meets the relevant standard requirements, so that the grounding system can effectively function.

（二）Key points for the design and construction of communication towers

1. Height and location selection: The height and location selection of communication towers are directly related to their signal coverage effect and communication quality, and are key factors that need to be considered in the design and construction process of communication towers. When determining the height of a communication tower, engineers will consider multiple factors comprehensively. Firstly, it is necessary to analyze based on the coverage requirements of the communication network and the characteristics of the surrounding terrain and landforms. If the target coverage area is a relatively flat and open area, such as suburban or rural plain areas, increasing the height of communication towers appropriately can effectively expand the coverage radius of signals and improve the transmission distance of signals. For example, in some vast rural areas, in order to achieve signal coverage for the entire village and surrounding farmland, the height of communication towers may be designed to be over 30 meters. However, in urban central areas, due to the high density and complex distribution of buildings, excessively high communication towers may cause excessive reflection and interference of signals at close range, which in turn affects signal quality. Therefore, in cities, the height of communication towers is usually adjusted based on the average height of surrounding buildings, generally slightly higher than the surrounding buildings, to ensure that signals can effectively cover the streets and interior of buildings. For example, in some high-rise commercial areas of cities, the height of communication towers may be between 20-30 meters. Meanwhile, the location selection of communication towers is also crucial. It is necessary to consider the obstacle situation of signal propagation and try to avoid the influence of large buildings, mountains and other obstructions as much as possible. For example, when building communication towers in mountainous areas, it is usually chosen to be located on relatively open and high terrain such as mountaintops or ridges to ensure that signals can be smoothly transmitted to various villages in the valley. In cities, communication towers are prioritized for layout in open areas such as parks and squares, or installed on the roofs of buildings to fully utilize spatial resources, reduce the occupation of urban land, and achieve better signal coverage. In addition, with the continuous development of communication technology, such as the construction of 5G networks, precise planning and optimization of communication tower locations have become more important. Advanced signal propagation models and geographic information system (GIS) technology are needed to repeatedly simulate and analyze the location of communication towers, in order to meet the requirements of 5G networks for high-speed, low latency, and large capacity signal transmission, and provide users with better communication services.

2. Integration of aesthetics and environment: In today's society, people's demand for environmental aesthetics is increasing, and communication towers, as a common infrastructure, are receiving more and more attention in their exterior design. The aesthetic and environmental integration of communication towers can not only enhance the overall image of cities or regions, but also reduce the visual impact on surrounding residents and increase public acceptance of communication facilities. In terms of exterior design of communication towers, designers will fully consider the characteristics and styles of the surrounding environment, adopt diverse design techniques, and make the communication tower complement the surrounding environment. In areas with beautiful environments such as urban parks or scenic spots, communication towers may adopt biomimetic or landscape design. For example, designing a communication tower into a tree, flower, or other shape with natural elements, integrating it with the natural landscape of the park and creating a unique scenic line. In some historical and cultural cities or ancient building protection areas, the design of communication towers will draw on the style and elements of local traditional architecture, such as using antique architectural shapes, color matching, etc., so that the communication tower can not only meet the communication function, but also coordinate with the surrounding historical and cultural atmosphere, inherit and promote local cultural characteristics. In urban commercial areas or modern building areas, the design of communication towers tends to lean towards a simple and stylish style, using modern building materials and language, such as streamlined design and the use of glass curtain walls, which complement the surrounding high-rise buildings and modern facilities, showcasing the modern atmosphere and sense of technology of the city. In addition, in order to further reduce the visual impact of communication towers on the environment, greening or decorative treatment will be carried out on the tower body. For example, planting vines on the tower body to gradually cover it during its growth process, forming a green "tower coat"; Alternatively, some artistic lighting installations can be installed on the tower to create a unique visual effect at night through the changes and flickering of lights. This not only beautifies the communication tower, but also adds a charm to the urban night scene.

五、The difference between maintenance and management

（一）Maintenance and Management of Microwave Towers

1. Antenna and equipment maintenance: The parabolic antenna and microwave equipment of a microwave tower are the core components for their normal operation, and their maintenance is crucial. Regularly inspect the parabolic antenna to see if there are any debris accumulation, deformation, or damage on the surface of the antenna. For example, after severe weather such as strong wind, rainstorm or sandstorm, the antenna surface may be attached with foreign matters such as dust, branches, sand and stones, which will affect the signal reception and transmission performance of the antenna and need to be cleaned in time. At the same time, check whether the feed source of the antenna is normal. The feed source is a key component for transmitting microwave signals to the antenna, and its performance directly affects the quality of signal transmission. For microwave equipment such as microwave transceivers, modems, etc., regular performance testing and calibration should be conducted. Check whether the various technical indicators of the testing equipment meet the requirements, such as transmission power, reception sensitivity, frequency stability, etc. Regularly calibrate and debug the equipment according to its user manual and technical specifications to ensure that it operates in optimal condition. In addition, it is necessary to check the heat dissipation of the equipment to ensure that it operates within the normal temperature range. Microwave equipment generates heat during operation, and poor heat dissipation may lead to equipment failure or performance degradation. Regularly clean the cooling fans, radiators, and other components of the equipment to ensure good ventilation.

2. Environmental monitoring and protection: The environment in which the microwave tower is located has a profound impact on its operational stability, so it is necessary to closely monitor the surrounding environment and take effective protective measures. In terms of environmental monitoring, we should focus on weather changes, especially severe weather such as thunder and lightning, rainstorm, gale and snowstorm. Install meteorological monitoring equipment to monitor real-time meteorological parameters such as wind speed, direction, rainfall, and lightning activity. When encountering strong wind weather, timely evaluate the impact of wind on the microwave tower. If the wind speed exceeds the design bearing limit of the tower, it may cause the tower to shake, deform or even collapse. Reinforcement measures or adjusting the orientation of the antenna should be taken in advance to reduce wind resistance. For thunderstorm weather, it is necessary to ensure that the lightning protection system of the microwave tower is intact and effective. By monitoring parameters such as grounding resistance, it is determined whether the lightning protection system is working properly. In terms of protective measures, corresponding response strategies should be developed for different severe weather conditions. In terms of lightning protection, in addition to ensuring the normal operation of the lightning protection system, lightning arresters can also be installed on the power lines of microwave equipment to prevent damage to the equipment caused by lightning induced voltage. In rainstorm and snowstorm weather, the inspection of tower foundation shall be strengthened to prevent the tower foundation from being soaked and eroded by accumulated water or snow, which may lead to instability of the tower foundation. For microwave towers in mountainous areas, it is also necessary to prevent geological disasters such as landslides and mudslides from impacting the tower body. Set up protective fences or retaining walls around the tower to reduce the damage of geological disasters to the microwave tower.

（二）Maintenance and management of communication towers

1. Antenna system and line maintenance: The antenna system and feeder of the communication tower are key links to ensure the quality of signal transmission, and their maintenance work needs to be highly valued. Regularly inspect the antenna system, including the appearance of the antenna, installation firmness, accuracy of azimuth and elevation angles, etc. Check the surface of the antenna for corrosion, deformation, looseness, etc. If there are any problems, repair or replace them in a timely manner. The azimuth and elevation angles of the antenna should be adjusted regularly according to the optimization requirements of the communication network and changes in the surrounding environment to ensure optimal signal coverage. For example, in cities, with the construction or demolition of buildings, the propagation environment of signals will change. At this time, it is necessary to adjust the angle of the antenna accordingly to ensure that the signal can effectively cover the target area. At the same time, attention should be paid to the maintenance of the feeder line. The feeder line is a transmission line that connects the antenna and communication equipment, and its performance directly affects the quality of signal transmission. Regularly check whether the connectors of the feeder are loose, whether the sealing is good, and whether the feeder is damaged or aged. For any problems discovered, promptly tighten, seal or replace them. In the installation process of the feeder, it is necessary to follow the construction standards of the specifications, ensure that the bending radius of the feeder meets the requirements, and avoid damage to the signal lines inside the feeder due to excessive bending, which affects signal transmission. In addition, it is necessary to regularly test the performance of the feeder, such as testing the loss and standing wave ratio of the feeder, to ensure that it is within the normal range.

2. Safety inspection and hazard elimination: The safety inspection of communication towers is an important measure to ensure their stable operation and personnel safety, and it is necessary to establish a sound inspection system and process. The safety inspection includes multiple aspects such as tower structure, foundation, ancillary facilities, electrical system, etc. In the inspection of tower structure, the focus is on checking whether the tower body is deformed, cracked, corroded, and whether the connecting bolts of the tower are loose or missing. For tower foundations, it is necessary to check for settlement, tilt, and other issues by regularly using measuring instruments such as level gauges and theodolites for monitoring. Check whether the ancillary facilities of the communication tower, such as ladders, platforms, railings, etc., are firm and reliable, and whether there are any damaged or missing components. For electrical systems, check whether lighting equipment, navigation lights, lightning protection devices, etc. are working properly, and whether there are safety hazards such as short circuits, open circuits, and leakage in electrical circuits. The safety inspection cycle should be determined based on factors such as the importance, service life, and surrounding environment of the communication tower. Generally speaking, for important communication towers or communication towers in harsh environments, the inspection cycle should be shortened and the inspection frequency should be increased. For example, communication towers in coastal areas or areas with frequent strong winds can undergo a comprehensive inspection once a month; In general, communication towers can undergo a comprehensive inspection every quarter. After each natural disaster such as gale, rainstorm and earthquake, special inspection shall be carried out in time to eliminate potential safety hazards caused by natural disasters. For safety hazards discovered during inspections, they should be promptly eliminated. For minor hidden dangers, such as loose bolts, minor damage to components, etc., they can be repaired or replaced on site; For more serious hidden dangers, such as significant deformation of the tower body and severe settlement of the foundation, a detailed repair plan needs to be developed and professional personnel organized for repair. During the repair process, necessary safety measures should be taken, such as setting warning signs and building temporary supports, to ensure the safe progress of the repair work. At the same time, it is necessary to strengthen the safety training of communication tower maintenance personnel, improve their safety awareness and operational skills, and ensure their personal safety in maintenance work.

六、Future development trends and interrelationships

（一）The impact of technological evolution on both

With the rapid development of technology, the evolution of 5G and future communication technologies will have a profound impact on microwave towers and communication towers. In the 5G era, the expansion of communication frequency bands to high frequency bands and the increase in base station density have put forward higher requirements for the carrying capacity, height planning, and spatial layout of communication towers. To meet the transmission characteristics of 5G signals, communication towers need to be further optimized in design, such as using new materials to reduce weight, enhance structural strength, and more accurately plan their position and height to avoid signal interference and achieve efficient coverage. In terms of microwave towers, the high bandwidth and low latency requirements of 5G have prompted the continuous upgrading of microwave communication technology. The transmission capacity and efficiency of microwave towers will continue to improve to adapt to the rapid transmission of massive data. In addition, the exploration of future technologies such as 6G will drive communication frequency bands towards higher frequency bands such as terahertz, which may trigger innovative changes in the structural design and antenna technology of microwave towers and communication towers, such as developing antennas that are compatible with higher frequency bands, optimizing the electromagnetic shielding performance of tower bodies, etc., to cope with the challenges and opportunities brought by new technologies.

（二）The prospect of collaborative cooperation

Microwave towers and communication towers do not exist in isolation in communication networks, but have significant complementarity. In the future construction of communication networks, the two will collaborate to jointly build intelligent and efficient communication networks. In densely populated areas such as cities, communication towers undertake extensive signal coverage tasks to meet the daily communication needs of a large number of users; Microwave towers can serve as an important means of data transmission, quickly transmitting data from various communication base stations to the core network, reducing the pressure of fiber optic deployment, and improving network deployment flexibility. In remote areas or special terrain environments, microwave towers can establish backbone communication links with their long-distance transmission advantages, providing data transmission support for the construction of subsequent communication towers and gradually improving regional communication network coverage. Looking forward to the future, with the rise of emerging application scenarios such as the Internet of Things and industrial Internet, microwave towers and communication towers will be further integrated to form an integrated communication infrastructure solution. They will jointly provide stable and high-speed communication support for fields such as intelligent transportation, intelligent energy, and intelligent security, helping to build an intelligent society with interconnected everything and promoting digital transformation and innovative development in various industries.
