管廊隧道由于其结构复杂，包括隧道、桥梁、地下空间等，信号传输易受到干扰和衰减，因此需要无线对讲系统具备广泛的信号覆盖能力，确保管廊隧道内各个区域都能实现无缝通信，在管廊隧道中，特别是在弯道、交叉口、长距离直线段等区域，容易出现信号盲区。无线对讲系统需要采用适当的技术手段来消除这些盲区，确保通信的连续性
Due to its complex structure, including tunnels, bridges, underground spaces, etc., signal transmission is susceptible to interference and attenuation, so the wireless intercom system is required to have a wide range of signal coverage capabilities to ensure that seamless communication can be achieved in each area of the pipe gallery tunnel, and in the pipe gallery tunnel, especially in areas such as curves, intersections, and long-distance straight sections, signal blind spots are prone to occur. The wireless intercom system needs to adopt appropriate technical means to eliminate these blind spots and ensure the continuity of communication.
管廊隧道将市政、电力、通讯、燃气、给排水等各种管线集于一体，通过科学合理的布局，将不同种类的管线分层或分区设置，以避免相互干扰和安全隐患，同时密闭性较高
The pipe gallery tunnel integrates various pipelines such as municipal, electricity, communications, gas, water supply and drainage, and sets up different kinds of pipelines in layers or partitions through scientific and reasonable layout, so as to avoid mutual interference and potential safety hazards, and has high airtightness
管廊隧道是一个相对封闭的空间，且内部结构复杂，存在弯道、分支等，这些因素都可能对有线通信造成阻碍
The pipe gallery tunnel is a relatively closed space, and the internal structure is complex, with curves, branches, etc., which may hinder wired communication
许多管廊隧道具有较长的距离和较大的跨度，如长江苏通GIL综合管廊总长度达5468.5米，这种长距离通信需求难以通过有线方式有效满足。
Many pipe corridor tunnels have long distances and large spans, such as the total length of the GIL comprehensive pipe corridor in Changjiangtong is 5468.5 meters, and this long-distance communication demand is difficult to effectively meet by wire.
