地铁无线覆盖网络构架和关键技术研究

Study on the Architecture and Key Techniques of Subway Wireless Network Coverage

针对地铁无线网络覆盖中共建共享通信系统多、系统间干扰损耗大、覆盖场景多样性、小区间切换频繁等难点,提出含基站、电源、传输3个模块的地铁无线覆盖网络构架,同时对各种场景下无线网络覆盖策略、小区划分和切换策略,以及POI和泄漏电缆的应用等关键技术进行了深入的研究。将研究成果应用到某运营商地铁线路的网络建设中,达到了良好的覆盖效果。该研究为后期地铁无线网络设计提供了思路和建议。

For the difficulties existing in subway wireless network coverage, such as many sharing communication systems, high inter-system interference loss, diversity of covering scenario and frequently switching between cel s, a network architecture of sub-way wireless network including base stations, power supply and transmission was proposed, and further study on the key techniques was performed, such as the strategy of covering various scenarios, the cel division, the cel switching, the application of POI and leakage cable. The application of the research results to the construction of subway route of a subway operator demonstrated that our proposed system achieves good coverage effect and it wil provide feasible ideas and suggestions for the design of the later subway wireless network.
