With the continuous development of network communication technology, the domestic network has covered the homes of ordinary people, but the indoor coverage system of the network cable network needs to be further improved. The optical fiber distribution system is a signal coverage system integrating GSM, TD-SCDMA, and other standards. It is mainly composed of system access unit, system expansion unit, and system remote unit. Wireless network is an important communication technology, which is easy to use and can be connected wirelessly over long distances. The purpose of this paper is to study an optical fiber distribution system for indoor coverage design of wireless networks, so as to achieve faster and more efficient coverage. In this paper, a wireless network signal processing algorithm is proposed, and a systematic method for designing the wireless network indoor coverage of the optical fiber distribution system is proposed, and the algorithms are compared and tested. The test results in this paper show that the signal strength obtained by the algorithm in this paper is -54.83 dB, while the traditional artificial design algorithm is only -45.97 dB. In addition, the wireless network base point of the algorithm in this paper is also 3 lower than the traditional one. Moreover, the coverage rate achieved by the algorithm in this paper is 3.17% higher than that of the network cable network base point layout given by the genetic algorithm, and the average received signal strength is 3.34 dB higher. In addition, the algorithm in this paper takes 9.1 s, 11.2 s, and 5.3 s for the three scenarios of underground parking lot, large shopping mall, and residential residential area, while the traditional manual design algorithm takes 87.9 s, 108.8 s, and 51.7 s, respectively. The algorithm in this paper is only about 1/10 of the traditional artificial design algorithm. Therefore, it can be concluded that the coverage effect of the wireless network indoor coverage system of the optical fiber distribution system designed in this paper is significantly improved.
随着网络通信技术的不断发展，国内网络已覆盖普通百姓家庭，但有线网络的室内覆盖系统仍需进一步完善。光纤分布系统是一种集成了GSM、TD-SCDMA等标准的信号覆盖系统。它主要由系统接入单元、系统扩展单元和系统远端单元组成。无线网络是一项重要的通信技术，使用方便，可实现远距离无线连接。本文旨在研究一种用于无线网络室内覆盖设计的光纤分布系统，以实现更快、更高效的覆盖。本文提出了一种无线网络信号处理算法，给出了一种设计光纤分布系统无线网络室内覆盖的系统方法，并对算法进行了比较和测试。本文的测试结果表明，本文算法获得的信号强度为-54.83dB，而传统人工设计算法仅为-45.97dB。此外，本文算法的无线网络基点也比传统算法低3个。而且，本文算法实现的覆盖率比遗传算法给出的有线网络基点布局高3.17%，平均接收信号强度高3.34dB。另外，本文算法在地下停车场、大型商场和住宅小区三种场景下分别耗时9.1s、11.2s和5.3s，而传统人工设计算法分别耗时87.9s、108.8s和51.7s。本文算法仅为传统人工设计算法的约1/10。因此，可以得出结论，本文设计的光纤分布系统无线网络室内覆盖系统的覆盖效果有显著提升。
