【摘要】 在我国许多大中城市中,由于新建小区很多、高楼密集拥挤、利用室外基站的覆盖在发展中遇到了很多困难,而在小区内无法设置基站或基站的覆盖面积有限,就需要小区整体覆盖。新建小区的深度覆盖已成为业界关注的重点和难点问题,目前尚没有一套完整的、很好的解决方案。本文对PHS小区覆盖技术进行深入研究,就小区覆盖需要解决和注意的关键技术问题进行分析、探讨,创造性地提出针对新建小区PHS系统深度覆盖的完整解决方案,提出了小区深度覆盖中存在的重点和难点问题的解决方法。本文通过对关键技术研究,首次全面、系统地提出了PHS小区覆盖的相关理论和解决办法,通过典型案例实践检验和常见问题分析将理论与实践相结合。提出的小区深度覆盖解决方案具有可操作性,很好地解决了新建小区的深度覆盖问题,大大提升了PHS网络的通信质量和覆盖水平,提高了PHS业务的综合竞争力,具备良好的经济效益和社会效益。PHS在技术体制上不属于蜂窝移动通信体制,难以过渡到蜂窝移动通信。PHS是一项在现阶段经济实用的可选接入技术,是过渡型的网络技术,是固定电话的延伸和补充。将长时间与现有蜂窝移动通信系统及未来3G并存,为用户提供差异化服务。更多还原

【Abstract】 In most fast-growing cities in China, more and more tall buildings in new communities in such a high density have caused many difficulties on deploying radio coverage by utilizing outdoor BTS sources. Furthermore, the fact that BTS equipment can not be deployed inside the communities or limited coverage area makes it necessary to have a total solution for community coverage. Depth coverage of the new district has become the industry’s focus and difficult problems, is still not a complete, very good solution.In this paper, the PHS technology area covered in-depth study on the area coverage and attention to the need to resolve key technical issues for analysis, study, creatively put forward new area for PHS system depth coverage of the complete solution to the depth of coverage in the area of focus And difficulties in the solution to the problem.Based on the research of key technologies, the first comprehensive, systematic way to the PHS area covered by the relevant theories and solutions through the typical case of the test of practice and the common will of the problem of combining theory with practice. The depth of coverage area is workable solution, a good solution to the new district covers the depth of the problem, greatly enhance the communication of the PHS network quality and coverage levels, improve the business PHS’s comprehensive competitiveness, with good economic returns And social benefits.PHS technology in the system does not belong to cellular mobile communication system, difficult transition to cellular mobile communications. PHS is an economical and practical at this stage of the optional access technology, is a transitional type of network technology, is an extension of fixed telephone and added. Will be a long time with the existing cellular mobile communication system and the future coexistence of 3 G, to provide users with differentiated services.更多还原
