【摘 要】隨著通信運營網絡規模的不斷擴大,城市室外的覆蓋已基本達到無縫連接,且話音質量已得到改善與提高,但室內覆蓋率相對較低,語音質量較差,如何全面統籌通信運營商的網絡覆蓋需求,充分掌握室內外網絡現狀,推動覆蓋方案由單一、孤立地宏站、室分規劃向宏微結合、室內外協同規劃轉變,提供技術合理、成本最優的一體化綜合解決方案,成為工程設計與建設工作的一項重要內容。本文就通信工程室內場景一體化綜合覆蓋方案設計方法進行分析與研究。

【Abstract】With the continuous expansion of communication operation network, outdoor outdoor coverage has basically reached a seamless connection, and the voice quality has been improved and improved, but indoor coverage is relatively low, the voice quality is poor, how to comprehensively co-ordinate communication Operators need to fully cover the indoor and outdoor network status, promote the coverage plan from a single, isolated macro station, room division planning to macro and micro integration, indoor and outdoor collaborative planning changes, providing reasonable and cost-effective integration of integrated Solutions, engineering design and construction has become an important part of the work. This article analyzes and researches the design method of integrated indoor coverage integrated scenario of communication engineering.

1 研究背景
通信系統設計的過程中,應因地制宜采用宏微結合、室內外協同的綜合覆蓋解決方案,保證通信網絡覆蓋質量、降低綜合成本,進一步提升通信工程設計方案的能力,并細分覆蓋場景,綜合覆蓋目標環境特點、建設難度、投資風險、維護便利、商務定價等因素,實現覆蓋方案的精細化設計。
對于室內覆蓋技術方案來講,采用室內覆蓋方式主要有室外覆蓋室內和室內深度覆蓋兩種,常用的技術手段有室外宏站、無源分布系統、光纖分布系統、室外微站、室內微站等。在進行室內規劃設計時,應結合覆蓋場景特點,選擇合理的技術手段或多種技術手段相結合,實現覆蓋方案的最優化[1]。
2 室內一體化綜合覆蓋室外宏站解決方案
宏站覆蓋是通過室外宏蜂窩基站用以解決室內的覆蓋問題,宏蜂窩基站的特點是功率較高,覆蓋范圍較大,可以滿足小型樓宇、小型建筑群的深度覆蓋以及大型樓宇、大型建筑群的淺層覆蓋需求?!?br>
