摘要

本文探讨了宽带固定无线应用中系统架构的考虑。本文进一步探讨了优化部署频谱效率和最大化用户可用带宽的解决方案。本文提出的系统解决方案在MMDS频段使用FDD信道化和TDMA协议，也适用于3.5 GHz范围。有两种变体，单个的Supercell和细胞类型的Multicell。Supercell以点对多点的方式有效地部署在世界各地。本文综述了两种不同蜂窝结构的部署考虑、辐射模式和特点。这些蜂窝的性能特征包括:覆盖范围、可用性、误码率、重用性和频谱效率。对蜂窝型应用的天线性能进行了评估，重点是干扰。

A system architecture to maximize broadband fixed wireless capacity

This paper explores system architecture considerations in a broadband fixed wireless application. This paper further explores solutions that optimize the spectral efficiency of a deployment and maximize the bandwidth available to a subscriber. The system solution presented here uses FDD channelization and a TDMA protocol in the MMDS band and is applicable in the 3.5 GHz range, also. Two variants are presented, a single Supercell and a cellular type Multicell. The Supercell has been effectively deployed worldwide in point to multipoint fashion. This paper reviews deployment considerations, radiation patterns and the characteristics of the two different cell structures. Performance characteristics of these cells are included: range, availability, BER, reuse and spectral efficiency. Antenna performance is evaluated for cellular type application with a focus on interference.
