摘要
介绍了天线专家公司提供的EIA型蜂窝中继器的设计概念和应用。随着大型城市系统的成熟,客户希望覆盖范围越来越远,一直延伸到郊区。另一方面,正在发展的农村系统可能只需要足够的用户来建立一个单独的蜂窝基站。这两种系统都将受益于一个可以显著扩大覆盖范围的助推器,但成本仅为传统蜂窝站点的一小部分。extended - a - cell IV高功率中继器系统在设计时就考虑到了这些应用。高功率、频率转换蜂窝中继器设计用于显著扩展蜂窝站点的覆盖范围。该中继器频率灵活,可转换,完全远程控制,与早期需要供体细胞分割的助推器不同,无需系统修改。
The design concepts and applications of an EIA type-IV cellular repeater being offered by the Antenna Specialists Company are described. As large metropolitan systems mature, customers expect coverage further and further out into the suburbs. Rural systems under development, on the other hand, may project only enough subscribers to justify a single cell site. Both of these systems would benefit from a booster that would significantly extend coverage, but cost only a fraction of the amount of a conventional cell site. The Extend-A-Cell IV high power repeater system has been designed with these applications in mind. The high-power, frequency-translating cellular repeater is designed to significantly extend the coverage range of a cell site. This repeater is frequency-agile and translating, completely remote controlled, and unlike earlier boosters that required donor-cell sectorization requires no system modifications.<>
