提出了一种分布式天线网络（DAN），以提高楼宇内无线业务的覆盖范围。具有高吞吐量的位置数量增加了一倍。详细分析了三天线DAN相对于单天线系统的性能改进，结果表明，单天线需要多10db的功率才能达到相当的性能。讨论了由DAN产生的额外延迟扩展的影响，并研究了它不降低性能的条件。
A distributed antenna network (DAN) is demonstrated to improve the coverage of in-building wireless services. A doubling in the number of locations with a high throughput is achieved. A detailed analysis of the performance improvement of a three-antenna DAN over a single-antenna system shows that 10-dB more power would be required from the single antenna to achieve a comparable performance. The effect of the additional delay spread generated by the DAN is also discussed, and the conditions under which it does not degrade performance are investigated.
