Abstract
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.
