چکیده

In this letter, the influence of the downlink average ratio of the other cell interference to other-user interference in the serving cell (DARI) on the distributed repeater system (DRS) performance is analyzed. It is found that the improvement of DARI depends on a propagation path loss environment. Applying the computed DARI to a 3-RS DRS cell, as high as 13.9% capacity enhancement was obtained when the path loss exponent is 4.5. In addition, by using the power allocation equation, it is expected that a hexagonal DRS cell without coverage holes or excessive coverage overlap can be realized. key words: WCDMA, distributed repeater system (DRS), distributed antenna system (DAS), base station, repeater

Applicability of repeaters for hotspots in UMTS

The aim of this paper is to assess the applicability of repeaters for downlink capacity improvement in hotspots through field measurements. Deployment of repeaters in capacity-limited scenarios requires more careful radio network planning compared to the traditional approach for operation in coverage-limited environment. The results of the field measurements conducted in an urban UMTS network r...
