A comparative evaluation of DECT, PACS, and PHS standards for wireless local loop applications

In a comparative analysis performance and capacity of DECT, PACS, and PHS f or wireless local loop applications have been investigated. This article re ports the results of both qualitative and quantitative analyses. The qualit ative evaluation consists of a detailed comparison of the parameters of eac h standard and their relevance in WLL applications. In the quantitative ana lysis detailed simulations were performed covering diverse sets of conditio ns. The results of both types of analysis are presented. A major conclusion is that all three standards provide satisfactory performance for WLL appli cations. For low traffic environments PACS, which can employ larger cells, performs better than the other two standards. In suburban areas where, in a ddition to coverage capabilities, capacity is an issue, DECT has better per formance. For high traffic density urban areas with great capacity requirem ents, the three standards all have good performance.
