Performance and capacity evaluations of DECT, PACS, and PHS standards for wireless local loop applications

In this paper performance and capacity of the three standards for wireless local loop (WLL) applications have been investigated, both qualitatively and quantitatively. The qualitative evaluation consists of detailed comparison of parameters of each standard and their relevance in WLL applications. In the quantitative analysis detailed simulations have been performed covering diversified sets of conditions. The results of both types of analysis are presented. A major conclusion is that all three standards provide satisfactory performance for WLL applications. For low traffic environments PACS which can employ larger cells perform better than the other two standards. In suburban areas where in addition to coverage capabilities capacity is an issue, DECT has better performance. For high traffic density urban areas with great capacity requirements the three standards all have good performance
