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

In a comparative analysis the performance and capacity of DECT, PACS, and PHS for wireless local loop applications have been investigated. This article reports the results of both qualitative and quantitative analyses. The qualitative evaluation consists of a detailed comparison of the parameters of each standard and their relevance in WLL applications. In the quantitative analysis detailed simulations were performed covering diverse 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, performs 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.
