DECLoop does not require any sort of frequency planning, but in order to have a reliable system with minimum cost, network planning is an essential issue to any kind of wireless networks. Coverage analysis, Interference analysis, Traffic analysis and Air interface analysis must be done simultaneously. These are dependent functions with mutual effects and doing simultaneous analysis makes network planning more complex. The best solution is proprietary simulation tools that are specifically designed for the communication systems to be used. There are three stages that network planning can be used: 1) Pre-Sales planning which is a course pre-tender plan to prepare the right LOM. 2) Post-Sales planning which is Fine plan to meet required specifications and to optimize the Performance. 3) Future Expansion to optimize the network in future DECSim: Network Planning Tool BBS Access, the equipment provider for this proposed project, has designed a state of the art in house simulator for its DECLoop WLL equipment called DECSim. This simulator will be used for simulating various network designs to be used in the implementation of the proposed network. DECSim is a powerful, fully integrated network simulation package for design of large-scale wireless DECT based communication systems. It integrates three simulation tools into one package that can perform simultaneous traffic, RF propagation, and DECT air interface simulations. It is Applicable to small as well as large-scale problems with tens of thousands of transmitters, it is equally useful for rural and dense urban environments. Designed specifically for DECLoop equipment, DECSim is easily adapted for analysis and design of any DECT based communication system. Here are some major DECSim functionalities: • Coverage Analysis • Air Interface and Interference Analysis • Traffic Analysis Various kinds of traffic simulations, as well as air interface/RF simulations can be performed. Some example results of these simulations are presented here. |
