Planning and Sizing Tool for WiMAX Networks

Abstract

Abstraet-A software tool for planning and sizing Wireless Networks based on standard 802.16 is presented in this paper. Due to the deployment of communication systems based on this standard, it is necessary a tool which allows an easy implementation and sizing of this type of networks. With this tool the user will be able to define technical specifications of transmitters and receivers, design parameters of the network and different propagation models, and evaluate point to point links and point to multipoint networks, obtaining results such as losses in the link, power received, signal noise rate, coverage or bit rates the network is able to handle. The versatility of the tool has been contrasted with experimental results obtained in a real deployment in a rural zone in Spain.

Planning of Relay Station Locations in IEEE 802.16 (WiMAX) Networks

“…The solution gives us the number and placement of the RSs, the used links, and the rates of the links. In real life, there is a grounds survey which precedes a network deployment [10], [11], [12]. Based on the links characteristics (including SNR measurements and distance between the nodes), the maximum rates for every link are found (m…”

Modelling and planning fixed wireless networks

“…The use of automated planning and modelling in aiding the design of wireless communications networks has become widespread, though primarily in the area of mobile telephony, specifically GSM [1,2] and UMTS [3][4][5][6], but also for generic broadband fixed wireless access (BFWA) [7], WiMAX [8] and WLAN [9,10]. Although the main use of automated planning, including the use of mathematical programming techniques [2,11], has been in producing and configuring individual networks, they also have an important role to play in evaluating different economic and technical scenarios.…”

Medium access control and network planning in wireless networks

“…However, for simplicity, we assume that the maximum rate changes with distance. In real-life scenarios, there is usually a field survey which precedes the network deployment (92), (93) and (94). The link rates are selected based on the links characteristics such as, the SINR (Signal-to-Interference-plus-Noise-Ratio), fading, the specifics of the terrain and interference with other wireless systems.…”
