Optimization of W-LAN networks

Network Optimization


In order to refine the WLAN configuration an optimization module is included in WinProp. This module automatically selects the best locations for the installation of access points out of a predefined set of possible locations for access points. To describe the requirements of the deployed network, a priority map may be used. Therefore the optimization modules can consider location dependent traffic, if the users are not homogenously distributed in the scenario. So hot spots can be modeled and considered during the optimization process.

The optimizer was published at the 60th IEEE Vehicular Technology Conference (VTC) 2004 in Los Angeles (CA) in the paper
Automatic Optimization Algorithms for the Planning of Wireless Local Area Networks.

 

More information about the optimizer module for WinProp is available on a separate page.



Algorithms





The optimization consists of several steps:

  • First of all the predicted coverage of every potential transmitter is assessed.

  • Then the density of the given transmitters is reduced.

  • Finally out of the remaining sites a combination is searched which fulfills the given requirements. This step includes the application of a carrier assignment in order to minimize the co-channel interference.

  • The result of the optimization is a reduced selection of transmitters which takes into account the required signalpower to be received and the interference situation.

Winprop supports all sub-standards of IEEE 802.11 (a/b/g) as well as air interfaces like HIPERLAN/2

W-LAN Planning




ProMan can be used for the planning of W-LAN networks. Max. achievable data rates as well as SNIR and required Tx powers can be predicted. 

Path Loss Analysis 




With ProMan the prediction of the path loss for the whole area inside the building (multi-floor buildings are supported) is possible for each access point individually.

Highly accurate deterministic prediction models provide a detailed analysis of the mobile radio channel. They consider the building structure as well as the material properties of the different objects (walls, doors, windows, ...).
