Planning of WiMAX networks


Application

Broadband wireless access systems are more and more important in the area of mobile communications. They enable subscribers to have a high speed data connection at home, in the office, or wherever they go.

WiMAX is a new technology, which is specified in IEEE 802.16. It is a high-capacity IP-based technology, based on open standards to be deployed either as a new network installation or as an overlay to complement existing 2G and 3G wireless air interfaces.



WiMAX networks

High speed internet access, new multimedia services and applications are supported by WiMAX.
Depending on the mobility of the subscribers, there are two sub-standards of WiMAX:

  • Fixed WiMAX (IEEE 802.16-2004) for all stationary (or nomadic) subscribers
  • Mobile WiMAX (IEEE 802.16e) for all mobile subscribers (incl. handover between different cells)
Equipment with multiple advanced antenna capabilities - MIMO and beamforming - will be integrated for higher throughput and capacity in the next generation of WiMAX networks.

Propagation Models for WiMAX


Propagation models must be adapted to the requirements of WiMAX. And this is more than only calibrating existing models for new frequency bands.
WiMAX requires predictions on multiple heights (e.g. inside buildings) or on prediction heights relative to the roof top level (for fixed WiMAX installations).

Network Planning for WiMAX


Network Planning Modules must be able to handle the flexible and adaptive air interface of WiMAX.

This is in combination with the multi service conpcet of WiMAX a big challenge  for the network simulators.

Features

Features of the WiMAX module at a glance:

  • Coverage analysis based on accurate Point to MultiPoint propagation models
  • Simultaneous prediction of signal level on multiple heights
  • Supports nomadic/mobile (IEEE 802.16e) as well as stationary/fixed (IEEE 802.16-2004) applications
  • Supports both frequency bands (below 11 GHz and 10-66 GHz)
  • Consideration of downlink and uplink in network planning
  • CoChannel Interference anaylsis
  • Coverage analysis (incl. fast fading margin)
  • Required Tx power in up- and downlink 
  • Multi-Service concept allows user-defined services   
  • Easy handling of the databases
