IEEE 802.16e

IEEE 802.16e is a standard of telecommunication for data-processing networks but also an work group of the IEEE 802.16 charged to develop the standard Mobile WiMAX. This one was approved on December 7th, 2005 and allows, contrary to the standard IEEE 802.16a or IEEE 802.16d which authorizes only one fixed connection between transmitter and receiver, displacement in the integrality of an coverage area to another without disconnection.

Description

IEEE 802.16e was published on February 28th, 2006. This one envisages, starting from a basic station towards mobile customers moving with less than 120 km/h, the data transmission with flows up to 30 Mbps on a waveband ranging between 2 and 6 GHz (coverage area of a ray lower than 3,5 km).

This standard makes it possible to mix the coverage areas by Interopérabilité between fixed connections and mobile connections. In the same way, this one gives the possibility to the mobile customer of passing automatically from a station to another without loss of connection (Roaming).

On the level of the physical interface PHY, IEEE 802.16e uses the modulation OFDMA (Orthogonal Frequency Division Multiple Access) which makes it possible to adopt the channels in a dynamic way.

Applications

The standard IEEE 802.16e extends the possibilities of fixed WiMAX thanks to mobility. This one allows:

  • to bring mobility to WiMAX Fixes while being interopérable with this one;

  • telephony on IP or VoIP;
  • the use of mobile services high banc;
  • etc
