The cost of using IEEE 802.16d dynamic channel configuration

Abstract:

Ubiquitous broadband Internet access is an important requirement to satisfy user demands and support a new set of real time services and applications. IEEE 802.16, as a Broadband Wireless Access technology, can significantly contribute in this area. It is able to provide high throughput over large distances, with intrinsic QoS support, in Line-of-Sight and Non-Line-of-Sight environments. This paper discusses a network architecture, based on IEEE 802.16d compliant equipments, which is able to support real-time services with QoS integration through dynamic configuration of the 802.16 channel, using the NSIS framework. Tests have been carried out to evaluate the QoS performance of the defined architecture, demonstrating that it is perfectly capable of handling and supporting real time services, using dynamic configuration of the 802.16 channel, without introducing an excessive cost in the network. ©2008 IEEE.
