Estimating the consuming resources of IEEE 802.16e cell in case of video conference application

Abstract IEEE 802.16e is a WiMAX standard which mixes between broadband and wireless. It is based on OFDMA and provides large capacity as compared with other standards that support previous technologies. One of IEEE 802.16e features is to provide quality of service (QoS) as service classes. However, real time applications are a real challenge for systems capacity due to consume heavy data rate such as video conference application. The service classes of 802.16e standard are depended on minimum reserved traffic rate to submit the service. This paper estimates the consuming resources of 802.16e cell during providing video conference service taking into account the minimum reserved traffic rate of service classes related to real time applications and other factors.
