Abstract :
Nowadays, Wireless Local Loop (WLL) systems due to its advantages in comparison with Wire Systems has become one of the first choices in technologies. In this paper a WLL network is presented. The scenarios were created in OPNET modeler as simulation tool to obtain the results. The proposal is based on the OFDM and CDMA technique. Providing QoS requirements like good throughput and minimum access media delay are challenging tasks with regard to 802.11e WLAN protocols and Medium Access Control (MAC) functions. We show that our simulation achieves supporting QoS for real time services.
