Throughput Utility Enhancement of Cognitive Wimax With Femto-Cells
WiMAX with femtocells is a cost effective and spectrally efficient next generation broadband wireless communication systems. Femtocells are perceived as having a strong potential to provide high data-rate services with increased coverage at low cost. Femtocells will allow new services and business models to be offered to indoor users. Almost parallely, the WiMAX standard has emerged as a potential candidate technology for the future wireless networks. WiMAX femtocells are currently under development and will therefore play an important role in the world of indoor broadband wireless access. However, several aspects of this new technology, such as the access method and interference avoidance techniques play a crucial role in the amount of interference caused to co-channel deployed macrocells.
