Growth in technology has led to unprecedented demand for high speed Internet access. IEEE 802.16e (mobile WiMAX) is a wireless communication standard with high data transfer rates and good performance. It not only is efficient as compared to its counterpart technologies today (Wi-Fi and 3G), but also lays the foundation for 4G mobile communication. In 4G wireless communication systems, bandwidth is a precious resource, and service providers are continuously met with the challenge of accommodating more users within a limited allocated bandwidth.
