Abstract :
The increasing development of mobile applications has changed the traditional demands of computer networks, which must now provide ubiquitous broadband wireless communication. In this context, IEEE 802.16 standardizes the physical and medium access control layers of the technology, aiming to allow network access in both nomadic and mobile scenarios. In this work we analyze the impact caused by overhead on the bandwidth allocation mechanism of WiMAX networks. Our main focus is to evaluate the number of SSs that can be served, and the influence of adaptive modulation and coding configuration. Finally, we discuss the importance of considering physical impairments in the process of designing a broadband wireless access network.
