IEEE 802.16e mobile WiMAX standard provides a promising technology for broadband wireless access. Owing to the limited bandwidth resource and increased data-rate requirement, some sort of mechanism is essential to achieve good spectral efficiency and to better manage the limited resources of bandwidth. Link adaptation technique helps in meeting out these demands and has now emerged as one of the powerful tools for future wireless broadband networks. Here, the authors propose a modified layer design architecture that utilizes adaptive modulation and coding to provide link adaptation in mobile WiMAX network and also determine the number of supportable users with the consideration of a variety of real-time and non-real-time services for a mixed type of subscribers.
