Broadband wireless access systems usually provide flexible sleep-mode operations for mobile stations to conserve their energy during idle or active mode. For example, Mobile WiMAX, i.e. the IEEE 802.16e, offers several power-saving classes that can be associated with different types of network connections to minimize power consumption of mobile stations. Unfortunately, previous studies did not ...

The fixed broadband market is converging with the world of fixed wireless solutions under the umbrella of broadband wireless. Companies are offering a variety of different service technology options to the market that may compete or work in conjunction with each other to meet user requirements for higher bandwidth lower latency solutions, differing in terms of their degree of mobility, level of...

One of the key questions operators must address prior to setting up a Mobile WiMAXTM network is whether to deploy a centralized or distributed network architecture. While a centralized topology is far more prevalent than its counterpart, the distributed approach is an up-and-coming alternative deserving serious consideration. As a world leader in WiMAXTM, Alvarion works closely with operators t...
