Coexistence issues and challenges amongst cellular, WiFi and WiMAX networks

The existing wireless data network standards are diverse and include those in 2.5G Wireless, 3G Wireless, beyond 3G Wireless, and there are various wireless standards which come under the IEEE 802 family include WiFi and WiMAX. These wireless standards can be classified according to their distance ranges in terms of wide area network, local area network, metropolitan area network, and personal area network. This paper includes the brief introduction to wireless data networks like cellular technology, WiFi and WiMAX. This paper mainly focuses on coexistence issues of 3G with WiFi and coexistence issues of 3G with WiMAX. It also provides the suitable solution to various coexistence problems.
