Enhancing Wi-Fi with IEEE 802.11u for Mobile Data Offloading
Apart from voice services, data made its foray in cellular networks with 2.5G networks. Today, with 3G network already in place, the data requirements of mobile subscribers is very high. With the increasing demand for mobile internet and rich data services such as streaming media for audio and video, this data requirement is expected to multifold in near future. Correspondingly the network operators have started looking for alternative means of satisfying these data needs. Among many alternatives, Mobile Data Offloading (MDO) is the most promising one. This paper presents the extensive need, benefits, and technological solutions for MDO.
