Wi-Fi Offload

Wi-Fi Offload

Smartphones growth is demanding higher data usage with 3G and LTE, this data usage is expected to explode going forward. Mobile industry has been looking at using Wi-Fi as a complementary access technology. With the advent of dual-mode handsets, Wi-Fi has become an access network alternative primarily to enhance coverage in doors. Current estimates show already more than 60% of content delivered to smartphones is provided over Wi-Fi access networks. Challenges Making Wi-Fi Offload Secure & Automatic Making Carrier Services Available on Wi-Fi Enhancing Network Discovery & Selection Monetizing Wi-Fi Hotspots Forging Partnerships across the Wi-Fi Ecosystem ePDG (LTE & eHRPD) and Wi-Fi Offload Non-3GPP accesses can be split into two categories: the “trusted” ones and the “untrusted”: Trusted non-3GPP accesses can interact directly with the EPC (Enhanced Packet Core) LTE network. Untrusted non-3GPP accesses interwork with the EPC via a network entity called the ePDG (for Evolved Packet Data Gateway). The main role of the ePDG is to provide security mechanisms such as IPsec tunneling of connections with...

Mi-Fi: The new extension to the ubiquitous Wi-Fi

Mi-Fi: The new extension to the ubiquitous Wi-Fi

In an era where radio spectrum is rationed out to the operators by the government, more stringent is the case in emerging countries such as India, innovative uses of the available spectrum is the order of the day. One such technology is the use of ubiquitous Wi-Fi access points at home or office which in turn is connected to the Digital Subscriber Line (DSL) landline connection. Popularly known as “Wi-Fi off load”, this is a method by which the data traffic is diverted from the carrier’s macro cellular network to a localized Wi-Fi network, installed typically in homes, enterprises or public locations, thus relieving the licensed spectrum used.  Such Wi-Fi hot spots can be deployed by the owner of the venues as “Private hot spots” (e.g. homes, office premises, Cafes and Restaurants such as Starbuck, Costa Coffee, hotels); or by the Internet Service Providers (ISPs) as “public hotspots” typically in areas such as Airports and Malls; or mobile operators either by themselves or in partnership with ISPs as “carrier...
