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...

The end of 2G

The end of 2G

Several operators world over have announced intentions or plans to shut down their 2G networks. The timeframe indicated for this possible shutdown is around 2017-18 timeframe. As wireless carriers are likely to go ahead with their plans, there could be a number of implications for the industry. While we have about five years before the proposed shutdown takes place, it is important to take stock of the current role of 2G networks. 2G networks typically operating in the 850/900 MHz bands have been pivotal in providing close to 100% geographical coverage due to the better propagation characteristics they offer compared to the 2,100 MHz at which 3G operates.  2G is also cost effective in comparison to 3G as its propagation characteristics ensure equivalent coverage with fewer base stations.  This is especially true in areas where the density of users is lower as the economics of providing ubiquitous coverage are much better in 2G. In addition, 2G networks still carry a bulk of the voice calls in many networks.  This...
