Rich Communication Services

Today in this digital world, almost everyone wants to be connected from anywhere and anytime. This is leading to high data usage day-by-day. People are looking for unified communication services beyond voice and SMS/MMS. Over-The-Top players like Skype, Whatsapp have maximized their business by provided IP based chat and call services. Even though the market needs are addressed by the OTT players, OTT couldn’t guarantee QoS, security and interoperability. On the other hand operators started losing revenue to OTT players. For example, an OTT provider named KakaoTalk has been extremely successful with its messaging services, supporting 37 million users in Korea and 46 million globally. Therefore, Korean service providers are “experiencing difficulties, including decreased SMS revenues and increased network investment cost to accommodate surging traffic,” per South Korean service provider.

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...
