Managing Expanding Mobile Data Traffic
Based on extensive research for ABI Research’s “Carrier Strategies to Alleviate the Capacity Crunch” report, ABI details the strategic options mobile carriers can place at their disposal to manage the expanding mobile data traffic outlook.
- Radio Access Technology Options: Carriers are commercializing LTE but there are additional benefits to be gained from quickly adopting the LTE-Advanced roadmap. LTE-A’s release 10 introduces enhanced Multi-In Multi-Out antenna technology as well as interference mitigation technologies such as CoMP and eICIC. A crucial technology is Carrier Aggregation that will allow mobile operators to “chain” spectrum blocks for substantial capacity and speed gains.
- Network Architecture Options: Mobile operators can optimize their network base station assets to make the best possible (re)use of their allocated spectrum. As of 1Q-2013, only a handful of mobile operators have fully engaged on a small cell strategy that incorporates Wi-Fi hotspots and small cell 4G LTE base stations. Operators that have adopted a comprehensive small cell strategy include Softbank NTT DoCoMo, SK Telecom, KT, Uplus and in the last week, Verizon Wireless.
- Spectrum Options: After speaking with various spectrum stakeholders, ABI Research estimates that the available spectrum for the mobile cellular community will increase from around 300 MHz to 1,500 MHz over the next 5 to 10 years. Incumbent mobile operators and equipment vendors would prefer this spectrum to be allocated on a dedicated basis but the FCC, the EC, Ofcom, and a number of additional governments are keen to evaluate cognitive radio technologies, such as white space TV, as they would boost spectrum capacity while allowing co-habiting users. At the next World Radio Congress there would be a stand-off between cellular and broadcast stake-holders.
