Since I wrote my previous post on the capabilities of HSPA+, LTE and LTE-Advanced, SK Telecom has announced the world’s first end-to-end commercial implementation of LTE-Advanced. Other network operators, including Verizon, AT&T and NTT DoCoMo, have announced plans, trials and network implementations of LTE-Advanced, but SK Telecom is the first to offer a commercial service with mobile…

Last week I was interviewed for a forthcoming report on mobile network sharing and it prompted me to catch up on the latest 3GPP developments in this area. As network sharing becomes widespread in the mobile industry, a range of new capabilities are under development in 3GPP. These will provide network operators with much greater…

The latest “Evolution to LTE Report” from the Global mobile Suppliers Association (GSA) includes, among other things, a (very short) list of Voice over LTE (VoLTE) launches around the world. Over two years ago I expressed my concern at the lack of long term solutions for voice over LTE. While the situation is gradually becoming clearer, there is…

One of the major themes of 3GPP Release 12 (due for completion in 2014) is enhanced support for small cells in LTE. With mobile network traffic expected to increase dramatically over the coming years, the ability to reuse spectrum many times in dense usage areas will make small cells crucial. In a previous post on…

Working in the UK, where commercial LTE services are still not available, it is easy to forget that standardisation of LTE has been underway for many years. The first 3GPP standards were frozen way back in 2008, in 3GPP Release 8, and no fewer than five 3GPP releases containing LTE aspects have now received attention…
