In the quest for substantial increases to the capacity and throughput of mobile networks, unlicensed radio spectrum is expected to have an important role in 5G systems from 2020. However, work is already underway in 3GPP to allow 4G LTE-Advanced networks to take advantage of unlicensed spectrum much sooner. The Licensed Assisted Access (LAA) feature will… Read more
One of the major features of LTE-Advanced is Carrier Aggregation, which allows mobile network operators to combine a number of separate LTE carriers. This enables them to increase the peak user data rates and overall capacity of their networks and to exploit fragmented spectrum allocations. I introduced the fundamentals of Carrier Aggregation in a previous… Read more
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… Read more
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… Read more
This month, the GSA provided its latest data on LTE launches, showing that LTE deployment continues to gather pace worldwide. By the end of August 2011, 26 commercial LTE networks had been launched. The GSA expects at least 93 LTE networks to be in commercial service by the end of 2012. It was a particularly… Read more
The momentum behind LTE is increasing, in terms of mobile network operators launching LTE services or announcing an intention to launch LTE services. However, one of my biggest fears is that operators will rush to make high-profile press announcements to say that they have launched LTE, while avoiding any commitment to invest substantially in LTE… Read more
As part of its announcement of the launch of its LTE network, SK Telecom in South Korea provided information on mobile data traffic, which is continuing to increase substantially. SK Telecom said that monthly data traffic recorded in June 2011 was 19 times greater than in August 2010. It predicts that the “dramatic” increase in… Read more
There have been a number of recent announcement of LTE launches in 2011: At the end of April 2011, TeliaSonera launched a commercial LTE service in Lithuania. Canadian mobile network operator, Rogers Communications has confirmed plans to launch an LTE network in 2011. South Korean operator, SK Telecom plans to launch 4G LTE services in… Read more
Mark Heath looks forward to 2011 and the continued progress of LTE and femtocells. He comments on the launch of 4G services by NTT DoCoMo and AT&T, and discusses SK Telecom’s deployment of femtocells, specifically to solve congestion issues. As 2011 starts, I would like to wish all our readers a great New Year! This… Read more
With many operators desperately searching for ways to increase non-voice revenue, the world’s top ten non-voice services have been identified in the report, The World’s Top Ten Non-voice Services for Mobile Operators, written by Unwired Insight. “With falling voice ARPUs, mobile operators now need to drive non-voice services”, says co-author Dr Alastair Brydon. “From a… Read more
