Voice over LTE (VoLTE) faces a technology and marketing battle
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 [...]
LTE deployments continue to gather momentum, particularly in Asia Pacific
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 [...]
LTE and HSPA+ deployments gather pace
This year we will see both LTE and HSPA+ deployments becoming significant worldwide. LTE deployments are now gathering momentum although, as shown in the figure below, it is still early days with LTE. There have been 20 LTE networks commercially launched so far, in 14 countries. We expect more than 40 additional LTE commercial launches by [...]
GSA reports on HSPA+ and LTE developments
In March 2011, the GSA announced that 17 operators have already launched LTE services, including the USA, Germany, Austria, Denmark, Estonia, Finland, Hong Kong, Japan, Norway, Poland, Sweden and Uzbekistan. It also announced that 140 operators were committed to deploying commercial LTE networks. In April 2011, the GSA reported that HSPA services have now been [...]
Cellular network improvements will drive 3G traffic
3G enhancements, such as HSPA+ and LTE will be introduced on a widespread basis within the next five years, as shown in the table below. These enhancements will provide users with much greater peak speeds, which will better support usage-intensive services, thus helping to drive 3G traffic volumes. By September 2008, more than 94% of [...]
LTE deployment will start in 2010
LTE will be a major enhancement to 3G networks. It utilises a completely new modulation (for a 3G system) – OFDM – which has been widely adopted for WLAN (IEEE 802.11a/b/g), WiMAX, DVB digital terrestrial TV and DAB digital radio. While LTE can support narrower bandwidths than HSPA/HSPA+ (supporting bandwidths as low as 1.5MHz), it [...]
