3GPP Long Term Evolution (LTE), is the latest standard in the mobile network technology tree that produced the GSM/EDGE and UMTS/HSPA network technologies.
The Global Mobile Suppliers Association reported on Tuesday (April 5) that 196 carriers in 75 countries are investing in LTE at some level. The report says 140 of those operators will deploy commercial LTE systems in 56 countries, up 118 percent from a year ago, and 56 other carriers are conducting LTE trials. It estimates at least 73 LTE networks will be in commercial service by the end of 2012.
It will extend from end user data plans to cellphones, back-end systems and the chips, IP cores and patents that make them work. But it remains to be seen just how those changes will play out.
