The GSA expects that by end-2010 there will be 15 LTE networks in commercial service, and by end-2012 a total of 33.
Most significantly, the LTE deployments are taking place in several frequency bands, currently ranging from the 700 MHz to 2.6 GHz. A major benefit of this approach is that this way the new roll-outs will not disrupt the existing UMTS services.
The Global Mobile Suppliers Association (GSA)—an industry group representing the leading UMTS vendors—has released an information paper on the global status of current long-term evolution (LTE) network trials and deployments. According to the study, as of 28 October operators had confirmed a total of 42 LTE network commitments in 21 countries. The GSA expects that by the end of 2010 there will be 15 LTE infrastructures in commercial service, with the number reaching 33 by the end of 2012.
