cial networks are expected towards the end of 2011. With all the hype around LTE, the operators cannot lose focus on their existing 3G investments. The UMTS operators are continuously upgrading their existing 3G networks to HSPA + and exploring the possibilities with dual-carrier HSPA. Some key announcements from the industry during 2008-2010 on LTE are as follows: According to Informa Telecoms & Media the emergence of LTE is causing a major reshuffle in the distribution of IPR wealth. For 2G and 3G it was primarily dominated by Qualcomm, Nokia, and Ericsson but for LTE the company believes that more than 60% of LTE patents from likes of Qualcomm and Nokia, 50% of LG's portfolio, 40% of Samsung's patents, and less than 33% of Ericsson's portfolio could be described as essential LTE patents (May 2010).

GSMA (GSM Association) adopted One Voice as the official solution for its Voice over LTE (VoLTE) initiative, effectively shutting out rival industry group VoLGA (Voice over LTE via Generic Access) in February 2010. Nordic carrier TeliaSoneria launched the world's first two commercial LTE networks in Oslo and Stockholm in December 2009. Qualcomm's started sampling of MDM8220 chipset that supports dual-carrier HSPA+ and 3G25 /LTE multimode MDM9200 and the MDM9600 chipsets. These chipsets enabled devices are expected to be available in the second half of 2010 (November 2009). picoChip releases LTE femtocell development kit (September 2009). Verizon Wireless tested data connections on LTE network in Seattle and Boston in 700 MHz. The company is p
