4Q07 was another strong quarter for HSPA deployments, with 8 HSDPA and 9 HSUPA deployments. More than half of the HSUPA deployments for the quarter were in Western Europe, which is no surprise, given that Western Europe is a hotbed for WCDMA/HSDPA, and Western European operators are now embracing HSUPA to add throughput on the uplink. Comparatively, there were 6 EV-DO Rel 0 and 6 EV-DO Rev A deployments, with most of these deployments occurring in Eastern Europe and in the Middle East & Africa regions. There were 6 Mobile WiMAX deployments, with half of these occurring in the Latin & South America geographic segment.
3G/4G subscribers (i.e., those subscribers to WCDMA/HSPA, EV-DO, TD-SCDMA, Mobile WiMAX, and LTE networks) grew 91% over the course of 2007, and we expect a 63% growth rate over the course of 2008, with subscribers expected to rise from 230 million in 2007, to 375 million in 2008.
