In 2006, GSM is the dominant cellular technology, but by 2012, WCDMA will receive the highest CAPEX investment by mobile operators, according to ABI Research. By 2012, worldwide mobile CAPEX will exceed $150 bln. In 2005, China Mobile’s CAPEX in China was $8.86 bln, more than Vodafone’s global total CAPEX ($8.74 bln), which is remarkable considering the high value of CAPEX spent per-subscriber and per service revenue dollar generated. In North America, Cingular’s CAPEX investment in 2005 was $7.475 bln, 116% more than in 2004. This was due to Cingular’s investments in building out its WCDMA network.
