Just a few weeks ago, at the beginning of the year, the number of mobile connections around the world reached 4 billion. That means it's been less than 18 months from when the industry reached the 3 billion connections mark in the third quarter of 2007.

On a global basis, connections growth is accelerating rapidly, according to industry global database Wireless Intelligence. And they believe that the next billion global connections could be achieved by the third-quarter of 2010. This new growth is reportedly being driven by developing countries. Asia-Pacific, including China and India, as well as African regions now account for over half of all global connections.

The report says GSM remains the dominant network standard accounting for 81 percent of connections. In the U.S.,

But, the GSM standard's share in more developed markets is shrinking as customers migrate to the WCDMA family of technologies, the primary migration path for GSM operators. In Western Europe, GSM now accounts for less than 75 percent of connections, with WCDMA and WCDMA-HSPA taking a significant share of the new additions.

WCDMA connections are expected to swell considerably this year as operators in China and India switch on their first WCDMA networks, while some operators that are belatedly moving to the technology -- T-Mobile USA, for example -- are moving directly to WCDMA-HSPA.

The WCDMA family of technologies increased its global market share from 5 percent to 7.9%. It is expected to account for 12.8% of all connections by the time the market reaches the 5 billion mark. By then, GSM is should account for approximately 77%.

The CDMA family of technologies has seen a similar migration to high-speed networks. Growth has been largely concentrated here in North America via

CDMA connections have also been declining in Latin America mainly due to
