The GSM (Global System for Mobile communications) cell phone standard, which is more popular in Europe, will continue to see steady expansion until 2007 as consumers migrate from older technologies, the study showed. But from 2008 onwards, GSM is expected to see a decline in market share as operators shift to wideband CDMA (Code Division Multiple Access), the cell phone standard that is popular in the Americas and parts of Asia. "While GSM will remain the dominant airlink throughout most of the forecast, CDMA airlink standards will pass GSM in 2009 to claim the largest share of the market in terms of number of subscribers," Ken Hyers, a senior analyst at In-Stat, said in a statement.

The U.S, subscriber base should rise at a compounded annual growth rate of 5.6 percent through 2009, with CDMA remaining a dominant technology, In-Stat said, GSM will gain, mainly at the expense of TDMA (Time Division Multiple Access), which is likely be phased out by 2007, GSM growth will slow down after 2007, hustle iphone case as subscribers turn to wideband CDMA, the study said, Meanwhile, the number of mobile phones shipped in 2004 is expected to reach 625 million, according to a study released this week by iSuppli, That compares with 520.8 million units shipped in 2003..

Worldwide subscriber numbers projected to jump from 1.5 billion in 2004 to more than 2.5 billion in 2009, fueled by CDMA. China leads in terms of overall subscriber growth, but other countries like India are quickly picking up the pace, In-Stat/MDR said in the study, which was released this week. The market is witnessing strong growth after suffering from the economic downturn, the report said. India is expected to fuel global subscriber growth. In Europe, the growth will be slower as markets mature, particularly in Western Europe, the market researcher predicted.

Another signaling protocol, , has also been proposed as a solution to this problem. But with GMPLS, which works using light paths, it can take anywhere between several seconds and several minutes to install or remove an optical connection. Checking aheadJIT is faster, supporters claim, because it doesn't wait for acknowledgements from destination devices when it configures the addition to a network. Most protocols--Asynchronous Transfer Mode (ATM) and GMPLS, for example--send a signal ahead to alert devices to incoming traffic. Before data is sent, the sender must receive confirmation that these devices are ready. By contrast, JIT sends out messages that nail up the connections as it goes, then transmits the data without waiting for confirmation.
