CDMA (Code Division Multiple Access) carriers such as Verizon Wireless Inc. and Sprint PCS Group have plans for EMS, supported largely by wireless technology company Qualcomm Corp., which owns most of the patents for CDMA. Boosted by a new branding deal with Verizon that lets LG InfoComm put its own name on Verizon phones, the company has plans for several new products in the next few months that take advantage of the WAP 2.0 browser and the upcoming CDMA 1xRTT networks, which support EMS messages more efficiently than current CDMA networks."The lack of backward compatibility between MMS handsets and non-MMS handsets will stifle MMS growth," said Nitesh Patel, an analyst at Strategy Analytics Inc., in Boston. "Without a mass of users with MMS handsets, it is unlikely MMS will take off rapidly. In this respect, EMS does have the advantage of being backward-compatible with current WAP devices. "However, with MMS allowing for greater sophistication than EMS, EMS has a short window of opportunity. Users will prefer the added sophistication of MMS," Patel said. LG InfoComms fall lineup for 1xRTT includes the VX4400, a dual-display phone with a full-color display. Along with supporting WAP 2.0, the phone includes Global Positioning System location-based technology; support for Qualcomms BREW, or Binary Runtime Environment for Wireless, development platform; basic text-only Short Message Service; and 64MB of internal memory. The phone can be programmed to change the color of the display when a call is coming in, and it includes the ability to record up to 2 minutes of the callers side of a conversation. Officials said that Verizon wants to start selling the phone by the end of the month but that next month is more likely. LG InfoComm has tentative plans to offer next year a camera phone in the United States that is currently marketed in South Korea. The KH5000 is a flip phone that features its camera in the phones hinge. Designed for third-generation CDMA 1xEVDO (Evolution Data Optimized) networks, the phone can transmit data at 2.4MB per second, although the future of 1xEVDO is unclear. The company has also developed a combination phone personal digital assistant called the VX9000. Related Stories:

"The only problem with the EMS solution is that it mostly runs over circuit-switched data today, which means that the more users, the more the network drainit ties up exactly the same network resources as a voice call," Kargos Kargman said. "This is being solved by 1xRTT."
