The U.S. Mobile Messaging industry generated revenues of $571 million in 2000 and is projected to surpass $5 billion by 2007. But growth is becoming increasingly hindered by interoperability snafus, according to analysis from Frost & Sullivan

Competing technologies like GSM, CDMA and TDMA have led to closed messaging platforms -- a plague for the expanding market. Furthermore, short message services (SMSs) usually use SMTP to transmit data within their own networks. SMTP does not allow inter-network connectivity.

Because of the lack of interoperability, phone and device manufacturers are developing products that only work on these private networks, compounding the scope of the problem.

Device interoperability in the wireless market can rarely be expected, but it is unclear when vendors might settle on a standard protocol.
