Nettech Systems introduced a communications solution called Smart IP that enables Internet and intranet applications to run over wireless networks without the challenges associated with Transmission Control Protocol/Internet Protocol (TCP/IP) connections. The TCP/IP protocol was designed for high-speed wired networks and assumes they are connected to the network at all times-constantly sending acknowledgements to confirm the connection.
If the connection is severed, it then reconnects and resends all the data. However, mobile data users are not connected to the network at all times and thus don’t need the TCP/IP connections.
Not using TCP/IP cuts down on airtime expenses and extends device battery life, said Nettech. It also reduces the number of packets sent by as much as 80 percent and cuts the amount of data transmitted by 30 percent to 60 percent.
U.S.-based GTE Wireless and Canada’s Sierra Wireless Inc. announced their combined circuit-switched Cellular Digital Packet Data (CDPD) solution is commercially available. The product uses Sierra Wireless’ MP215 modem, the first modem to retain packet data connection seamlessly between circuit-switched cellular networks to CDPD networks. GTE Wireless is the first network provider to offer the solution.
Canada-based TMI Communications announced its new Specialized Services packet data mobile communications solution is available in all 50 U.S. states as well as Canada, Mexico and the Caribbean. The Specialized Services messaging protocol uses TMI’s MSAT geostationary satellite and terrestrial packet data network. Its coverage range is being marketed particularly to the transportation and fleet management industries.
Motorola Inc.’s Cellular Infrastructure Group said it is deploying data and fax capabilities on commercial CDMA wireless networks. Motorola CIG is deploying circuit-switched data in networks in Japan, South America and the United States. GTE plans to test the service on its U.S., Motorola said.
