Communications Mediums
Wireless Network Transparent
The Fleet.NET™ product suite is designed to be independent from any specific wireless medium. This allows customers to select the wireless communications medium that best suits their geographic and functional requirements. This also provides the flexibility to change communications networks, should those geographic or functional requirements change.
Compatible Network Types
Fleet.NET™ products are designed to operate over most popular wireless packet data networks. These networks are designed specifically to carry data with a high degree of reliability. Most such networks charge a monthly fee for access that is based upon the amount of data sent between the vehicles or field people and the office. Most wireless data carriers have several rate packages from which to choose, depending on the application. Wireless Links products support the following network architectures:
iDEN
iDEN is a wireless protocol invented by Motorola, used by Nextel and Southern Linc in the USA and Telus in Canada. iDEN is the only current network that supports fast (300ms) push-to-talk (Direct Connect) and full duplex cellular voice services. iDEN supports current always on TCP/IP based packet data services at speeds of 19.2 kbps. This protocol was the first always-on, always connected packet data service to be launched on a true national footprint basis, so it achieved higher initial penetration rates than any other carrier in terms of the service industry.
GPRS
GPRS is essentially generation 2.5 of the global standard GSM, which is supported by T-Mobile and AT&T in the United States and in Canada by Rogers. GPRS provides always-on / always-connected high speed packet data services at speeds up to 86 kbps, with typical connection speeds of 56 kbps. GSM third and fourth generation networks, called Edge and HSPDA are now being deployed by many GSM operators, with significant enhancements in data speed.
CDMA
The new generation of the global standard CDMA 1xRTT supports always-on / always-connected packet data at speeds up to 144 kbps. 1X is now offered by several major cellular carriers throughout North America, including Verizon, Sprint and the Canadian Mobility group of carriers, including Telus, Bell and several others.
