6. Sierra Wireless Products and CDPD
Sierra Wireless produces a number of devices and applications that work with CDPD, as well as
other wireless data technologies. For more information about any of the following items, visit the
Sierra Wireless Web site at www.sierrawireless.com
.
6.1. CDPD-Only and Multi-Mode Devices
An industry leader in wireless data connectivity, Sierra Wireless makes a wide range of devices
that support both CDPD and other technologies, including circuit-switched data communications
(CSC), wireline data connections, the Global Positioning System (GPS), telemetry, and legacy
protocols.
Other Sierra Wireless devices support only CDPD; for those for whom the single standard is
sufficient.
6.2. AirCard
®
PC Cards for Handhelds and Notebooks
Sierra Wireless AirCard 300 PC Card modems plug directly into industry-standard PC Card slots
in notebook and handheld computers. They allow easy wireless access to the Internet for any
supported portable computer in areas with CDPD coverage.
The AirCard 300 is a CDPD-only modem, available as two models: one that supports handheld
computers (such as Pocket PC devices with PC Card slots), and another that supports both
handhelds and notebooks.
The AirCard 350 extends the technology of the 300 with a more rugged antenna and support for
the AirBooster 350 3-watt RF amplifier, for areas with poor coverage (the two together are known
as the AirCombo 350). This modem is primarily intended for public safety and field service.
6.3. Wireless Telemetry Systems
The Dart 300, successor to the popular Dart 200, allows remote locations such as energy
distribution sites, water and waste water plants, material storage and distribution areas, traffic
signals, time clocks, and other fixed data systems to relay data through the CDPD network, and
thus not have to be connected to landline wires.
6.4. Mobile In-Vehicle Dispatch/Database Access
The MP200 series modems provide wireless access via CDPD, and also have an option for GPS
telemetry. They have high-power transmitters, and are very rugged modems for the harshest
environments.
Used by public safety and field service personnel, the MP200 series has also provided data for
real-time graphical displays of the positions of boats in the 2000 Americas Cup yacht race.
The MP210 is a multi-mode device, adding circuit-switched cellular (CSC) data capabilities to
their CDPD support.
