CRMA Express WWAN (option)

If you ordered the CRMA Express module option, your
computer may support one or more of these Wireless Wide
Area Network (WWAN) radios:

HSPA

High-Speed Packet Access (HSPA) combines High-Speed
Download Packet Access (HSDPA) and High- Speed Uplaod
Packet Access (HSUPA). It is a 3G GSM Mobile protocol in
the HSPA family, which provides a roadmap for UMTS-based
networks to increase their data transfer speeds and capacity.
Radio ON/
HSDPA deployments/cards/modules can support 1.8 Mbps,
3.6 Mbps, 7.2 Mbps and 14.4 Mbps in downlink mode and 2.0
Mbps and 5.6Mbps in the uplink mode.

EDGE/GPRS/GSM Network

The Enhanced Data Rates for Global Evolution (EDGE) network
allows users to transfer data with download speeds up to
200Kbps (70-130 Kbps typical). It is more than three times the
speed of GPRS. The EDGE network can help you perform at
higher levels of productivity by providing real-time wireless
access to critical business systems and applications.

UMTS/GPRS/GSM Network

Universal Mobile Telecommunications System (UMTS) - also
referred to as wideband code division multiple access (W–
CDMA), is one of the most significant advances in the evolution
of telecommunications into 3G networks.
UMTS is a worldwide standard for wide-area wireless
data communication based on Global Systems for Mobile
communications (GSM™). UMTS provides broadband mobile
access to business systems and applications that can help
improve mobile users' productivity.
UMTS provides broadband speeds with download speeds up
to 2Mbps (220-320 Kbps typical). It delivers four-to-six times
the speed of dial-up Internet access and eight times the speed
of GPRS wireless data service. UMTS allows mobile users to
respond to urgent email and access the Internet.

EV-DO Rev A - EV-DO Rev 0/1xRTT/CDMA

CRMA Express is upgradeable and when WWAN radio
technology changes, you can change with it. You can upgrade
your radio to the various supported CRMA Express modules
through General Dynamics Itronix service centers, giving you
greater wireless access when you need it. After initialization
the first time the unit is booted, refer to the radio help found on
your desktop for information about setting up and using your
radio.
NOTE
compatibility to support slower technologies when necessary
to provide the greatest possible coverage to the user.
