Wireless Communication
Your GD8000 supports up to four integrated radios for superior
wireless communication (One radio per category listed below).

Wireless Local Area Network (WLAN)

Wireless Wide Area Network (WWAN) with CRMA Express

Global Positioning System (GPS)

Wireless Personal Area Network (WPAN) Bluetooth
Since each customer’s radio configuration is unique, please
read the radio help installed on your desktop and refer to the
manufacturer documentation to setup and use your radio(s).
If you have the Radio ON/OFF option, slide the Radio ON/
OFF Switch to the left to power off all radio devices (airplane
mode).
CAUTION FAA regulations require that all transmit/receive
devices be turned off during flight. If you have radios in your
computer (including GPS) and your computer is equipped with
a Radio ON/OFF Switch, please use it to turn your radios off
during flight. If you have radios and you do not have a switch
to turn the radios off, either leave your computer off during
flight or contact your help desk for assistance.
WLAN radio option
Your computer may include an integrated Wireless Local Area
Network (WLAN) capability. See the radio help file on your
desktop for more information.
About WLAN
WLAN provides all the features and benefits of traditional
LAN technologies, such as Ethernet, without the limitations
of wires or cables. It enables mobility and flexibility without
compromising connectivity for today’s mobile user.
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.
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 All WWAN radios are capable of backward
