GD8000 User Guide 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 compatibility to support slower technologies when necessary to provide the greatest possible coverage to the user. General Dynamics Itronix | 72-0137-003
