Working with Wireless Wide Area Networking (WWAN)
Overview
The Dolphin 70e Black has two radio options for WWAN connectivity:
• a muli-mode WWAN radio, which provides support for three band UMTS/HSPA+ (3G) 850/1900/
2100 MHz, quad band GSM/GPRS/EDGE (2G/2.5G) 850/900/1800/1900 MHz, and dual band
EV-DO/CDMA 800/1900 Mhz, or
• a GSM WWAN radio, which provides support for two-band UMTS/HSPA+ (3G) 900/2100 Mhz
and quad-band GSM/GPRS/EDGE (2G/2.5G) 850/900/1800/1900 MHz.
Both radio options support voice and data communication.
Requirements
Using GSM/HSPA+/UMTS/GPRS/EDGE requires:
• a network subscription to a GSM/HSPA+/UMTS/GPRS/EDGE network (you need to know what service
providers are in your geographic area), and
• an installed SIM card that has been activated by the network service provider (see Installing a SIM Card
and/or Memory Card on page 3-15).
Using a CDMA requires:
• an active account with a CDMA carrier. The account is linked to the Mobile Equipment Identifier (MEID)
of the integrated WWAN radio.
Antenna Band
The WWAN radio features an internal antenna that is optimized for power output and receiver sensitivity.
This is an omni-directional antenna.
For terminals with the multi mode WWAN radio, there is a penta band antenna that supports 850, 1900,
2100 Mhz (UMTS/HSPA), 850/900/1800/1900 Mhz (GSM/GPRS/EDGE) and 800/1900 Mhz (EV-DO/
CDMA).
For terminals with the GSM only WWAN radio, there is a slightly different penta band antenna that
supports 900, 2100 Mhz (UMTS/HSPA) and 850/900/1800/1900 Mhz (GSM/GPRS/EDGE).
GSM Short for Global System for Mobile communications, GSM is an open, non-proprietary wireless
WAN system that is constantly evolving and growing.
HSPA+ Short for High-Speed Download Packet Access, HSPA+ is a non-voice value added service that
allows packet-switched data to be instantly sent and received across mobile telephone networks.

that allows packet-switched data to be instantly sent and received across mobile telephone
networks.
GPRS Short for General Packet Radio Service, GPRS is a non-voice value added service that allows
packet-switched data to be instantly sent and received across mobile telephone networks.
EDGE E-GPRS is a non-voice value added service that allows packet-switched data to be instantly sent
and received across mobile telephone networks at a higher data rate than standard GPRS.
CDMA Short for Code Division Multiple Access.
1xRTT Short for Single-Carrier Radio Transmission Technology.
EVDO Short for Evolution-Data Optimized.
