Working with Wireless Wide Area Networking (WWAN)
Overview
The Dolphin 70e Black has two radio options for WWAN voice and data communications:
• a multi-mode (software definable) WWAN radio, which provides support for three band 3.9G
UMTS/HSPA+ (850/1900/2100 MHz), quad band GSM/GPRS/EDGE (850/900/1800/1900
MHz), and dual band CDMA/EVDO Rev A - 1xRTT/EVDO (800/1900 Mhz) or
• a GSM WWAN radio, which provides support for two-band UMTS/HSPA+ (3.9G) 900/2100 Mhz
and quad-band GSM/GPRS/EDGE (850/900/1800/1900 MHz).
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 Replacing the Memory Card on page 3-17).
Using 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 two internal antennas: an omni-directional antenna optimized for power
output and receiver sensitivity and a second diversity receiver antenna.
