Working with Wireless Wide Area Networking (WWAN)

Overview

The 99EX has two options for WWAN connectivity, a data+voice GSM/HSPA+/UMTS/GPRS/EDGE radio or a data only Gobi radio, which supports GSM/HSPA+/UMTS/GPRS/EDGE and CDMA/1xRTT/EVDO.

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.

UMTS

Short for Universal Mobile Telecommunications System, UMTS is a non-voice value added service

 

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.

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 SIM Card Installation on page 9-3).

Using a CDMA requires:

•an active account with a CDMA carrier. The account is linked to the Mobile Equipement Identifier (MEID) of the integrated WWAN radio.

Penta Band Antenna

The WWAN radio features an internal antenna that is optimized for power output and receiver sensitivity. This is an omni-directional antenna.

For the WWAN radio, there is a unified penta band antenna that supports 850/900/1800/1900 (GSM/ GPRS/EDGE), 850/1900/2100 (HSPA+/UMTS), and 850/1900 (CDMA).
