HSDPA, UMTS, EDGE, and GPRS service
support
GPRS, EDGE, UMTS, and HSDPA are add-on data services to
GSM mobile phone networks. The maximum data speeds
when connected on these services are:
• GPRS (General Packet Radio Service)—56 kbps
• EDGE (Enhanced Data GSM Environment)—216 kbps
• UMTS (Universal Mobile Telecommunications System)—
384 kbps
• HSDPA (High Speed Download Packet Access)—up to
1.8 Mbps on the downlink (receive) with 500 to 800 kbps
typical
GPRS and EDGE are 2G (second generation) data services.
UMTS and HSDPA are 3G (third generation) data services.
When establishing a connection, your AirCard uses the fastest
available service. If, for example, you are using an AirCard in
an area that has GPRS and EDGE service but not UMTS or
HSDPA service, the AirCard connects using EDGE service.
These data connections are Internet connections. Once the
connection is established, you can connect to any web site
accessible through the Internet or use Internet services (such as
e-mail).
Frequency band support
Every GSM network operates on one of these radio frequency
bands, in providing 2G (GPRS or EDGE) service:
• 850 MHz band—(also called the cellular band) used by
some North American service providers
• 900 MHz band—used by some European service
providers
• 1800 MHz band—used by some European and Asian
service providers
• 1900 MHz band—(also called the PCS band) used by
many North American service providers
Every network that offers 3G UMTS/HSDPA service does so
on one of these bands:
• WCDMA 850—used by North American service providers
• WCDMA 1900—used by North American service
providers
• WCDMA 2100—used by European, Asian, and Australian
service providers
