AirCard 800 Series Installation Guide
The AirCard modem connection provides access to the
Internet. Once the connection is established, you can open your
browser and connect to any web site available on the Internet,
or access other Internet services (such as e-mail).
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 (kilobits
per second)
•
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 (Megabits per second) 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 modem uses
the fastest available service. If, for example, you are using an
AirCard modem in an area that has GPRS and EDGE service
but not UMTS or HSDPA service, the AirCard modem
connects using EDGE service.
Once the connection is established, you have access to all
Internet services.
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
