GPRS General packet radio service. GPRS
enables wireless access for mobile
phones to data networks (network
service). GPRS uses packet data
technology where information is sent in
short bursts of data over the mobile
network. The benefit of sending data in
packets is that the network is occupied
only when sending or receiving data. As
GPRS uses the network efficiently, it
allows for quick data connection setup
and fast data transmission speeds.
You must subscribe to the GPRS service.
For availability and subscription to
GPRS, contact your service provider.
During a voice call, you cannot establish
a GPRS connection, and any existing
GPRS connection is put on hold unless
the network supports dual transfer
mode.
GPS Global positioning system. GPS is a
worldwide radio navigation system.
HSDPA High-speed downlink packet access.
HSDPA brings high-speed data delivery
to 3G terminals, ensuring that users
requiring effective multimedia
capabilities benefit from data rates
previously unavailable because of
limitations in the radio access network.
HTTP Hypertext transfer protocol. A document
transfer protocol used in the web.

HTTPS HTTP over a secure connection.
IMAP4 Internet mail access protocol, version 4.
A protocol used for accessing your
remote mailbox.
Internet An access point is where your device
access point connects to a network. To use e-mail
and multimedia services or to connect
to the internet and browse web pages,
you must first define internet access
points for these services.
Infrastructur The infrastructure operating mode
e operating allows two kinds of communication:
mode wireless devices communicate with
each other through a wireless LAN
access point or wireless devices
communicate with a wired LAN device
through a wireless LAN access point. The
advantage of the infrastructure
operating mode is that you can have
more control over network connections
because they pass through an access
point. A wireless device can access the
services that are available in a regular
wired LAN: company database, e-mail,
the Internet, and other network
resources, for example.
