25Data connection types over the mobile phone network

Overview

Your iPAQ supports different types of 2G and 3G connection standards. The table below provides brief information about the connection standards supported by your iPAQ and the features each standard provides:

Connection Standard	Technology Generation	Supports Data	Supports Simultaneous
			Data and Voice
HSDPA	3.5G	Yes	Yes
WCDMA	3G	Yes	Yes
EDGE	2.75G	Yes	No
GPRS	2.5G	Yes	No
GSM	2G	No	No

HSDPA

High Speed Downlink Packet Access (HSDPA), also known as 3.5G, is an enhancement of Wideband Code Division Multiple Access (WCDMA) which is based on 3G technology, and offers faster data speeds. Your iPAQ supports HSDPA and 384 kbps uplink. iPAQ also supports WCDMA over three different frequency bands (850/1900/2100). When WCDMA or HSDPA is available, the iPAQ uses the technology and reverts back to GSM/GPRS/EDGE if WCDMA or HSDPA is unavailable.

GPRS/EDGE

The GPRS/EDGE technology enables the mobile phone network to be used for messaging, to access the corporate network, or the Internet.

NOTE: EDGE is an enhancement to GPRS technology and enables higher speed data connections than GPRS. This means faster phone multimedia capabilities such as sending and receiving text or multimedia messages, and sharing video clips. Check with your service provider to see if they support EDGE technology. If your service provider does not support the EDGE network, the iPAQ defaults to GPRS.
