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.

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

the corporate network, or the Internet.

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.
