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.
