Nokia 7710 manual Data connections, GSM data calls

General information

Dead spots and dropouts - Dead spots are areas where radio signals cannot be received. Dropouts occur when the smartphone user passes through an area where the radio signal is blocked or reduced by geographical features or large structures.

Signal impairment - Distance and obstacles can cause signals to become out-of-phase. They can also cause reflected signals. Both situations result in a loss of signal strength.

Low signal strength - Due to either distance or obstacles, the radio signal strength from a cell site may not be strong enough or stable enough to provide a reliable data connection for communication. Therefore, to ensure the best possible communication, remember the following points:

•The data connection works best when the smartphone is in a stationary position. Attempting wireless data communication while in a moving vehicle is not recommended.

•Do not place the smartphone on a metal surface.

•Check that the signal strength on the smartphone display is sufficient. Moving the smartphone within a room, especially towards a window, may result in a stronger signal. If a signal is not strong enough to support a voice call, data connection should not be attempted until you can find a location with better signal reception.

Data connections

GSM data calls

A GSM data call enables data transmission rates of up to

14.4Kbps. For availability and subscription to data services, contact your network operator or service provider.

High-speed data calls (High Speed Circuit Switched Data, HSCSD)

HSCSD enables data transmission rates of up to 43.2 Kbps, which is four times faster than standard data rates of the GSM network. HSCSD is comparable to the speed of many computer modems that communicate with fixed telephone networks.

For availability and subscription to high-speed data services, please contact your network operator or service provider.

Note: Sending data in HSCSD mode may drain the smartphone’s battery faster than normal voice or data calls, as the smartphone may send data more frequently to the network.
