GSM data transmission
The Nokia 9210 Communicator employs the data transmission capabilities of the
GSM network to send faxes, short messages, and e-mail, and to establish
connections with remote computers.
Wireless data connections can be made from most locations where your phone
operates. However, it is recommended that you move the communicator to a
location where the strongest possible wireless signal can be obtained. When the
signal is strong, data transmission is efficient. In general, you should not expect the
same performance from wireless data communications as from landline
communications, due to the inherent characteristics of the wireless environment.
The following factors may impair wireless connections:
Noise
Radio interference from electronic appliances and equipment, as well as from other
phones will affect the quality of wireless data transmission.
Cell handover
As the phone user moves from one network cell to another, the signal strength of
the channel drops and the wireless telephone exchange may handover the user to
a different cell and frequency, where the signal is stronger. A cell handover may also
occur when the user is stationary, due to varying wireless traffic loads. Such
handovers may cause slight delays in the transmission.
Electrostatic discharge
A discharge of static electricity from a finger or a conductor may cause erroneous
functions in electric devices. The discharge may result in distorted display and
unstable software operation. Wireless connections may become unreliable, data
may become corrupted, and the transmission halted. In this case you need to end
the existing call (if any), close the cover and switch off the phone (if on) and remove
the battery. Then replace the battery and establish a new wireless connection.
Dead spots and dropouts
Dead spots are areas where radio signals cannot be received. Dropouts occur when
the phone user passes through an area where the radio signal is blocked or reduced
by geographical features or large structures.
