Facts about cellular data transmission

The Nokia 9000i Communicator employs the dig-

ital data transmission capabilities of the digital

cellular network to send faxes, short messages,

mail and to establish connections with remote

computers.

Cellular data connections can be made from

most locations where your mobile phone oper-

ates. However, it is recommended that you move

the communicator to a location where the

strongest possible cellular signal can be ob-

tained. When the signal is strong, data transmis-

sion is efficient. In general, you should not

expect the same performance from cellular data

communications as from landline communica-

tions due to the inherent characteristics of the

cellular environment.

The following factors may impair cellular con-

nections:

Noise

Radio interference from electronic appliances

and equipment, as well as from other mobile

phones in metropolitan areas where mobile

telephones are prevalent.

Handover

As the mobile phone user moves from one

network cell to another, the signal strength of

the channel drops and the cellular telephone

exchange may hand the user over to a differ-

ent cell and frequency, where the signal is

stronger. A cell handover may also occur

when the user is stationary due to varying

cellular traffic loads. Such handovers may

cause slight delays.

Electrostatic discharge (ESD)

A discharge of static electricity from a finger

or a conductor may cause erroneous func-

tions in electric devices. The discharge can re-

sult in “garbled” display and unstable

software operation. Cellular connections may

become unreliable, data may be corrupted,

and the transmission halted. In this case you

need to end the existing call (if any), switch

off the phone interface (if on) and remove the

battery. Then replace the battery and estab-

lish a new cellular connection.

Dead spots and dropouts

Dead spots are areas where radio signals can-

not be received. Dropouts occur when the

mobile phone user passes through an area

where the radio signal is blocked or reduced

by geographic or structural obstructions.

Signal impairment

Distance and obstacles can cause out-of-

phase reflected signals that 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 cellular connection for communica-

tion. Therefore, to ensure the best possible

communication, remember to consider the

following points:

• The data connection works best when the

communicator is in a stationary position.

Attempting cellular communication while in

a moving vehicle is not recommended. Fax

transmission is more easily impaired than

data or short message transmission.

• Do not place the communicator on a metal

surface.

• Check that the cellular signal strength on the

communicator displays is sufficient (see

chapter 2 "Getting started: Communicator

applications - Using the applications" on

page 2-8 and chapter 13 "Phone interface:

Display indicators" on page 13-2). Moving the

communicator within a room especially

towards a window, may result in a stronger

signal. If the cellular signals are not strong

enough to support a voice call, data

connection should not be attempted until you

can find a location with better signal

reception.
