Tips for Successful Cellular
Operation
The following section lists several issues to be aware of when
using cellular channels for data communications:
G
If possible, avoid peak cellular transmission hours.
Heavy telephone traffic during this period (for example,
rush hour and lunch hour) can impair network conditions
and affect data transfers. Cellular rates are also lower
during off-peak hours.
G
When using a hand-held cellular telephone (a
600 milliwatt telephone), make sure the antenna is
extended and that the telephone rests in a vertical
position. Commercially available leather briefcases that
hold the computer and telephone help facilitate this.
G
When using a portable cellular telephone (a 3 watt
telephone), make sure that the telephone is attached to
an external antenna.
G
Cellular communications within a building may not be
possible due to the number of obstructions within a
building. If you are having problems while trying to
transfer or receive data from inside a building, try
locating the cellular telephone near a window for better
cellular reception.

Performance when stationary is usually better than when
moving. If you encounter problems, stop the vehicle and
place the call from a stationary position
