Note: If you are using the
AirCard in a CE device, it is
recommended that you set the
Transmit Power Consumption to
low.

Transmit power consumption
The Transmit Power Consumption option allows you to choose
between maximizing your data transmission speed or
minimizing battery drain on your PC. The settings for this
option are:
•
Normal (Notebook)
•
Medium
•
Low (PDA)
Normal (Notebook)
If you select
certain network resources (if they are available) to maximize
the upload transmission speed. This increases peak battery
consumption slightly but unless you are using a CE device, the
increase has little effect. (The maximum possible data trans-
mission speed with this setting is 56 kbps).
Low (PDA)
If you select
, the AirCard makes no attempt to take
advantage of faster upload speeds that might be possible on
some networks. This minimizes peak battery consumption and
is the recommended setting for CE devices because they are
unable to meet the peak power demands of the AirCard while
operating at the highest upload transmission speeds. (The
maximum possible data transmission speed with this setting is
14.4 kbps).
Medium
The
setting has a maximum possible data transmission
speed of 28.8 kbps.
The change in data transmission speed or peak battery
consumption that results from changing these settings is
dependent on network conditions (such as the number of users
in your area), and in some circumstances, may not be
noticeable.
This setting does not affect the speed of downloads (data
transmissions from the network to the AirCard).
Frequency band and network
selection
Watcher has two options that affect your ability to obtain GPRS
service in any given area. You can select:
•
The frequency band you want to use
•
The network you want to use, if you are within the
coverage area of more than one network
