9.1.6.1 Usage Scenarios
The following usage patterns were used to determine the netpad battery life figures
quoted in Table 9.1 on page 171.
Warehouse:
Using a netpad with an 802.11b radio, the user performs five transactions per
minute, which includes a scan, a transmission to the host, a response from the
host and a screen update. The backlight is on for ten seconds/off for two
seconds for the duration of the shift. The user takes no breaks, and the unit is
always able to receive transmissions.
Meter Reading:
Using a netpad without a radio, the user performs one scan per minute, with the
backlight on for ten seconds/off for 50 seconds. User activity continues for 45
minutes, followed by a 15 minute break, during which the terminal would enter
Stand-By mode. There is no radio activity.
Field Service:
Using a netpad with a GSM radio, the user performs 12 transactions per minute,
where each transaction includes a scan, a transmission to the host, and an update
from the host. The terminal is used for 20 minutes, followed by 40 minutes in
Stand-By mode.
