Battery Configuration; Smart Power Management Implementation - Motorola WA9901 Integrator Manual

Battery Configuration

The option to configure battery life/performance is available from version 1.0.40535 of the Workabout Pro4
software.
The configure performance option is used to manage battery life of the Workabout Pro4. There are five different
preconfigured settings to balance between read-performance and battery life. Battery life will be maximum when
the slider bar is kept to the left-most. The device will perform at maximum performance efficiency when the slider
bar is kept to the right-most. By default, the slider bar is set at the center.
All settings made using this option can be overwritten using RFID3 API configuration settings.

Smart Power Management Implementation

A smart power management algorithm (SPM) was also developed on top of the battery configuration. The main
purpose of this algorithm is to optimize the trade-off between battery life and performances to offer the best RFID
performances handled by WAP4 platform in real time.
This SPM algorithm will define the maximum RFID output power usable by WAP4 depending on following
parameters:
•
Battery depletion level
•
Battery temperature
•
WWAN
IMPORTANT
Scanner power impact is not detailed in this section as it is not recommended to trig both the
scanner and RFID simultaneously. This operation is prevented at the OS level and users
should not bypass this restriction.
