The following paragraphs discuss the API for power management of the

NORAND WAN implementation for the PEN*KEY HHC.
Power management for radio transmitters involves interactions among powerĆ

aware/unaware applications, the APM, and the radio hardware.
The following topics are discussed in this subdivision.

WAN Power Management Implementation

"

Installing the WANPOWER TSR

Some radios do some of their own power management, some do not.  Applications

developed at Intermec Technologies Corporation are radioĆpowerĆaware.  As for

applications developed elsewhere, some are aware of the radio's power manageĆ

ment facilities and some have no knowledge of the radio's power features.  Some

applications respond to Norand APM messages, some do not.
The NORAND WAN Power Management software provides a platform on which

all applications work and most applications can, to some extent, benefit from

power management.  As a minimum, WAN Power Management prevents those

power losses that result in data losses.
On the PEN*KEY HHC, the WAN is implemented as a serial port.  Applications

using this interface may be either powerĆaware or powerĆunaware.  PowerĆaware

applications use the WAN Power API to describe the required level of power

management.
