This guide is to aid more rapid development of embedded applications using the Pinnacle
TM
100 modem using the Hosted-
Mode firmware. This guide will describe the setup and operation of eDRX and PSM, as well as, providing current
measurements of the modem, for both LTE Cat-M1 and Cat-NB1 with the use of a R&S CMW500 and a Amarisoft Callbox
mini.
•
PSM is intended for applications that seldom send data (once a day, for instance), and does not need to be reachable
or reachable with long latency (several hours, for instance).
•
eDRX is intended for applications that need to be reachable but tolerate latency in an order of magnitude of 10
seconds or more.

The AirPrime HL7800 provides advanced and efficient low power modes in addition to 3GPP advanced power saving features
like PSM (Power Saving Mode) and eDRX (extended DRX).
This document provides a detailed description of the AirPrime
HL7800’s low power modes while it is configured in PSM or
eDRX.
