Model A4MGK4A PCBA manual

General

The Model A4MGK4A Network Interface Card (NIC) printed circuit board assembly (PCBA) contains a frequency

hopping spread spectrum radio operating in the 902.4-927.6 MHz ISM frequency band plus a LTE Cat-M1

radio. It connects to the Alpha 4 (A4) electricity metering platform. When the A4MGK4A module is installed in

an A4 meter it can be used as a “gatekeeper” for mesh radio enabled meters. Installations of multiple mesh

radio meters comprise part of an Advanced Metering Infrastructure (AMI) system that utilizes a proprietary

network architecture and protocol devised by Honeywell.
