SGP+M is a system developed by Landis+Gyr and running in Brazil (and potentially other countries), it stands for Sistema de Gestão de Perdas e Medição (System for Management of Losses and Metering). It is divided into Primary Concentrators (Concentrador Primário or CP) and Secondary Concentrators (Concentrador Secundário or CS).

Note that I don't access to the hardware described here. All of my research was done through observation and research.

* Rio de Janeiro, Brazil

== Metering Module ==
[[File:SGP+M Meter Module for Secondary Concentrator.png|thumb|Metering Module]]
The Metering Module (Módulo de Medição) is installed inside the CS, each utility client has one dedicated to them (or 2/3 if they have a two-phase or three-phase system).

This module has a built-in smart meter system, contactor for remote shutdown, and a phototransmitter and photoreceiver for communication with the CS computer.

== Secondary Concentrator ==
[[File:SGP+M Secondary Concentrator.png|thumb|Secondary Concentrator]]
The secondary Concentrator houses 12 Metering Modules, a CPU/Radio (metal box on the right) and a main MCCB. The Metering Modules talk with the CPU through a shared optical interface. The CPU contains the software/harwdare to communicate with each meter and a built in radio that communicates with the Primary Concentrator through some proprietary FHSS stuff briefly mentioned in the manual.

 The PC holds inside a computer that I assume is way stronger, a radio to communicate with all the SCs around and a GPRS radio to inform power usage data to the power company.
