G2XL-Generation 2 eXreame Long Range Wireless Module
Product Manual

Technical Overview

General Description

Monnit G2XL delivers transformative RF performance
in a compact, nano-power module capable of
delivering a 50+ mile range (LOS) performance while
consuming 1.0uA between transmissions. Monnit has
integrated this module with various sensor types to
provide a long range wireless sensing solution.

Additionally, the module supports flexible transmit
power options, data rate manipulation, over-the-air
upgradeability, data logging, robust link-level security
encryption, and over 20 embedded digital and analog
peripherals for end-application utilization.

Monnit integrates these modules into gateway and
sensor products for both OEM and direct customers.
Monnit’s solutions target enterprise customers,
enabling them to obtain the benefits of the IOT
revolution and reach all corners of the globe.

Principle of Operation

The module contains three different operation profiles
to facilitate data links: PEER, BSN, and EDN.
Additionally, the module can be loaded with standard
application firmware with a UART AT interface or a
more sophisticated API mode.

PEER devices are used to facilitate point to point
streaming of information from one device to another.

BSN or EDN modes create point to multi-point ultra­low power networking topology for sensors and
gateways.

RF,Power,and Data Interfaces

RF Connectors

The module supports up to two U.FL/APEX connectors. The end-customer must connect an antenna to
all antenna ports used in a customer’s application. Using an antenna port without a 50 ohm termination
constitutes misuse and may cause damage to module. Special care must be taken to ensure this situation does
not occur.

Power Warning

Hardware cannot withstand negative voltage. Please take care when connecting power to module.
