Introduction
The "em" series are the long range 868/915 radios (up to 16 km) using the mesh topology to
create network availability in areas where traditional networks are not available.$"
Completely certified, the mesh module allows, thanks to its very low consumption, to be
powered only by solar panels and therefore to be used even without supply of electrical
network."
They are designed for applications requiring small bandwidth, large number of sensors, ultra-
low power consumption, near-realtime control and monitoring and always available response
without any requirement for off-cycle."
The emMesh uses Microchip MRF89A chipset which is amplified up to 26db and with
reception sensitivity of up to -103 dbm allowing up to 16km distance between two line of sight
devices."
Secured, proprietary Mesh technologies uses fast FHSS patterns with payload encryption
allowing fast and reliable communications."
