iMesh

Ideal for the provision of wireless connectivity in smart cities, iMesh provides open standard multipoint-to-multipoint wireless connections for roadside IP devices.

Product Overview

iMesh is a wireless router enabling multipoint-to-multipoint data communications. iMesh is used to provide reliable communications for traffic signal installations throughout the UK and is supported by all of the UK's leading traffic signal installation contractors.

Features and benefits

iMesh provides highly reliable, secure wireless connections between roadside assets.

iMesh is available in two enclosure formats as shown in Figure 2 below:

An external-grade router which can be powered by mains, dc or power-over-ethernet.

A cabinet-grade router where the iMesh electronics is installed in a roadside cabinet. This uses a passive antenna up the traffic signal pole. With this option there is no electronics up the pole which makes maintenance easier.

Internal and External-grade iMesh routers

iMesh is multipoint-to-multipoint which means multiple routes through a network are automatically established, thereby giving multiple redundant routes (where sightlines allow).

iMesh continuously measures the performance of all routes and uses an algorithm to transmit data using the most efficient route.

Each iMesh router supports up to three radio units which can be either 2.45GHz or 5.8GHz. Each radio unit can support up to four independent networks - each with its own IP address range and firewall. This means that different services can be allocated to separate networks (and human managers) without affecting each other.
