FLI supplied and installed the towers and
monopoles of the UK’s GSM-r network and
are now a part of future networks development.
Building and installing the GSM-r Network.
The Global System for Mobile Communications-railway (GSM-r) project ensures digital, secure and dependable communications between train drivers and signallers. Delivering significant benefits across the industry and helping to reduce delays, the GSM-r System increases safety, improves performance and provides better passenger experiences throughout Britain's rail network.
FLI supplied over 2500 towers and monopoles for the GSM-r project. There were many variations in height and design to suit locations and access restrictions, so FLI designed modular flexible ranges. This enabled us to deliver a tower at short notice and create bespoke solutions from standard items. We applied the same principles to our rapid deployment foundations, which were screwpiles and steel grillages. These could be installed in a couple of shifts, which is so much quicker and less disruptive than pouring concrete and has a much lower carbon footprint.
Monopoles and Lattice Towers
With engineering expertise from a 70 year history in telecoms markets, FLI own a catalogue of off the shelf tower and monopole designs, which in addition to GSM-r, represent the largest proportion of the UK’s mobile phone network.
Rapid Deployment Repeater Post
Hinged posts mounted on our Kentlidge foundations have been used for WiFi antenna and repeater sites across the GSM-r network. This combined structure and foundation offers an extremely fast and low cost installation. Only Green Zone working is required and with minimal ground intrusion, as no plant is needed. Crucially, all components including the Kentlidge foundation are hand carryable. The hinged posts have 5m and 8m height options.
5G mobile phone networks with higher loadings are in the pipeline for FLI and we are engaged in developing new structures and solutions for a technology that will play a part in rail telecommunication systems in the near future.
