Arqiva Microwave Link Rollout

Case Study:
Expanding DAB radio services for all our enjoyment.


Project Overview:
Arqiva is a communications infrastructure and media services company operating at the heart of the broadcast, satellite and mobile communications markets. Arqiva provides much of the infrastructure behind television, radio, satellite and wireless communications in the UK, including Digital Audio Broadcast (DAB) radio services. As part of the expansion of DAB radio services, additional transmitter sites were required and the programme feed to these sites is provided by a network of microwave links. Merlin Wireless & Fibre Services provided full rollout services for the deployment of this network.

We carried out an initial Line of Sight (LoS) and tower survey to assess the feasibility of the proposed link. Once verified and the link (budget and frequency) has been planned a Pre-Installation Visit (PIV) was carried out to determine the specific requirements of each end of the link and from this we ordered all of the necessary equipment.  We designed and supplied the required interface steelwork, for example pole mounts and face frames.

The radio equipment was bench tested and pre-staged before shipment to site. Once on site, the field teams installed the racks, batteries, rectifiers and indoor radio equipment at ground level; and the antennas and baseband cables at height on the tower. The link was then commissioned and made ready to carry live network traffic, handover documentation completed and handed over to Arqiva network operations.

There was an initial programme of c.100 links across the whole of the UK.
