Radar technology helps to speed up next generation broadband upgrade in Salisbury

The city is on schedule to be the first of 38 across the UK to see the completion of the roll-out of FTTP broadband.  

Using GPR allows Openreach’s engineers to see and map out a clear route for its new cables without any drilling, probing or digging.

It means they can avoid the need for disruptive road closures and minimise the risk of obstructing or damaging any existing infrastructure already buried underground.

The technology is being used to support another new engineering technique called micro ducting – one of a raft of innovations being employed to make Salisbury the first entire city in the country to gain access to the company’s ultrafast full fibre broadband.

Openreach’s chief engineer Andy Whale, said: “This is the first location in the UK where we’re aiming to upgrade an entire city network in a single year, so it’s a hugely ambitious project, but being able to use time and cost saving innovations like radar and micro ducting, combined with the unrivalled experience and skill of our engineering teams, means that we can have more confidence that it’s achievable.

“We’re constantly looking at ways of improving and evolving the build process, and these are just the latest additions to our innovations toolkit.

“Micro ducting allows our teams to install new cables much more quickly – up to 300 metres each day. The technique is also less disruptive for local residents, reducing the amount building work – road works and all the associated disruption - by about 50 per cent, and it also uses fewer resources so it helps to reduce our costs and build times.

“Using radar also makes the whole process safer. We’re digging into pavements that have other utilities like electricity, gas and water buried underneath. The last thing we want to do is cut off people’s supply by accidentally damaging a cable, so GPR means we can keep that risk to an absolute minimum.”

Following successful trials, Salisbury is the first location in the UK where Openreach is using the new building methods, with engineering teams connecting an initial 130 premises in Bemerton, in the western part of the city, over the coming weeks.

Whilst Openreach is typically reusing many of its existing poles and underground ducts to build the new network, the company believes micro-ducting could be a useful option when it comes to extending the network into areas that don’t have any existing infrastructure.

Openreach is aiming for its Fibre First build programme in Salisbury to be completed within a year, and it will deliver fibre optic broadband cables from the exchange directly to more than 20,000 premises across the city.

When the build is complete, families, businesses and public buildings across the city of Salisbury will be able to reap the benefits of fast, reliable and future-proof broadband for decades to come.

Openreach is working closely with partners across the city to make sure the infrastructure build can happen at an unrivalled pace and with minimal disruption to local residents.

With this close collaboration, and the expertise Openreach has accumulated over many years of fibre broadband delivery, the company hopes to have its new services ready to order throughout the city by April 2020.

Salisbury is one of 38 locations across the UK have now been included in the first phase of Openreach’s multi-million pound Fibre First programme.

More than 1.2 million homes and businesses across the country now have access to fast, more reliable and future-proof FTTP broadband services over the Openreach network, since the launch of the programme last year.

Openreach aims to reach four million homes and businesses with ‘full fibre’ broadband by the end of 2020, with an ambition is to reach 15 million premises by the mid-2020s, and ultimately, the majority of the UK, if the right conditions to invest are in place.
