OR/BT Microwave Towers


[link to this post]
 
Seeing how most ISPs seem to use the word Fibre in their non-FTTP offerings, just wondering whether telecommunication microwave towers still exist in an active sense in the UK and if so, do they carry any Internet traffic?

If so, perhaps some ISP's offerings should have microwave in their title? wink

Cheers!

There was microwave equipment pointing towards Ireland on Holyhead mountain. It has largely been removed.

yes, Openreach even uses microwave links to connect some of their cabinets to the fibre network

Some rural and many island exchanges are microwave backhauled to the rest of the network

The BT Tower has has most if not all of the microwave antennas removed. And as the tower is Grade II listed, planning permission was needed for the removal!

But yes there are still some microwave links around.

So should they sell that as µWTTC ?

I remember in the late 60s when I was 18, seeing a VHF telephone link from the Orkneys to the Scottish mainland. From the size of the array, somewhere between 50 to 100 MHz I would estimate.

Don't forget that the BT Tower, as it was, was a SECRET!

Then, just down the road from me, is the Capenhust Tower http://www.lamont.me.uk/capenhurst/original.html

Significant number of mobile phone transmitter sites (cell sites) are linked together by microwave connections.

Top picture on this page shows a new 5G street works pole with a small microwave dish on the left hand side just below the second set of antenna panels.

Indeed they are. However fewer are fed by microwave from BT exchanges, which used to be quite common. More common nowadays is to feed one mast with a 10Gb fibre, and then microwave from there to other ones. But increasingly it is necessary to use 10Gb fibre links rather than microwave, for capacity reasons.

I remember in the original 4G roll out (2012/2013) at the surprise that every cell site needed a 1Gbps connection. As usage / load has increased, many cell sites now transmit a lot more capacity on the radio side, so need sufficient back haul to the core network. 5G of course changes the calculations again in favour of 10Gbps. Good business for the physical network operators, (Openreach, Cityfibre, Vodafone etc).
