Up until this week, the largest traffic flows across Janet were inbound from GÉANT and the major content providers towards our members and customers.  The […]

Wi-Fi 6E – the Wi-Fi refresh we all need?

As I write on February 3rd, OfCom has just launched a consultation around release of a block of 6GHz spectrum for wireless comms. It seems a good moment to talk about Wi-Fi 6E.   Before we start, let’s be clear what we’re talking about. Most of us are comfortable discussing the zoo of 802.11 standards, […]

Capturing Requirements for Jisc Frameworks

I’ve procured and administered a handful of procurement frameworks on Jisc’s behalf over the years, and a lot of the language and accepted practices of public procurement are familiar to me (drummed in by colleagues in our excellent procurement unit).

Designing our way out of a rats nest!

A few (5) words on the process of designing new access networks, aka regional aggregation networks (health warning: written by not-a-network-designer). It Takes A Long Time I could leave it there, but for the sake of clarity I’ll delve into some of the more interesting and relevant details. So, we have a contractual requirement to […]

Back from holiday, back to work

There’s nothing like a good holiday to escape, relax and rejuvenate. I was away for a couple of weeks recently (read this post on LinkedIn about how I kept in touch with all things Jisc and Janet), as were a lot of the rest of the access programme team. A lot of us have got […]
