If there's one thing being talked about a lot over the last year or so, it's 5G. It's a new technology for mobile broadband.

5G is interesting to large public broadcasters, because, I think, it's the only platform that can deliver everything that they produce: radio, TV and online; both live and on-demand. So, for a public service broadcaster, it's an important thing to be experimenting with.

But what's the deal with 5G?

At its heart, it's a fast internet connection that can replace 3G and 4G for mobile phones, but it has much higher capacity and could also, potentially, replace broadband connections at home as well.

It has one thing in it that could potentially be useful for broadcasters: 5G Broadcast. If you have a thousand people listening to your live radio station online, that normally means a thousand connections to your streaming server, and a thousand sets of audio data being sent over the internet. With 5G Broadcast, it means just one: because it uses broadcast technology to get your signal to your audience. That makes it more resilient, and better for the network.

It's been 40 years since Trevor Horn wrote the Buggles' "Video Killed The Radio Star." Video didn't, of course. 9 out of 10 people listen to the radio every week, in countries as diverse as Malaysia, the U.S., France and Australia. Radio's reach hasn't changed in the ...

Something called BBC Notes was posted on the BBC's Research and Development blog the other week. It's a web app "that shows text, images, and links, to enhance the listening experience during live events, live broadcasts, and on demand". There are quite a lot of these ...

As Google knows, I'm in Kuala Lumpur today, in Malaysia. Google knows exactly where I am. It knows where I was yesterday; what airline I used to travel here; what news stories I read this morning; what's in my diary for tomorrow. It knows what music I listen to, what ...

Recently, I was at Podcast Movement in Orlando. It's the largest podcast event in the world, I think, with a variety of sessions covering almost everything you needed to know about podcasting. The event grows each year. Podcasting is an increasingly serious business, ...

I don't much like talking about radio in negative terms. And I'd rather people didn't compare radio, a medium I love, with a cockroach, an insect I hate. Some cockroaches can live for a month without food, or even survive just using the glue from a postage stamp. And ...

RAJARCLICK TO ENLARGE RAJAR, the audio research company best known for the radio figures in the UK, also releases a survey called MIDAS every quarter; and it's always a good read. Some pieces of data are the same every quarter, but they seem to put new bits of data in ...

In an idle chat a few weeks ago on Twitter, I asked to see music logs from radio stations. (By a "music log", I mean the thing that is printed out for disc jockeys that tells you what songs you're playing that hour, and where the ad breaks go). I found one from 1996. ...

The radio ratings in Australia come out every six weeks, which I still find slightly amazing. I'm much more used to the UK's sedate pace of a set of figures every quarter. The local TV news bulletins report on the figures, too - something fairly unheard of in the UK. ...

Johannesburg, South Africa, is a place like no other to hold a radio conference, and I was privileged to be at Radio Days Africa recently on their tenth anniversary. Radio is an important part of life in Africa in general. Radio reaches people who cannot read or write; ...
