Multicast reduces the overhead too, as well as an LTE enhancement in the later versions that supports non duplication of data streams I think. It could become the standard listening method in years to come. I see DAB and older technologies as redundant in the long-term as they are very wasteful of spectrum and they need whole networks of masts just to steam digital MP2 audio streams only.
Somebody will bring up the free at the point of use question again, but there's nothing to stop development of a radio chip that works on IP data and where it is free to use because the broadcasters pay a (or multiple) network(s) to carry the permitted streams restricted and walled. We have already seen the likes of Amazon do deals with Vodafone for the Kindle that has a sim and permits access based on the Amazon to Vodafone contract, not the consumer. TomTom do the same with Vodafone. DAB transmitters aren't overly expensive because you don't need to run fibre or wired connectivity to them, it can all be done via satellite. |

I wouldn't say that DAB is particularly wasteful - unlike FM you get better efficiency because each transmitter in the network can use the same frequency (e.g. the BBC uses the same frequency nationwide for its DAB mux, whereas they occupy 10+MHz of FM), and if we moved to AAC+ that would improve audio quality and increase efficiency too. I don't think the VHF spectrum occupied by DAB is in any particular demand, unlike digital TV vs LTE
DAB transmitters aren't overly expensive because you don't need to run fibre or wired connectivity to them, it can all be done via satellite. It seems to me that using an existing IP data based multicast and LTE broadcast technologies could be more efficient and then the spectrum could be released. I'd love to see radios receive plain multicast IP data at some point. I don't know if 178-239 is any good for mobile use, but it could be released for other purposes and we could use mobile spectrum to deliver any IP data service people want inc multicast radio. |

I had an O2 sim for a while as I need calls and for that, it's superior to EE/3 where I live at least and I thought they were ahead of VOD for 3G900. The truth is that even when you get a full 3G signal like in Newton Abbot, you would often just get no data at all. Nothing. Quite absurd.

I would! Invented 30 years ago, it uses hundreds and hundreds of transmitters kicking out transmissions of MP2 audio to deliver about 30 audio channels. 61Mhz of spectrum from 178Mhz to 239Mhz to deliver low quality single purpose audio!

I still don't get the point of a whole separate network of transmission just for DAB, when IP streams could carry any data you wanted including any IP multicast streams. I'm sure there are technically superior and more efficient ways of delivering the same thing.
I'll mention free at the point of use again before somebody pipes up with that one. Let me stress that we're only used to mobile being consumer charged because that is the way it has always been done, it doesn't mean multicast IP streams can't be funded by the broadcasters as open access with no consumer subscription required on the consumer receiver, and neither does it mean a copy of every stream for every listener as technologies built into LTE and IP Multicast mean you can de-duplicate live stream data and carry it once to each site and only if it is needed. We will have an LTE network of 30,000+ sites in a few years capable of widespread IP streaming of audio, and hopefully new internet radio devices on the market for in-car and home. |

Hmm while I can't think of anything DAB spectrum could be repurposed for I agree it is less efficient than a multicast distribution. But I certainly wouldn't call for a switchover of any sort in the next 15yrs. LTE broadcast is still being worked on and the cost of replacing FM and DAB radios with more power hungry 3G/4G devices would be very expensive and wasteful. That doesn't even touch the problems with net neutrality and some services being free and others paid for.
Digital terrestrial TV is looking at a 2030 switch off, and with satellite TV also going out of fashion broadband multicast distribution could be the replacement like YouViews internet channels, however every premises in the UK will need a good connection of at least 5mbps or so, something which should easily be possible by 2030 mind. |

This already happens when you buy a Tomtom and it gets traffic updates over Vodafone, paid for by Tomtom, the same with the Amazon Kindle, you'll see many more "internet of things" devices, hopefully including internet radios that use mobile networks to connect that aren't part of a consumer or end user mobile subscription that will make use of the extensive LTE deployments that will be much more widely rolled out over the next 2-3 years. |

I wouldn't say it isn't an issue, I'd say it were murky waters. T-Mobile USA currently doesn't count certain music streaming apps as part of a users data allowance and is currently being questioned on that.
If a radio company paid for its streams to be carried over a network for free for the consumer, but a competing radio companies streams were charged for and so were a competing companies video service, then not all data is being treated equally. I'd argue that with a satnav or ereader you are paying for internet access as a part of the initial purchase cost, but say you were to buy a smartphone which came with access to Global's radio stations for free but you had to pay per the MB for Bauer's I would hardly call that fair. |

Fair point, I hadn't thought of it that way. My main concern has always been that the user pays their internet access rate and can do what they want within their data quota, but I see the argument you put across.

Yes I share a similar stance with net neutrality, I don't really agree with the Tory's on blocking certain services possibly including encrypted messaging like WhatsApp. One thing I don't like about net neutrality is that I believe traffic management should be accepted, or companies like Three would never be able to offer unlimited data.
Anyway this is all a bit off topic isn't it

Apple and AT&T/O2 clearly thought they were on to a winner with this thing called tethering, and where O2 could charge you a separate tethering tariff on top of your standard tariff. I forget how much it was at first, but think it was about £9.99 or £19.99 a month extra - and I don't remember how much data you actually got either. If you think of the whole net neutrality thing then how does it affect tethering? Being made to pay extra for using data with some devices, or being limited in what you can do altogether. |

Personally, I don't think broadcast type technologies like we have at present won't meet its end come 2030 - it still has plenty of life left in it. TalkSport and 5Live still have the majority of their listeners accessing them via Medium Wave! There's also inherent limitations of mobile cell coverage in looking to cover certain areas off main A roads and motorways which can be served adequately by FM, AM or DAB but where mobile reception is spotty - terrain and population density is a big factor. No mobile operator I know off has broke through the 95% population coverage barrier here in NI yet, even for 2G. There's also the case as to wherever individual 4G cell sites can potentially handle hundreds, if not thousands, of continuous streams to handsets at the same time. While internet radio, whilst growing but still having a limited mass appeal, can be handled reasonably well with a small-ish amount of users per cell as it is right now, its demand of requiring near continuous streaming contrasts to where bursts of data is perfectly fine for many other tasks e.g. sat-navs, even if multicasting is properly set up.
While the future is being looked at in terms of IP multicast, there are a lot of hardware hurdles to overcome - if TV is to be delivered over IP via terrestrial means without DVB-T or S variants, then such a line to the premises will need a guaranteed uncontented speed. Ordinary ADSL speeds themselves even at 8Mbps for those close to the exchange will struggle to cut it if contention isn't addressed. Many homes over here are at distances from the exchanges that get <2Mbps download speeds over ADSL and FTTC isn't available even allowing for the generally extensive coverage it has in NI. In some areas a properly installed fixed-wireless network that isn't heavily congested and doesn't fall over every two days (I'm looking at one NI provider in particular) could provide some breathing space in the short-term, the only viable long-term solution is FTTH or FTTP where line distance is far less critical |

Until Apple came along and 'invented' tethering, you just used your data however you wanted. Connect your feature phone to a PC via Bluetooth or USB and off you go.

X-Series. Wasn't that the deal with a Slingbox and some other bits and bobs? I had pretty much forgotten about this!

I used to be on 3 PAYG with an AYCE data add on and tethering was no problem. Never got pulled up on it but only really used it when away from home. It was good.

I remember the days of Orange PAYG where only Facebook access was allowed for a certain price but the whole Internet was available anyway. I felt so guilty haha.

Three had a walled garden early on. Seemed daft to me, especially for a 3G network.
It took them a few years to change course |

Probably because the "killer app" for 3G was deemed to be that people would pay 50p/min for video calling. I think 3 also wanted you to buy ringtones, video, games and such from their own site rather than from a third party.

Yeah, video calling never really took off did it. Think I tried it about twice before the novelty wore off/my wallet had had enough.
Even though I had something like 50mins free of video calls a month with Vodafone when 3G was first launched with my old Nokia phone I think I made 2 and then the novelty wore off. I have not even really bothered with it nowadays either as it does not really add much as you know what the person you are speaking to looks like. Might be different for business etc though. |

Apple tried to do it again with FaceTime, which again I've only used about three times, mostly out of curiosity as opposed to actually needing to use it.

The professional video conferencing world prides itself on interoperability - a company with Tandberg/Cisco equipment can theoretically call a company with Polycom equipment without trouble |

I agree with the other comment that we need interoperability & standards. Apple lied when they launched Facetime and said it would become open. |
