So it seems the race is on to build 4G networks now, which is good because everyone needs more bandwidth, right?

Wait a second... I have a Galaxy S3 and over my 3G connection, I can stream music, watch YouTube videos, tether to my laptop and Teamviewer to my office PC fullscreen with little to no lag. Where I have coverage, that is.

Remind me why I need 4G again?

Tell you what I would like though. Some coverage at Castlepoint, my favourite holiday spot. Among others.

If my mobile provider said "You have a choice: more coverage outside the cities, or 4G in the city, which would you prefer?" - I'd choose the coverage.

Are we investing in 4G because there's a need for it? Or just to keep up with overseas with their higher population density and less mountainous terrains?

Just a thought...

Think about the growth of 3G packet switch traffic over the last 12 months? Not too far off in the close future the spectrum and networks are going to start choking, spectrum is not finite

4G / LTE makes better use of the spectrum a carrier has to use, Mobile Coverage is not static either I can tell you now the coverage foot print today is going to change in the next 8 weeks and then the following 8 weeks again and so on ................

Many new RBI sites are 4G / LTE 700Mhz ready just waiting for the spectrum and devices

I remember being content with 2G data, and I suppose a lot of eftpos providers are still content with it and based on the 2G expansion tweets from JohnR every now and then, I'd say coverage is still growing. I think anticipation of future uses will create need for it, as it did with 3G. Phones updating in spec, 1080p screens that can cater to 1080p streams?

increasing coverage has huge diminsihing returns. getting the first 80% coverage probably costs about the same as getting the next 5%. Given telcos are up to 97% (population) getting a further 1-2% would just be hideously expensive.

Also, 4G isn't about the speed at all really (despite the adverts claiming it). It's really about spectrum efficiency. It means Telcos will be more able to cope better with the masively increasing demands for more data (not just per person, but more people actively using data)

s'pose... but am not entirely convinced. I'd have thought that urban wifi (such as Wellington's CBDFree) might be the answer. I use that on my iPad since it's a wi-fi only one.

I'd like some coverage in that 4km long train tunnel on the line from Porirua to Wellington too... wonder how easy it is to provide coverage in tunnels? I think there's repeaters in the Terrace tunnel so maybe it could be done

They are not repeaters in the terrace tunnel they are actual cellsite

There are a whole lot of smart power meters being installed that use GSM to call home, As us humans go to 3 and 4G the robots are taking over the old space.

Also to the OP, I think that Castlepoint in within RBI coverage, so why would VF install something short term until the RBI rollout gets there?

Simple answer

3G is inherently a circuit switched based technology with IP in many ways being a bolt on.

4G is a fully IP based.

Yes 3G may seem fine for data but it's a limited technology in mansy ways - packet loss due to HSPA+ hard handovers is one classic example. Speed isn't the key feature of 4G, it's all about capacity and capability.

It is not easy to put coverage into train tunnels. Apart from the equipment costs you also need to shut down the train network to do this as you can't just put in a detour while the work is done. You also have to deal with interference from the electric trains.

Also, compared to a tunnel like the Terrace tunnel there just aren't that many people passing through using their phones so it would be hard to justify the costs.

Does that mean that VOIP calls like Skype/SIP based one's over 4G will be crystal clear and there will be no loss in quality or calls will not drop during handovers from tower to tower when traveling providing you are always in 4G coverage?

Do whatever you want to do man.

Minor point here, but I would have thought that there would be more demand in railway corridors/tunnels than road corridors/tunnels. Most car journeys have no passengers, and the driver shouldn't be doing very much with their phone while driving (not watching youtube I'd hope!) whereas in a rail tunnel you have potentially hundreds of people (during peak times) who could be using their phone to watch videos, stream music or using 3G to do work on their laptop.

Still, I'm sure that if it was a viable idea then at least one network would have implemented it by now.

Building / expanding mobile networks costs real $$$ and they are not cheap to deploy and maintain and also permits would be required like building any cell

Agreed, if it was viable someone would have done it.

Don't forget though with a road tunnel you get a constant stream of people going through but with a rail tunnel it will be more like 8 trains per hour (4 in each direction).

I haven't been able to quickly find any info on traffic volumes through the Terrace tunnel.

Perhaps they put the coverage in for when people are stuck in a jam and they want to ring to say they are delayed :)

I would've said it was more to do with people dropping calls, handsfree of course, while going through the tunnel?

Because Cellphone Network Engineers have their own carparks, so don't take the trains?

With this mentality we would be in the stone age. We don't "need" anything.

I hope Vodafone will deploy DC LTE as soon as it is possible to advance tech.
