LTE will be known as 4G!


I have been mentioning since 3 years that LTE is 3.9G and its not 4G. In fact I have brought it up in many posts and discussions so that we do not dilute the term 4G. From my recent visit to the LTE World Summit and from the news, etc. it seems that the marketing guys won and LTE would be known as 4G.
In the picture above you can clearly see that the press releases by well known companies as well as Samsung's dongle has 4G for LTE stamped. It may be very difficult to reverse this '4G' means LTE term.
So I have now started thinking about what LTE-Advanced will be known as. Here is my attempt:
  • 5G - Not sure if people will buy this. Assuming that LTE-Advanced specs are ready by March 2011 (as is predicted) then people wont be ready to jump from 4G to 5G this soon.
  • 4G+ - Not sure if this sounds sexy enough
  • Super 4G - Boring
  • Turbo 4G - reminds me of F1
Suggestions welcome.

Police call for remote button to stop cars

From The Guardian:

British Police are urging Ministers to give them the power to stop vehicles by remote control.

In what will be seen as yet another example of the in-creasing power of Big Brother, drivers face the prospect of their cars being halted by somebody pushing a button.

The police lobby is being led by Superintendent Jim Hammond of Sussex police, who chairs an Association of Chief Police Officers technology working group which is examining the idea.

'Providing an effective means to remotely stop a vehicle is fast becoming a priority,' Hammond told a European conference. 'The development of a safe and controlled system to enable remote stopping has the potential to directly save lives.'

However, Bert Morris, deputy director of the AA Motoring Trust said: 'People don't like the idea of Big Brother taking over their driving. In years to come that might be acceptable, but it's very, very important that there's a step-by-step approach.'

Cars could be stopped by the gradual reduction of engine power so it slowly comes to a stop, or by making sure when drivers come to a halt they can not move again.

Stopping cars remotely sounds futuristic, but the basic technology is already available and used in lorries to limit the top speed to 56mph and in new systems to immobilise stolen cars.

The key is the electronics box in most new cars which, when the driver presses the accelerator or brake, sends a message to the engine to speed up or slow down. It can be programmed to limit the speed generally or according to the position of the car, established via a GPS satellite. For remote operation, a modem, which works like a mobile phone, can be used tell the car to slow down or stop.

Similar radio telemetry was used by Formula One pit crews to adjust the engines of racing cars at up to 200mph - until it was banned this year.

'The technology exists and will become more refined as time goes on,' said Nick Rendell, managing director of the Siemens business developing this technology in the UK.

A senior police officer - assumed to be the chief constable or deputy - can already give the order to stop a car remotely, but that power has rarely if ever been used, said Morris. To use any new powers more widely, police must first overcome some practical problems to reassure Ministers that vehicles would be stopped safety. Ministers will also want reassurances that drivers would not be mistakenly stopped.

ACPO insists that it would only introduce the technology when it was safe. It is calling on the Government to introduce the legislation which it says will be vital to stop vehicles when - as expected - manufacturers develop tyres that run when they are flat. This will make 'stingers' - the spiked strips thrown in front of speeding cars - useless to stop stolen and get-away cars or dangerous drivers.

It is also linked to pressure to make cars 'pointless to steal' because of growing concern about more violent car crime as vehicles become harder to take. The RAC Foundation recently found there were as many as 1,200 car jackings in Britain last year.

Another link is to technology which would stop cars going above certain speed limits - either a fixed maximum such as 70mph, or varying according to the local limit.

The system could even be programmed to reduce speeds below the limit in bad weather or when school children were expected to be about, said Robert Gifford, director of the Parliamentary Advisory Committee on Transport Safety, which believes the technology could cut the 3,420 deaths a year on Britain's roads by 59 per cent.

Experts now believe the technology could start to be used voluntarily by the end of the decade and ultimately could be made mandatory.

Small cells and Wireless Capacity Growth

Self explanatory slide showing the impact of Small cells on the capacity growth. This is probably the best way to further increase the capacity.

Quality of Service (QoS) and Deep Packet Inspection (DPI)

One of the things I mentioned in my presentation in the LTE World Summit was that differentiation of Services based on Quality of Services is required to be able to charge the users more.
This QoS can be varied based on deep inspection of the packets which can tell the operator as to what service a particular packet belongs to. The operators can thus give higher priority to the services and applications that are recommended by them and also block certain services that can be deemed as illegal or unproductive (like file sharing or P2P).

Continuous Computing claims to be one of the market leaders in producing the DPI systems. You can read this article by Mike Coward who is the CTO and Co-founder of Continuous computing here.

There is also this very interesting paper on QoS control in 3GPP EPS which is available freely here.

Please feel free to comment or suggest how do you see DPI being used in the future.

Interesting calculation showing that data cost to operator is €1/per GB


The 'Cost per Bit' issue...

Cost per bit has always been an issue from operator point of view. The other day an operator tried to show a comparison of data transfer with SMS. Though this may make some of us feel guilty that we are ripping these poor operators off ;) in reality most of us agree that it is the other way round.

A slightly older report from Ericsson suggested that from operator point of view, 1GB data transfer can cost as low as 1 euro.

So if we now plug in the above information into the slide below, presented by Moray Rumney of Agilent in the LTE World Summit, we can see that the operators have been earning massive profits on our behalf.



With Mobile broadband becoming more common and cheaper, users may not be willing to pay any more than they are now. At the same time, they may expect the speeds to keep increasing at regular intervals. The operators will soon be forced (if not already doing so) to offer QoS based packages which can help them boost their revenue and provide better QoE to the higher paying users.

I will cover this issue of QoS, QoE and DPI in the upcoming posts.

If you are wondering along the lines of how to reduce this cost per bit then I would recommend you to go back and have a look at this discussion on Martin Sauter's blog.
If you are thinking along the lines of increasing ARPU with LTE, then please see my presentation here.

50 Billion Connected Devices by 2020 (2025?)

Back in April, Hans Vestberg, CEO and the President of Ericsson declared that there will be 50 Billion connected devices by 2020.

In the recently concluded LTE World Summit, this statement seemed to have gained lots of attention. Everyone quoted this left, right and center. The interesting thing was that some said that this would happen by 2025 and some also said 2030.

While we can make a generic statement that there will be some 50 Billion connected devices sometime between 2020 and 2030, not everyone was sure how they would be connected.

My understanding is that a device is connected if it has a valid IP (IPv6) address. That means that the PC's at home are included and anything connected over WiFi are included as well.

So by this definition, it wont surprise me if we probably have 100 Billion connected devices by 2030.

Redefining the wireless Quality of Experience (QoE) with LTE

Ken Wirth, President 4G/LTE Networks of Alcatel-Lucent showed us the following video in the LTE World Summit 2010. Its been available on Youtube for quite some time but I missed it before:

Using LTE to boost ARPU

Here is my presentation from the LTE World Summit 2010. The presentation was prepared for discussion during the Breakfast briefing on the 19th May 2010.
