Overcapacity or Capacity Crunch?

A Qualcomm presentation from not too long back:

How to meet data demand?

And another report from the UMTS Forum that is suggesting that the data traffic will grow 67 times from 2010 to 2020, summary embedded below:

Summary of report: Mobile traffic forecasts 2010-2020

Then I came across this interesting discussion on Twitter and a blog post by Dean Bubley in Disruptive Wireless blog.

Overcapacity has been summarised in few words as: Overcooked forecasts + WiFi offload + optimisation + LTE + more spectrum + caps/tiers + well-designed apps

In the blog post Dean's mentioned about the falling data usage that has been reported by O2. I would strongly recommend reading it.

From the network point of view, I think overcapacity is better for the time being as we are prepared for the short term future. In the long run, new devices and innovative apps may suddenly start driving up the data demand again and hopefully by that time we have sorted out some more of the capacity crunch issues.

What do you think?

Another concept phone from Nokia called 'HumanForm'

Description as follows:

HumanForm was created in a joint effort between Nokia Design and Nokia Research Center to translate the most promising new nanotechnologies into meaningful user experience, prototype those for decision making; and transfer and set aspiration for future portfolio.

Project is a key to bring significant user experience benefits to the market thereby creating mindshare and value share through nanotechnology enabled experiences.

HumanForm is a visionary solution for a dynamically flexible device beyond touch screen and voice communication where technology is invisible and intuition takes over. Natural interactions are enabled with kinetic user interface.

HumanForm concept and a follow-up Nokia Kinetic Device prototype were launched in Nokia World 2011.

2nd Workshop by 3GPP and Broadband Forum

3GPP and Broadband Forum held another joint session recently. Here is the summary from that event (3BF-11046.zip)

All presentations and documents from that event is available to download and view here.

Video on the Vision of the Future

I came across couple of videos recently on how User Interface for the future is going to be different than what we are used to. Its already getting changed as we get used to the touch screens and gesture recognition. Here is the first video that came out couple of weeks back and has already had over 2 million hits:

There is a whole blog post dedicated to this which you may be interested in, available here.

Another one is on the gesture recognition that will probably make big on the future devices including TVs.

On a lighter note, the future generation would probably just take the touch and gesture recognition for granted. Here is one such video:

Redirection, Reselection, Handovers and other Inter-RAT combinations in LTE

Another one from Qualcomm's 4G World presentation. You can see the number of scenarios that would have to be taken into account for; this was one of the reasons I believed SVLTE may be a good choice.

Devices may require support for over 40 RF Bands to be used universally

Interesting picture from Qualcomm presentation in 4G World that shows that for Universal use, a device may have to support over 40 RF bands (which may not be physically possible and may also be overly expensive)

Ericsson Video: Networked Society 'On the Brink'

In On The Brink we discuss the past, present and future of connectivity with a mix of people including David Rowan, chief editor of Wired UK; Caterina Fake, founder of Flickr; and Eric Wahlforss, the co-founder of Soundcloud. Each of the interviewees discusses the emerging opportunities being enabled by technology as we enter the Networked Society. Concepts such as borderless opportunities and creativity, new open business models, and today's 'dumb society' are brought up and discussed.

Three quick 3GPP Videos

Balazs Bertenyi, Dealing with the data explosion: Speaking about how 3GPP manages Releases and giving details of some of the key LTE features and some new work on the horizon.

Andrew Howell, GERAN and LTE Interworking: Andrew Howell, 3GPP GERAN Chairman, gives some background on the work of the GSM/EDGE RAN groups, including GELTE and the impact of machine type communications over legacy networks in the LTE age.
