#FWIC: OTT Stats, Facts and Figures

The 4th Future of Wireless International Conference (#FWIC) is 2 weeks away and the main theme of the conference is "The Reshaping of the Mobile Industry". In some of the recent conferences I have attended, OTT has been one of the main topic of discussion and a concern for the operators. The operators are at the top of the food chain, whatever affects them eventually affects the other players within the mobile industry. With this is mind, we have prepared a document that collects all the figures in one place to be used as a handy reference for quoting stats and figures.

You can also connect with the other attendees of the conference on Linkedin here.

Finally, here is my summary of the event from last year. I look forward to meeting all of you who will be attending this event.

Whitespace Spectrum Management Issues

BT has been conducting a "White Space" trial in Isle of Bute, UK. Initial report suggests that the results are not very impressive. The following is from ISP Review:

Early feedback from BT’s trial of ‘White Space‘ (IEEE 802.22) wireless broadband technology on the Isle of Bute suggests that the service, which delivers internet access by making use of the unused radio spectrum that exists between Digital TV channels, still has a lot of problems to overcome, not least in terms of its sporadic performance.

In theory the 802.22 specification suggests that download speeds of up to 22Mbps per channel (Megabits per second) could be possible and some UK trials claim to have reached around 16Mbps, which is incidentally a long way off the UK’s chosen definition for superfast broadband (24Mbps+).

But separate reports from both PC Pro and the BBC today found that the service, which is complicated to deliver due to the ever changing spectrum and the risk of causing interference to DTV services, could struggle to deliver its top speeds.

At present BT’s implementation claims to be offering speeds of up to 10Mbps per channel, which will soon be upgraded to 15Mbps, but this reduces down to a maximum of just 4Mbps when 6km away from the transmitter. New tests at various points on the Isle of Bute showed speeds varying between just 1.5Mbps and 6Mbps (the latter was recorded within sight of BT’s mast).
In fairness White Space solutions are designed to target the last 10% of the UK where the government has so far only committed to a minimum download speed of just 2Mbps for all (Universal Service Commitment), which is a very low target. In addition White Space tech appears to deliver strong upload speed that is, in some cases, symmetrical. That makes it good for video conferencing and other upload dependent tasks.



As Fierce Broadband Wireless suggests, the low speeds could also be due to pre-standard gear that will just improve as time goes on.

The main reason for using this shared whitespace spectrum is due to the fact that the total amount of spectrum is limited and we want to make use of every available free spectrum to increase capacity of the overloaded networks.

Michael Fitch from BT recently spoke in our Cambridge Wireless Small Cells SIG event. The slide from his presentations neatly lays out the vision for shared spectrum.

In theory, even though this looks simple, in practice managing the database is a challenge by itself. The embedded slides below (Page 17 onwards) show the problems and the complexity associated with the database.

Time will tell how efficient and practical using whitespaces is.

Vuforia™: Qualcomm's Augmented Reality (AR) Platform

As I mentioned yesterday, while some people think that Augmented Reality is losing its charm, Qualcomm certainly thinks that things are looking up for AR and it can only get better. They have branded their AR platform as Vuforia. A recent presentation from Cambridge Wireless event is embedded below:

Augmented Reality on the 'Peak of Inflated Expectations'

In a recent event in Cambridge Wireless, one of the topics of discussion was where does 'Augmented Reality' sit on the Peak of Inflated Expectations. While one of the speaker thought that it was on the Peak going towards Trough, most of the others thought that it had already passed the trough and is now going up.

Some six months back I put a picture up from the Gartner Hype Cycle that showed that the Augmented Reality is at the peak going towards the trough.

What do you think? Any opinions?

Problems with 800MHz in UK and Spectrum to be auctioned

Even though 800MHz provides far better coverage than 2.1GHz (as shown above), it is going to be difficult to rollout LTE on 800MHz in the short term. The main reason being that there are quite a few other devices that use the frequencies or the frequencies neighbouring the 800MHz band and the interference may stop them working. A chart of the users is shown below.

It would be interesting to see when the rollouts in 800MHz would happen.

According to Ofcom, the following spectrum will be available in the UK:


• 250MHz of spectrum:
    • 2x30MHz paired at 800MHz
    • 2x70MHz paired at 2.6GHz
    • 50MHz unpaired at 2.6GHz
• (Also 2x15MHz of 1800MHz spectrum to be divested by EE)
• Starts to become available from Jan 2013
    • 800MHz expected to be available across whole of the UK by end of 2013
    • 2.6GHz across majority of UK by end of 2013 with remaining areas asap thereafter

All these topics were recently covered in a Cambridge Wireless event on Mobile Broadband SIG: Mobile Broadband in Rural Areas. The presentations are available here to view and download.

Adding new dimensions to the future phones - Smell

I am going to be involved in two events in the coming months to discuss about Evolution of Devices in the future. The first of them is the LTE World Summit that I have been going to for years and have recommended to lots of clients, colleagues and friends. In there I will be discussing about 'The Future Device' in the Breakfast briefing. In June I am chairing a session on 'Where Next For Devices' in The Future of Wireless International Conference. As a result I would be discussing some ideas on the blog with the intention of getting some valuable feedback and comments.

Smell has been associated with the mobile devices for a long time. There are two concepts floating around. The first is a phone that can smell the environment for certain odour or harmful gases and depending on what it smells, alerts the user or some authority. An example of this are the phones being developed by US Department of Homeland Security to smell poisonous gases. Another example is the e-nose concept developed by Imec, Belgium. There are other concepts being developed around m-health to help people with Asthma.

The second of these concepts are the devices that can emit smell. The simplest form of this would be like the Sony phones that emit fragrance for a few months and then a new sheet can be inserted for them to keep emitting a fragrance. A while back it was reported that Samsung has filed a patent for something similar.

Nokia had shown years back the 'Scentsory Concept' mobile that can transmit smell based on the environment to the other party who can get the feeling of where the other person is. Since then they have shown other concepts but I dont recall seeing much on smell. The 'HumanForm' concept I blogged about last year showed that we would be able to feel the environment but it was surprisingly quiet about smell part.

There is an interesting TEDx video in which Jenny Tillotson, who would be presenting her latest research in the Future Wireless conference mentioned abaove, is explaining some of these concepts on transmitting smell electronically. Video embedded below:



I would be very interested in hearing more on this topic from the readers.

Future Mobile devices: Winners & Losers in technology

NTT DOCOMO announced a range of futuristic ideas and products that they are going to demo at CEATEC this month. Some of the products/ideas as follows:

Extra-high-speed, next-generation LTE service

• Experience the first Xi-compatible tablets “docomo Tablet GALAXY Tab 10.1 LTE SC-01D” and “docomo Tablet ARROWS Tab LTE F-01D,” set for October release.
• Try out new broadband services for the high-performance Xi network, including internationally popular services and games such as Hulu and Qik Video.

Smartphone-ready device to measure acetone in breath for diet support

• The compact device measuring acetone for diet support that can easily be used anywhere and anytime.
• Visitors blow into the smartphone-connected device to measure acetone in their breath-the higher the concentration, the greater the level of hunger.
• The device also identifies when people are burning fat, based on the concentration of acetone in their breath, which rises when body fat is being burnt.

Smartphone jacket for ultra-high-speed battery charging

• This special battery jacket for smartphones achieves a full charge in just 10 minutes. A recharging indicator will show how the jacket will charge a smartphone 10~15 times faster than conventional charging devices.

Smartphone jackets for various purposes

• Three types of special jackets for smartphones that are equipped with sensors that can be customized to measure ultraviolet light and bad breath, gamma radiation and body fat.

Environmental sensor network

• Presentation of real-time atmospheric data (temperature, humidity, wind direction/speed, precipitation, ultraviolet intensity) collected by DOCOMO’s nationwide network of approximately 2,500 environmental sensors, and a demonstration of visualizing the data using augmented reality.

The DOCOMO booth will also offer a mobile handset recycling service, where visitors can drop off old and unwanted mobile phones, rechargers, battery packs and stands. This service is open to all mobile phone users regardless of their carrier, and mobile phones will be destroyed using specialized tools to ensure the protection of personal information.

You can watch these in action here:

I also recently attended a Cambridge Wireless Handset SIG event and David Wood gave an interesting presentation that is embedded below:

Mr. Edward Zhou, CMO of Western European Region, Huawei Technologies Co. Ltd.

• states they have 5300 people in Europe but only 65% are from local market

• No. 2 telecom solution provider with revenues of $28 billion

• has 110,000+ employees with 150 nationalities worldwide, more than half work in R&D

• By 2020 there will be 5.5B MBB (Mobile Broadband) users as opposed to 1.5B FBB (Fixed Broadband)

• 70% of companies (especially SMEs) will be using cloud based services.

Mr. R. Swaminathan, Senior Executive Vice President, Reliance Communications Ltd.

Kanwar Chadha, Chief Marketing Officer and Board Member of Cambridge Silicon Radio

• Innovations in location-aware wire-free connected world

• Spoke on view of local business vs global, very entertaining perspective , assume nothing and be careful of interpretation

• Example is the initial GPS cost $3700 but was still successful in Japan because guys wanted to show it off to their dates.

• Maslow's hierarchy of needs dont work for India as its more important to have entertainment (TV) than roof.

• FM very succesful in India but nowhere else.

• Sat Navs will not succeed in India because addresses and maps not very well mapped. Things like coupons, sms will be very successful

Innovation Hothouse: Mr. Christian Leicher, Member of the Executive Board at Rohde & Schwarz GmbH & Co. KG.

Session on start-ups very interesting

• Augmentra talked of GPS based smartphone apps. Users can share and get paid when someone else download what they share. Their guidebooks, etc are trusted by half the search and rescue mountain teams

• Oxems have a solution for the new plastic pipes that are being deployed. The normal metal detectors cant detect these pipes so they have a RFID based solution.

Smart Meters Data and Privacy

I have in the past discussed about Smart Grids and Smart meters in this post and have mentioned some of the privacy concerns. Each electrical device has its signature which could be exploited by some rogue elements to find out if there are any people in the household or itss empty. If its empty they could take advantage by breaking in the house, etc.

Last week I heard a presentation by Onzo in a Cambridge Wireless event about Smart meters (embedded below). This was the most detailed presentation I saw that explained how this data from the smart meters

If you browse the slides you will notice that the device signatures can be used to pinpoint the type of device and in most cases also the make and model of the device. It can even point out if a device is malfunctioning or about to breakdown. The customers can get a detailed summary of the main appliances in the house and how much electricity they consume and this would be without any physical intervention in the electrical circuit in the place.

I am sure that are many positive uses of this data and can be used by various governmental agencies to learn more about people behaviour, use it for monitoring crimes (think CSI) and many other advanced services that may not yet be imaginable but the privacy concerns and worries will remain.

The presentation below starts from slide 21 that shows the data part but feel free to view the previous slides.

The First 50 Billion Data Points

Finally, I would like to mention that most of the information I have seen about Smart meters actually only include Electric meters. I find it difficult to foresee how we would have smart meters for Gas, Water and Sewage and how the data can be exploited in a positive way.

Cognitive radio – the way out of spectrum crunch?

Another presentation from the Cambridge Wireless Event on Avoiding Cellular Gridlock. One of the ways suggested in the discussions with regards to the 'Geo-location database' (see slide 12) is that they could also be done using Smart Grids. Though it sounds simple in theory, practically we may never see that happen and that would not be due to any technical reasons.

Mobile Phone Antennas and Networks

We all remember the so called 'Antennagate' where the iPhone 4 loses coverage due to the way its held. As can be seen from the above picture, there are a lot of antennas already in the phones and yes they are on the increase with LTE and other technologies being added all the time.

Apple admitted the fault and claimed to have fixed the problem but its well known in technical circles that the fix is more of a software hack which doesn't really fix the problem just pretends to fix it. That is why the networks dread it and you can find awful lot of information on the web about the problems.

In a recent Cambridge Wireless event, I heard an interesting talk from Trevor Gill of Vodafone and one of the slides that caught my attention was the impact of these poorly designed phones on the network. The slide is embedded below.

It is estimated that the RF performance of iPhone4 is around 6dB worse than most other 3G phones. What this means is that you may be getting 4 bars of reception on your other phone where iPhone4 may be having only 1 or 2 bars or reception. So if the reception is poor with 1 or 2 bars, iPhone4 may have no reception at all.

To fix this problem, either the networks can increase the number of base stations to double the existing amount which is a huge cost to the networks and extra radiation or the phones can fix it themseles by having an extra antenna. In fact as the slide says, extra antenna on each phone would translate to increase in network capacity by 20-40%, cell area by 30% and cell edge throughput by 40-75%.

One final thing that I want to mention is that testing (RF, RRM, Conformance, etc.) are mandated by the networks for most phones but they overlook the testing procedure for phones like iPhone. What this means is that they do get a lot more new customers but they get new sets of problems. If these problems are not handled well, the impression they give is that the particular network is rubbish. Another thing is that the devices use a certain build/prototype for testing but the one that they release may contain other patches that can cause chaos. One such problem was Fast Dormancy problem that I have blogged about here.

Hopefully the networks will be a bit more careful and will put quality before quantity in future.
