WHD.local event in London – free Samsung Galaxy Tab

Earlier this week Lonap agreed to promote a WHD.local event that is being held in London next week. It’s the baby brother of the big one in Germany in April. Lonap Director Will Hargrave is doing a very interesting talk that you should all go along to. Also there is a free lunch and free drinks at the post conference networking event.

The old adage has it that there is no such thing as a free lunch but on this occasion it needs to go further because they are also offering a free Samsung Galaxy Tab!!!!!????? wtfwtfwtf (that’s a NLA).

The only thing is you have to visit every booth on at the trade show and get a stamp on a card. So you do have to do something but in my mind that’s a gift horse you definitely should not look in the mouth. I’ve not looked to see who is exhibiting or how many there are (ok if it is hundreds of companies I’d look that horse in the mouth but I doubt there are).

Other than the fact that I am a Director of Lonap I have no vested interest in promoting WHD.local, and all Lonap is getting really is some exposure unless enough Lonap members sign up in which case we get a private room in which to have our own private lunch.

The reason I have posted this is because I’m not sure I’ve ever heard of a trade show giving each of its attendees a Tab before. Is this a first?

Click on this link if you want to go. LWGVWE4 – Click here to sign up for WHD.local 2013!

Also let me know if you do sign up. I’m not going to be there due to other commitments but if enough people get in touch I’ll arrange the private get together.

html of the official invite is linked to here – Mailing_LONAP_EN.  There’s some more photogenic stuff in there including a picture of Will. I couldn’t be bothered to work out how to embed it so you just get the link.

Hasta la vista baby…

PS my signoffs are getting somewhat off the wall. I must be going crazy hahahahahahahahaaaaaaaaaaaaa.

4G better than hotel WiFi – official

Sat in my garrett at the Cromwell Hotel in London getting ready to to a 5.30 meeting. There is great 4G coverage here from O2, Vodafone and EE. The hotel WiFi is totally pants. It’s so slow it won’t even connect.

During my 4G test trips I already concluded that it is better to use 4G than the WiFi of a pub or cafe. I can tell you after my scientific survey (sample size one)  that this is also the case in hotels.

It’s such a pleasure to have the connectivity on the move. This post is coming from my Samsung Chromebook hooked up to the Huaweii MiFi loaned to me my EE. On the train on the way down I also used the MiFi – it was tucked in my coat pocket so to all intents and purposes the Chromebook was “just accessing the internet directly”.

Now all I need to do is to figure out how to convert Microsoft presentations to Google format (see previous post).

Pics below are screenshot of speedtest on O2 4G on Samsung Galaxy S4 plus screenshot of “error” message when it failed to connect to Cromwell Hotel WiFi.

It’s offical, at this Best Western Hotel, 4G is best 🙂

Wireless connectivity during the “connected” Olympics

Olympic long jump great Bob Beamon who is taller than Trefor Davies helped with the WiFi testing if he but knew itIn February I wrote about the O2 4G trials in London. The trials involved travelling around the city with a laptop and a 4G dongle looking for fast mobile internet access. Six months later I was back on holiday in London for the Olympics, billed as the “connected games”. As I was due to spend 8 days out of the Olympic fortnight in and around Olympic venues I thought I’d follow up the earlier 4G exercise with some mobile speed testing.

Highlights include the Apple Store, Virgin Wifi on platforms on the London Underground, the Cisco House at the Olympic Park and BTOpenzone at the Waldorf Hotel.

To test the 3G and WiFi networks after 4G seems the wrong way round but is still valid. The rise of the WiFi hotspot combined with the continuous increase in mobile data capacity are elements of the new mobile battleground for network operators. You don’t need to be a mobile operator to play. WiFi is strategic for both fixed and mobile players. It’s a competitive play amongst broadband providers and an offload mechanism for mobile players wanting to reduce the load on their cellular data networks

For the tests I used my Samsung Galaxy S3 and a couple of different apps from speedtest.net and thinkbroadband.com. The two apps produced slightly different results but in the great scheme of things were broadly the same – when the connectivity was good they both said it was good.

Rarely can a set of technical tests have been conducted in such interesting and historical surroundings. I started at home in Historic Lincoln on 31st July and did a quick test whilst still in bed at 5.52am getting around 8Mbps down and 400k up using my home broadband (boy am I looking forward to FTTC).

We stayed that night with friends in Historic Windsor. Their WiFi was up and down and the cellular data connection was near to non-existent at 11k down and 85k up.

In the morning of 1st August we were heading for the Millenium Stadium in Cardiff to watch TeamGB beat Uruguay. I jumped on the 15 minutes of The Cloud’s free WiFi at Historic Slough railway station and got a reasonable  5.9Mbps down and 1.6Mbps up. Upload speed is becoming just as important for me as download as I back up all my photos and videos to Google+ and like to post to YouTube.

Interesting that the WiFi at our friends house in Cardiff was a poor 1.6Mbps down but 3Mbps up. O2 mobile data speeds at the Millenium Stadium in CardiffI couldn’t get on the WifI at the Millenium stadium because I needed a BT Logon and being tight I didn’t want to pay for it. However the O2 mobile data connection was absolutely terrific at 7.7Mbps down and 1.5Mbps up. At half time as the 70,000 in the stadium switched their attention to their phones  the speed dropped to 3.7Mbps down and 0.8Mbps up. Still very usable.

I was very very impressed with the mobile data service in the Millenium Stadium. My first true Olympic experience. I experimented with uploading blog posts using WordPress for Android. Without photos this was no problem. It struggled with big attachments though and I found later that this was very much a function of the upload bandwidth available for that application – faster the better obviously.

At the Millenium Stadium I was also seeing how well the battery would last on the Galaxy S3. I went in fully charged at around 5pm and hammered the phone by taking lots of photos (bursts of 20 at 3 frames per second) and videos and with using the 3G data connection. After 3 ½ hours I still had 24% batteryGalaxy S3 battery and wireless data usage left. I took 273MB worth of photos and videos whilst in the stadium. On the 1st of August I used 180MB of mobile data in total, 74MB of which was accessing the phone’s photo Gallery which downloads images from Google+!  Speed testing used 27MB of data on that day.

The next day I took the kids to Lee Valley to watch Team GB win Gold and Silver in the men’s doubles kayaking slalom (yay). This was an outdoor venue as opposed the near indoor nature of the Millenium Stadium but I was happy with 3.4Mbps down and 1.5Mbps up.

The free Virgin Media WiFi in underground stations was a revelation.Virgin Media WiFi speeds on the London Underground station platform at Covent Garden In Covent Garden Underground I got 26Mbps down ad 44Mbps up! Wow. My biggest problem was that you didn’t have enough time to reconnect for the brief time the train spent in stations once you were onboard. Once on the train you realistically had to abandon any expectation of using WiFi for the remainder of your underground journey .

Also in Covent Garden the Apple Store gave 11.7Mbps down and speed test at Apple Store in Covent Garden - a great place if you need easy and free access to good WiFi25Mbps up. You may have noticed a theme here. The uplink often seemed to be faster than the download but I guess that’s to be expected as most other users on the hotspot will have been downloading and sharing that bandwidth. This was the same at Lancaster House on the Friday (25Mbps down 31Mbps up) where I actually had to do some work at a Foreign Office Business Embassy meeting and the following week at the Cisco House WiFi speeds at the Cisco House - click to see the view from the balcony(21Mbps down 48Mbps up – they 50Mbps of internet access and 2x10Gbps backup if they needed it!) where I was entertained to Corporate Hospitality along with Dr Henry Kissinger and legendary US long jumper Bob Beamon.

Henry Kissinger is shorter than Trefor Davies

I had been looking forward to trying out the WiFi in the Olympic Park itself having got myself a 5 day Openzone logon. On Thursday 9th August at the Aquatics Centre for the Womens 10m High Diving finals – my first day of using it – I couldn’t get on to the network. It transpired that the BT WiFi landing page didn’t like the Chrome browser running on my Galaxy S3, the official phone of the Olympics!  Back the next day for the mens handball semi finals between Hungary and Sweden I found that the native browser on the S3 worked ok and I did get  WiFi connectivity.

The speed testers initially didn’t show much speed so I tried uploading a video of the handball to YouTube. It took a 69MB HD video file 18 minutes to upload which in my mind works out as roughly 0.5Mbps upload speed. I did eventually register 2.87Mbps down and 1.6Mbps up at the Handball.

The cellular speeds at the Aquatics centre ranged between 1.7Mbps andAquatics Centre O2 Cellular data speeds 5.4Mbps down with uploads between 32Kbps and 1.6Mbps.

After the Handball I did test the Wifi at various spots in the Olympic Park. It waxed and waned a little but I did see 8.3Mbps down and 3.2Mbps up at one point.handball cellular speeds were generally better than the WiFi
handball wifi speeds - I uploaded 69MB video in 18 minutes

 

 

BT say they had over 50,000 unique users register on their WiFi network in the Olympic Park. This must be lower than they had been expecting considering the total number of visitors to the site in the fortnight.  I guess that unless you were getting it free as a BT broadband people would have been put off paying.

The Olympic Park WiFi did prove to be reliable with 100% uptime for the whole period of the games which is good considering the shaky nature of the technology. In fact the whole Olympic experience from the network operator perspective was great. All the hard work put in to ensure there was enough internet capacity for everyone paid off.

I did have a few more comparisons. The Travelodge in Covent Garden was giving me just over 4Mbps down and 1.6Mbps up but the Waldorf HoteBTOpenzone WiFi at the Waldorf Hotel was terrificl where I stayed for the Hyde Park Blur gig on the Sunday night showed a whopping 20Mbps down and 26Mbps up. You get what you pay for. The Travelodge was a cellular connection as I didn’t want to pay extra for the WiFi and at the Waldorf I used the BT Openzone login that still had a couple of days left on it so that was free. Interesting contrast of hotels I hear you say? I paid less for the Waldorf than I did for the Travelodge the week before – crazy mixed up Olympics hotel pricing.

At the Hyde Park gig itself you could kiss goodbye to data connectivity unless you had access to BT’s own office WiFi, which I did and which gave me a variable result around the 3 – 4Mbps down.

I did try to pick up Wifi wherever I was in London. At various times I could see Virgin, The Cloud, O2 and BT hotspots. They were rarely satisfactory if you were walking around but I guess they are intended for use whilst inside a venue. Cellular was fine the whole time.

In conclusion I did find some great connectivity in London and at Olympic venues. 3G was more reliable but where WiFi was good it was great. I sometimes found that whilst there was WiFi I had to pay for it which I didn’t like so I went without.

The UK is going to be an interesting mobile battleground over the next couple of years. I think 4G is going to prevail outdoors. Owners of indoor venues will I believe have to offer free WiFi or somehow accommodate multiple providers of WiFi that offer free access to their own subscribers.

Looking at my phone data usage for August (up until am 22nd) I used 2.02GB of 3G data and 14.83GB of WiFi. This is largely because I took 7.63GB of photos and videos in the same time frame which were all backed up to Google+ over WiFi. If we assume that my own usage pattern is how the rest of the consumer world will operate at some point then a mix of WiFi and 3G or 4G is always going to be needed unless mobile data costs come down to match those of broadband which seems unlikely in the near term.

Aargh it’s 30 degrees and the Eastcoast train aircon is broken!

the temperature in London today hit 30 (feels like 32 according to my phone) and the train aircon is broke!It’s the hottest day of the year so far. People are frying eggs on car bonnets and the homeless have left London for cooler climes – it’s too hot underneath the arches for a comfortable kip.

The suits are sweating buckets and wishing it was acceptable to turn up for work in shorts. The ladies are looking lovely in the summer sun.

Most people are complaining about the heat. Those that aren’t are taking the mickey out of friends  just packing for their annual holiday in Marbella or Benidorm  or Lanzarote or Torremolinos – you know  – places less warm than London.

School’s out. Urchins run wild in the radiatingly hot city streets, shrieking under plumes of water escaping from broken fire hydrants. Their parents, sapped of care, languish in the little shade afforded by the concrete tenements they call home. There is no breeze. There is no letup from the infernal heat.

In fact neither is there any air conditioning on this train – the 18.30 Eastcoast from Kings Cross to Edinburgh stopping briefly to let me off at Newark to get my connection to Lincoln. I’m on my second can of diet Coke and second bottle of sparkling water with ice!

This must be what it is like on the Chennai to Bangalore Express (dep 13.00 arr 14.45 daily). At least those in steerage can catch a little breeze sat on top of the carriage

Ah well.

Yes please love – another bottle of mineral water with plenty of ice. Thanks…

PS I realise there are no fire hydrants in London. These are images more typical of New York in summer. Also the choice of Indian train service was purely random. However they both made the cut for artistic effect. Final answer.

Olympic snippet

Usain Bolt - billions of fans want to see him win at the London 2012 OlympicsLittle Olympic factoid for you. The last time the Olympics were held in London, in 1948, there were 2,000 press representatives. This time around there are going to be 22,000 media people. Most of them will be over to cover the women’s beach volleyball finals which is why there weren’t many tickets for the rest of us.

You can picture the scene. The small cordoned off area normally called the press box will actually contain the paying punters whilst the rest of it is for the journos and photographers. Those in the cordoned off area will not be allowed to take photos because they will be the few unaccredited persons at the venue.

I’m a bit cross I didn’t think of this earlier. It might have been cheaper to buy a press accreditation (global blog audience etc) than buy actual tickets for events and that almost certainly gives you all areas access to the last night party. The kids could have come along as camera bag carriers etc.

They might have been a bit suspicious when they find out I was just using my Samsung Galaxy S3 with its camera burst mode. Usain would probably come out a bit blurred but it would give you a feel for the event.

Ah well I’ll have to think of that for the next time.

Location, location, location – first mover advantage and the strategic nature of lamppost ownership – LTE

In the wifi hotspot game first mover advantage is becoming critically important. Experience shows that landlords everywhere are initially happy to allow a network provider into their mall/stadium/building. Once in however they decide they don’t want the hassle of doing it again or don’t really like the infrastructure they are now stuck with but have to keep.

As a result there is a market for the first movers in reselling capacity or subletting space on their infrastructure. We are therefore seeing a land grab in places around the world where operators are snapping up as many sites as they can.

In London The Cloud is looking at 1 hotspot per 200 persons. Time Warner is putting 15,000 wifi access points in Los Angeles and PCCW have 10,000 hotspots in Hongkong where peak time traffic has 50% going over wifi instead of mobile networks. For PCCW in Hong Kong their resold wholesale wifi capacity is their single biggest revenue stream1.

Did you know? some facts from around the world on LTE / 4G

iPlayer screenshots using 4G - multiple simultaneous streamsDid you know1 that LTE was launched in the USA in December 2010 where a most aggressive competition between operators has been taking place, led by Verizon? In the USA LTE has high penetration across all devices, comes at no premium over 3G data services and LTE users typically use around 50% more data than 3G users.

LTE was also launched in Germany in December 2010 but has had a slow adoption rate with the initial focus being on fixed/mobile substitution. This I understand is in part due to regulations ensuring that owners of LTE bandwidth have to service “the final third” as part of their licensing arrangements. There isn’t much of a choice of devices on LTE in Germany.

South Korea was relatively late to the game here. They launched in July 2011 but had nationwide coverage by mid 2012 and has the highest penetration rate, focussed mainly on selling to consumers. LTE has brought innovative new services to the South Koreans  eg richer high quality interactive maps.

Norralorrapeople know this. Brings the scheduling of 4G in the UK into perspective doesn’t it?

O2 LTE – the game changer

iPlayer screenshots using 4G - multiple simultaneous streams4G is like lightning, it’s an eye opener and seriously enhances the mobile data experience. This post talks about the truly exciting O2 4G trials in London and thinks about how the technology is going to change the mobile game.

Mobile data is already an important feature in the business communication landscape. As an ISP we see demand for it in the area of machine to machine, rapid site deployment, backup solutions for Disaster Recovery scenarios and of course straightforward internet browsing and email access from mobile devices.

The strategic importance of mobile data has even led Timico to invest in an Ethernet connection direct into the O2 network. We can now offer mobile MPLS solutions that sit within the same environment as existing fixed line MPLS networks – ideal for businesses that need security in both fixed and mobile networks.

Over the last year or two in the UK the focus in fixed line broadband has been on Fibre To The Cabinet, or in marketing jargon Fibre Broadband. With downlink speeds of “up to”40Mbps (to be upgraded to 80Mbps this coming April) the technology is revolutionising how people use their broadband connection. Add in the growth in high quality streaming video and gaming services and it is easy to see how the additional available bandwidth will be consumed.

Until very recently the mobile world, in the UK at least, has remained firmly in the domain of 3G – a technology that now seems relatively stone aged compared with Fibre Broadband. HSDPA makes the experience more bearable but it is still many Mega-bits apart from its fixed line counterpart.

The mobile companies are poised to change all this with LTE (Long Term Evolution) otherwise known as 4G. Trials are being conducted in a small number of locations in the UK.  Timico is the first O2 Service Provider partner to be invited onto their London trials I am pleased to be able to report on my experiences.

This service is like lightning. It’s fast, speedy, call it what you like it’s a life changer. It’s been one of those projects that has been a pleasure to be involved in.

With only 25 masts around central London coverage is nowhere near what you would describe as ubiquitous but this is only a trial. When in a coverage area the speeds are great.

I started off in McDonalds at Kings Cross with a dongle fresh out of the box. After installation of the software, which was easy, the dongle performed an automatic firmware upgrade, also easy, using its own 4G connection.

At McDonalds I was getting over 13Mbps down 4g speeds at McDonalds in Kings Crossand 540Kbps up which in my mind was a bit disappointing though I’m not sure it should have been. I have experimented with O2s 4G at their offices in Slough and seen much faster speeds both up and down  than this. In fact this speed at McDonalds is faster than I get from my home ADSL2+ connection so I couldn’t grumble.

I knew I could do better than this. Roaming around town on the top deck of a number 25 bus I got 15.5Megs down4g speeds atop a number 25 bus in London and amazingly 25Megs up – near Wardour Street. The ping times for all these measurements were impressive.

In torrential rain I moved around on foot dipping into various places to check out the speeds and moving generally towards known good hotspots.

In the end I took shelter in a pub called the Devonshire Arms on Duke Street, just off Oxford Street. Sat in the window and sipping a cup of tea I hit the jackpot with4g speeds seen in the Devonshire Arms on Duke Street 40Megs down and 23 Megs up. I did various tests including varying the browser – Chrome was much better than IE. I also did video calls with both Timico’s own VoIP service and Skype.

The screenshot on the right is of four iPlayer daytime TV streams.  The things you have to do to get a blog post written!

multiple iPlayer streams on a single screenshot using O2 4g

The highest I have seen recorded  is 97Megs in the O2 Arenaspeeds seen on o2 4g trials at the O2 Dome itself. The 2,600 MHz LTE itself will go to 150Megs but the dongle tech doesn’t currently support this. We do have to remember this is very much a test rather than a production rollout so it isn’t going to be perfect but even considering this the experience has been great.

There were a few observations to be made out of this trial. Themobile data usage increases dramatically with the higher available speeds of 4g raw speed I saw with O2s 4G was terrific when in good coverage areas. The amount of data you can download in a very small amount of time is going to change the game. In upgrading the dongle firmware for example I used 50MB in around a minute. If you consider that until recently a typical “fair use” policy for an “unlimited” data package was 500MB then you can see that the model is going to have to change. The backhaul capacity that mobile operators are going to have to build in to their networks is going to have to see growth measured in orders of magnitude.

Spectrum allocation for 4G rollout is going to be very important. At 2,600MHz the bandwidth you can get is much higher than at 800MHz, say. However the in-building penetration at the higher speed is not as good so the overall network design represents an interesting (though not insurmountable I’m sure) challenge for engineers. This makes the forthcoming Ofcom spectrum auction important – there is a mix of spectra that is going to be optimum for commercial success.

As a side note it is going to be interesting to see how much the operators are prepared to pay for spectrum – they all think they overpaid for 3G but the demand has not been there for most of the time that 3G has been around. It is different this time and people are starting to get used to paying for the bandwidth they use.

From an end user perspective the ability to have genuinely fast internet access on your laptop, tablet or mobile phone is going to change their experience. Whilst WiFi is becoming more common, at least in pubs, coffee shops and other public places the need to authenticate is still a nuisance. Also not having to wait whilst a screen loads up on your mobile phone needs to become a human right!

It is certainly going to drive more business into the mobile environment. Timico, for example, gives all its salesforce an iPad so that they can demonstrate Timico applications and our customer portal on the fly at a customer’s premises. An iPad with 40Megs of bandwidth all of a sudden becomes a low cost endpoint for a telepresence HD conferencing system.

The gaming experience is going to be great1. Who knows what mobility combined with high speed internet will do for that industry, freed from the shackles of the lounge or the bedroom. City wide action games? Orienteering for the 21st century?

The use of mobile technology for backup purposes will also extend into many more areas of businesses. Typically 3G is used where only low bandwidth is required or where any bandwidth is better than no bandwidth. 4G becomes a viable solution for offices – even company HQs.

Of course with many more people on a production 4G network the average speeds available may well come down but LTE really is a game changer.

Footnote

It’s nice to to be in a position of being able to play with these new toys but there is a very serious business side to this. As those of you who have met me recently will probably know I’ve been testing  the technology for a few weeks now – Timico is the first O2 service Provider partner to be given access to their 4G network. It forms part of the long term mobile data strategy of our business and follows nicely on from the direct connection into the O2 network I referred to at the start of the post.

I should finish off with a big thank you to O2 for including me in the trials. It’s good to be able to work with such a progressive partner.

I’m Just a Big Kid, Really – Excited about the Olympics

Usain Bolt - billions of fans want to see him win at the London 2012 OlympicsJust had a communication through from BT re planning for the Olympics. This year the good citizens of the United Kingdom are divided into two camps – those that are looking forward to the Olympics, think it is a great thing and are really excited, and those who think it is a huge waste of money that would be better spent on hospitals and schools and have been whinging about it ever since it was announced.

I am excited. What’s more I have tickets for me and the kids to see the kayaking slalom finals aaaand we have some great friends in Windsor who have kindly agreed to put up the whole noisy lot of us (and before anyone chips in we aren’t kipping at Windsor castle – they already had too many people staying). That for those of you who know the Davies’ (6 of us) is a big ask.

I’ve already posted about the expected growth in traffic on ISP networks during the Olympics. Interesting research just in is a look at the lessons learnt from the Vancouver Olympics.

Olympics Broadband Numbers BT Style – #Olympics #LOCOG

Usain Bolt - billions of fans want to see him win at the London 2012 OlympicsThree years or so ago someone placed an order with BT. Uhuh!  But this was no ordinary order. The order read something like this:

  • 80,000 connections across 94 locations
  • 4,500 miles of internal cabling
  • 60Gb per second available bandwidth
  • 1,800 wireless access points
  • 16,500 telephone lines
  • 14,000 SIM cards
  • 14,000 cable TV outlets

Juicy eh?  If you were a BT salesman taking that Olympics broadband order you would be planning your retirement. Unfortunately it isn’t that simple.  This is what BT is providing for the 2012 London Olympic Games and the order was probably taken by CEO Ian Livingston himself1 .

There are other interesting numbers to dwell on.

Boris Johnson promises WiFi for London

Mayor of London Boris Johnson has promised full WiFi coverage of London in time for the 2012 Olympic games. It would be ironic if the Olympic Games WiFi coverage was shut down because someone had been caught indulging in online copyright infringement. As Mayor will he be the one having to turn up in court?
