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.

4G Spectrum snippets – why LTE spectrum is important

Spectrum is the key resource in the mobile network game. It is what the operators paid billions of pounds (arguably too much too soon) each for during the 3G auctions. Users for the services weren’t there and nor were the handsets that would encourage bandwidth consumption.

It is a different game today. Don’t be surprised to see even greater sums of money paid for 4G spectrum. It would be commercial suicide for a mobile operator to not have any.

Spectrum when allocated is then divided into 20MHz bandwidth slots. 20MHz of spectrum allows for an 80Mbps data throughput using LTE. If you double this to a 40MHz slot you double the throughput. The higher the spectrum frequency you have therefore the more capacity your network can handle.

The downside is that the higher the spectrum frequency the lower the range and the harder it is to penetrate objects such as buildings. The lower frequencies are preferred for rural deployments – Vodafone in Germany used 800MHz for this. There isn’t a “right mix” of spectrum to own however. Vodafone operates in 30 markets and each market has different spectrum requirements.

That’s all folks…

LTE – the 4G deployment nitty gritty – macrocells and small cells

The mobile networks are built up from thousands of base stations around the country, connected back to the operators’ core networks using a variety of backhauls. Once the media hits the core network the voice/data session is directed as appropriate.

The backhaul technology has developed over time from E1s/ATM to Ethernet (fibre) with wireless connections thrown in where necessary.

Base stations, known in the business as Macrocells, contain the transmission and battery backup equipment to support a variety of call and data handling capacities (typically up to 250 simultaneous users) dependent on location. This equipment has historically taken a lot of space – it would probably fill the average master bedroom at home, requires expert installation and, because there is a mast involved to hold antennae at some height, needs Local Authority planning permission.

Technology developments mean that this kit can now fit into a single wardrobe.

IWPC LTE Small Cell Deployment Strategies Workshop – the funicular railway in Dresden

If you’re wondering what these seemingly random travel related posts are its because I’m in Dresden this week at the IWPC workshop on LTE small cell deployment strategies. Very interesting. These are long days though so you will probably have to wait until I get home for a report.

The video is of the funicular railway that took us up to the Luisenhof restaurant in Dresden. The view from up there is spectacular, or so I’m told. It was chucking it down when we were there so we couldn’t see much. We probably wouldn’t have noticed anyway – far too engrossed in the subject of LTE small cells.

Legislation encourages tidal wave of new ISPA members – life jackets at the ready

It’s a funny old world. A judge orders ISPs to cut off access to Pirate Bay and visitor numbers to the site increase by 12 million. A government says it wants to increase the amount of regulation on the internet and the membership of the trade association shoots up.

The membership of ISPA normally hovers just under the 200 mark. The nature of our industry is that companies are bought out or merge with others to get scale. So in any given year the we get perhaps 10 or 15 new members but 10 or 15 disappear off the UK internet map and on the whole the number stays the same – ish.

Things are changing. The threat to the  industry stemming from potentially onerous new regulations placed upon service providers, such as the upcoming Communications Bill Green Paper, has prompted six new service providers to join ISPA in the space of one month. This is a veritable tidal wave in the scheme of things.

I could never be a politician – The Queen hath spoken

I could never be a politician. The Queen’s Speech today included a Lords Reform Bill, Draft Communications Data Bill, Banking Reform Bill, Energy Bill, Enterprise and Regulatory Reform Bill, Children and Families Bill, Pensions and Public Service Pensions Bill, Crime and Courts Bill, Croatia Accession Bill, Electoral Registration and Administration Bill, Defamation Bill, European Union (Approval of Treaty Amendment Decision) Bill, Groceries Code Adjudicator Bill, Justice and Security Bill,  Small Donations Bill together with Draft Draft Care and Support, Local Audit and Water Bills and Carry Over Bills on Civil Aviation, Financial Services,  Finance (No. 4), Local Government Finance and Trusts (Capital and Income).

I’ve listed them in one long string for effect. I guess I must be interested in the outcomes of some of them as they affect me – comms data for one. It has to take a very particular sort of person to want to become a politician. We pay politicians to sort this stuff out but do have to keep an eye on them because as we all know they can get a bit out of control.

The Communications Data Bill which caused such a lot of fuss a few weeks ago when it was leaked to the Sunday Times that it would include surveillance seems to not be getting any attention in the media today with things like Lords Reform hitting the headlines.

This must be remedied. We must rally the troops, man the battlements. In fact I think Shakespeare foresaw all this as you will see from this early version of another monarch’s speech:

Alternative ways of bypassing the Virgin Media filter to access Pirate Bay – Google Translate

google translate can be used to bypass Virgin Media web filters to access Pirate BaySince publishing the original post on this subject that described how to access Pirate Bay using free proxy servers I’ve had a few people point out other ways. Some were left as comments on the post itself. Some came in by email.

The most innovative is where Google Translate service is used as a proxy server. Take a look at this link:

That page is the normal Pirate Bay running though the Google translate servers, translating any African on the page to English. Obviously there is only English on the page so it displays like normal.  Apparently, according to “umm hmm” from the TheSlyrateBay.com who fed me the info, this is not a preferred method as it can sometimes be slow and a bit clunky if the Google servers are experiencing high traffic (fwiw).

Many sites have been also set up as proxies to provide easy filter bypass to get to Pirate Bay – some have been pointed out in the comment stream of my earlier post – others will be easily findable online if you look – it won’t be hard.

The Online Garden Shed – the answer to internet privacy issues

Google Opt out - the online garden shed?We all need our private space. This true in our virtual lives as much as in the touchy-feely-smelly real world that we once inhabited.  In those days man could retire to his shed if he felt the need for a bit of time to himself. He would only let you in if you were a pal.

There are no sheds online.  What do we do about privacy when using the internet? The fact that Google seems to know what I’ve been up to is a concern.  Do we all sign up with proxy services?  The proxy service provider will still know what you are up to.  Switching on “private browsing” seems a bit of a faff and all that does is prevent PC from storing usage data.

A reader (thanks HmmmUK) just Tweeted me a link to the Google Opt out page:

“Opt out of customised Google Display Network ads

Opt out if you prefer ads not to be based on interests and demographics. When you opt out, Google disables this cookie and no longer associates interest and demographic categories with your browser.”

I’ve ordered a Samsung Galaxy S3

I’ve ordered a Samsung Galaxy S3. I don’t know if it is the right thing to do. Part of me says moving to a new phone means that you should be moving to a significantly better device – I have an S2. Every new phone seems to be “just an iteration” of the incumbent spec. Certainly that’s how it seems with the iPhone and also with other devices that Samsung has brought out since the S2. I’m still on the original iPad!

On the other hand we live in a very fast moving world where even the smallest competitive edge can make a real difference. Can we ascribe this to our use of smartphones? I don’t know, perhaps. I think the S3 probably has just enough on the S2 to make it worth the upgrade. I need to do it because otherwise before I know it everyone else will have moved on to the S7 or S8 and I’ll be so far behind the times I will really have to think of packing it all in.

How to bypass the Virgin Media web filter to access Pirate Bay

How to bypass the Virgin Media web filter to access Pirate Bay

Before you start reading this post, and many thousands have, take a look at Broadbandrating – if you are looking to move ISP then the site will help you choose which one to go for.

Now the post:

Industry colleague Gary Hough left a comment on my blog post on Pirate Bay the other day. He has now written a guest post (tagged on to the end of this one) outlining how easy it is to bypass web filters to access “blocked” sites. I asked myself whether this was a responsible thing to publish. After all it flies in the face of the process of Law and Order and I am not in favour of promoting unlawful activity.

However the process described below is such common knowledge1 and there are so many sites out there providing proxy services used by millions of people that I feel that the story needs to be told in an environment/on a vehicle that promotes sensible discussion of the issue. We certainly need those in places of power to have the opportunity to read about and properly understand the problem.

The issue is not just Pirate Bay or any other site promoting the music downloads that have engendered such emotion within the Rights Holder industries. The issue is the fact that the same process can be used to bypass any web filter. This means that were we to enforce blocking of other types of website – pornography, for example, or sites promoting racial hatred or extreme political views the blocks would be ineffective.

EU cookie legislation – a look at some of the implementations

EU Cookie Directive 2009/136/ec of the European ParliamentUK Cookie legislation  (DIRECTIVE 2009/136/EC) became law on May 25th 2011. This is the one where websites are meant to give you the opportunity to opt out of visiting them if they are using cookies. Cookies can be very “invasive of privacy” though in varying degrees and some potentially not at all. The law, whilst being passed with good intentions has had some unintended consequences, notably affecting some cookie functionality that is useful and likely unintrusive.

I imagine that most of us with a website use Google Analytics. We all like to look at our traffic levels – well I do anyway. There has been some confusion as to exactly what is being required of website owners – rumours for example that sites only using Google Analytics cookies would not be made to comply as GA was “beneficial and not intrusive”.

You may or may not know that I am on the Information Commissioner’s Office Technology Reference Panel. This is an expert body of representatives from stakeholder groups in information and technology related industry sectors.

The ICO, which is the industry regulator, has given the UK a year to implement the cookie directive. This year is up at the end of this month and naturally there has been press comment and a flurry of businesses making adjustments to their websites in an attempt at compliance.

One year on exactly what will the ICO do re enforcing the law

Snooker, chainsaws and high voltage cattle prods & O2 4G LTE trial

In an idle moment last night whilst simultaneously watching the snooker and browsing Twitter I asked the important question of our time. Does anyone have a favourite agricultural equipment? This was totally random but it was amazing how many people responded – all blokes.

Rob immediately came back and said “David Brown tractor” as his dad used to build them. That’s cool especially as it turns out David Brown used to own Aston Martin (hence DB5) and Lagonda. I wonder how many gears that tractor has.

Pirate Bay now, what next?

Pirate Bay to be blocked in the UKI’ve just been on the Pirate Bay website. It looks decidedly dodgy. Ads for pornography and flashing boxes inviting you to “fix it now”. Not been on it before. Thought I’d do so before the court order kicks in.

Today a court told the biggest consumer ISPs to block access for their customers to the Pirate Bay website. Most ISPs are not affected by the order but now most consumers in the UK wanting to access the “services” provided by Pirate Bay will have to do so using encrypted paths provided by proxy servers or by accessing a mirror of the Pirate Bay site.

There is a twitter account specifically set up to provide updates of where you can find mirrors. They don’t

Ticket very much not master

ticketmaster or ticket not very much master - that is the questionI tried to buy Olympic football tickets this morning.powered (though not very well) by ticketmaster I want  to take one of my kids because he is a big fan. You know how it works.

I went onto the ticketing website at 5.30am to sign in and make sure all was well in preparation for 11am when the tickets went on sale. All was not well. When looking at my “confirmed tickets” I got the screen shown inset on the right. “We are currently experiencing high demand and the page you have requested is temporarily unavailable”. Unavailable my foot – at 5.30am!

On previous occasions the message has said that the info is not available “whilst seat allocation is taking place”. This was the message for the last few weeks. Gimme a break. How can it take so long to allocate seating using an electronic system. It can almost certainly be done at the flick of a switch.

Facebook events and doorlists

carnival time at the Davies'We had an A List party at our house on Saturday night.Hard men manning the door - street urchin hovering in background hoping to catch sight of some A-Listers The full monty – marquee in the grounds, caterers, fully manned bar and state of the art entertainment system etc etc. We even had security – nothing too in your face except at the initial checkpoint on the door. All very polite.  Although the men at the door were hard bastards they were fully trained hard bastards in dinner suits, all very discrete but you know they were there. You felt safe.

Your name, as is customary with these events, had to be on the official guest list, all pre-approved. Nobody got in who wasn’t meant to get in although the queue at one point ran down the drive and all the way round the corner.

And now we get to the point of this post which is that all of this was organised on Facebook. The attendee list was kept on an iPad by one of the doormen and everyone was checked off as they came in through the door. It must only be a matter of time until Facebook moves in on Eventbrite’s space.

Much of this party was organised online – lights, music playlist (iTunes), flooring, giant buzzer game (no idea what you call it really but the buzzer went off very loudly if the hand held thingy touched the wire). The music ran off an iPod and the DJ used a turntable / mixer app on his iPhone.

The only manual bits were the cake order from the bakers up the road, the food and booze from a large multinational retailer (could even have ordered that online for home delivery but part of the fun is going there and choosing) and the sound system which was borrowed from a mate (many thanks to Jeremy Dawkins of Next Event for this). I did also call the very excellent 18th Bailgate Scouts to ask to borrow their marquee though that too could have been done via email.

Other than handing out the cash & vetting the proposals there wasn’t much for me to do. I now have an adult daughter who will I’m sure repay me many times over by occasionally remembering her old man when she flies the coop and makes her own way in the big wide world. I will if nothing else be able to keep in touch with her on Facebook 🙂

Should you worry about your own personal information security – yes – notes from Infosec2012

crimepack - toolkit for cybercrimeI spent a day at Infosec2012 this week. I could easily have spent another day there as I only met a fraction of the people that would have been good to talk to. It’s not often I say that about a trade show.

I stopped by the Sophos stand for a looksee.James Lyne of Sophos - top cybersecurity guy James Lyne, Director of Technology Strategy of Sophos does a magnificent talk on security. He prefaces the talk with a warning not to visit any of the websites he mentions yourself because of the certainty of picking up malware. I’d take his advice.

James picks up malware for a living!  On any given day the Sophos labs identify 185,000 new discrete pieces of malware. Yes you did read that right. One hundred and eighty five thousand different pieces of malicious code designed to try and penetrated your computing device with a view to stealing your cash, new every day.

This malware is computer generated and churned out in crimepack control panela wholesale manner. The whole game is run by organised crime and is big business. Customers get access to a control panel that they use to organise criminal “campaigns”. This control panel (screenshot inset – hacked by JL) gives them feedback on their successes – how many machines infected with what, for example. They can also use it to pick their “threat vector” ie what sort of virus/trojan/malware they want to use for their particular spamshot/offensive.

These platforms even have APIs so that crooks can build them into their own resources or add their own specific features!

The gangs involved collaborate. They collate data on anti-malware products produced by Sophos, McAfee et al and can tell in real time whether these companies can detect specific threats. In real time! They also collectively contribute to produce a blacklist of IP addresses used by security products manufacturers so that they block access to their online resources from these addresses.

Many people get caught out. Very many people. They must otherwise these guys would not be in business and I’m sure that most of us know someone who has lost cash or had their PC compromised.

What on earth can you do to protect yourselves in the face of such criminal activity? Sometimes there is nothing you can do as many devices have known vulnerabilities. I saw James Lyne tap into an iPad using a fake hotspot and steal some data. He used a known iPad vulnerability. I switched off the WiFi on my own iPad and even considered wiping all those hotspot credentials stored on my pad that make it easy for me to log on the next time I visit!

It does make sense to make sure that all your software is patched up to date, especially applications such as Adobe. It might sound obvious too but don’t click on a link you aren’t sure of. It doesn’t seem to matter whether you use Microsoft, Apple or Linux. Use sensible password policies. It also makes sense, if you can, to have one separate PC that you only use for banking or ordering stuff online.

I left the show with my head buzzing and thinking I didn’t stand a chance in the big bad world of the interweb. I certainly will be reviewing our home cyber security defences. Stay safe now.

PS you should take a look at Sophos, a British company turning over £600m with 2,000 staff! Not bad.

It seems a long time ago now, the passing of the Digital Economy Act.

Infosec Europe – the stuff you really need to know

It’s interesting to see how people naturally spaced themselves out so that there was an equal gap between them and the people in different directions  around them.

I’m going to write two posts on the visit to Infosec. This one covers all the essential things you need to know. The second will take a little more serious look at some of the learningsDennis Webster of Pangea with Trefor Davies and add some thoughts.

The essential information is presented here in pictorial format. The first inset photo is the shoeshine stand at the Echoworx booth. I say booth but all it really was was a space with a popup and two shoeshine chairs, one of which I sat at – I like to look after my shoes me (Timberland – none of this Hush Puppy stuff). The downside is that for 5 minutes as a captive audience I had to sit through a sales pitch for Echoworx. It’s fair enough. I got my shoes done and they got their message across.

Government surveillance in a free society?

Time was when MI5 (or whatever they are called) wanted to listen in on your conversation they sent someone round to the local telephone exchange with some wires and a couple of bulldog clips.

The breadth of things that could be monitored was actually fairly large. I remember once, many years ago, being shown satellite photographs of the lake at the Chernobyl nuclear plant in the days running up the announcement that there was a problem with the reactor. The thermal imagery of the lake showed it warming up substantially over a few days. The information showing that there was a problem was being collected by our “security forces”.

The fact is whilst the data was there nobody saw it as it was buried in so much other information, photos etc, that you had to specifically been looking for it to see that something was wrong. The amount of personal information that they could gather about you was fairly limited and the number of people they could do this to was not huge. It was not a scalable system.

Nowadays the game has changed.

The black art of serving Guinness

Guinness - best drunk warm :)It is a truth universally acknowledged, that a manGuinness is good for you on his way home from work on a Friday night must be in search of a decent pint of beer.

We are indeed fortunate, on this scepter’d isle of ours, in having a wonderful brewing heritage that yields a terrific diversity of ciders, bitters, lagers, ales, milds and of course stouts. There is a drink for everyone.

Afficionados of the ancient brewer’s art will know that, lagers aside, most of these beers are ideally served at room temperature or cellar temperature at best.

This is particularly the case in the modern age where big business, dominated by men in suits seeking to maximise profits, abounds with “creative” ideas intended to extract as much cash as possible from a hardworking public.

One such creative idea is the notion of “extra cold” beer. It’s the same stuff, out of the same barrel but served through a different pipe and cooled by a further 3 degrees. Some people surrender to the hypnotic effects of the advertising budget and opt for this cold concoction.

Not I for I am a man of tradition, especially when it comes to my pint. Tonight whilst waiting for a Guinness, dispensed in two stages and then finally topped up after the liquor has settled for a minute or so, I was treated by the barmaid to a technical tutorial in the science of beer pouring.

Extra cold Guinness is preferred by bar staff to the warm stuff. This is because the extra cold variety pours with a much smaller head and therefore does not normally need the final topping up stage of its warmer sibling. The publican, with time and motion always at the forefront of his busy mind, clearly favours this more profitable option.

At my own local this does not affect our enjoyment of the experience and to my knowledge I personally have never been subjected to any exhortation, subliminal or otherwise, to opt for the extra cold variety.

Long may this continue – bottoms up and have a good weekend.

Raspberry Pi – the real McCoy

say hi to RaspberryPiI kinda like winding down on a Friday afternoon Raspberry Pi fresh out of the boxalthough this week has been so hectic it feels as if I need a couple of extra days to squeeze it all in.

Fridays are usually when I put up the trefor.net megaprize competition. It isn’t too late to have one this week but first I need to talk about Raspberry Pi, for yes, I have been playing with one.

The amazing thing about Raspberry Pi is that it just works out of the box. They have done a great job. The processor is a bit slower than you are used to with graphics but hey – it’s twenty five quid for petes sake.raspberry pi screenshot

The pics in this post say it all really.

The first is just the PCB. It’s almost like a mobile phone without the screen and battery. Then I have a few screens shots with the obligatory picture of the blog in it to show the browser in action.

Second screenshot zooms in to show the menu options and then I’ve shown the development environment in a window.raspberry pi dev environment You can be up and running straight away although you will need to learn some basic programming languages, which is the whole point of the device.

The last photo shows the desktop setup wit ha Raspberry Pi plugged in to an Ethernet cable. Obviously there is only one video card so only one of the screens are used.

It might almost be conceivable to use two processor cards to have two screens. I can certainly see Raspberry Pi being used in many applications around the home and office.Raspberry Pi desktop setup

Obviously the cables would have to be tidied up a bit for every day use and I expect Health and Safety would insist on a box for the processor card.

The video at the bottom of this post shows a screensaver in action. Thanks to Gareth Bryan for letting me have a play. I didn’t get in particularly early with my registration.
