Metro information displays and BGPS

For a while the Tyne & Wear Metro have had scrolling matrix displays installed in their trains, but until this morning I hadn't seen them switched on. On my commute to work today Nexus (the operators of the Metro) obviously had them in some kind of test mode, constantly scrolling the message "NEXUS METRO agps-bgps" as you can almost see on the rather rubbish photo below (it was moving text on a moving train and a phone camera, so it was bound to be bad):

Something like that isn't going to pass me by without a fair amount of curiosity.

Obviously they are going to be showing information based on the location of the train - that makes sense if the information is going to be useful. AGPS (Assisted GPS) is something that I know about - devices use data from a mobile (cellular) network to achieve a faster location fix from GPS satellites - but BGPS was a new one on me, so I looked it up.

Ordinarily I would expect there to be an article, or at least a mention in a bigger article, about something like this on Wikipedia, but I didn't see it. Instead I had to rely on a 2008 article from GPS World called Innovation: First AGPS - Now BGPS. It's a long article and assumes a knowledge of GPS that I don't have, but I'm pretty sure I understand the main points.

BGPS (named simply because B comes after A), is an adaptation of AGPS which gets round some of the limitations of AGPS. The Metro has underground sections, which do have some mobile network coverage, but obviously don't have line of sight with satellites, and when a train is in the great outdoors, it probably doesn't want to be reliant on mobile network coverage anyway - I know from experience that it's not great.

BGPS allows the side loading of the data that would come from the mobile network by using some other means. This is perfectly reasonable on the Metro network which is both tightly defined and linear, so beacons at some or all stations, or at signals, could talk to the BGPS hardware on the train and tell it where it is and the precise time; two things that enable a quick GPS fix via communication with the satellites, and could possibly enable the train to know where it is without the satellites with a good degree of accuracy too.

It all sounds incredibly sensible, so I hope that Nexus put the technology to good use. I'm certainly looking forward to seeing what they do with it.

While I'm talking about the Metro, if there's anyone reading this who is a regular Metro user and has an iPhone, I'd suggest you buy the incredibly useful Next Metro app. It tells you when the next train is due on your route so you know whether you need to run or can just saunter to the station. I hope they bring out an Android version soon!

NEBytes Bytecast

Back in May I posted about starting a podcast with the rest of the guys who run the North East Bytes usergroup - the idea being that we would chat about some things that would be relevant to the folks who attend the NEBytes meetings, i.e. I.T. professionals and software developers working (mainly) with Microsoft products. Relevancy is a fairly subjective thing, but we're covering a fairly broad area from products aimed at corporates, to smartphones and other stuff that's more in the consumer space. It's not all about Microsoft since we're interested in a whole load of related (and less related) technologies.

We've now recorded four episodes, and while I wouldn't say that we've perfected the formula, it's definitely improving. We've increased the speed of editing and releasing, and we've gone from trying to cover everything that we've found remotely interesting to focusing on a few areas. It's so much better that I would suggest you just think of episode 4 as episode 1 and forget that the others actually happened! ;-)

We've also got our act together and sorted our a proper NEBytes Bytecast RSS Feed, so you can subscribe in your favourite podcast client. It's been submitted to iTunes, so hopefully you'll be able to find it there soon too.

[UPDATE] You can now get the NEBytes Bytecast in iTunes.

We're still looking for feedback to improve the show further, so please get in touch and tell us what you think.

Free iPhone 4 cases from MobileFun

[UPDATE] Since Apple have now decided to give away a Bumper or other iPhone 4 case themselves, MobileFun have stopped their free case offer. They'd given away nearly five thousand in the week that the promotion was running - wow!

I mentioned the iPhone 4 reception problems in a previous news roundup post. It seems that Apple aren't going to be giving away free Bumpers to solve the issue, but my friends at MobileFun.co.uk have announced that they are giving away a free iPhone 4 case to cancel out the "death grip" effect.

The free case is like a transparent bumper style band round the sides with cut-outs to access the buttons. It's listed for £7.49, but their blog post has a code to discount that down to zero until the end of July or until stocks run out.

If you want a case that's a bit fancier, then they've got a whole shed load of other iPhone 4 cases to choose from.

iPhone 4 reception problems solved

New and Notable - 25th June 2010

Some of the things that I've found interesting over the last few days...

Windows Live Essentials "Wave 4" beta is out

Some major improvements that I like here. Windows Live Messenger has tabbed conversations, so you don't need a different window open for each person you're chatting with. Windows Live Photo Gallery has a neat facial recognition feature, so you can tag a person in a photo and it'll try to find other instances of that person across your photo collection, and the marvellous Photo Fuse feature (formerly Group Shot).

I found a bug in it pretty quickly when I launched Messenger and got a message saying '%1 wants to be friends.' I checked on the live.com site and of course it wasn't somebody called %1, it was someone with a proper name, who had left a message saying " Hi, I'm [a different name again!] and I have some sexy undies to show you if you visit my site at..." Spammers; meh.

I was quick to turn off the "underline a word if I can add content about it from the web" feature in Messenger. Oh, and one quick tip - if you don't need the whole suite (like the Family Safety feature or Bing Bar), make sure you hit the "Choose the programs you want" link, rather than "Download now", which gives you the lot.

Windows Live Essentials may not be totally essential to everyone, but I recommend it and would suggest you download the beta.

You don't hold it; it holds you!

So the iPhone 4 is out. Demand it high, stock was short, queues were long. I had a chance to see what it felt like in the hand and was suitable impressed with the very, very lovely screen. It's a really nice device and anyone who says otherwise is wrong.

Of course I intentionally held it in my left hand with my palm bridging the two metal strips in the bottom left and I saw what lots of people are up in arms about. It really does drop reception to practically nothing. Apple have acknowledged the issue, with Steve Jobs himself saying "Just avoid holding it that way." Well that's one answer, but it's quite a rubbish one since the whole reason to put the antenna strips on the outside was to improve reception, and that's a fairly natural way to hold the phone.

Now whether this is a mistake, or the reason for Apple selling iPhone 4 Bumpers (glorified rubber bands), I don't know. It seems there are also mutterings of similar issues on older iPhones that have been updated to iOS4, when I'd say it's fairly obvious that the iPhone 4 issue is the design and not the software. We'll just have to wait and see.

Personally I think it's a shame to have to cover up such a pretty device, but I'm also big into function over form too, and you probably want to protect your investment as well as your reception, so you'd best start looking for an iPhone 4 case - there are plenty to choose from.

[UPDATE] I hear a rumour that some people have been offered the official Bumper for free if they complain about the reception problems enough in an Apple Store in the UK. Of course, if that doesn't work, you can just use any old rubber band.

Kinect pricing and Xbox Live Family pack

The price of Kinect for Xbox 360 was one of the things that was really missing from Microsoft's E3 press conference. Several online retailers were listing it at $150 dollars, but nothing was official. Then Microsoft's own online store listed Kinect for $149.99, which left everyone assuming that is indeed the price. I don't think that's necessarily a given, but there's a good chance.

That is higher than I would've liked to see, but if you think about it - you only need one Kinect for multiplayer games, whereas if you wanted motion controlled multiplayer action on the PS3 or Wii, you're potentially going to be buying a bunch of wand and navigation type controllers and those mount up. I have to say that if it is going to be $150, and especially if it's going to be converted to £150 in the UK (which wouldn't be a surprise), I'd like to see a game pack-in. I would also like a lottery win. I'm not sure which is less likely.

If you were wondering, like I was, what's going to happen when your Kinect recognises your face and signs you in to your Xbox Live account, and you're playing an online game, but only one of you has a Gold account and the others are Silver, then wonder no more! Microsoft are releasing the Xbox LIVE Gold Family Pack in conjunction with Kinect's release in November. US pricing is $99 per year - the price of two Gold annual subscriptions - which give you four users.

Sounds like they've done some sensible stuff in terms of the primary user being able to do things like dish out Microsoft Points to the other accounts for them to buy content. The only question I have is how that ties in to my existing Gold account, which, for a variety of reasons, is paid up until January 2012!

The other interesting Kinect news is that (unsurprisingly) it's going to be appearing in use with devices other than the Xbox 360. I want to control my PC by waving my hands at it.

SE help you find and share Android apps

The Android Market for apps is woeful. It may be getting better in newer versions, but there's still no getting around the fact that it's sadly lacking. It's not surprising that 3rd parties are making the effort to help people discover Android apps.

Sony Ericsson are the latest to do this with their Mash-App.com site. People create collections of apps (mash-ups, mash-apps - you see what they've done there?), which can be shared and searched.

Personally, I use AppAware on my phone, which is good for showing what's hot and what's not, but Mash-App may be useful too - it'll depend on the user base. One to watch anyway.

And there's more...

You can hear me chatting about some of these stories and more with Andy and Ben in NEBytes Bytecast episode 3.
