On LTE Roaming …

The IP eXchange (IPX) is used for data when the users roam between different networks. GPRS Roaming eXchange (GRX) is a service within IPX. One of the main areas of discussion within the LTE World Summit 2012 in the Signalling Focus day was roaming on LTE. Different vendors have different proposals and solutions; couple of them are as follows:
Interesting to see that iBasis has proposed LTE Signalling eXchange (LSX) as a way forward.
A presentation from Acme Packet (for an earlier conference) has interesting VoLTE roaming options proposal.

Finally, while everyone was focussing on LTE-LTE roaming, only Diametriq was looking at LTE-LTE/3G/2G Roaming. The relevant part of their presentation is embedded below.

Sony Xperia Advance Announced

Most phones built for rugged duty tend to look like bloated children’s toys.  That’s why we appreciate rugged phones that actually manage to look a little like regular phones.  The Sony Xperia Advance definitely plays the part well.
Unlike many rugged phones, this isn’t some dumb feature phone with some basic talents.  Instead, it’s a full-fledged [...]

Keep track of your valuables with Nokia Treasure Tag

Today, Nokia has announced Treasure Tag to help you keep track of valuable things like your car keys, wallet, or even your bag. Treasure Tag is a small 30 x 30 x 10mm device that gets paired to your Lumia Windows Phone via NFC or Bluetooth. Once you do that, you’ll be asked to download the Nokia Treasure Tag app from the Windows Phone Store. Once you get out of range of whatever you have “tagged”, both your Lumia Windows Phone and the Treasure Tag will emit a loud tone to alert you. If you miss an alert, you can use the Nokia Treasure Tag app to locate what you’ve lost on a map, powered by HERE. Cool, huh?


You can have up to four different Treasure Tags connected to your Lumia Windows Phone at any given time. And you can assign icons or photos to these Treasure Tags and pin them to your Start screen as they have Live Tiles and are colored to match the Treasure Tag. If for some reason you need to deactivate a Treasure Tag (let’s say you left your bag at home), you can by a long press on the Treasure Tag. You can also mute the alarm or put it into sleep mode from within the Nokia Treasure Tag app.

Oh and each Nokia Treasure Tag has up to six months of battery life which is replaceable.

For more on Nokia Treasure Tag, read this blog post from Nokia Conversations.

Nokia Treasure Tag is expected to be available at retailers globally in April for a recommended retail price of about $29.90 (U.S.) or €24,90. They will be available in four different colors: cyan, yellow, white and black. Nokia Treasure Tag will work with Lumia Windows Phones hat have the Lumia Black update.

I will be buying 4 yellow Nokia Treasure Tags promptly when they become available! What about you?

New and Updated Bing Apps for Windows Phone

Today, the Bing Team is announcing a comprehensive update for their existing Bing apps on Windows Phone (Bing News, Bing Finance, Bing Weather, and Bing Sports) and introducing 3 brand new apps: Bing Food & Drink, Bing Health & Fitness, and Bing Travel. Along with fresh features, your personalized content from all 7 of the Bing apps will now roam across all your Windows devices (Windows PCs and Tablets running Windows 8.1). For example: any places you’ve added in the Bing Weather app will now roam and sync between your Windows PC or Tablet and your Windows Phone! Just set up once with your Microsoft Account, and you’re all set.

You can get a deep-dive on all the new and updated Bing apps from Brian MacDonald in this blog post over on the Bing Blog. However, I’ll summarize a little bit of the awesomeness:


Bing Food & Drink (New!): With access to over 600,000 recipes from leading culinary content partners like AllRecipes, BigOven, Epicurious, Bon Appetit, Saveur, Food52 and more – you can now find the perfect recipe right on your Windows Phone. You can also easily create and manage your shopping lists based on a recipe you find or your weekly grocery list. Your favorite recipes and shopping lists will roam across all your Windows devices.

5 GPSTracker

Bing Health & Fitness (New!): You get access to nutrition, fitness and medical information, hundreds of workouts and tools that can be personalized to fit you specific needs and help you stay healthy. You also get 3 trackers – Diet Tracker, Cardio Tracker and GPS Tracker – to gather information about your activities and nutrition to make healthier decisions.

2 Flights

Bing Travel (New!): Plan and manage your next trip right on your Windows Phone. You can use the Bing Travel app to find all kinds of places with destination guides, rich photos and more. You can plan your trip and book your flights and hotels. And you can pin your flights right to your Start screen on your Windows Phone.


Bing Finance (Updated!): We are introducing ‘My Finance’ on your Windows Phone that allows you to securely track your brokerage accounts in the Bing Finance app, including monitoring account balances, portfolio distribution, holdings transactions and more. This works for folks in the U.S. who have brokerage accounts with E*TRADE, Fidelity, Fidelity NetBenefits, Sharebuilder, Charles Schwab and TD Ameritrade.


Bing Sports (Updated!): Bing Sports on Windows Phone lets you watch live event coverage for NBA, NFL and all major soccer leagues. You also get player profiles that includes news stories, photos and social media updates. And you can personalize Bing Sports for your favorite teams which will roam across your Windows devices.


Bing News (Updated!): New sources have been added including the Wall Street Journal and The New York Times. You can customize your sources and have them roam across your Windows devices. And a much requested feature – the ability to share articles of interest via text, email or on your social network has been enabled!

A day does not go by where I don’t use the Bing apps on my Windows devices. It is great to see the 3 new Bing apps for my Windows Phone and that all the apps roam and sync together across all my Windows devices! Grab the Bing apps today from the Windows Phone Store!

Hitting the road? Nokia’s HERE map and navigation apps have new features, work on more Windows Phone 8 models

With summer travel season in full swing, mapping and navigation apps are getting a big workout on many people’s smartphones. One bit of Windows Phone app news overshadowed by last week’s big Nokia Lumia 1020 unveil was that the company’s trio of free travel apps—HERE Drive, HERE Transit and HERE Maps—each received a nice update. More importantly, they’re also now available for all Windows Phone 8 smartphones.

On its blog, Nokia said last week that the apps got a face lift and, in several cases, some handy new features. The rundown:

HERE Drive/Drive+

2 of 84 of 8

HERE Drive now shows real-time traffic information around your area and adds a feature called My Commute, which provides the estimated travel time to the office right on the app’s Live Tile, so you know whether you have time to grab coffee or need to head out early. While you’re driving, My Commute continues to monitor traffic and lets you know if any unexpected hiccups have occurred or a better route is available. (Curious how real-time traffic works? The Nokia Conversations blog had an interesting behind-the-scenes post about it recently.)

HERE Drive+, the premium version of the app, also adds the ability to navigate in offline mode without a SIM card. HERE Drive+ is pre-loaded and available for free on select Nokia Lumias, and comes as a paid upgrade for other Windows Phone 8 models (more details here). HERE Drive+ is an especially good option for international travelers since the app has a global navigation license for all 95 supported countries.

HERE Maps adds transit station details and the ability to pause LiveSight augmented reality scenes for easier exploration.

HERE Transit

HERE Transit combines schedules and route details for bus, train, subway, ferries and more in one handy place has been redesigned to make it easier to create and quickly access favorites.
