Nexus 4 shown working on Canadian LTE through simple carrier menu code (video)

Want LTE on your new Nexus 4? Well, you might have to move country. Unless it's some elaborate post-Thanksgiving hoax from our Canadian neighbors, several Telus customers have demonstrated that the LTE chip hiding inside the Nexus 4 does work, and have connected to some data speeds resembling a 4G connection. This was enabled through the test menu, accessed by dialing "*#*#4636#*".

Tapping on the preferred network type option, you can select either LTE on its own, or a mix of LTE, GSM and CDMA. According to the videos, the Google phone then taps into your carrier's LTE network if Band 4 is available, and you're good to go. We've so far been unable to replicate it in the UK, which doesn't use the same LTE Band 4 (AWS 2100 / 1700MHz) of Canadian carriers Bell, Rogers and Telus. We have also tested this with AT&T's LTE, but had no luck there either -- we tried it in a Band 17 area, not a Band 4 area (which is less common). This is, however, great news for T-Mobile customers as this is precisely the type of LTE they'll be getting very soon. But for now, there's two working videos already doing the rounds from Canada and we've included them both below.

iPad mini (Verizon LTE): what's changed?

Source: http://www.engadget.com/2012/11/21/ipad-mini-4g-whats-changed/

Well, what's this, then? Another little tablet from Apple? We surprised ourselves by being quite fond of the first iPad mini, which crossed our desks just a few weeks ago. It strikes the perfect blend of size, performance and capability, but without a proper wireless connection its usability on the road is definitely hampered. Thin and light devices like these were meant to come with you when you leave the house, and you shouldn't leave high-speed data behind.

So, we're very glad to now be testing the $459 LTE version of that very tablet, this one Verizon-flavored. It's every bit as thin and very nearly as light as its WiFi-only predecessor but can send and receive your precious (and also your more disposable) data with way more oomph than before. Is such freedom of connectivity worth the $130 price premium? And, just how bad is the hit to battery life? Let's find out, together.

Google brings indoor maps to desktop web browsers

Source: http://www.engadget.com/2012/11/21/google-brings-indoor-maps-to-desktop-web-browsers/

It may not be quite as practical as the mobile version if you find yourself lost in the mall this holiday season, but those looking to plan their shopping route ahead of time can now finally take advantage of Google's indoor maps in their desktop web browser. That new addition, just rolled out today, does come with a bit of a catch, though: the desktop version of indoor maps is only offering the main floor of buildings for the time being, with no word yet on when the ability to view additional levels will be added (something that can currently be done in the Android app). Of course, the availability of indoor maps is still quite a bit more limited than some of Google's other map offerings, but it does now include over 10,000 floor plans in a number of different countries.

Archos' £275 13.3-inch FamilyPad designed to encourage family time

Source: http://www.engadget.com/2012/11/21/archos-familypad/

Three months after we spied the Archos FamilyPad on the FCC, it's finally making its debut just in time for the holiday shopping season. As its name suggests, the 13.3-inch tablet is designed for a whole family to gather around -- though we doubt it would be very comfortable if your family has more than four people. With 10x multitouch support, Archos claims families can use it to watch movies, keep organized, share pictures and play digital board games; the company even pre-installed a few of the latter to get your family started. The FamilyPad doesn't have the best of specs, with a 1,280x800 HD display, 8GB flash memory, a microSD card slot, a 1GHz ARM Cortex A8 CPU, HDMI output and a front and rear camera that are 2-megapixels each. It does run Ice Cream Sandwich and would offer "a variety of email accounts for each family member." Those in the UK can purchase it for £274.99 ($438) when it's available in December, while US residents might have to wait a little longer. Maybe you can give your kids some ChildPads to play on their own instead; they might appreciate it more than enforced togetherness.

Scientists use nanotechnology to harvest electricity from temperature fluctuations

Source: http://www.engadget.com/2012/11/21/thermal-nanotechnology-harvest-electricity/

So far your footsteps, breath and nervous energy have all been tapped to charge up batteries, and now researchers from the Georgia Institute of Technology scientists have pulled it off using thermal changes. They did it with so-called pyroelectric nanogenerators, which use polarization changes to harvest heat energy from temperature fluctuations. Normally output current is too low for commercial electronics, but by making one with lead zirconate titanate (PZT), the team was able to create a device that could charge a Li-ion coin battery to power a green LED for a few seconds. The researchers predict that by doubling the surface area, they could drive wireless sensors or LCDs using only environmental temperature changes from an engine or water pipe, for instance. The result could be green power, but without all that pesky moving around.
