Ofcom Asked to Act on 4G TV Interference
Uswitch.com, in a posting by Oliver Folkard, reports Ofcom needs to act on 4G TV interference, says Labour. Helen Goodman, the Shadow Minister for Media, called on Ofcom to clarify is position on the UK's 4G broadband interference problem, which could affect up to two million households. She stated, “At the moment it is unclear whether the government will compensate people affected or expect the industry to do so. There is a real danger that unless urgent action is taken millions of viewers will see their Freeview services disrupted. This would be completely unacceptable.” 
 
 
Techcrunch.com Offers Details on Google Glass Skydive Demo 
On Techcrunch.com Joe Orlin describes How Google Pulled Off Their Live Video Skydiving With Glasses Demo. In case you were wondering how Google got the video from the skydiver back to the ground, this what Orlin reports. “One big technology hurdle was connectivity, which was needed to get the live video signal. It’s not easy to get Internet bandwidth for a skydive nearly a mile up in the air. It’s too high for cell coverage and regular WiFi isn’t reliable enough. Google says their team tried several approaches. They tested using a wok (that’s not the name of a special antenna, they are talking about the cooking tool) with a mifi 4G LTE hotspot connected to it. But that wasn’t used during the live demo. Google hasn’t revealed what their solution was, but they say it was very much cheaper than high-end professional equipment.”
Do any RF Report readers have more information on Google's solution?

I suspect that Google did, indeed use a wok as an antenna, although they would not confirm that this device, known primarily for cooking delicious low calorie dishes, was used not only in the tests, but in the actual run. You might wonder how such a large cooking device as a wok could be used while skydiving. Won't the wind resistance make it difficult, if not actually dangerous? (One hint to make a safer is to ensure that the wok has cooled completely after being removed from the stove.) In fact, there are versions of the wok that would be more practical for the skydiving stunt. There is the higher frequency "mini wok" which is used in some Chinese food carts to prepare a small serving of fried rice. The active part of the 4G antenna is put in the focus of the wok. (This is the location where your egg is most likely to burn when you are making the fried rice, so it should be easy to find, even for the IS guys.) There is another possibility that we could speculate was the type of wok used by Google. That would be the so-called "slow wok." The slow wok is what everyone should take right away when reading one of these press releases from Google.
