It’s obvious to assume that your henpecking on a wireless keyboard could be intercepted by a RF-snooping ne’er-do-well, but what about your wired or laptop keyboard—that should be safe, right? Nope. Researchers at Lausanne, Switzerland’s Security and Cryptography Laboratory (part of the EPFL school) have demonstrated here that 12 different keyboards, bought from 2001 until now, can be eavesdropped upon by monitoring their electromagnetic signatures—wirelessly, from up to 65 feet away, through walls.
.
This second video demonstrates the second set of their experiments. The researchers devised four separate methods for EM eavesdropping, which will be detailed in specifics in a paper to be released after peer review. The method for intercepting signals involves detecting the full spectrum of electromagnetic radiation emitted by a keyboard (which are unshielded to keep costs and form factors down), and analyzing the specific change in signal over a variety of wavelengths for each key press. All the more reason to work/live in a giant Farraday cage.

Discussions are again resurfacing about which technology should be used to improve coverage; Femtocells or UMA. Honestly, I have not been a big supporter of UMA (and you dont have to agree with me) and earlier this year when Nokia raised doubts about the technology, i stopped following it completely. Kineto has been the biggest supporter of UMA and is still carrying the torch.
Kineto recently
received over $15 million in investment from Motorola that it plans to use to increase its reach in UMA. Last month it had received
investment from NEC. One of the reasons for the resurgence could be because the UMA technology has matured since being used for some time. T-Mobile has already rolled
Hotspot @ Home using UMA. Also more phones are now available supporting UMA.
One of the drawbacks that will always be present in case of UMA is that special handsets will be required that would support WiFi as
UMA is based on 802.11. This means more expensive phones and higher consumption of power leading to smaller battery lives. One more problem with UMA is the interference due to other
ISM band devices and there are many technologies like Bluetooth, etc that are competing for the band.
The
drawback in case of Femtocells could be that their price is still quite high as complete Node B + RNC functionality is generally available in a
Femtocell and at the same time all the aspects have not yet been standardised. Along with these,
Femtocells that use the same spectrum as that of the operator can cause interference with the
Macro cell. This would in turn require very clever management of spectrum frequencies, etc.
A possible long term solution could be (but I dont see anyone agreeing to it right now) that phones with UMA technology become more common and a combined UMA +
Femtocell equipment is rolled out by the operator. At the end user premises, depending on the strength of rf reception, the equipment can either use UMA or normal
Femtocell functionality. If this idea is agreed upon, then there would still be couple of years before all interworking and other technological problems are ironed out.
