A Femtocell is a small box that plugs into your internet router & provides 3G phone coverage in poor reception areas.

The Register has just done a round-up of the Femtocells currently available for UK users. It’s worth a read.

Vodafone are still the only network selling the Sure Signal boxes to anyone who wants one for £100 each. Although other providers will apparently suppply a free box if you threaten to leave.

italian supreme court affirms workers tumor risk link from wireless mobile phones

From today’s Microwave News bulletin:

Many of you may have already heard that the Italian
Supreme Court has affirmed a worker’s compensation
claim filed by a man who developed a tumor after using
wireless phones daily for 12 years. This is the first time
a court has ruled in favor of such a link.

The decision may turn out to be an important
legal precedent, but it also represents a defeat for
a small coterie of experts on ICNIRP and at the
Karolinska Institute in Stockholm whose
“don’t worry, be happy” outlook was rejected by the court.

Video of Motorla C123 Calypso mobile phone acting as a GSM base station

Video of Motorla C123 Calypso mobile phone acting as a GSM base station.

I missed this when it was first released, but here’s Sylvain Munaut demonstrating a cheap Motorola Calypso phone (C115, C118, C123 etc) acting like a GSM base station.

Doesn’t have enough bandwidth for voice calls, but can send control signals & SMS. Amazing piece of hacking.

I’ll take the Faraday Cage Carriage on this train please

Article in the New Scientist today – 1 September 2012 on page 18.

‘Joined-up power people’ advocates using the latent power of smartphones to power cluster computing tasks, but then points out that the combined processing power is piss-poor compared to a regular desktop PC. The problem with this superb hypothesis is that processor cycles used on a phone eat battery power, and idle time doesn’t. DUH!

They do mention that all the phones in a train carriage could combine over WiFi to perform a useful task. Presumably this useful task is to annoy an electro-sensitive person?

If you’re going to use your phone/laptop over free WiFi on a train, make sure you also use a secure proxy (hidemyass) or use a 3G Modem dongle instead – that way your Facebook account won’t get vandalised!
