Oakland police force AT&T to disable 2G towers

Lately, the Oakland Police Department has been having some issues with its brand new $18 million radio system. Apparently, the police have discovered the cause of all this interference, and it seems that 2G cell phone towers owned by AT&T are at least partially to blame. Obviously, having police officers who can't communicate with one another or with firefighters is no good, and AT&T has been forced to partially disable 16 of its towers as result.

Google gets patents from IBM, including “computer phone”

In the great IP wars of the early 21st century, patents are bought and sold like AK-47s on the black market. And to extend the metaphor, Google just picked up a payload that might prove to be very effective indeed. The company has acquired 188 patents outright with another 29 patents pending being transferred to Google. The most interesting among them is a patent on the "computer phone", issued way back in 1987.

Wysips Solar-Powered Screen Cover to Add $1 to Smartphone price [ALPHA]

There are more details coming out over the Wysips Solar Powered screen for smartphones we reported on last week. According to this hands on, done by Laptop Magazine, the photovoltaic screen will be included in new smartphones within a year and promises to only add about $1 to existing cellphone prices. The hands on shows a smartphone mockup with an amp-meter attached to it, showing the fluctuating voltage as the device moves in and out of exposed light. Wysips also says that the solar film isn't only being developed for for smartphones, it'll have applications for tablets and eBook readers as well.

Touchscreens may do double duty as solar panels

French company Wysips is working on a new technology which would cause smartphone touchscreens to do double duty as solar panels to recharge phones. The concept is quite interesting as it involves laying an ultra thin transparent photovoltaic film layer on top of the cellphone display screen. The film would capture energy not only from the sun, but any nearby light source. Projected recharge times would be about six hours from direct sunlight and a few hours longer from leaching energy from indoor lights. Wysips is already at work on the second generation of the technology, which looks to provide 30 minutes of talk time after just an hour in the sun.

Inventor of the cell phone gave up his iPhone for a Motorola Droid

Most of us don't know who Martin Cooper is, he was the first person to make a call on a handheld cell phone prototype in 1973 and he is named on the patent “radio telephone system” filed that same year. Android now has some strong endorsers in the inventor of Linux and now the inventor of cellphones.
