It's not a cellphone. It's basically an backscatter analog audio bug which doesn't even operate on cellphone frequencies, and which has a range of only ~15 metres.
Would they? Those drop out often enough already, without being subject to the vagaries of the local microwave environment in order to power themselves at all.
Don't get me wrong - I love my Rowkin Mini, and a self-charging Bluetooth earbud would be an awesome thing to have! I'm just not sure how realistic a prospect that really is.
of-course this is false marketing, common among university researchers to generate the most buzz. More accurately, this should be called a cordless landline.
Hmm. Think this is a far stretch from being a cellphone prototype. What I'm seeing is a wireless microphone with a number pad prototype.
I get that the implied concept is to take power hungry components and offload them to a nearby transmitter device, but we have that already: a wireless phone.
"The team designed a custom base station to transmit and receive the radio signals. But that technology conceivably could be integrated into standard cellular network infrastructure or Wi-Fi routers now commonly used to make calls."
This is not a cellphone. It is not groundbreaking or new technology. They've made a radio.
