This device appears to use MURS frequencies to allow digital communication between cellphones where there is no connection. goTenna | No service, no problem. And it would allow the phones to be a communications system.
Not quite. Error correction algorithms mean some of the data can get lost and the original datagram can still be reconstructed at the receiving end. Pretty much all modern radio data transmission systems incorporate some form of error correction.If one bit is missing, the data transmission is trash.
No it does not have anything to do with MURS which operates on vhf and nowhere near wi-fi frequencies. It uses the internal wi-fi radio in most cell phones for short range texting.This device appears to use MURS frequencies to allow digital communication between cellphones where there is no connection. goTenna | No service, no problem.

You didn't read the product description at all, did you?It uses the internal wi-fi radio in most cell phones for short range texting.
What is the basis for your claim? I met the GoTenna guys and saw their product just a couple weeks ago. It is MURS according to their founder. The product is going through the device testing and authorization process.No it does not have anything to do with MURS which operates on vhf and nowhere near wi-fi frequencies.

Yep, just goes from one GoTenna to another. Does not access the cell network or internet. Probably not long before someone links one via bluetooth to a PC.When the text is relayed over the MURS where does it go to? Does it go into a cell service or the internet? Or is just from one GoTenna to another GoTenna?
