Startup GoTenna has launched its eponymously named device, which lets users communicate without the need for a cell tower. "This is an interesting concept," said tech analyst Jim McGregor. "It's like a walkie-talkie on steroids." The device uses BlueTooth LE to pair with a user's smartphone. It can exchange text messages only with another GoTenna. The GoTenna's use is further limited because it encrypts messages with the RSA 1024 public/private key encryption, which means only a GoTenna that has the decryption key can read the message.GoTenna Makes Wireless 'Magic'
