Authenticating Devices For RF Communications
First Claim
Patent Images
1. A controller for an RF-capable communications device, comprising:
- a processor arranged for converting the code into a non-RF signal;
a non-RF transmitter arranged for transmitting the code as the non-RF signal for consequent receipt by a second RF-capable communications device;
wherein the received code is arranged for use in authenticating the first device for RF communications with the second device.

29. A controller for an RF-capable communications device, comprising:
-
a non-RF receiver arranged for receiving a code as a non-RF signal from a first source, the code received also by a controller for a second RF-capable communications device from the first source; and a processor arranged for converting the received code from the non-RF signal; wherein the received code is arranged for use in conjunction with the code received by the second device to authenticate the first device with the second device for RF communications. - View Dependent Claims (30, 31, 32, 33, 34, 35, 36, 37, 38, 39)
