Abstract

Arrangements for transmitting network credentials from a user device to a second device to enable the second device to connect to a network are disclosed. At the user device, a user inputs network credentials for the second device to enable the second device to connect to a network. The user device transmits modulated light to the second device. The light is modulated so that the transmitted light is encoded with the network credentials. The second device has a photo sensor for receiving the modulated light from the user device and a processor for processing the modulated light to obtain the network credentials from the received modulated light.

Claims

1. A method of transmitting network credentials from a user device to a second device to enable the second device to connect to a network, the method comprising:

at the user device, receiving from a user input of network credentials for the second device to enable the second device to connect to a network; and

transmitting modulated light from the user device to the second device, the light being modulated so that the transmitted light is encoded with the network credentials, the second device having a photo sensor for receiving the modulated light from the user device and a processor for processing the modulated light to obtain the network credentials from the received modulated light.

2. A method according to claim 1, wherein the modulation for modulating the light is frequency shift keying.

3. A method according to claim 1, wherein the modulation for modulating the light is amplitude shift keying.

4. A method according to claim 1, comprising, at the user device, converting the input network credentials to ASCII American Standard Code for Information Interchange or UTF Unicode Transformation Format format, the light being modulated with the ASCII or UTF format network credentials so that the modulated light that is transmitted is transmitted as a binary bit stream of the network credentials.

5. A method according to claim 1, wherein the user device has a keyboard for receiving the input of network credentials by the user typing on the keyboard.

6. A method according to claim 1, wherein the user device has a microphone for receiving an audio input of the network credentials from the user.

7. A user device for transmitting network credentials to a second device to enable the second device to connect to network, the user device comprising:

an input arrangement for enabling a user to input network credentials for a second device to enable the second device to connect to network;

a light source for emitting light; and

a modulator for modulating the emitted light with the network credentials;

whereby a user can input network credentials to the user device and the user device can transmit modulated light to the second device to transmit the network credentials to the second device.

8. A user device according to claim 7, wherein the modulator is arranged to modulate the light using frequency shift keying.

9. A user device according to claim 7, wherein the modulator is arranged to modulate the light using amplitude shift keying.

10. A user device according to claim 7, wherein the user device is constructed and arranged to convert the input network credentials to ASCII American Standard Code for Information Interchange or UTF Unicode Transformation Format format, the modulator being arranged to modulate the light with the ASCII or UTF format network credentials so that the modulated light that is transmitted is transmitted as a binary bit stream of the network credentials.

11. A user device according to claim 7, comprising a keyboard for receiving the input of network credentials by the user typing on the keyboard.

12. A user device according to claim 7, comprising a microphone for receiving an audio input of the network credentials from the user.

13. A device for connection to a network, the device comprising:

a photo sensor for receiving modulated light transmitted by a user device, the light being modulated so that the transmitted light is encoded with the network credentials for the device;

a processor constructed and arranged to process modulated light received at the photo sensor to obtain network credentials from the received modulated light and to connect the device to a network using the network credentials.

14. A computer program for a user device, the computer program comprising instructions such that when the computer program is executed on a user device, the user device is arranged to:

receive from a user input of network credentials for the second device to enable the second device to connect to a network; and

transmit modulated light from the user device to the second device, the light being modulated so that the transmitted light is encoded with the network credentials, the second device having a photo sensor for receiving the modulated light from the user device and a processor for processing the modulated light to obtain the network credentials from the received modulated light.
