Abstract

The current options for wireless communication have changed the way people work and the way in which networks can be deployed. However, there remains unresolved problems in the setup and configuration of wireless communication links. Both known cellular and ad hoc wireless networking protocols and systems are deficient in that the ability for users to communicate without a priori knowledge of MAC addresses (represented by phone numbers, IP addresses and the like) is limited or may be compromised in a hostile environment. In contrast, provided by aspects of the present invention are devices, systems and methods for establishing ad hoc wireless communication between users that do not necessarily have MAC addresses and the like for one another. In some embodiments, a first user visually selects a second user and points a coherent light beam at an electronic device employed by the second user. Data specific to the first user is modulated on the coherent light beam, which can then be demodulated when the coherent light beam is received by the electronic device of the second user.

Claims

1. A system for remotely establishing data communication between a first device and a second device, the system comprising:

a device interface, the device interface having a first output and a first input, wherein the first output is connectable to a camera mount controller to provide a control signal for directing the operation of the camera mount controller, and wherein the first input is connectable to receive a data input from a remote first user;

an optical modem for transmitting data on a coherent light beam in a direction that is selectable with the first device;

a memory for storing data within the first device; and

a controller connectable to the optical modem, the memory and the data interface, the controller having computer usable program code for transmitting data from the first device to the second device, the computer usable program code including program instructions for;

parsing signals received by the first device through the device interface;

determining whether a signal received is for directing the operation of the camera mount controller or initiating communication with the second device;

if the signal received is for directing the operation of the camera mount controller, transmitting a control signal for directing the operation of a camera mount controller; and

if the signal received is for initiating communication with the second device, modulating selected data onto a coherent light beam with the optical modem wherein the selected data identifies the first device sufficiently to permit communication between the second device and the first device using a means other than the coherent light beam;

wherein the second device is configured to be able to use the selected data to carry out at least one action selected from the group consisting of;

communicate with the first device using a means other than the coherent light beam, ignore the first device, and block further transmissions from the first device.

2. A system according to claim 1, wherein the computer usable program code further comprises:

initially transmitting an unmodulated coherent light beam for a first duration to allow a user to aim the coherent light at the second device;

and transmitting the selected data from the optical modem after the first duration.

3. A system according to claim 1, wherein the selected data modulated onto the coherent light beam is one of a text message, a phone number, an email address, a Media access Control (MAC) address suitable for a wireless communication link and a wireless session identifier.

4. A system according to claim 1, further comprising a camera, the camera having a network connection to provide real-time video data to a user through the network connection.

5. A system according to claim 4, wherein the camera is further connectable to receive data signals from the network connection.

6. A system according to claim 5, wherein the network connection is one of an ethernet connection, a USB (Universal Serial Bus) port and a wireless modem.

7. A system according to claim 6, wherein the camera is integral with the device and internally connectable to the device interface.

8. A system according to claim 4, further comprising a camera mount controller serving as an interface for a mechanical system for positioning the device so as to direct the field of view of the camera and a coherent light beam transmitted from the optical modem, wherein the path of the coherent light beam represents a data path between the device and a target selected by the user.

9. A system according to claim 8, further comprising a movable camera mount serving as the mechanical system for positioning the device.
