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.
