The XG1 is the first adaptive, intelligent, software device that truly fits the term, "Cognitive Radio." Its ASAP (Automatic Spectrum Adaptation Protocol) technology manages time, space, frequency and power to provide reliable communications without causing interference to other licensed users.
How It Works
A patent-pending feature allows all XG1 cognitive radios within a network to monitor activity by other users in a specified band and identify unused bandwidth. The network generates a set of parallel carriers and transmits on these channels while they are not in use. When another licensed user is sensed, the network stops using that frequency until it again becomes dormant.
Two additional features are used to further reduce the likelihood of interference to other users. A frequency-hopping technique is used to minimize the amount of time that any single frequency is utilized and the radios' transmit power is dynamically regulated so that the minimum amount of power needed to establish solid communications is used.
