Abstract:
1. A method for associating direction-of-arrival of a wireless transmission with an address of an originator of said wireless transmission, comprising: determining, in conjunction with a first event, by a first wireless communication system, direction-of-arrival of a first incoming wireless transmission arriving from a second wireless communication system at said first wireless communication system via a plurality of antennas belonging to said first wireless communication system; decoding, from said first incoming wireless transmission, in conjunction with a second event, by said first wireless communication system, a first source address associated with said second wireless communication system; detecting, by said first wireless communication system, time proximity between said first event and said second event, thereby associating said direction-of-arrival of said first incoming wireless transmission with said first source address, thereby associating said direction-of-arrival of said first incoming wireless transmission with said second wireless communication system; determining, in conjunction with a third event, by said first wireless communication system, direction-of-arrival of a second incoming wireless transmission arriving from a third wireless communication system at said first wireless communication system via said plurality of antennas; decoding, from said second incoming wireless transmission, in conjunction with a fourth event, by said first wireless communication system, a second source address associated with said third wireless communication system; detecting, by said first wireless communication system, time proximity between said third event and said fourth event, thereby associating said direction-of-arrival of said second incoming wireless transmission with said second source address, thereby associating said direction-of-arrival of said second incoming wireless transmission with said third wireless communication system; recording into a first memory component, by a direction-of-arrival-detector: (i) said direction-of-arrival of said first incoming wireless transmission, together with (ii) a first time-stamp associated with said first event; recording into said first memory component, by said direction-of-arrival-detector: (i) said direction-of-arrival of said second incoming wireless transmission, together with (ii) a third time-stamp associated with said third event; recording into a second memory component, by a receiver: (i) said first source address, together with (ii) a second time-stamp associated with said second event; and recording into said second memory component, by said receiver: (i) said second source address, together with (ii) a fourth time-stamp associated with said fourth event, wherein said determination of said direction-of-arrival of said first incoming wireless transmission and said second incoming wireless transmission is done by said direction-of-arrival-detector and said decoding of said first source address and said second source address is done by said receiver.
