Abstract
Described herein is a device to be used in a wireless communication system with CSMA-based MAC, comprising a mechanism for transmitting at least a first and second Request-to-Send (RTS) messages and at least first and second data packets on a transmission medium, and a spatially selective antenna. In one aspect, the device uses a distributed antenna that combines the antenna elements of several devices and the device observes the transmissions of other devices, analyzes the observed transmissions for transmission patterns and adapts its own transmissions to the detected transmission patterns. Also described is a corresponding system, method and computer program to be used in a wireless communication system.
