Executive Summary

A spectrum monitoring campaign was launched in an outdoor urban radio environment to investigate the potential deployment of Cognitive Radio (CR) Wi-Fi networks in the 2.4 GHz ISM band. The campaign used a CR learning platform with 4, 8, and 16 sensors. This paper presents Wi-Fi spectrum occupancy and interference behavior based on the outcome of one of the measurements using 16 GPS-synchronized sensors. The authors noted management and data packet redundancies in the current IEEE 802.11 standard causing inefficient spectrum utilization.
