Abstract :
Accurate indoor positioning with minimum dedicated infrastructure is required for certain critical applications such as emergency rescue, fire brigades or incident management. This paper presents an innovative TOA-based ranging technique for IEEE 802.11 networks, which is one of the essential steps towards achieving the desired location technique. Our approach is based on RTT measurements using standard IEEE 802.11 link-layer frames. Due to the noise in the measurements, accurate statistical post-processing is required. Ranging results obtained using the proposed technique show an encouraging achievable accuracy with an error of less than one meter
