| The 802.11az standard (aka Next Generation Positioning (NGP)) builds upon the Fine Timing Measurement (FTM) protocol introduced in IEEE 802.11-2016, enabling Wi-Fi devices to measure the precise round-trip time (RTT) for ranging and positioning. While FTM is currently available in Android 9 (and later) devices - thus enabling the possibility of real testing in Current Off The Shelf (COTS) devices-, it will still take time before the 802.11az can be tested. While some Android 12 (or later) devices can already implement NGP, yet, as of today, there are no NGP access points (APs) available in the market.
NGP enables a Wi-Fi STA to identify its position relative to multiple APs by exchanging high-efficiency (HE) ranging null data packets (NDPs) and recording their time of departure (ToD) or time of arrival (ToA) at the sending or receiving device, respectively. The ToA is estimated using MUSIC super-resolution [1]. This Master Thesis will use the Matlab implementation [2] of NGP, which allows the user to derive the ranging error based on several physical parameters (e.g. SNR, Channel bandwidth, number of transmit/receive antennas, number of space-time streams, etc.). First, the ranging error model in 802.11az must be analysed and then it must be implemented in the NS-3 network simulator, which currently lacks of a direct, built-in support for IEEE 802.11az. The main goal is to simulate and evaluate the performance of 802.11az NGP. Objectives: 1) Derive a ranging error model from the Matlab implementation of 802.11az 2) Implement the ranging error in NS-3 3) Assess a thorough validation of the implementation 4) Perform a thorough assessment of the 802.11az positioning performance REF: [1] Xinrong Li and K.
