Abstract
Its prominent position as non-line of sight RAT for data communications in small cells, along with its continuous evolution, make the IEEE 802.11 family of standards a good candidate to play a key role in future 5G deployments. Considering the latest advances in the physical layer (i.e. aggressive modulations up to 1024-QAM, MIMO, etc.), Wi-Fi is ready to offer throughput in the Gbps scale, which will surely grant it a place among the most widespread 5G RATs. The evolution towards 5G RAN brings new challenges in terms of time synchronisation requirements imposed to radio transmissions. To achieve such accuracy in the transport of timing, the expectation is to continue relying on a mix of centralised or distributed Global Navigation Satellite Service (GNSS) receivers networked towards the synchronisation clients through packet-based timing transport such as IEEE 1588 PTP. This has been the conventional approach due to inviable costs of deploying GNSS receivers in every base station, especially when considering indoor equipment.
