AR/VR Spectrum Requirement for Wi-Fi 6E and Beyond

Wi-Fi spectrum scarcity is a challenge for popular wireless applications that require a high data rate, low latency, and high reliability in different environments. AR/VR applications for e-education in a school is a good example of a challenging scenario where a large number of AR/VR devices have high data rate and latency-sensitive traffic, and require reliable wireless connectivity. In order to accommodate such emerging applications, several leading countries including the USA, South-Korea, Brazil and Canada released 1200 MHz of the spectrum in the 6 GHz band for the unlicensed use cases. Other countries, including European Union member states, only released the lower 500 MHz of the 6 GHz band and have yet to decide on the future use of the upper 6 GHz band. In this paper, we quantify the impact of spectrum scarcity on the feasibility of the AR/VR applications for e-education. Practically, we compare the maximum number of AR/VR devices supported in each classroom of a given school, depending on whether 500 MHz or 1200 MHz are available for unlicensed use cases.
