Multiple Resource Unit (MRU) is a new feature in Wi-Fi 7 that builds off another feature first introduced in Wi-Fi 6: Orthogonal Frequency Division Multiple Access, or OFDMA. OFDMA establishes independently modulating subcarriers within frequencies, allowing for simultaneous transmissions to and from multiple clients, which increases throughput and reduces latency. MRU, then, provides enhanced interference mitigation and OFDMA efficiency, further reducing multiple-user latency by another 25%, according to some sources.
By making it possible to selectively puncture overlapping portions of the spectrum, MRU ensures that data travels only on clear frequencies, increasing data rates and reliability in congested Wi-Fi environments.
