Maximal Ratio Combining (MRC) is a feature that enhances the reception quality of signals in wireless networks, particularly beneficial in multiple antenna setups. It allows for improved signal processing by combining multiple received signals in a way that maximizes the overall signal quality. However, 1X1:1 low-end client devices are typically limited to a single antenna. Because MRC relies on the use of multiple antennas to perform its signal processing functions effectively, it cannot be implemented in these low-end devices, which lack the necessary hardware configuration.

In contrast, the other advantages mentioned—channel bonding, MCS (Modulation and Coding Scheme) data rates, and mandatory data rates—are applicable to devices with single antennas, allowing them to take advantage of higher data throughput or at least operate within defined performance boundaries, despite the limitations of their hardware. Thus, while channel bonding and MCS data rates can enhance the performance of low-end devices, and mandatory data rates define the minimum performance standards that all devices must adhere to, Maximal Ratio Combining remains inapplicable due to the absence of multiple antennas in 1X1:1 configurations.
