Claim Text:
1. A non-transitory computer readable medium comprising instructions which, when executed by one or more hardware processors, causes performance of operations comprising: receiving a multicast message to be transmitted to a plurality of client devices; determining that a first subset of client devices of the plurality of client devices receive data at similar slowest physical layer transmission rates and that a second subset of client devices of the plurality of client devices receives data at higher than the physical layer transmission rates corresponding to the first subset of client devices, wherein the second subset of client devices comprises client devices in the plurality of client devices that do not belong to the first subset of client devices; selecting the first subset of client devices of the plurality of client devices for focusing a directional radiation pattern by beamforming to the first subset of client devices; transmitting the multicast message using the directional radiation pattern to the first subset of client devices and the second subset of client devices.
