3. The multi-destination transmitter of claim 1 , wherein the transmission handler is to simultaneously transmit the same data to each of the destination devices in the subset of the destination device.
4. The multi-destination transmitter of claim 3 , further including a delay handler to add a delay between the simultaneous transmissions to each of the destination devices in the subset of the destination devices.
5. The multi-destination transmitter of claim 1 , further including a data receiver to receive the data from a media access control layer of a station associated with the multi-destination transmitter.
6. The multi-destination transmitter of claim 1 , further including a training database to store a lookup table of devices and directions to be analyzed by the direction determiner.
7. The multi-destination transmitter of claim 1 , wherein the transmission handler is to transmit the data to the subset of the destination devices via the antennas by simultaneously transmitting first data to a first device of the subset of the destination devices and transmitting second data to a second device of the subset of the destination devices.
8. The multi-destination transmitter of claim 1 , wherein the transmission handler is to transmit the data using a protocol that operates at greater than or equal to 60 gigahertz.
9. A method for multi-destination data transmission, the method comprising:
determining directions for wireless transmission of data to destination devices;
selecting a subset of the destination devices that are associated with different ones of at least one of a plurality of antennas or a plurality of antenna sectors of the plurality of antennas as indicated by the determined directions;
transmitting a first portion of a packet of the data to a subset of the destination devices via the plurality of antennas, wherein the same first portion of the packet is transmitted to each of the subset of the destination devices; and
transmitting a second portion of the packet of the data to the subset of the destination devices via the plurality of antennas, wherein the second portion of the packet is different in each of the transmissions to the subset of the destination devices and includes data received for transmission to the destination devices.
10. The method of claim 9 , further including simultaneously:
transmitting the data to a first device of the subset of the destination devices by beamforming a first transmission in a first direction of the first device determined by the direction determiner; and
transmitting the data to a second device of the subset of the destination devices by beamforming a second transmission in a second direction of the second device determined by the direction determiner.
11. The method of claim 9 , further including simultaneously transmitting the same data to each of the destination devices in the subset of the destination device.
12. The method of claim 11 , further including adding a delay between the simultaneous transmissions to each of the destination devices in the subset of the destination devices.
13. The method of claim 9 , further including receiving the data from a media access control layer of a station transmitting the data.
14. The method of claim 9 , further including storing a lookup table of devices and directions to be analyzed by the direction determiner.
15. The method of claim 9 , wherein the transmitting includes simultaneously transmitting first data to a first device of the subset of the destination devices and transmitting second data to a second device of the subset of the destination devices.
16. The method of claim 9 , wherein the transmitting uses a protocol that operates at greater than or equal to 60 gigahertz.
17. An article of manufacture comprising instructions that, when executed, cause a machine to at least:
determine directions for wireless transmission of data to destination devices;
select a subset of the destination devices that are associated with different ones of at least one of a plurality of antennas or a plurality of antenna sectors of the plurality of antennas as indicated by the determined directions;
transmit a first portion of a packet of the data to a subset of the destination devices via the plurality of antennas, wherein the same first portion of the packet is transmitted to each of the subset of the destination devices; and
transmit a second portion of the packet of the data to the subset of the destination devices via the plurality of antennas, wherein the second portion of the packet is different in each of the transmissions to the subset of the destination devices and includes data received for transmission to the destination devices.
18. The article of manufacture of claim 17 , wherein the instructions, when executed, cause the machine to simultaneously:
transmit the data to a first device of the subset of the destination devices by beamforming a first transmission in a first direction of the first device determined by the direction determiner; and
transmit the data to a second device of the subset of the destination devices by beamforming a second transmission in a second direction of the second device determined by the direction determiner.
