The system includes a network controller configured to receive and transmit under IEEE 802.11 specifications, and a plurality of directional antennas (17a-17c) coupled to the network base station (16). Each of directional antennas (1 7a- 1 7c) functions as an access point for a respective spatial sector (1 Oa- I Oc). The directional antennas (1 7a10 17c) and the network controller are combined as a single base station apparatus (16) in an exemplary embodiment. Further, an exemplary network controller is configured to concurrently transmit a plurality of the data frames to more than one of the spatial sectors (1 7a- 1 7c), and to synchronize the transmissions in a manner whereby all of the concurrently transmitted frames end simultaneously. 15
