Claim Text:
1. A method for communicating data, the method comprising: performing by one or more circuits: transmitting, using a plurality of antennas, only a preamble field of a protocol data unit (PDU) via omnidirectional transmission of signals to a plurality of destination communication devices; determining a location of one of the plurality of destination communication devices based on at least one of a neighborhood map or a signal sent by the one of the plurality of destination communication devices in response to the preamble field; transmitting, using the plurality of antennas, said PDU, which includes another preamble field and a payload, in a direction of the one of the plurality of destination communication devices via directional transmission of signals; and computing a backoff interframe spacing (BaIFS) value based on a maximum size for the payload of the PDU, a minimum data rate for transmitting the payload of the PDU and a maximum transmission opportunity interval time duration.
