摘要： A concentrator (11) coupled to a wired network (13) also acts as a master device relative to each of a plurality of ad hoc wireless communication networks (15), thereby permitting wireless communication devices in the ad hoc networks to access the wired network. The concentrator utilizes antenna array processing and beamforming techniques when communicating with the devices of the various networks, in order to advantageously reduce communication interference between the networks.

摘要： A probe, listen and select (PLS) technique can be used to select from an available frequency spectrum a frequency band whose communication quality is suitable for wireless communication at a desired rate. Probe packets can be transmitted on different frequencies (223) during a known period of time (TPLS), and frequency channel quality information can be obtained (225) from the probe packets. This quality information can then be used to select a desirable frequency band (227). The communication quality of the selected band can also be used as basis for selecting (141) from among a plurality of modulation and coding combinations that are available for use in communications operations.

摘要： In packet communications, one existing address code in a predetermined address field (AM_ADDR) of a packet can be used to indicate that bits in another field (TYPE) of the packet represent additional address information. Additional address information can also be provided for by extending the length of the predetermined address field.

摘要： The frequency hopping pattern of a first wireless communication device is modified such that each transmission (73) to a second wireless communication device is on a frequency (MSj+1) that the second device's normal frequency hopping pattern specifies for one of the second device's next several transmissions to the first device. This permits the second device to make quality measurements (54) on a frequency that the second device will soon use (51) for transmission to the first device.
