Abstract
A wireless router applying an antenna control method includes a number of antennas and communicates with a number of terminal devices via the antennas. The antenna control method includes detecting a current bandwidth Bcur of each terminal device communicating with the wireless router and determining a maximum bandwidth Bmax of each of the terminal devices, computing a weighted sum SUMB of the bandwidths of the terminal devices according to the detected current bandwidth Bcur and the maximum bandwidth Bmax of each terminal device, comparing the weighted sum SUMB of the bandwidths with a first preset value, and turning on or turning off at least one of the antennas according to the compared result. A wireless router is also provided.
Claims10
A wireless router communicating with a plurality of terminal devices, the wireless router comprising first antennas, second antennas, a memory, a processor, and an antenna control system, wherein the first antennas are currently in an off state, wherein the second antennas are currently in an on state, wherein the antenna control system comprises computerized codes in the form of one or more programs stored in the memory and executed by the processor, wherein the one or more programs comprises:
- a bandwidth detecting module having detecting program codes causing the processor to detect a current bandwidth Bcur of each of the plurality of the terminal devices communicating with the wireless router, and determine a maximum bandwidth Bmax of each of the plurality of the terminal devices;
- a computing module having computing program codes causing the processor to compute a weighted sum SUMB of bandwidths of all of the plurality of the terminal devices according to the detected current bandwidth Bcur and the maximum bandwidth Bmax of each of the plurality of the terminal devices, and obtain a compared result by comparing the weighted sum SUMB of the bandwidths with a first preset value;
- and
- a control module having controlling program codes causing the processor to turn on at least one of the first antennas or turn off at least one of the second antennas according to the compared result.
