Abstract:
1. A method for adjusting transmission power of a communication system having a first terminal and a second terminal, the method comprising steps of: repeatedly transmitting a detecting packet from the first terminal to the second terminal by sequentially using one of a variety of transmission powers based on a table containing plural groups of transmission information, each group of which comprises a transmission power and a transmission rate; receiving a responding packet from the second terminal, wherein the responding packet corresponds to the one of the variety of transmission powers; choosing at least one from the variety of the transmission powers for transmitting at least a data packet to the second terminal therewith based on the responding packet from the second terminal; obtaining a statistical value based on the responding packet from the second terminal and analyzing the statistical value to update the table, wherein the first terminal performs a message transmission to the second terminal via a protocol complying with an IEEE 802.11 standard; and updating the table based on the responding packet from the second terminal, wherein the updating comprises omitting at least one of the groups from the table for a next time interval.
