Wireless network apparatus and method for the wireless network apparatus to transmit data

摘要

The wireless network apparatus is electrically connected to a CPU, and comprises a hard-wired computing module and a transmitting module. The CPU executes a driver software to compute a first PLCP length for a first transmission rate, while the wireless network apparatus converts the first PLCP length into a second PLCP length for a second transmission rate through one shift operation and one increment (or decrement) operation executed by the hard-wired computing module. According to the present invention method for transmitting data, the first PLCP length of the first transmission rate is computed first, and the data is then transmitted at the first transmission rate. If the transmission at the first transmission rate fails, the hard-wired computing module will compute the second PLCP length for the second transmission rate based on the first PLCP length, and then the data is transmitted again at the second transmission rate.
