First Claim
1. A wireless communication Access Point (AP) whose security has been enhanced in a physical layer, the wireless communication AP comprising:
- a storage unit that manages channel bandwidth pattern data;
a controller for sequentially acquiring channel bandwidth data from the channel bandwidth pattern data;
a PLL controller for changing a channel bandwidth based on the acquired channel bandwidth data; and
a wireless interface unit for performing wireless communication with a wireless communication terminal using the changed channel bandwidth,wherein the channel bandwidth pattern data is identical to channel bandwidth pattern data stored in the wireless communication terminal, andthe wireless communication terminal and the wireless communication AP are synchronized with each other such that the wireless communication terminal and the wireless communication AP perform wireless communication using the same channel bandwidth.
