License authentication method in wireless access point, wireless access point apparatus performing said license authentication, license activation method in client apparatus, and client apparatus interworking with wireless access point

A wireless access point apparatus performing license authentication, comprising:

• a non-transitory storage memory;
• a processor;
• the non-transitory storage memory storing executable instructions that when executed by the processor cause the process to perform functions of:
• receiving a license authentication request including license information from a client;
• calculating a distance of the client from the wireless access point in response to the received license authentication request;
• based on the calculated distance, determining whether the client exists within a range of allowed positions for license authentication related to license location information for allowing authentication of a license included in the license information;
• wherein whether the client exists within the range of allowed positions for license authentication is determined by comparing:
• a first distance value which is a distance from the wireless access point to a position corresponding to the license location information with a second distance value which is a distance from the wireless access point to the client;
• comparing a distance difference between the first distance value and the second distance value with a threshold value;
• and if the distance difference is smaller than the threshold value, determining that the client exists within the range of allowed positions for license authentication;
• and
• determining whether to authenticate in response to the license authentication request based on the determining that the client exists within the range of allowed positions for license authentication.
