  • Management server, terminal, and method for providing and applying wireless LAN security policy by participating in multiple access points
    Patent number: 12207090
    Abstract: Provided is a method in which a management server provides wireless LAN security policy by participating in multiple APs. The method includes a step of receiving terminal information of a terminal, which is acquired in a process of scanning broadcasting information of multiple APs, from each of the multiple APs, a step of issuing and storing a token for opening a wireless LAN data channel to each of the multiple APs on the basis of reception time points of the terminal information, a step of receiving a token request for opening a wireless LAN data channel to an AP to be accessed, selected by a terminal among the multiple APs, and a step of distributing, to the terminal, a token of the AP to be accessed corresponding to the token request.

  • Method of manufacturing porous sintered reaction-bonded silicon nitride ceramics from granular Si mixture powder and porous sintered reaction-bonded silicon nitride ceramics manufactured thereby
    Patent number: 8808614
    Abstract: Disclosed is a porous sintered reaction-bonded silicon nitride ceramic, which includes an array of sintered granules having fine pore channels in the sintered granules and coarse pore channels formed between the sintered granules, and in which the pore channel size is controlled so that both coarse pores and fine pores are formed together in the ceramic, thus simultaneously enhancing air permeability and capturing efficiency. A method of manufacturing the porous sintered reaction-bonded silicon nitride ceramic is also provided.
