Patent ID: 8339984

Claim:
An automatic network retrieval and display device that is connectable to an arbitrary network and that selects a network in a condition of optimal data communications and connects to the network, the automatic network retrieval and display device comprising: a transmission/reception processing unit that receives information on at least one existing network and extracts size information, error information and collision packet occurrence information from the received data; a data conversion processing unit that decides a connection state of each network on the basis of a ratio of a total amount of the error information and the collision packet occurrence information with respect to the size information that are extracted by the transmission/reception processing unit, and outputs a packet information list in descending order of excellence in the connection state; a network monitor processing unit that extracts radio field intensity information from a network identifier existing on the network, creates and outputs a network identification information list in decreasing order of radio field intensity; a network information establishment processing unit that establishes a connection priority based on the communication state of the at least one existing network, on the basis of a combination of the network identification information list outputted by the network monitor processing unit and the packet information list outputted by the data conversion processing unit; a network switch processing unit that is to connect to a network with a high priority on the basis of information of network connection priority established at the network information establishment processing unit; and a display unit that displays a terminal on the network connected by the network switch processing unit.
