NETWORK MANAGEMENT SYSTEM

PROBLEM TO BE SOLVED: To improve security remarkably, without impairing network advantages. SOLUTION: A waveguide sheet 6 functioning as a radio antenna of a LAN is arranged at many tables 1, 3 and 4. The waveguide sheet 6 is connected to a server 12 via a connector 8 and the repeater 11. A floor used by many waveguide sheets 6 are divided into a manager area 15, a general area 16 and a business negotiation area 17, and the respective areas 15, 16 and 17, with each having the hardness or ease of access to a network. The general area 16 and the business negotiation area 17 cannot be accessed to specific information of the network, regardless of the existence/absence of the authentication of a personal computer P. High security which is not conventionally available can be secured, because a person must go to a seat in the manager area and use an authorized personal computer, in order to access the specific information.
