FIELD: information technology.SUBSTANCE: apparatus comprises: devices which are connected to the same network and are allocated for the same limited space. A transmitting device is configured to transmit access information for devices in said limited space over a limited-range transmission channel different from the transmission channel(s) of the network control system. In this manner, which substantially limits reception of access information within said limited space, wherein said access information contains an access identifier for obtaining access for controlling one or more devices in said limited space. The transmitting device frequently changes the access identifier contained in the transmitted access information such that only receiving devices receiving an access identifier in the limited space may obtain access to devices in the limited space.EFFECT: faster transmission of information within a network.12 cl, 3 dwg |
