Method for setting up a local broadband network, comprising the following steps: - an electronic system determines a geographical location of the electronic system, - dependent on the location, the electronic system selects an external function in the broadband network and - the electronic system follows a communications protocol of the broadband network depending on the external function wherein, depending on the selected external function, the electronic system functions as i. a repeater, ii. a base station, preferably having multiprovider capability iii. a switch, iv. a hub, v. a gateway, vi. an access point or vii. a communications terminal, characterised by the following features: - the electronic system measures an actual state of the broadband network at the location defined by the frequency bands used in the surrounding area and the particular strength of the signals acquired in the latter, the upload and download speeds as well as environmental health-related limits (16, 17) for permitted radiation levels, - the selection of the external function also depends on the actual state and - the electronic system reports at least the location and the external function by a common communications backbone to a central database. - an electronic system determines a geographical location of the electronic system, - dependent on the location, the electronic system selects an external function in the broadband network and - the electronic system follows a communications protocol of the broadband network depending on the external function wherein, depending on the selected external function, the electronic system functions as i. a repeater, ii. a base station, preferably having multiprovider capability iii. a switch, iv. a hub, v. a gateway, vi. an access point or vii. a communications terminal, characterised by the following features: - the electronic system measures an actual state of the broadband network at the location defined by the frequency bands used in the surrounding area and the particular strength of the signals acquired in the latter, the upload and download speeds as well as environmental health-related limits (16, 17) for permitted radiation levels, - the selection of the external function also depends on the actual state and - the electronic system reports at least the location and the external function by a common communications backbone to a central database. i. a repeater, ii. a base station, preferably having multiprovider capability iii. a switch, iv. a hub, v. a gateway, vi. an access point or vii. a communications terminal, characterised by the following features: - the electronic system measures an actual state of the broadband network at the location defined by the frequency bands used in the surrounding area and the particular strength of the signals acquired in the latter, the upload and download speeds as well as environmental health-related limits (16, 17) for permitted radiation levels, - the selection of the external function also depends on the actual state and - the electronic system reports at least the location and the external function by a common communications backbone to a central database. - the electronic system measures an actual state of the broadband network at the location defined by the frequency bands used in the surrounding area and the particular strength of the signals acquired in the latter, the upload and download speeds as well as environmental health-related limits (16, 17) for permitted radiation levels, - the selection of the external function also depends on the actual state and - the electronic system reports at least the location and the external function by a common communications backbone to a central database.
