A method for wireless communication and telecommunication in a smart home environment, having the following features: a) a base station is connected to a circuit-switched and/or packet-switched network (LVN, PVN) with an EXTERNAL data source/data sink (E-DQS) for text, audio, video and/or control data (TAVS) assigned thereto for making telephone calls and sending/receiving text, audio, video and/or control data (TAVS), and at least one mobile element (MT, MT1, MT2, MT3, STB, MB, MBK, TKHA) is assigned to the base station for making telephone calls and/or sending/receiving text, audio, video and/or control data (TAVS) via at least one air interface or via at least one air interface and a line interface (LTSS), a1) at least one first mobile element (MT, MT1, STB, MB, MBK) sending/receiving text, audio, video and/or control data (TAVS), the first mobile element (MT, MT1, STB, MB, MBK) and/or the base station being assigned to an INTERNAL data source/data sink (I-DSQ1, I-DSQ2) to send the text, audio, video and/or control data (TAVS) transmitted thereby and to receive the text, audio, video and/or control data (TAVS) to be transmitted thereto, a2) at least one second mobile element (MT, MT2, TKHA) making EXTERNAL telephone calls via the base station or sending to the outside/receiving from the outside the text, audio, video and/or control data (TAVS), and, if more than one second mobile element (MT, MT2, TKHA) is present, also INTERNAL telephone calls being made between the second mobile elements (MT, MT2, TKHA) or the text, audio, video and/or control data (TAVS) being sent/received internally; b) the second mobile element (MT, MT2, TKHA) generates control commands and emits these via the air interface, these control commands being used to address text, audio, video and/or control data (TAVS) terminated in the base station, in the first mobile element (MT, MT1, STB, MB, MBK), in the second mobile element (MT, MT2, TKHA) and/or in the INTERNAL data source/data sink (I-DQS1, I-DQS2), and this data being sent directly or indirectly from the device in which the data is terminated to the INTERNAL data source/data sink (I-DQS1, I-DQS2) or a further INTERNAL data source/sink (I-DQS1, I-DQS2), to the second mobile element (MT, MT2, TKHA) or a further second mobile element (MT, MT2, TKHA) and/or the EXTERNAL data source/data sink (E-DQS) to be output, transferred or externally stored. a) a base station is connected to a circuit-switched and/or packet-switched network (LVN, PVN) with an EXTERNAL data source/data sink (E-DQS) for text, audio, video and/or control data (TAVS) assigned thereto for making telephone calls and sending/receiving text, audio, video and/or control data (TAVS), and at least one mobile element (MT, MT1, MT2, MT3, STB, MB, MBK, TKHA) is assigned to the base station for making telephone calls and/or sending/receiving text, audio, video and/or control data (TAVS) via at least one air interface or via at least one air interface and a line interface (LTSS), a1) at least one first mobile element (MT, MT1, STB, MB, MBK) sending/receiving text, audio, video and/or control data (TAVS), the first mobile element (MT, MT1, STB, MB, MBK) and/or the base station being assigned to an INTERNAL data source/data sink (I-DSQ1, I-DSQ2) to send the text, audio, video and/or control data (TAVS) transmitted thereby and to receive the text, audio, video and/or control data (TAVS) to be transmitted thereto, a2) at least one second mobile element (MT, MT2, TKHA) making EXTERNAL telephone calls via the base station or sending to the outside/receiving from the outside the text, audio, video and/or control data (TAVS), and, if more than one second mobile element (MT, MT2, TKHA) is present, also INTERNAL telephone calls being made between the second mobile elements (MT, MT2, TKHA) or the text, audio, video and/or control data (TAVS) being sent/received internally; a1) at least one first mobile element (MT, MT1, STB, MB, MBK) sending/receiving text, audio, video and/or control data (TAVS), the first mobile element (MT, MT1, STB, MB, MBK) and/or the base station being assigned to an INTERNAL data source/data sink (I-DSQ1, I-DSQ2) to send the text, audio, video and/or control data (TAVS) transmitted thereby and to receive the text, audio, video and/or control data (TAVS) to be transmitted thereto, a2) at least one second mobile element (MT, MT2, TKHA) making EXTERNAL telephone calls via the base station or sending to the outside/receiving from the outside the text, audio, video and/or control data (TAVS), and, if more than one second mobile element (MT, MT2, TKHA) is present, also INTERNAL telephone calls being made between the second mobile elements (MT, MT2, TKHA) or the text, audio, video and/or control data (TAVS) being sent/received internally; b) the second mobile element (MT, MT2, TKHA) generates control commands and emits these via the air interface, these control commands being used to address text, audio, video and/or control data (TAVS) terminated in the base station, in the first mobile element (MT, MT1, STB, MB, MBK), in the second mobile element (MT, MT2, TKHA) and/or in the INTERNAL data source/data sink (I-DQS1, I-DQS2), and this data being sent directly or indirectly from the device in which the data is terminated to the INTERNAL data source/data sink (I-DQS1, I-DQS2) or a further INTERNAL data source/sink (I-DQS1, I-DQS2), to the second mobile element (MT, MT2, TKHA) or a further second mobile element (MT, MT2, TKHA) and/or the EXTERNAL data source/data sink (E-DQS) to be output, transferred or externally stored.
