3 (Further information relating to clause 3) PLC-Transmitter Technology know how for sale ) THE LICENCE OF THE INVENTIVE HIGH-POWER PLC-TRANSMITTER MODULE FOR SALE PLC=Power Line Communication, 9 khz 30 MHz FIGURE 100. INVENTIVE HIGH-POWER PLC-TRANSMITTER MODULE. CENELEC EN ) Input signal Uin is modulated sinusoidal or square wave voltage. The frequency is e.g. 75, 86, 110, 115, 120 or 132 khz. 2) Ingenious high-power carrier wave amplifier. 3) Inventive band-pass filter. 4) Inventive coupling unit to an electric net, e.g. 400/230V, 50Hz or 200/115, 60Hz. Patent application. INVENTION 4. 5) Znet is the impedance of an electric net at the frequency of the input signal Uin. Net voltage Unet is the output signal voltage upon the net impedance Znet at the frequency of the input signal Uin. Unet = 4 Vpp/1 Ω (4 App max.) 7 Vpp/ 1Ω (7 App max.) depending on the DC supply voltage of the carrier wave amplifier. Inventive high-power PLC-transmitters can be used both in 1-phase and in 3-phase electric power networks. Inventive high-power PLC-transmitter module can be situated inside the PLC-apparatus (one box) or inside the physically separated transmitter remote unit TX/REMU (two boxes: Part 1 and Part 2). In the latter case the transmitted signal, i.e. net voltage Unet, is much higher, e.g. over 10 times higher. See INVENTION 2 (Patent 2): TRANSMITTER WITH A REMOTE UNIT IN AN ELECTRIC NET DATA TRANSMISSION SYSTEM. HomeSafe Finland Oy Pajatie 2, HANKASALMI AS, FINLAND

4 CONCLUSION: During transmitting the rail voltage (signal voltage between phase (L) and zero (N) rails), i.e. net voltage Unet, is much higher (6,6 Vpp. e.g. 110 khz) with invention 2 than without invention 2 (1,4 Vpp 110 khz) in very unfavorable conditions, which means the connecting cable to an electric net (e.g. 115 V. 60Hz) is very long (e.g. Lw=10 m ) and net impedance Znet is very low (e.g. 1 ohm with frequency 110 khz). Invention 2 is useful also at much higher frequencies. It doesn t matter how long signal cable is. INVENTION 2 (Patent 2) can be used both in 1-phase and in 3-phase power networks.

5 SHORT SUMMARY OF THE INVENTIONS 1, 2, 3 AND 4 (9 khz MHz ) INVENTION 1: CONTROL OF DATA TRANSMISSION VOLTAGE LEVEL USING CLIPPING IN A LOW-VOLTAGE NETWORK Invention 1 keeps the output signal voltage amplitude constant at the mains connector (e.g. 230 V, 50 Hz and 200/115 V, 60Hz) of the PLC-device during transmitting, i.e. independent of power line impedance variations. Invention is effective if the connecting cable between the PLC-device and the connecting point of electric net is very short, e.g. under 30 cm. The manufacturing costs of invention 1 are very low. USA-patent and Finnish patent. INVENTION 2: TRANSMITTER WITH A REMOTE UNIT IN AN ELECTRIC NET DATA TRANSMISSION SYSTEM Invention 2 is very effective e.g. in buildings, whose electric net is like a tree. See figures 10 and 20. Strong signal can be achieved along the whole electric network of the building. The more several transmitter remote units (TX/REMU) are used, the higher buildings can be reached. Received signal voltage may be times higher with this invention than without this invention (PRIOR ART). A tremendous remedy. Further invention 1 or invention 3 (ALTERNATIVE 1) can be used to connect the transmitter remote unit (TX/REMU) to an electric net. An extra remedy at the same time. The most effective PLC-patent family in the world relating to coupling the transmitting signal to an electric net without great attenuation. Invention 2 can be used in the frequency range (9 khz 30 MHz ). Interferences may be decrease because the lower output power of transmitter remote units (TX/REMU) is sufficient because of many transmitter remote units (TX/REMU).Only one transmitter remote unit is used simultaneously. Simple and useful invention in practice. Invention 2 increases the transmitting signal e.g times. Manufacturing costs are low, only about 1O EUR per TX/REMU ( ,5 khz, door telephone system). Small case of TX/REMU. Invention 2 can be used in apartment (flat) units and central units. USA-patent and Finnish patent. European patent application. INVENTION 3: METHOD IN AN ELECTRIC NET DATA TRANSMISSION SYSTEM FOR KEEPPING THE SIGNAL LEVEL CONSTANT IN A COUPLING FURNISHED WITH SUPPLY CABLE Invention 3 keeps the signal voltage amplitude constant at L-rails during transmitting thus eliminating the attenuation of the connecting cable and power line impedance variations. Invention 3 is very useful in the buildings, whose electric net is like a tree, star or another type. An excellent invention. Manufacturing costs are low. USA-patent and Finnish patent. European patent application. INVENTION 4: METHOD IN ELECTRIC NET DATA TRANSMISSION SYSTEM TO CONNECT THE TRANSMITTER AND THE RECEIVER TO A THREE-PHASE ELECTRIC NET. Signal magnification is 3 5 in a three-phase electric net. The Finnish patent application is ready but is not yet sent to the Finnish Patent Office. The patent application is secret THE INVENTION FAMILY (Inventions 1 4) is useful also in PLC-devices operating in one apartment, at home or in another restricted area.
