Satius’s revolutionary Power Line Carrier (PLC) technology includes proprietary coupler and modem designs that overcome line noise, standing waves and the non-linearity problems that historically have limited the usable bandwidth on power lines. Hence, our technology greatly improves the ability of standard home, building or high voltage electrical lines to transmit data, video and voice. This new technology provides a common foundation for all future Satius products.

Satius' power line technology is the only one that can communicate through any size transformers, between all 3 power line phases and through any type of electricity meters without repeaters or any type of installations, up to 3 Gbps. It also meets the new FCC rules.

Currently, Satius’s technology provides high quality analog video and audio transmission, as well as very high speed data communications up to 3 Gbps. We anticipate that continued research and development will result in even higher speeds.

Satius’s technology is inherently reliable, less complicated and provides much higher performance than competitive PLC technologies. Our technology also promises to be a fraction of the cost of alternative wiring solutions, including coax, twisted pair and fiber.



Satius' technology has received three Ben Franklin Innovation Awards from the Ben Franklin Technology Center of Pennsylvania since 1992.

Satius has more then 20 years experience in power line communication, has the most number of licenses related to power line communication and Satius found the solution to the current BPL problems that works between 1.7-80 Mhz. Satius field tested BPL units in several placing in this earth to prove that Satius technology can communicate directly through any size transformers (and between all 3 phases without injecting signals to each power line phases) without any installation on or around the transformers at currently 80 Mbps speed that futures several Gbps and for longer distances than any other BPL technology by meeting the new FCC rules.

THE PROBLEMS RELATED TO BPL WORKING BETWEEN 1.7 to 80 Mhz

1. SPEED -  The communication speed of any device are limited by the bandwidth. Most BPL companies are using frequencies from 2-80 Mhz. Though most of them are operating from 2- 50 Mhz only because the TV broadcasting stations starts at 50 Mhz to 80 Mhz. Between this 2- 50 Mhz specially below 30 Mhz there are lots of licensed radio operators which transmission are still based on analog signal processing. These operators include ARRL, navigation and other radio stations. FCC do not allow BPL transmission on certain frequencies of those. Consequently the allowable bandwidth is small for high speed data transmission for BPL. Furthermore the noise level is high due to too many devices are using these bands. Higher modulation factors can be used to increase speed but those needs higher signal to noise ratio. So, for short distance it is possible to reach higher speed but for longer distance the speed will fall back to the same couple of Mbps or even to couple of hundred Kbps data throughout.

Satius uses high frequencies where RF digital signal processed devices are located some times and therefore Satius can use Ghz of bandwidth consequently reach Gbps speed. The noise level at those Ghz frequencies are much lower then at 30 Mhz.

2. NEW FCC EMISSION RULES FOR BPL  -   The FCC emission requires to measure the emission level on the site, not in the lab. Based on +20 years experience and recent measurements other BPL companies fundamental and harmonics emission can vary as high as 40 dB above the in-site measurements emission levels. The technology other BPL companies are using like the inductive coupler acts like a bad antenna for emission, and do not match the power line characteristic impedance, therefore emission will change in time and location. Harmonics of such system can interfere with the entire RF spectrum. If such BPL operators would decrease its transmit level by 40 dB then it is likely that not even 100 yard distance communication will be achieved by such BPL device and make those devices no longer economical sense to deploy. Furthermore, based on experience if such BPL devices would be deployed on wide scale then it is possible that the (due to incorrect matching) emission such emission levels from each BPL devices could add up time to time and create the bad oscillation or interference device. ARRL reported BPL interferences a mile away from a BPL transmitter at below 30 Mhz. Most European countries still not deploying BPL devices only tested them to find the same conclusion. However, European authorities are open to find a BPL device which emission is stable low with no harmonics and can avoid interference with any other licensed users. If other BPL users (which do not match the power line characteristic impedance at all the time and all location) are shutting down certain band to avoid interference with licensed users usually will not be effective because the harmonics of such un-matched system will create more harmonics which will fill the shut down bands with harmonics.

Satius uses higher frequencies and can meet the new FCC in-site emission measurement rules. Satius emission level is typically 20-40 dB lower the other BPL devices at the same transmit level, and Satius devices do not have harmonics. Furthermore, Satius technology has the uniqueness to match the power line characteristic impedance at any time and any location therefore it can meet the new FCC rules and still provide long distance communication over the power line and through any size transformer. Furthermore, Satius technology can uniquely shut down certain frequency bands by 20-40 dB to avoid RF interferences with licensed users without filling the shut down band with additional harmonics (due to true matching). Higher then 200 Mhz frequencies BPL emission dies out within 100 to couple 100 yards thereby avoiding interferences in the nearby licensed operators.

3. TRANSFORMERS  -  The distribution transformers are an obstacle for other BPL operators below 80 Mhz. Without installing some devices around or next to the transformers such devices can not communicate through all size of transformers. Installing any devices on the mid-voltage power line is not safe and installing devices on all transformers are very un-safe and too expensive.

Satius can communicate through any size transformer without installing any devices on or around the transformer at much higher speed and for longer distances then any other BPL devices.


4. SAFETY - Mid Voltage power lines are a very good receiver for surges and lightnings. Certain areas of the USA where the most market is for BPL, in rural areas, has very high temperatures with low humidity that can cause very high surges even almost every seconds. These surges can even jump the best insulators and blow them up one by one.

Satius uniquely developed a capacitive coupler that matches the power line characteristic impedance at all the time and all locations which can work at such areas that has high surges and lost of strong lightnings. Satius coupler was demonstrated to stand more then 100 KV DC surge/lightning related voltages even continuously.
