The broadband market will be shared by a range of technologies, power line will be the second largest in number of users.
There is a lot of noise on the power line. Our technology can detect noise and overcome it by using other frequencies. We can also place repeaters on the network that will be activated when needed, for example when the microwave is switched on.
The technology Siemens and Nortel developed couldn't deal with the level of noise on power lines. The technical challenge is to deal with the line noise while staying under the regulatory emission level.
In the U.S. on average six to 10 homes are connected to one substation, compared to between 150 and 200 in Europe.
