Due to the high competitive pressure and the strong demand for ever faster Internet, the cable network operators would like to introduce the new DOCSIS 3.1 technology - which enables exactly this.

Unfortunately, DOSCIC 3.1 has the major disadvantage that below about 250 MHz, broadcast services such as FM or DAB cannot be broadcasted over the cable network (CATV) anymore. Both are technically incompatible.

A switch-off of FM means that cable network operators would lose many of their most loyal customers. Reducing their loyal customer base is the last thing cable network operators need in a tight competitive environment. FM radio programs have been broadcasted over cable for decades and have been a standard on a good cable network.

Sumatronic has been working for 30 years with the broadcasting of radio programs and has studied the situation. This small Swiss company has now developed a ready-to-use solution that allows both: The introduction of DOCSIS 3.1 and - at the same time - enables FM or DAB / DAB + distribution over cable networks with economically measures.

The solution is called DOCSIS+FM, resp. DOCSIS + DAB (PCT patent pending).
The system also works for HD Radio (U.S.) or DMB (South Korea) and can be adapted to other broadcast services.

A device in the head-end of the cable network and an adapter in front of the subscriber's FM or DAB-receiver are sufficient.

This will enable the cable networks to catch up in the competition and at the same time to serve all existing customers who have been receiving FM or DAB cables for years or even decades. This will continue to be possible even after the FM transmitters will be switched off.

The cable connection thus remains the simplest and most reliable way for customers to provide their existing receivers with a good antenna signal and to easily receive a large number of radio programs. Exactly this important advantage other networks do not have.

Thus, there is no reason to push the population to buy new equipment. Customers can decide for themselves if and when to choose a different technology for reception of radio-broadcasts and a huge amount of electronic waste is spared us all.
