With this standard, the modulation type OFDM is used for the first time ever in the cable. What has been standard in other areas for many years (e. g. WiFi, DAB, DVB-T and -T2, LTE) is something fundamentally new for the cable technician.
Also new are the huge bandwidths, which are occupied by the DOCSIS 3.1 signals: A downstream channel can have up to 192 MHz, an upstream channel up to 96 MHz bandwidth! 4,096-QAM with the optional expandability up to 16,384-QAM, data transfer on up to 7,600 subcarriers, a frequency range up to 1,214 MHz with the option up to 1,794 MHz and a new forward error correction (LDPC-BCH) are just a few of the more than impressive parameters of the DOCSIS 3.1 downstream. The upstream is no less innovative. For these reasons, KWS-Electronic will also provide in-depth training and seminars on the new technology.
