New Radio over Coax
Charter, Rogers Communications, and CableLabs have collaborated on a new technology they are calling new radio over coax. The immediate goal of the new technology is to use a cable company’s coaxial network to transmit 5G signals. In Charter’s case, the company wants to use new bandwidth to take advantage of Charter’s CBRS spectrum. The technology to make this happen relies on opening up new spectrum inside the HFC (Hybrid fiber coaxial) network at frequencies higher than 1.8 GHz, which is the current bandwidth needed to implement DOCSIS 4.0.
