Motorola and Cox Break World Record in Data Transmission Rates
Motorola Mobility recently announced the achievement of a new world record for return path data transmission by using breakthrough technology from Motorola on Cox Communications Las Vegas network infrastructure. Using the ultra low noise, high performance Motorola DOCSIS 3.0 RX48 return path receiver module operating within a Motorola BSR 64000 CMTS Edge Router, the record of 356 Mbps for a 5-85 MHz return path was set by transmitting across twelve return path channels of which six channels employed 256QAM modulation. Typical HFC networks today have two or three upstream channels delivering an aggregate of 40-70 Mbps.
The RX48 and these tests demonstrate that Coxs HFC networks are much more future proof than many have believed, Jay Rolls, senior vice president of technology, Cox Communications. We also increasingly need to be able to segment our business and residential customers, visibility into which is provided by the 5-85 MHz return spectrum utilizing 256QAM. Our networks have the capability to support much higher data speeds than today without the need to replace any of the amplifiers, taps or cables.
