In addition to establishing the world record at 5-85 MHz, a maximum transmission rate of 141 Mbps was also achieved over a 5-42 MHz return path using six return path channels. Three of these channels were able to operate using 256 QAM modulation, as opposed to 64 QAM maximum in use today, which is also believed to be a record. For the first time, cable operators can use the 5-42 return path to provide 100 Mbps dedicated to business customers and simultaneously provide residential customers with the return path bandwidth necessary to meet their growing needs.
About the RX48:
The RX48 provides between 33% and 50% higher data rates possible in the return path than previously possible based on its low noise receiver and hardware based DOCSIS 3.0 channel bonding capabilities. For example, with a 5-42 MHz return path connected to the RX48, it will be possible for the first time for cable operators to support 100 Mbps dedicated for business services in only three bonded return path channels instead of four, leaving three return path channels available for residential data services, all supported using only a single RX48 port in the CMTS.
