Motorola Mobility Sets New Upstream Data Transmission Record Using Innovative EuroDOCSIS® Return Path Solution

Motorola Mobility, Inc. today announced the achievement of a new European record for return path data transmission at ANGA Cable in Cologne, Germany. The record-breaking demonstration indicates how cable operators can unleash new levels of upstream spectrum to deliver rich, residential broadband services while addressing new revenue generating opportunities such as business services, all within their existing EuroDOCSIS® 3.0 network.

The record of 288 Mbps for a 5-65MHz return path was set by transmitting across eleven return path channels of which four channels employed 256 QAM modulation, using the low-noise, high-dynamic range found within the Motorola RX48 return path receiver operating within a Motorola BSR 64000 Cable Modem Termination System (CMTS). Typical HFC networks today have two or three upstream channels delivering an aggregate of 40-70 Mbps.

“To date, operators have several options to improve upstream throughout performance, although most of these lead to more complex and costly approaches such as running additional fiber or segmenting nodes,” said Joe Cozzolino, senior vice president and general manager, Network Infrastructure, Motorola Mobility. “With what we have achieved with the Motorola RX48 module, cable operators can count on upstream data rates to increase between 33 and 100 percent per channel at a dramatically different price point versus alternatives. It is this level of innovation that provides operators another option to improve network performance, with little impact to their bottom line.”

Demonstrations of the test are available at the Motorola Mobility booth (10.2/H31) at ANGA Cable, May 3-5, 2011.

About Motorola RX48 Decoupled Upstream Module

Motorola RX48 provides between 33 and 100 percent higher data rates in the return path than previously possible based on its low-noise, high-dynamic range receiver and hardware based DOCSIS 3.0 channel bonding capabilities. For example, with a 5-65MHz return path connected to the RX48, it will be possible for the first time for cable operators to support 100 Mbps dedicated to business services in only three bonded return path channels instead of four, leaving three return path channels available for robust residential broadband services, all supported using only a single RX48 port in the CMTS.
