A RECORD of 356Mbps for a 5MHz to 85MHz return path has been claimed by Motorola Mobility and Cox Communications.

Taking place in the Las Vegas area, the record was said by the firms to have been achieved by transmitting across twelve return path channels. According to the two companies, typical hybrid fibre coaxial networks today have two or three upstream channels delivering up to 70Mbps.

The 356Mbps data rate was achieved using a Motorola Docsis 3.0 RX48 return path receiver module, as part of the Motorola BSR64000 CMTS Edge Router.

"We are very pleased to show the results of Motorola Mobility's investment in Docsis 3.0 innovation," said Joe Cozzolino, SVP and general manager of network infrastructure for Motorola Mobility.

In addition to establishing the record at 5MHz to 85MHz, a maximum transmission rate of 141Mbps was also achieved over a 5MHz to 42MHz return path using six return path channels.

According to Motorola a 5MHz to 42MHz return path using Motorola and Cox hybrid fibre coaxial network technology will make it possible for cable operators to support 100Mbps in three bonded return path channels instead of four, leaving three return path channels available for other data services.

All tests were conducted across Cox's Las Vegas hybrid fibre coaxial network employing multiple Docsis 3.0 and Docsis 2.0 modems. µ
