Teledyne Paradise Datacom announced the addition of a major new feature to its QMultiFlex-400™ Hub for point-to-multipoint satellite IP systems. 
 
Today, Operators desiring frequency re-use between outbound and inbound carriers must deploy a separate unit after the modem in a point-to-multipoint system. By utilizing the QMultiFlex-400 with its unique Embedded Hub Canceller, operators can now enjoy several major advantages, including up to 50 percent bandwidth cost savings, a smaller footprint—less required rack space, reduced power consumption, simpler and easier to deploy and operate. Additional bandwidth saving features include DVB-S2X, ACM, TCP Acceleration, and header and payload compression.  
 
“By enabling a ‘two units in one’ solution, the embedded hub canceller builds even further on the unique engineering design advantages offered by the QMultiFlex in the first place,” said Paul McConnell, business development director at Teledyne Paradise Datacom UK. “QMultiFlex already enabled Operators to replace an entire rack of hub equipment with a single box, at a fraction of the price. With this new feature, QMultiFlex now supports the broadest and most powerful suite of bandwidth-saving technologies on the market, and all in a single box.”  
 
By deploying the Hub Canceller, operators can overlay the inbound carriers underneath the outbound carrier either wholly or partially, substantially reducing operational expenditures. A single modem with an embedded canceller is used at the hub, and no additional equipment is required at the remote locations. The technology uses adaptive self-interference cancellation to remove the outbound signal, which is present within the inbound signals using the same frequency band. The resulting canceller output is the desired signals from the remote terminals. 
 
The QMultiFlex-400 supports up to 16 integrated demodulators. Other notable features include XStream IP™ advanced IP optimization, the Q-NET™ Navigator network control application, and data rates to 345Mbps outbound and inbound. QMultiFlex-400 is ideally suited for IP trunking/backhaul and cellular backhaul, broadcast, Comms-on-the-move, maritime, oil and gas and corporate and governmental networking applications.
