Cut bandwidth costs and increase the capacity of your satellite
networks with the PCMA-70 Series of Satellite Bandwidth
Extenders from Paradise Datacom. This unit uses ViaSat’s
patented Paired Carrier Multiple Access (PCMA) technology to
reduce satellite bandwidth needs by up to 50 percent.
By simply adding the device to your satellite network, you can
expand the capacity of transponders, free up bandwidth for
more applications, and lower your network’s operating costs.
For example, while satellite space segment costs can vary
greatly depending on location and usage, a network operator
paying $5,000 per MHz per month for 20MHz can save up to
$600,000 per year on bandwidth by using the PCMA-70.
The PCMA-70 boosts the capacity of your satellite transponder
space by combining the uplink and downlink transmissions into
the same bandwidth. While most satellite transmissions require
separate frequencies to transmit and receive, this device
enables two different signals to overlap in frequency, which
increases the bandwidth available to the system.
The appliance uses an adaptive self-interference cancellation
technique to subtract your transmitted signal to recover the
desired signal. The canceller works with all modulation and
FEC techniques on “bent pipe”, non-cross-strapped satellite
networks to enhance the benefits of any advanced modulation
techniques or turbo coding you may already use.
With a 1RU form factor, the PCMA-70 fits into a standard rack
and interfaces with any digital satellite modem. The device
cancels signals with bandwidths of 1 to 36 MHz.
