Q-FLEX - DUAL IF/L-BAND SATELLITE MODEM

Dual IF/L-Band Satellite Modem

OVERVIEW

The Q-Flex™ modem embodies a new concept in satellite modem technology - a flexible soft- ware-defined modem that does what you want, now and in the future.

The Q-Flex™ modem’s flexible hardware platform provides IF and L-band operation in one unit. While its powerful processor makes it ideal for handling IP traffic, the Q-Flex™ modem can be fitted with virtually any type of terrestrial interface and will operate at data rates up to 160Mbps.

Flexible pricing is achieved by enabling only the features you need at any time. Future- proofing is assured by convenient software up- grades via Ethernet or a memory stick.

ADVANCED BANDWIDTH-EFFICIENT FEATURES

The Q-Flex™ modem supports the most power- ful bandwidth-saving technology available.

Paired Carrier™ overlays transmit and receive carriers reducing satellite bandwidth by 50% (using ViaSat’s patented PCMA technology).

Both DVB-S2, renowned for its robustness and bandwidth efficiency, and its successor, DVB- S2X are supported.

FastLink™ low-latency LDPC is optimised for latency-sensitive applications while giving coding gain that is close to the theoretical limits.

Bandwidth-saving IP features include acceleration and header and payload compression.
