OVERVIEW
The QFlex-400™ software-defined satellite modem, a variant of our flagship Q-Flex™, is our highest data rate modem. Compared to the standard Q-Flex™, it supports much higher data rates, an extended frequency range, better RF performance, improved carrier cancellation, more headroom for future upgrades and lower power consumption.
It is ideal as a versatile point-to-point network modem or a remote modem in a point-to- multipoint network. It is fully compatible with our Q-NET™ satellite network solution and is a drop-in replacement for the Q-Flex™/Q-Lite™.
