Q-NET Satellite Network Solution

Secure, Resilient, Software Defined

Q-NET is a scalable satellite communications system that supports highly-efficient bandwidth technology and sophisticated carrier and traffic management. It supports all types of network including star, full/partial mesh, point-to-point and hybrids. No expensive hub; no double hops; fully-functional network control application included as standard.



Secure and Resilient.  Satellite networks are under ever increasing cyber-attack and are also subject to accidental or deliberate interference that degrades services. Q-NET has a strong focus on security and on advanced signalling processing techniques that detect and mitigate all forms of interference.  


One system, boundless connectivity.  Uses a single building block for all types of networks, simplifying network expansion, operator training and logistics. Same equipment is used at hub and remote, regardless of whether network is point-to-point, point-to-multipoint, star, mesh, etc. Which means that in the future the equipment can be redeployed for any new network requirements that come along, rather than having to start over.


Simple IP. Single-box satellite modem solution for advanced IP, including traffic shaping, TCP acceleration, compression, VLANs and ACM.


Bandwidth efficiency. Supports the highly efficient DVB-S2X standard; low roll-offs on outbound and inbounds; carrier overlap technology.


Software Defined. Q-NET's support for Software Defined Network (SDN) protocols allow our satellite modems to be controlled in the same way as a network switch or router. SDN protocols virtualise the network, abstracting away all proprietary vendor hardware and command protocols, thereby allowing all terrestrial and satellite network equipment to be managed seamlessly from a single centralized control system. This makes it much easier for operators to provision new services regardless of the physical infrastructure and how that infrastructure changes over time.


Low cost. No expensive hub installation. Scales from very small to very large networks with minimal box count and no fixed hub costs.
