@MartinLangmaid has written a few articles about live streaming

From our experience, if you can get your require bandwidth from one SIM card, use SpeedFusion hot failover to give you the reliability and zero packet loss. The WAN soothing feature is also great for uploading video streams.
Bonding and failover between 3G, 4G, ADSL, Fibre and Satellite is possible but its recommended to only bond connections of similar characteristics (speed, latency etc)
However it is fine to use SpeedFusion hot fail over between different types of connections
Thank You
