For demanding wireless connections, that is, those which need high uptime, high capacity, or high peak data rates, we often need to look at bonding or load balancing multiple 4G-5G connections together.
A Load Balancer is a type of router which maintains two or more WAN connections and attempts to distribute internet traffic fairly between them. Because each web connection must take a single route from sender to receiver, a Load Balancer provides more capacity (supports more users) but cannot increase maximum internet speeds.
When faster per-connection speed is required you may need a Bonder. This type of device aggregates two or more connections together to create a single ‘pipe’ for traffic to flow through. It works by using a Cloud platform as a proxy, acting as a single route between sender and receiver. Traffic is then tunnelled between the Cloud and Bonder over multiple internet connections.
Bonding can be a great way to escape heavy network congestion by splitting traffic between different providers or technologies. One consideration with a Bonder is that they typically require paid subscription to the cloud platform provider.
