The Huawei B525s-23a is a LTE Cat6 router typically used in homes or small offices. One of its hardware limitations is that the LAN ports are only 10/100 Mbps (Fast Ethernet), even though the LTE modem is capable of download speeds up to 300 Mbps.

The feature solves this bottleneck by allowing the user to combine two physical LAN ports into a single logical connection. This allows devices with compatible network interfaces (like a NAS, high-end PC, or a Wi-Fi Mesh backhaul) to exceed the 100 Mbps physical limit by utilizing the full potential of the LTE connection, while simultaneously providing automatic failover.
