LTE Failover vs. LTE Out-of-Band

This post was originally published on ZPE Systems

What is LTE failover?

LTE failover uses a cellular data connection – such as 4G or 5G – to provide backup internet access in the event that the primary connection goes down. Since LTE uses cellular infrastructure, it’s often unaffected by events that may cause a wired ISP network to go down, such as natural disasters, construction accidents, and power outages. When the cellular failover router detects that the primary internet connection is offline, it automatically takes over to ensure continuous network availability. The goal of LTE failover is to provide reliable, 24/7 internet access for production network resources and users. An automated failover solution reduces the impact of ISP outages by allowing businesses to continue operating as usual with a seamless experience for end users.

What is LTE out-of-band?

LTE out-of-band (OOB) management, on the other hand, uses a cellular data connection to provide continuous management access to remote network infrastructure. Cellular OOB solutions typically use serial consoles (i.e., console servers, serial switches, or serial routers) to directly connect to production network infrastructure such as servers, PDUs, and storage devices. Administrators remotely access these serial consoles using a dedicated cellular interface, and
