Out-of-band access is essential for any network manager, to be able to access routers and other network devices in case primary communications is not available. Traditionally, phone lines (PSTN) were available for such purpose, but traditional wired connections are more difficult to obtain and much more costly. 4G out of band access removes that problem, by connecting a 4G router to your equipment, you'll have anytime access to your device through USB, serial or ethernet port. Blue Wireless provides Cradlepoint equipment and 4G SIMs in 16 countries, so you're never out of connectivity.
