AT&T Business Fiber combined with built-in LTE backup gives your Phoenix operation genuine redundancy using two entirely separate network technologies.
The primary fiber connection runs on underground dedicated infrastructure. The LTE backup runs on AT&T's cellular network across Maricopa County towers. A physical infrastructure event that takes down the fiber line does not affect the cellular network. A cellular network issue does not affect the buried fiber line. Your Phoenix business stays online regardless of which pathway encounters a problem.
For operations in the Deer Valley business district, along the Camelback commercial corridor, or in any of Phoenix's dense commercial zones, that infrastructure separation is exactly what real disaster recovery planning requires.
