Most modern buildings have cellular coverage gaps.

These gaps are a drag on people and your bottom line.

There are several factors that can impact signal strength by the time it reaches you. Consider the amount of time people in your building(s) spend locating a reliable signal, running outside to get service, or sitting in their car to make a call. Not being connected can raise stress levels, reduce productivity, and slow transactions. While Wi-Fi can help, it’s not a substitute. You need both.
