> On the other hand, have you looked at getting a femto cell for your warehouse (or using a service like Google Voice to get wifi calling)?
I'm the only employee using a T-Mobile compatible phone so it wouldn't be worth doing. We've put WLAN access points throughout the warehouse (one of my first projects when I went full time there) so it's saturated with Wi-Fi. I can't use Google Voice or Hangouts for receiving calls, since I mainly use a Windows phone, but I do have that set up on my Nexus and it works well there.
Basically, 99% of what I use my cellphone for at work is covered by Wi-Fi, and if anyone needs to reach me they can just call the company.
