For those homes that do not have a WiFi router in place, a Smartphone or WiFi Hotspot can serve as the access point for Array (in lieu of a router).
This means that the smartphone or Hotspot will need to stay with the Array lock for the lock to stay connected.
To connect the Array to a hot spot in a smartphone, you will need 2 devices, one with the hot spot and one with the Array app. You can not connect the Array to the Hotspot in a phone and also connect the Array to the same device.
