GSM Automation

Diagram explaining how GSM automation works

How does GSM Automation work?

  1. User calls the number of a SIM card contained within the GSM controller
  2. If the GSM Controller recognises the number of the caller, it rejects the call and instructs the gate or door to open or close. If not, no action is taken.
  3. The GSM Controller sends an optional SMS message to confirm the action has been carried out.
