What is a Wireless Cell Phone Network Intercom

A cell phone network intercom is an outdoor device that communicates wirelessly over the cell phone network with any landline or mobile phone worldwide. Often called GSM intercoms, they initially utilized the Global System for Mobile Communications standard. While GSM is used globally, in the United States, only AT&T, T-Mobile, and a few other providers use it. Sprint and Verizon use CDMA (Code Division Multiple Access) technology. The intercoms are now adapting to newer technologies such as LTE.

These intercoms have a module similar to a cell phone, modified for the needs of a call box intercom. The hardware is enclosed in a weather and vandal-resistant stainless steel box, with the speaker and microphone attached to the box. A Subscriber Identity Module (SIM) card is inserted into the cell module, identifying the subscriber to the network for billing and calling purposes.

Cell phone intercoms offer several advantages over traditional wireless intercoms. They have no range limitations; as long as there is cell phone service at the intercom's location, it can communicate globally.

When a visitor presses the intercom button, it dials the first programmed number. If there is no answer, it moves to the next number. Up to four phone numbers can be programmed, ensuring someone is reachable.

Upon answering, the property owner can have a normal phone conversation with the visitor. By pressing a key on their phone, they can open the gate if an automatic gate opener is installed.

Visitors can also use their phones as remote gate openers. If their phone number is programmed into the intercom, the gate opens when they call the intercom. Since the intercom doesn't answer the call, no minutes are used on the intercom's cell phone plan.

Property owners can use an App on their smartphones to control functions of the intercom such as these:

• Momentary, latch and unlatch control
• View an activity log (see who opened your gates and when)
• Remotely program your keypad PIN codes (for units with a keypad)
• Program automatic 7-day open/close times
• Program calling line ID numbers used for auto opening upon calling
• Verify if gates are open or closed (requires an optional switch)
• Program time restricted or temporary codes for visitors
• Program do not disturb times
