4G LTE Mobile Phone Gate Access Controller UAE
The WH-120 PRO 4G GSM Gate Opener Controller is a professional mobile-phone access controller designed to operate compatible automatic gates, parking barriers, garage doors, rolling shutters, automatic bollards, access-control doors and other electrical systems through the mobile network.
The controller uses a Nano SIM card and verifies incoming calls using authorised caller ID. When an approved user calls the installed SIM number, the WH-120 PRO can activate its relay output and send an opening command to the connected gate or access-control system.
Because the system communicates through the mobile network instead of a short-range gate remote, users can operate the automation from locations far beyond normal radio-remote range, provided suitable mobile-network service is available.

Designed for 4G LTE Mobile Access
The WH-120 PRO 4G uses mobile-network communication rather than short-range gate-radio transmission.
This makes it useful for access systems where users need to operate a gate without being physically close enough for a conventional gate remote.
How the WH-120 PRO Works
A Nano SIM card is installed inside the controller and authorised telephone numbers are stored in memory.
When a registered user calls:
- The controller receives the incoming call.
- The caller ID is checked against the authorised-user list.
- If authorised, the output relay activates.
- The connected gate control board receives an opening command.
- The automation responds according to its own programmed logic.
Caller ID Access Control
The system uses the telephone number of the caller as an access credential.
Unknown telephone numbers are not intended to activate the relay when caller-ID authorisation is correctly configured.
No Traditional Gate Remote Required
Users can access the gate using their mobile phone without carrying a dedicated RF gate transmitter.
This can reduce the number of physical remote controls required for apartments, companies, warehouses and multi-user parking facilities.
No Local Radio-Distance Limitation
The WH-120 PRO does not rely on a short-range 433 MHz or 868 MHz signal transmitted directly from the user's phone.
Operation instead depends on mobile-network connectivity.
For professional wording, use:
“Remote operation from anywhere with suitable mobile-network connectivity.”
Avoid guaranteeing literally unlimited distance under every network condition.
No Wi-Fi Required
Call-based operation does not require the gate location to have Wi-Fi or fixed internet service.
The controller communicates through its installed SIM card and cellular network.
Call-Charge Function
The WH-120 PRO can be configured to identify an authorised call and activate the relay without requiring a normal voice conversation.
This is commonly promoted as a no-call-charge access method.
Actual billing behaviour can still depend on the SIM provider, telecom network, roaming status and service plan, so avoid guaranteeing zero charges under every telecom condition.
SMS User Management
Authorised telephone numbers can be added or removed through supported SMS programming commands.
This allows an administrator to change gate access without physically attending the controller each time.
User Capacity
Your current page says the WH-120 PRO supports 200 or 1200 authorised users depending on configuration.
This wording should only remain if you actually stock both memory-capacity versions.
If the product you sell at this URL is specifically one version, use the exact capacity:
“User Capacity: Up to 200 Authorised Phone Numbers”
or:
“User Capacity: Up to 1200 Authorised Phone Numbers”
Do not make customers guess which version they are purchasing.
Relay Output for Gate Control
The output relay is normally used as a control contact for the connected gate automation.
Typical control-board terminals include:
- OPEN
- START
- STEP-BY-STEP
- SBS
- PUSH BUTTON
The exact connection depends on the gate motor manufacturer and control-board model.
Dry-Contact Gate Connection
For automatic gates, the relay is normally connected using COM and NO contacts to a compatible voltage-free command input.
The GSM controller does not normally replace the gate motor's main control board.
Do Not Directly Power the Motor
The WH-120 PRO relay should normally be used to send a command to the automation controller.
Do not use it to directly switch a gate motor or other heavy load unless the complete electrical design is specifically suitable for the relay rating.
Sliding Gate Motor Compatibility
The WH-120 PRO can work with many automatic sliding gate motors where the controller provides a compatible external command input.
This can include gate motors from multiple automation brands because the GSM device acts as an external relay command.
Swing Gate Compatibility
The controller can operate compatible swing gate control panels through their START, SBS or OPEN command terminals.
Garage Door Compatibility
Garage door openers can be integrated where a wired wall-button or external command input is available.
Parking Barrier Compatibility
The WH-120 PRO is suitable for compatible parking barriers that provide an external OPEN or trigger input.
This can be useful for residential parking, employee entrances, visitor access and gated communities.
Rolling Shutter Compatibility
The relay can also interface with compatible rolling-shutter controllers.
The exact connection depends on whether the shutter controller uses a single step command or separate OPEN and CLOSE inputs.
Automatic Bollard Compatibility
Compatible automatic bollard controllers can be triggered through an external relay command for authorised vehicle access.
Access Control Applications
The controller can be used with suitable access-control doors and other systems where a compatible dry-contact input is available.
If electric locks or magnetic locks are used, a proper access-control power supply and relay arrangement should be provided.
External Wired Push Button
The WH-120 PRO supports an external wired-switch input.
This can be useful for:
- Guard-room push buttons
- Reception desk controls
- Local manual opening
- Security-room switches
SMS Relay Confirmation
The product family supports configurable SMS confirmation after relay activation.
This function may be useful where the administrator wants confirmation that an access command was processed.
50 Ω SMA Antenna
The WH-120 PRO uses a 50 Ω SMA antenna connection.
This allows the antenna to be positioned away from a metal control cabinet if necessary to improve reception.
Wide Power Supply Range
The controller supports approximately:
- 9–30V AC
- 9–36V DC
This makes integration possible with many access-control and gate-automation power supplies, provided voltage, current and polarity requirements are correctly observed.
Suitable for UAE Installations
The controller's listed operating temperature is approximately -10°C to +60°C.
For UAE installations, mount the controller inside a suitable protected electrical enclosure and avoid direct sun exposure, water ingress and excessive cabinet temperature.
Do Not Advertise It as Weatherproof
Your current page says the controller works reliably in dust and humidity, but no weatherproof IP rating is shown.
Do not describe the bare controller as waterproof or outdoor-rated unless you have an official IP rating for the exact enclosure.
Use:
“Install inside a suitable protected electrical enclosure for outdoor gate applications.”

WH-120 PRO 4G vs Wi-Fi Gate Opener
A Wi-Fi controller depends on the site's Wi-Fi network and internet connection.
The WH-120 PRO instead operates through its mobile SIM/network service.
This can be useful for gates and barriers where property Wi-Fi is unavailable or unreliable.
Nano SIM Requirements
Before installation, confirm:
- Nano SIM is active
- 4G LTE service is enabled
- Supported LTE bands match the network
- Caller ID presentation is enabled
- SMS service is available if SMS programming is required
- SIM PIN is disabled if required by the controller
- The account remains active
Professional Installation
A typical WH-120 PRO installation includes:
- Power-supply connection
- Nano SIM installation
- SMA antenna positioning
- Relay wiring to gate control input
- Administrator-number setup
- Authorised-user programming
- Relay-time setting
- Network-signal test
- Call-access testing
Gate Opens from Push Button but Not GSM
If the gate works normally from its wired push button but not from the WH-120 PRO, check:
- SIM activation
- 4G network signal
- Caller ID
- Authorised telephone number
- Relay programming
- Relay wiring
- Antenna connection
Relay Clicks but Gate Does Not Open
If the WH-120 PRO relay activates but the gate does not move, verify that COM and NO are connected to the correct gate-control input and common terminal.
Also confirm that the gate input requires a voltage-free contact rather than external voltage.
