Gates of two warehouses opened from a head office 200 and 330 km away
Control of the entry gates of two warehouses from the company’s head office, and recording of drivers’ arrival times: a remote control, a GSM transmitter at the warehouse and a gate controller that responds to a text or a CLIP call.

01 / Investment context
What problem had to be solved?
A logistics company with a fleet of several dozen vehicles has two warehouses 200 and 330 km from its head office. Drivers from that fleet arrive at both, and head office wanted to control the entry gates of both warehouses itself and to know what time each driver arrived.
A gate remote in every driver’s cab opens the gate without head office knowing and leaves no record of the arrival. Someone on site to open the gate is an extra cost at every warehouse. What was needed was a way for the driver to report arrival while head office decides on entry — even though hundreds of kilometres lie between them.
The investor’s goal: Control of entry to both warehouses from one place, regardless of distance, with each driver’s arrival time on record.
What was designed?
On arriving at the warehouse, the driver presses a key on the remote control (PUK-303). At the warehouse a GSM transmitter with a radio receiver picks up this signal and sends a text to the mobile phone of the supervisors at head office. Head office knows which gate to open and sends a text or a free CLIP call to the gate’s GSM controller — the controller triggers the drive’s control input and the gate opens.
Once inside, the driver presses the remote again: “I’m in, you can close.” The time of the arrival report stays in the text on the head-office phone. The installation used an ATG-SG2/RF transmitter and a GSU-B02 controller; in these roles GORKE today uses a GSM transmitter with a radio receiver (ATG-SG4RF), the successor to the ATG-SG2/RF, and an LTE GSM controller (GSU-K02/L).
02 / Operating principle
From signal to action.
The driver reports arrival with the remote; head office receives a text and opens the warehouse gate itself by phone.

Gate Warehouse entranceThe drive opens the gate and the driver can drive in.
The decision on entry stays with head office. The gate is opened by head office, not by a remote in the cab — 330 km away just as in its own yard, because mobile coverage is what counts.

03 / Installation components
The installation’s devices and their equivalents today
The models used in the project, with their equivalents in the current range.
ATG-SG4RF
GSM transmitter with a radio receiver at the warehouse gate: picks up the driver’s remote and sends a text to head office. Successor to the ATG-SG2/RF model used in the installation.
Quantity: 1 per warehouse
GSU-K02/L
GSM gate controller, LTE: on a text or a free CLIP call from the head-office phone it triggers the drive’s control input. Today’s equivalent of the GSU-B02 model used in the installation.
Quantity: 1 per gate
AMD-G30
5 dBi GSM antenna on a magnetic base, where coverage at the warehouse gate is too weak for the antenna supplied with the device.
Quantity: optional
Catalogue figures describe a device under stated conditions, usually in open terrain, and are not a guaranteed range in every installation. Device quantities in the examples are indicative.
04 / Value for the investor
What does this solution give you?
Distance does not matter
What counts is mobile coverage, not radio range: head office controls a gate 330 km away just as it would one in its own yard, and each further branch is just another pair of devices.
Record of arrivals
The time of every arrival report stays in the texts at head office, so nobody has to phone the drivers to find out when they arrived.
Control of entry
The gate is opened by head office, not by a remote in the cab: the driver reports arrival, but the decision on entry stays with head office.
05 / Before installation
What needs to be settled for a similar investment?
Before devices are chosen, what matters is the site’s conditions and how the system ties into the final installation.
Requirements to verify
- Mobile coverage at the gate of each warehouse — it decides whether an external antenna is needed.
- Who answers the head-office phone that receives the texts, at what hours, and what happens to an arrival outside those hours.
- The gate drive’s control input: the GSM controller switches the drive’s control circuit and does not power the motor. Power for the GSM devices is also needed at the gate.
- The phone numbers from which head office opens the gates, and how they are entered in the controller’s configuration at commissioning.
