The GSM module allows you to remotely control any automation by receiving a signal from a phone operating in the GSM range and turning the connected equipment on/off. It is used to open swing and sliding gates, barriers in parking lots, parking lots, in country and garage cooperatives, private houses, remote control engineering systems watering, lighting, heating, rebooting servers and routers.

This is how the owner opens the gate when entering the territory

The GSM module is most widely used as a reliable and low-cost controller for managing group access to a facility, compatible with the popular Doorhan and Came automatic gates and barriers.

How the module works

Essentially, a GSM module is a radio receiver with an installed sim card any operator cellular communications and a controller for processing incoming and outgoing information. The module database is entered phone numbers all users who have the right to access the closed area. Modern models support recording and storage of up to 2000 numbers; more expensive modifications are capable of processing up to 10,000 numbers.

The principle of operation of the device is shown in the figure.

Schematic diagram of the device operation

When making a call, the controller performs a verification incoming number with the recorded data, and if it is present in the memory, a command is given to open and activate the barrier and sliding gate drive. If the number is not in the list, the device simply drops the call without performing any further actions. In the same way, the controller opens swing gates equipped with an electric lock and a Doorhan or Came drive.

There is no connection with the calling subscriber, or it is interrupted after a few seconds, due to which the cost of paying for cellular services is zero. If the data does not match, then passage through the fencing device is not provided. In some models, it is possible to disable identification, and admission is carried out at any incoming call to the controller. The GSM module control unit is configured using SMS commands, a web interface, a program on a computer connected via a USB port, and an Android application for smartphones.

Let's give an example of a GSM module from the Tor-House LLC company. There are two models that differ in the number of user numbers and set of functions. Photo of the modules in the figure below.

Technical characteristics of the modules are given in the table.

Pros and cons of gsm modules

there is no need to purchase individual remote controls, key fobs or cards, and not all barrier control systems are “rubber” and are designed for a limited number of them;
You can open a barrier or gate from any place included in the coverage network mobile operator, thanks to which ensuring a friend’s access to the territory while being out of reach is not a problem, + simplifying the work of the security service;
control - with the help software or SMS commands, it is possible to add and remove numbers from the database, configure parameters such as admission by days of the week, time of day, entry ban for non-payment of mandatory fees, keeping a log of entries, etc.;
Possibility of installation on automatic barriers and gates of any manufacturer;
savings - the price of one GSM controller is approximately equal to the cost of three Came remote controls, and with a large number of users, such travel automation is significantly more profitable.

And a small fly in the ointment - a gate or barrier will not be able to be opened if the phone battery is low or zero balance, be they three times Doorhan or Came, but the same thing can happen if you, for example, forgot or lost the remote control.

Places of application

The modules are used to control any type of electrically driven equipment:

automatic gates, barriers;
boilers;
office doors (if equipped with an electric lock);
alarms;
cars;
and other devices.

We are already familiar with devices such as GSM/MMS cameras (), GSM alarms (), which send messages when a motion sensor is activated. These were the first devices using GSM modules and their use began to expand.

GSM modules are being actively implemented; they have shown the greatest effectiveness for control at the entrances to cottage villages, large residential complexes, and commercial facilities with a large number of personnel or clients.

Let’s say there are 5 houses in the Berezka residential complex, multiply 500 apartments by 1,500 rubles. ( average price key). The HOA will have to collect 750,000 rubles from residents. only for the purchase of keys.

It turns out to be a big economic benefit compared to buying keys!

It will be easier to persuade homeowners to buy an automatic barrier when the amount of investment in equipment and installation is 2000-3000 rubles per apartment.

If we compare it with RFID tags, which can also be used as a gate opener, then RFID identification is somewhat different; the equipment set is more expensive, but the range of applications is wider.

In the next article we will look at a module from the SmartAirkey company - keyless access to entrances and parking lots of apartment buildings.

Articles and Lifehacks

To the question what is a gsm module in a tablet, you can answer - this is a global digital standard designed for mobile cellular communications. Today a gsm module is additional function, giving users a unique opportunity to send SMS (short alphanumeric messages) and make calls, i.e. use the tablet like cellular telephone. After all, for many it is a problem, for example, and it has broken down - in this case, a tablet with a GSM module will allow you to stay in touch.

Capabilities of a tablet equipped with a GSM module

The main characteristics of the tablet: power, autonomy and portability. The power of a tablet with a gsm module is enough to work with by email And office applications, and for relaxation during travel and entertainment (watching videos and photos, as well as playing games). Tablet - miniature laptop, connected to worldwide network, making it easy and simple to share with friends and co-workers necessary information. It allows you to perform office work without connecting to a power source, working in GSM networks.

An important feature of such tablets is the presence of a built-in module that allows you to receive calls. Such a device (simple and safe to operate) has high performance, and performs all tasks assigned to it quickly and accurately. The advantages of the tablet include its compact dimensions and light weight. It's also worth having an idea while working with it. We figured out what a gsm module is in a tablet and what its purpose is. Let's consider the stages of its appearance.

The history of the gsm module built into the tablet

Analogue systems mobile communications received rapid development in European countries (Scandinavia, Great Britain and Germany) in the early eighties. Each state developed an individual system, which was incompatible with others in terms of functions and equipment. However, this situation limited the scope of activity of mobile devices (working within one country), which did not allow expanding sales markets. In Europe, a decision was made to create a common terrestrial cellular communication system. By the mid-90s, about 200 GSM networks existed in 110 countries around the world, and today they operate on almost all continents.

This device provides a large number of services related to the transfer of information. Thanks to the gsm module, the transmitted speech is digitized and transmitted as a digital stream over the gsm network. Users of these networks receive and transmit data to users of traditional telephone networks. Since gsm is a digital network, a modem is not required for the user to interact with the network.

Before understanding how GSM works, it is important to understand what GSM is.

GSM is an international digital standard of planetary significance, the name of which comes from the phrase “Groupe Spécial Mobile”.

This standard is intended for mobile cellular communications with channel division. Channels are divided according to the TDMA principle. The standard was developed by the Telecommunication Standardization Institute back in the late eighties of the last century.

The very first similar system was created back in 1946 in the United States of America. The global adoption of mobile communications began only in 1979.

Standardization

Before the launch of GSM, at the very beginning of the eighties of the last century, 24 analogue networks operated on European territory. They were not compatible with each other, so the issue of creating a single standard became relevant. The need to solve this problem was the reason for the creation of the GSM (Group Special Mobile). This group included representatives from 24 European countries. The Mannesmann system was chosen as digital standard, and this system was introduced in 1991 in Germany.

The abbreviation GSM today hides a slightly different phrase - Global System for Mobile. The GSM standard itself or its versions operate successfully in 80 countries around the world.

How GSM works

In order to implement this type communications in a certain territory, the following actions apply:

Installation of stationary transmitting and receiving stations. Each station operates in relatively small areas of several kilometers.
The stations are arranged in such a way as to overlap each other. This allows the subscriber’s signal to move from one zone to another without disrupting the connection.

To implement this type of communication, in practice, neighboring stations are tuned to different frequencies. There are usually about three such frequencies. Using three different frequencies, stations arranged in a triangle overlapped service areas.

There is also a fourth station that can use one of the frequencies again. This is possible since it borders two zones. Thus, the station's coverage area will resemble a hexagon, having the appearance of a honeycomb.

GSM modules

Everyone has heard, but not everyone knows what a GSM module is. Meanwhile, this is a very useful device that uses GSM principles. More specifically, a gsm module is a device that helps monitor the location of your car. This device works in conjunction with an alarm or mobile phone. You can also block the engine if necessary.

Using this module, a mobile subscriber is identified. You learned about this when you read about what the GSM network is.

Advantages and disadvantages of the GSM standard

Advantages of the GSM standard:

Smaller dimensions and weight of devices compared to analog standards. At the same time, the operating time without recharging is noticeably longer.
The quality of communication is at a very high level.
Low level of interference at specified frequencies.
Protection against eavesdropping. Also, due to encryption algorithms, communications are protected from illegal use.
Extensive distribution areas.
Possibility of using roaming. Roaming is the ability to move from one network to another without losing your number

Disadvantages of the GSM standard:

In view of digital processing speech, speech may be somewhat distorted.
The distance covered by the network is not too large. It is only 120 kilometers.

Thus, for now, gsm remains a developing technology, but, nevertheless, its importance in the world cannot be overestimated. After all, we use it every day.

One of the popular security systems installed on cars is the Starline GSM module, equipped with a special mobile communication module. It can be used to communicate with security complex from any phone operating in cellular communication systems via GSM standard. The popularity of this solution can be explained quite simply: such systems are capable of maintaining two-way communication between the owner and the car without interference and over a long distance, which in some cases cannot be provided by a standard alarm system.

Main advantages of GSM modules

At their core, these security systems differ from their conventional counterparts in the ability to establish communications similar to conventional cellular telephone communications, and this is now provided almost everywhere, which means that the distance between the car and its owner does not matter. Thus, to establish communication where the alarm key fob does not work, you can use regular phone or smartphone.

This opportunity is carried out using a special module, which is functionally a cell phone with greatly reduced functions, which, however, has its own number with a registered SIM card, which is installed directly on the module, can receive and send calls, notifications and SMS, and exercise control for the condition various systems car.

Functions and capabilities of GSM systems

A car alarm with a GSM module, depending on the model, allows you to perform the following actions:

Enabling and disabling the security mode using a mobile application or a simple text message;
Starting and stopping the engine, performing autostart;
Checking the current state of the system and individual parameters of the vehicle as a whole;
Determining the location of the vehicle in real time;
Wiretapping the car interior using a microphone.

These functions are basic and in most cases, in addition to them, there are other service capabilities. Some operations are performed using a key fob, and some specific ones are performed only using a phone. By the way, for some models the ability to control the security alarm functions from a special Internet page is also added.

Adding a GSM module greatly increases security and resistance to theft - because in this case, it will be impossible to disable such an alarm by breaking the code and intercepting the radio signal. In addition, in modern cars, to ensure the ability to monitor and control many vehicle functions, the security alarm system is so integrated into the on-board electrical network car and the engine management system, which actually becomes part of it.

In many cases, the connection is made via standard wiring, therefore, such alarms are, in fact, among the most secure.

What types of Starline alarms with GSM module are there?

In order to understand what capabilities security systems with a GSM module have, you can consider specific models.

One of the most affordable models is Starline 2CAN 35. This model is equipped with immobilizer and anti-grabber functions standard for security systems to prevent unauthorized access to the car and its theft without the owner. The GSM module provides communication with the owner’s phone and allows you to learn about the most important changes in the vehicle’s condition by connecting to the CAN bus. In security GSM alarms budget class, the module itself, responsible for cellular communications, is designed as a separate printed circuit board and often does not have its own housing - it is inserted into an already existing building main block.

As for the more expensive models from Starline, in this segment you can consider the D94 model with GSM modules and GPS. Almost all the functions inherent in modern alarm systems with cellular communication capabilities are also present here. High resistance to burglary and theft is ensured by a multi-factor verification and user identification system. An individual code that changes with each arming, a built-in immobilizer and multiple locks ensure high reliability of this type alarms.

This alarm can be controlled from a regular key fob (in this case, the manufacturer promises a range of up to two kilometers), while the radio channel is well protected from interference thanks to the narrow-band transmitter.

Using the key fob, you can remotely start and stop the engine, as well as configure its automatic warming up based on time or coolant temperature. The key fob has a unique shape, thanks to which it can be distinguished from the key fob of, say, a Panther alarm system, the model of which can also be recognized by its shape.

Starline D94 GPS is equipped with special 3D sensors that respond to impact and tilt, which can be adjusted remotely. This function can be useful when evacuating a car from a parking lot.

A special feature of the Starline alarm system is its full integration with the on-board 2CAN interface, which greatly simplifies installation, configuration and further operation. By contacting electronic system motor and bus control security system gets access to many changeable settings car: control of various electric drives, notification of changes various parameters and the possibility of promptly changing them.
And the most main function this system– GPS positioning capability, thanks to which it becomes possible to very accurately track the location of the car directly from your smartphone. In principle, cheaper and simple systems they also know how to do this, but their geolocation is carried out using cell towers, and this is not always an accurate determination of the location, in addition, there must be quite a lot of points for anchoring (at least three).

One of the competitors of this system is the Sky GPS-GSM alarm system with similar functionality, but in terms of ergonomics and ease of use it is far from being comparable to Starline products. However, the price is more than attractive.

Installation Features

Installing the GSM module itself is quite simple. The main nuances depend on specific model alarm and the car itself. There is also a big difference between whether only the module itself will be installed or the entire security system in its entirety. If in the first case you can get by independent work, then in the second case it would be wiser to seek help from professional installers.

The basic algorithm for installing a GSM module is as follows:

Part of the instrument panel or instrument panel is removed to provide access to the alarm unit.
The removed alarm unit is disassembled and a board with a module is installed in the designated area. Some models have a special groove into which it is inserted. You must first install a SIM card on the module.
The main alarm unit is assembled, all wires and connectors are connected to it, and after that the entire unit is returned to its place, all subsequent work is carried out in the reverse order.

The entire system is configured, the SIM card number is registered and then the system can be used.
