Radio transmitter

Would you like to automate an existing electrical installation at low cost without having to open walls and lay many lines or cables? Do you want to retrofit or expand your smart home? Then both radio transmitters and radio receivers belong on your shopping list. Find out more here about the possibilities that radio transmitters and radio receivers offer you. Radio technology has become an integral part of our everyday life. Think of radio signals, television and mobile phones, the Internet and many other things.

WLAN or Wi-Fi?

WLAN is a wireless radio network limited to a local area. Wi-Fi is more of a brand name of a consortium of companies (Wi-Fi Alliance). For example, devices labeled 'Wireless Fidelity' receive WiFi.


In the field of radio transmitters, there are numerous device types and standards, such as Wi-Fi, Bluetooth, NFC and cellular.

What are radio transmitters?

A radio transmitter is an electronic device that generates radio waves. In the field of electrical engineering, the device mainly transmits control signals, switching signals, error messages and status messages. In telecommunications, radio transmitters are used to transmit or send data using an antenna. The transmitter converts the information into a high-frequency alternating current, which is radiated from an antenna as radio waves.

 


Already knew?

The Solt transmitter of the Hungarian 'Kossuth Rádió' is the most powerful radio transmitter in Europe. The program can be received in the USA and South Asia.


 

Depending on the type of device, the radio waves are emitted in a specific band of the electromagnetic spectrum. The division into bands serves to fulfill a wide variety of communication tasks. This includes the transmission of voice, images or very general data. The transmitter uses the current of its power source to provide alternating current according to its bandwidth in the required wavelength. This is the frequency at which the alternating current changes direction per second. The electromagnetic waves or radio waves are radiated outwards as a weak signal via a carrier medium (e.g. the air) via the antenna. A corresponding receiver reverses this process and amplifies the incoming signal in order to be able to process the actual message or data. A transmitter can be a separate device or an electronic circuit in another device.

How is a radio transmitter structured?

A radio transmitter requires an energy source that supplies the device with power and the energy for transmission. An electronic oscillator creates the radio waves and a modulator inserts the actual data into the radio wave. It does this through small variations in the properties of the carrier wave. A high-frequency amplifier increases the power of the signal. This increases the range. And finally, an antenna tuner matches the impedance of the transmitter to that of the antenna. This makes the energy transfer to the antenna efficient and prevents what is known as a 'standing wave' (reflection of the energy from the antenna back to the transmitter).

How important are radio transmitters in building automation or the electrical installation?

You use radio transmitters when there is no power line or bus line at a certain point in your installation. There you position a radio receiver, which receives the signals from the transmitter and takes over the desired tasks. These can be switching actions and control functions or the display of information. Radio transmitters are therefore an alternative when flexible installations are desired. Radio transmitters are also suitable if you want to retrofit existing analogue installations and device controls. Radio transmitters are a simple and inexpensive solution for home automation and are used to increase living comfort.

You can get a large selection of radio transmitters in the eibabo® technology store

  • for flush mounting (radio transmitter modules, universal transmitter)
  • for operation (radio buttons, KNX remote controls, hand-held transmitters)
  • for control (wireless weather stations, multiple wall switches, room temperature controllers, wireless window contacts and other sensors)

 

from all well-known manufacturers. These include top brands such as SOMFY, Rademacher, Warema Sonnen, Eltako, Schalk, Sommer and Jung. You will also receive devices and accessories from Hager, Eberle Controls, Berner Torantriebe and EVN Lichttechnik. We also offer elegant wall transmitters that are suitable for flexible installation on wallpaper, glass, mirrors, tiles or wood. Or you can select immediately functional wireless motion detectors, wireless switches or wireless sets from our range.

What is the range of radio transmitters in electrical engineering?

The range of radio transmitters can vary greatly. This depends both on the radio technology used and on the environmental conditions. Ranges between 20 meters and one kilometer are usually specified. The specifications in the product information about the maximum range are usually values under optimal conditions. These exist when there is a direct line of sight between the transmitter and receiver without obstacles and the area is not affected by interference signals from the same or a neighboring frequency band. Please keep in mind that these conditions rarely apply and the range will therefore be lower in practice.

 


TIP:

When installing radio transmitters, allow for a range reserve of 25%.


 

The reserve is not only used to compensate for a lower range due to current obstacles. If further obstacles are added later (e.g. additional walls or growing trees), the devices can still be used.

What is an I/O radio module?

I/O radio modules are so-called transceivers, a combination of transmitter and receiver. These therefore have signal inputs and signal outputs. This makes it possible to control or monitor systems with just one radio link. In addition to digital interfaces, some models also offer analog inputs for transmitting sensor values and limit values.

What do I have to consider when buying radio transmitters?

If you want to use radio transmitters, you need additional receivers that pick up the signals, process them and react accordingly. This can be, for example, switching actuators, universal displays or radio-controlled sockets. To ensure that communication between transmitter and receiver works, all components are parameterized using the standardized 'Engineering Tool Software (ETS)'. In this way, each device knows under which conditions it should send or receive commands and how it has to react to changes. The ETS software is available from www.knx.org and is a tool that you need to commission and link KNX devices. Don't worry: programming skills are not required. The ETS is also suitable for laypersons who are interested in the logic of the KNX. Please make sure that your radio transmitter can take over the transmission tasks you want and carry them out correctly. We therefore recommend that you carefully check the parameters and functions for the ETS provided by the manufacturer before purchasing.
