Communication modules

Communication modules are electronic systems that enable data transmission over a distance. These can be both data in the form of transmitted information, as well as control signals. Although the term is usually used in the context of remote transmission, all communication modules, including wired transmission links, can be defined.

Communication modules - wired and wireless data transmission

Electronic modules with communication properties have miniature dimensions, are characterized by high reliability and uncomplicated implementation. They are used in many everyday devices, as well as in industry, hobby and toy industries. They ensure the transmission of signals over a distance and enable both wired and wireless transmission.

Although some solutions, such as, for example, most robots, RC models (radio-controlled models of cars, airplanes, etc.) or drones, by definition, require wireless communication, in many cases constructors and designers of devices at the very beginning of the prototype development process must decide on a wired or a wireless method of communication. The effectiveness of a given method depends on many factors that are taken into account, including:

  • range,

  • bandwidth,

  • type of environment.

A long distance usually indicates a wireless solution, for example with the use of GPS or radio modules, and in turn, for example, the aquatic environment in a way forces the choice of wired links - exploration robots always communicate with a unit located on the water surface "on a cable". Transmissions over short distances, especially if the devices are located in one place (e.g. in the housing of a larger machine), are most often also made by wire due to the lower cost and simplicity of the solution.

Wireless data transmission and remote control of devices

The choice of a specific wireless data transmission solution depends on many factors, although, of course, not all possibilities are always checked when designing new devices, often adopting ready-made solutions. Electronic gadgets, computers or mobile home appliances usually communicate using WiFi and Bluetooth modules, although it is obvious that smartphones also have built-in GSM / LTE modules.

In turn, in measuring and control devices that often use low-power connections with low bandwidth and at the same time long range, apart from simple solutions in the ISM band, modules operating in the XBee, ZigBee or LoRa technology are installed. Geolocation takes place with the use of GPS modules, and remote control of devices is provided by infrared modules.

Transmission using wired communication modules

The vast majority of wired solutions use serial transmission. This means that each bit of the signal is sent one after the other (i.e. in serial order). On the receiver side, the bits are "assembled" into bytes, frames and data packets. Physically hardware transmission controllers, and at higher levels - software, are responsible for this. Currently, the most commonly used are USB and Ethernet modules that are compatible with many systems and devices. On the other hand, small amounts of data over short distances are supported by RS232 links, on larger ones - RS422 and RS485, and the automotive industry uses CAN modules resistant to interference and errors.

Electronics for everyone - Arduino

Anyone who wants to start their adventure with electronics in an easy and fun way should choose the Arduino. A microcomputer with additional modules, created by an Italian company, allows you to construct many gadgets in the comfort of your own apartment to make your life easier or to keep you entertained. Although the knowledge of the C language will be useful for programming Arduino, due to the large international community of system enthusiasts, there is a huge amount of ready-to-use programs available on the network, so even this skill is not necessary to construct a working roller shutter controller or automatic feed dispenser for the cat.
