RF module supports low power consumption and can be operated in many remote regions.

An RF module is a small electronic device designed to send and/or receive radio signals between two devices. In embedded systems, it is often desirable to communicate without wire with another device.

RF module is widely used in electronic design because of the difficulty of RF circuit design. Good electronic radio design is complex due to the need to achieve specific frequency operation. Εξάλλου, reliable RF communication circuits require careful monitoring of the manufacturing process to make sure that RF performance is not adversely affected. Τελικά, radio circuits are often limited by radiation exposure and require certification and conformance testing by standardization organizations such as ETSI or the FCC. Ετσι, design engineers typically design a circuit for an application that needs radio communication and then “put in” a prefabricated radio module.

RF modules are most commonly used in consumer applications for medium and low-volume products such as wireless home automation systems, wireless alarm, συστήματα παρακολούθησης, ανοιχτήρια γκαραζόπορτας, industrial remote controls, smart sensor applications.

Several carrier frequencies are commonly used in scientific and industrial ISM bands such as 433.92 MHz, 915 MHz, και 2400 MHz. Short-range devices can also use unlicensed frequencies such as 315 MHz και 868 MHz. These bands are lower than the current popular 2.4ghz band, so LoRa’s path loss attenuation is better. Επιπλέον, 868 και 900 MHZ have much less interference than the highly dense 2.4 Ζώνη GHz. Επιπλέον, these low frequencies provide a lot of penetration in possible materials (brick walls, δέντρα, Εφαρμογές για κινητά και tablet ή smartphone μπορούν να χρησιμοποιηθούν για τον έλεγχο και την παρακολούθηση των διαδικασιών), so these bands lose less to obstacles than high bands.

RF modules can comply with defined protocols for RF communication, such as Bluetooth low power, Wi-Fi, και Zigbee, or they can implement proprietary protocols.
