Wireless Communication Modems
Wireless communication modems are devices that carry serial communication data or control signals between points where cable cannot be run, over the GSM network or an RF or LoRa radio link. They are used for pump control between a well and a tank, for reading remote meters and analyzers, and for connecting RS-485 devices in scattered sites to a central point. Tense GSM and RF well-tank communication sets consist of a transmitter and a receiver; GMT G-9921 and G-LORA-485-D10 converters, which carry the serial line wirelessly using a 4G GSM modem, also belong to this group. Choose the communication medium (GSM, RF or LoRa) by the distance between points and operator coverage; compare the serial interface (RS-232, RS-485 or RS-422), the transmission distance and the contents of the set. Some models in the product data specify transmission distances of up to 5 km and up to 10 km; the actual range depends on terrain, obstacles and antenna placement. RF and LoRa converters work with at least two devices as a pair and do not use a SIM card; they do not replace a GSM modem that provides remote access over an operator network.

How to choose Wireless Communication Modems
Wireless communication modems are devices that carry serial communication data or control signals between points where cable cannot be run, over the GSM network or an RF or LoRa radio link. They are used for pump control between a well and a tank, for reading remote meters and analyzers, and for connecting RS-485 devices in scattered sites to a central point.
- Separate sensing, motion control, logic processing and operator interface requirements.
- Select signal type, supply voltage, communication protocol and I/O count for the machine network.
- Verify housing size, sensing distance and PNP/NPN output polarity against the PLC input card.
