Design of LTCC RF Modules for Communication Systems Circuit Diagram Long range radio communication is suitable for some IoT use cases; others require short range or cellular. It's an important factor in determining the radio system's range, because range is about reliably distinguishing signal from noise, not the distance that a given radio signal can travel (which is infinite). Radio noise is part of the After playing with Arduino and different kind of sensors for my garden, now I'm starting a new project for my free time. I want to work with RF communications because I need a long range device for my application, about 2 Km distance.. The idea is to make only an identification of which unit is, as a long range RFID but without RFID.. I mean some devices/units are placed somewhere, and after a RF Modules are low band radio frequency communication circuits that are used for transmission of digital data over small distances. Hence these modules are quite useful in making consumer electronics products or DIY projects for home or office environment. The 434 MHz RF module is a standard RF transmission product that is extremely popular and extensively used by hobbyists and the product
In this instructable you will learn how to communicate between Arduinos over a long distance up to 1.8km in open air. The HC-12 is a wireless serial port communication module that is very useful, extremely powerful and easy to use. First you will learn how to make a wireless instant messenger with the least effort possible.

Walkie Talkie using nRF24L01 RF Module. The main component of this project is the NRF24L01 RF module and Arduino Uno which is the brain
range of the RF links, the fewer concentrators are needed. Range considerations, narrowband versus coding gain solutions For a given output power (often defined by governmental RF regulations), the range of the RF link is determined by the data rate, i.e., lower rate provides longer range due to increased sensitivity for the receiver. Other answers have mentioned some good stuff about link budgets and ways to start if you'd like a rough guess at range. If you'd like to look at some decision-making processes behind long range communications that are pretty easy to understand, look up stuff on the Arduino forums on 25+ mile communications. There's plenty to go off of there. Make a long range Transceiver using ESP32 boards and send control commands as well as messages over a long range. Information about the nRF24L01 RF module.
