RFM69 FSK Transceiver Module

The RFM69 series wireless communication module is intended for global free application at the 434 MHz ISM band. It is a low-power, high-bandwidth module with low cost, stability, and product consistency, capable of transmitting data packets up to 300Kbps. The module has broad applications, including daily life activities that require wireless connection, industrial control, access control, attendance, surveillance, and security industries.

The RFM69HCW variant of the module communicates with a host microcontroller using an SPI and supports up to 256 networks with 255 nodes per network. It features AES encryption for data privacy and can transmit data packets of up to 66 bytes long.

The RFM69HCW operates at 915MHz frequency and can transmit up to 100mW at 300kbps. These values can be adjusted to match specific application requirements, with an option to maximize range by increasing transmit power and reducing data rate or reducing both for short-range sensor networks with low battery consumption.

The module can cover a considerable distance at full power, reaching over 500 meters in open air or transmitting from space to the ground using more complex antennas and modulation schemes. The RFM69 series has various models with different characteristics such as MCU, power amplifier, data interface, and packaging methods. These models can communicate with each other, meeting FCC/CE standards and satisfying clients' authentication needs.

1. What is the range of the RFM69 FSK Transceiver Module?

The effective range of the RFM69 FSK Transceiver Module is influenced by several factors, including the frequency utilized, power output, and antenna type. Based on research findings, using simple wire antennas, the RFM69HCW transceiver module can transmit signals up to 500 meters in a clear line of sight, while directional antennas and adjustments may extend this range up to 5Km. However, the range may be impeded by obstacles or interference in the surrounding environment, thus it is essential to consider the particular usage scenario and setting when estimating the RFM69 FSK Transceiver Module's range.

2. what is the maximum distance RFM69 FSK Transceiver Module can cover?

The RFM69 FSK Transceiver Module's maximum coverage distance is influenced by various factors, including the frequency used, power output, and antenna type. The RFM69HCW module, which can transmit up to 100mW at up to 300kbps, can communicate over several hundred meters with appropriate antennae. It operates on different frequencies, such as 434MHz, 868MHz, and 915MHz. However, obstacles and interference in the environment can affect the range. Therefore, when determining the maximum distance that the RFM69 FSK Transceiver Module can cover, it is crucial to consider the specific usage case and environment.
