Bluetooth 5.0/4.2 Ultra-Long Range Bluetooth Module Solution:

Bluetooth is a wireless technology, and radio is a form of electromagnetic radiation. In terms of communication, the maximum communication range refers to "the furthest distance at which data can be correctly extracted from received signals," rather than "the distance over which the signal can still be detected."

Compared to Bluetooth 4, the Bluetooth 5 LE Coded physical layer can extend communication intervals to about four times, without requiring increased transmission power, thereby reducing power consumption—a crucial advantage.

Extended transmission intervals will support coverage across the entire home and building, resulting in more stable and reliable connections. Faster speeds will bring higher responsiveness and performance to the devices. The significant increase in broadcast data transmission volume will greatly enhance the transmission capability of connectionless communication-based solutions.

With the expansion of the spectrum, Bluetooth 5 also increases the transmission range. How does it achieve this? The answer lies in the encoding method! Through half-rate and eighth-rate encoding, the half-rate encoding offers approximately 4-5dB flexibility and nearly double the range at 500kbps; while the eighth-rate encoding provides 12dB flexibility at 125kbps, extending the transmission interval to four times.
