The two-way remote RKE products can provide a certain distance monitoring range. The monitoring distance is one of the main performances of the two-way products. The key indicator of the communication distance is the link budget of the RF module (the difference between the power at the transmitting end and the sensitivity at the receiving end). Our rfm6x series mode can provide different link combinations. The transmission power covers 10dBm (10MW), 13dbm (20MW), 17dbm (50MW), 20dbm (100MW), 27dBm (500MW) and 30dBm (1W). The reception sensitivity has - 110dbm, - 120dbm and - 126dbm. The link budget ranges from - 120dbm at least to - 110dbm at the highest sensitivity, up to - 156dbm, leading the industry. Rf69 is the most cost-effective scheme. The following is the two-way architecture recommended by our company:

Recommended products:

1. Rf69, rfm69, rfm69h and other high-performance mainstream products;
2. Rf63 / 64 or rfm63 / 64 is recommended for customers with low distance requirements and high power consumption requirements.
