E34-2G4H20D is a 100mW wireless transceiver module, which operates at 2.4-2.518GHz. The outstanding advantages of this module is concentrated power densities, long transmission range, automatic frequency hopping & strong anti-interference, TTL level. Automatic frequency hopping technology is in order to ensure the communication of the secret and anti-interference, compared with fixed frequency communication, frequency hopping communication is more covert and difficult to be intercepted. Frequency hopping communication also has a good anti-interference ability, even if there are some frequency interference, still can communicate on the undisturbed frequency point. The module has the function of data encryption & compression. The data of the module transmitted over the air features randomness. And with the rigorous encryption & decryption, data interception becomes pointless. The function of data compression can decrease the transmission time & probability of being interfered, while improving the reliability & transmission efficiency.
