1. The wireless conference signal base station connects the conference host and units through secure wireless communication using 128 bit AES Rijndael encryption technology.

2. Contains powerful built-in wireless audio transmission protocols, utilizing a large number of coexistence mechanisms to allow units to avoid interference or interference from other 2.4 GHz wireless systems.

3. Adaptive frequency hopping, forward error correction and retransmission mechanism, with the characteristic of error concealment.

4. Using one of the three non overlapping carriers in the 2.4GHz frequency band, which is a common frequency band and does not require authorization.

5. The radiation diameter of wireless voting base stations can reach up to 80 meters (in a non-interference visual environment).
