The stability of the communication is very important as well as the accuracy of the impact sensor is the also most sensitive part. If wireless system goes wrong during competition, it may cause serious problem and trouble in the event.
KP & P receiver, dual PHY form IEEE 802.15.4 compliant and use the 2.4GHz frequency band, and the data transfer rate is 250kbps. Used for a long period of time to minimize the power consumption, has a big advantage. 30m in the local area received less radio interference can maintain a very reliable communication within.
