Research on Portable Frequency Hopping Wireless Data Transmission System

To remedy the complexity and sophistication of the Bluetooth equipments, a low-cost, high reliability, low power consumption and user friendly point to point wireless frequency hopping communication system was established. The system applies wireless communications chips nRF24L01 chips. DS/FH-SS techniques and adaptive frequency hopping technology, and enjoys the merits of excellent anti-jamming performance, good confidentiality, strong anti-interference, good mobility, and high accessibility. In addition, the system realized a low power consumption of around 70mW, which promises a good application to modern handheld wireless devices.
