AI Technical Summary
Conventional baby monitors face issues with high power consumption due to constant processor activity, limited connectivity, and susceptibility to interference from other electronic devices, particularly in the 2.4GHz ISM band, which affects battery life and reliability.
Implementing a dual-mode communication system using Wi-Fi modules with a first processor handling network messages in a sleep mode and a second processor for data processing, allowing direct and indirect communication paths through an access point, and employing DSSS and OFDM modulation schemes for efficient power management and reduced interference.
The system significantly reduces power consumption, extends battery life, enhances connectivity by enabling Internet access, and improves reliability by minimizing interference, allowing seamless audio and video streaming with extended operating time.
