Spectera System

Sensing Capabilities - Audio detection and transmission

Spectera devices (Base Station, DAD, SEK) build audio transmission system for professional use. Once paired, SEK mobile devices can transmit audio signals captured by a connected microphone over radio frequencies. Due to its bi-directionality, the SEK is able to receive audio signals from DAD and the sound comes out of the headphones, if any connected. Here how it works:

Transmission:
  1. The SEK picks up sound from microphone and turns it into electrical signals.
  2. These signals are then prepared for transmission by boosting and modifying them.
  3. The signals are sent over radio waves to the DAD Antenna.
  4. The DAD antenna changes the radio back into electrical signals and sent them to the Base Station for further audio processing.
Receiving:
  1. The Base Station forward audio signals to the DAD Antenna.
  2. These signals are then prepared for transmission by boosting and modifying them.
  3. The signals are sent over radio waves to the SEK mobile devices.
  4. The SEK changes the radio back into electrical signals and at a further stage, sound will be directed to connected headphones.
