The BeanBug VSB wireless earphone is a revolution in covert communications technology with a minute tube profile that will fit comfortably into very small ear canals for use in the most challenging special operations where high levels of discreteness are essential. The VSB Wireless Transmitter uses a novel, specialised audio signal modulation method which has been specifically developed to provide optimum performance in conjunction with the advanced digital signal processing implemented in the VSB Digital Wireless Receiver. The method used in the VSB transmitter/receiver combination delivers drastically reduced levels of audible interference and noise when used in areas of high AC magnetic field strength, typically from CANbus networks in vehicles, TDMI noise from TETRA terminals and Cellphones as well as mains-borne noise from electric motors, neon signs and power lines. As a result, the system achieves outstanding speech quality across the whole spectrum of covert applications where standard inductive devices are inoperable.
The modulation scheme uses only carrier frequencies within the audio band, is highly tolerant to frequency drift, transmit coil response and mismatch of operational frequencies between transmitter and receiver. The receiver is programmed to decode only audio signals modulated onto the carrier frequency thus making it immune from inductively-coupled noise sources. The system provides consistent performance over temperature and battery discharge level, while permitting compact construction. No matching or pairing between transmitter and receiver is required. The transmitter is entirely based on robust low-frequency electronics and is categorically not a radio frequency device. A range of compatible coupling systems are available for neck, chest and shoulder locations as well as a car interface that will support both baseband and digital inductive devices and the VSB system simultaneously.
