TranQuiL system boosts radio telescope protection against wireless interference

A new system called TranQuiL is set to improve protection for radio telescopes in areas where wireless signals are restricted. These zones, known as Radio Quiet Zones (RQZs), shield sensitive equipment from interference caused by everyday devices. Researchers have now developed a way to detect and locate unwanted signals more accurately than before. The system was introduced by a team led by Bansal et al. in a study published in Radio Science. Their work forms part of AGU's Special Collection on Radio Frequency Interference for 2024. TranQuiL specialises in identifying interference from Bluetooth and Wi-Fi sources over long distances.

For Bluetooth signals, the system achieves a median accuracy of 13.2 metres across a range of 450 metres. With Wi-Fi, it extends detection to 950 metres while maintaining the same level of precision. These improvements surpass existing methods, making enforcement in RQZs far more efficient.

By reducing downtime caused by interference, observatories can now focus on capturing faint cosmic signals without disruption. The technology ensures that astronomical research remains free from terrestrial wireless noise. The research, cited as Bansal et al. (2026), highlights TranQuiL's role in strengthening RQZ enforcement. Its ability to pinpoint interference sources with high accuracy allows observatories to operate with fewer interruptions. This advancement supports ongoing scientific efforts to study the universe without signal contamination.
