Frequency Band
A specific range of radio frequencies used for transmitting signals, like different channels on a radio or TV.
TECHNICAL DEFINITION
A Frequency Band is a continuous range of electromagnetic frequencies, typically allocated by regulatory bodies (e.g., ITU) for specific communication services (e.g., satellite, cellular) to prevent interference and ensure efficient spectrum utilization.
BACKGROUND
The space industry of India is predominantly driven by its national space agency ISRO. The industry includes over 500 private suppliers and other various bodies of the Department of Space (DoS) in all commercial, research and arbitrary regards. Since the Indian space sector was opened up to private sector in 2020, numerous private space companies have emerged, working on various aspects of space exploration. In 2023, the space industry of India accounted for $9 billion or 2%–3% of the global space industry and employed more than 45,000 people.
