Introduction to 940 IR

What is 940 IR?

The term "940 IR" refers to the International Radio Consultative Committee (CCIR) channel number 940, which is a frequency band used for various radio communication purposes. This band falls within the Ultra High Frequency (UHF) range and is specifically allocated for industrial, scientific, and medical (ISM) applications. The 940 IR band is widely used for wireless technologies such as radio frequency identification (RFID), wireless sensor networks, and other short-range communication systems.

History and Development

The 940 IR band has been in use for several decades, with its origins tracing back to the 1940s when the CCIR was established. Initially, the band was allocated for various radio services, including television, broadcasting, and mobile radio. However, with the evolution of technology and the need for more bandwidth for emerging applications, the CCIR reallocated the 940 IR band for ISM use. The development of the 940 IR band has been driven by the increasing demand for wireless communication in various industries. As technology advanced, the band has been utilized for more sophisticated applications, such as RFID technology, which has become an integral part of supply chain management, inventory control, and asset tracking.
