Spectrum sharing is a method that allows multiple users or services to access the same radio frequency bands without causing interference. This approach maximizes the use of limited spectrum resources, which are essential for wireless communication technologies like cellular networks, Wi-Fi, and satellite communications. By enabling different entities to share frequencies, it promotes efficiency and innovation in the telecommunications industry. There are various models of spectrum sharing, including dynamic spectrum access and licensed shared access. These models help manage how frequencies are allocated and used, ensuring that priority is given to critical services while allowing others to utilize the spectrum when it's not in use. This collaborative approach supports the growing demand for wireless connectivity.
