How Spectrum Sharing Improves Channel Capacity
Increased Spectrem Explozation Efficiency
Studies have shown that man urban areas, licensed spectrem bands are underutized for signitant portions of thee day. Spectrem sharing allows secondary users to do fil these gaps, dramatically incrowing the e overall bits- per- second-per- Hertz metric. For example, the Citizens Broadband Radio Service (CBRS) band in the United States (3.5 GHz) uses a three-tier sharing frametriwork that has beene shown to more thene deuble thatre double the the cave ve ve ve un un t truf true comparam compue compue license g modelle.
