Popis: In the National Broadband Plan released by the Federal Communications Commission (FCC) in 2010, it was predicted that with the ever increasing demand for data, the spectrum in 2009 will no longer be sufficient in 2013. The spectrum need was obtained based on the predicted mobile data traffic, number of cell sites and achievable spectral efficiency for the US in the FCC's report. In this study, predictions made by the FCC are compared with the achieved values from 2009 to 2016 in order to validate the required spectrum prediction. Furthermore, trends seen from 2009 to 2016 are used to predict when the required spectrum that satisfies the mobile data demand will exceed the entire radio frequency (RF) spectrum. According to the predicted mobile data traffic, number of cell sites and achievable spectral efficiency for the US, the entire RF spectrum will be fully used around 2035. Therefore, unlocking the visible light spectrum and deploying indoor/outdoor optical wireless systems would be a necessity for the next generation communication technologies in order to alleviate the spectrum crunch.
