[PPRAANet] CDOT experiments with cell coverage problems using Citizens Band Radio Service

CDOT finds a low-cost answer to its cellular dead zones, making canyon calling possible
South Korean technology could offer better coverage and substantial cost savings

Since last fall, the department has been testing a South Korean communications technology, supplied through a Denver startup called Eucast Globa <https://www.denverpost.com/2022/08/01/celluar-denver-technology-5g-digital-divide/>l, along a problematic four-mile stretch of highway from the Bakerville to Silver Plume exits, east of the Eisenhower Tunnel, where the terrain makes it difficult for cellular signals.

Eucast boxes are relatively small and the tests proved they were weather resistant. They attached to existing light poles, drawing on the nearby power supply. Once powered, they connect to nearby cellular or satellite networks or tap into fiber optic lines and can handle about 200 devices. But their real power comes in using a spectrum the FCC recently opened up for public use called Citizens Band Radio Service or CBRS.
