I performed the fix properly by using the first file (''calibration rescue'') rather than the second file (''2016-3''). Now, the base station continues to blink green and nothing will recognize that it''s on. My PC only shows one Lighthouse and Steam VR only shows one connection. The odd thing is, if I ''scan for base stations'', it actually pulls ...
1.2. Classification of research into RES enabled BSs and networks. The research into renewable energy enabled BSs has been categorized into two distinct areas as depicted in Fig. 2, i.e., Green Base Stations and Green Cellular Networks. Fig. 2 also shows the classification of these BSs as per power grid connectivity.
