Regarding the Negative voltage being suplued to BTS particularly in Ericsson BTS. The reason is
1: This prevents corroson.
2: This protects BTS during Lightining.
3 and the main reason, the Noise generally runs to + terminal of the Battery so we use -ve terminal in order to increase the speech level quality.
