Recruitment process for Wireless PSI & Radio Operator / Technical Operator & Police Sub Inspector in Motor Transport (MT) are generally organized by Gujarat Police Recruitment Board (GPRB) to recruit Police Sub Inspector (PSI) for wireless branch. This exam is totally different from Armed and Unarmed PSI Recruitment, so don’t be confused with the same.
