Call24 Wireless began in 1953 when Nick Reisenweaver, the chief engineer at WSJS television in Winston-Salem, N.C., began a sideline two-way radio business. The booming post-WWII economy helped Reisenweaver successfully grow his organization, as he met the dispatch communication needs of taxis, oil coal trucks and other mobile businesses. Now focusing solely on wireless communications, Call24 Wireless delivers solutions built on RCS’s decades of design experience, installation expertise and responsive service.
