SBC uses both cell's and SMR radios in most of the south. Some of them are even using the Southern Linc iDEN system. They sometimes operate in areas where cellular coverage is spotty at best, and since they are involved in not only setting up/tech checking the Cingular system, but also many other communications needs, they need multiple communications needs. Just so folks know, Cingular is the mobile/cell phone division for Bellsouth Telecommunications in a lot of the south. And to put a cap on faulty logic,.. if you think that since they are a cell company just use cells for coms,.. Bellsouth is a phone company, so why would they need a Conventional Radio System, or heck even a TRS? Because of the needs of the company. Why tie up phone/cellular systems with extra needs when you can get the job done on regular radio networks.
