ProfileCharles has 30 years of experience providing communication support within his organization. Prior to 1997 the organization consisted of one large geographic area serviceable by a self-supported LMR and mobile data infrastructure. As the organization expanded to five non-contiguous States LMR and mobile data were stretched to the limit. Over the previous ten years as the organization grew to include multiple States across the nation, self-supported mobile data gave way to enterprise data over cellular, and LMR has given way to Push-to-Talk over Cellular (PTToC). Charles currently maintains over 5000 mobile devices, and supports PTToC across the enterprise.
