- Telestra is a company that is licensed to provide wired telecommunication services in Australia. The company has contracted Exetel to assist it with the selection and implementation of a new field service system. The goal is to provide service technicians with wireless access to the corporate network and a vast electronic library of technical manuals and schematic diagrams, which would reduce or eliminate the need for staff to carry a large number of books and drawings, especially while servicing equipment underground or when climbing on transmission towers. In addition, this means that the technicians would be able to immediately read and update the records for all the equipment, thereby avoiding massive amounts of paperwork as well as potential errors and omissions. However, the company is having trouble deciding on which technology to adopt- handheld cellular, tables with 3G/4G/5G access, or notebooks equipped with cellular cards. Exetel has asked you to help.
