This paper considers a basic question that many schools districts face in attempting to develop affordable, expandable district-wide computer networks that are resistant to obsolescence: Should these wide area networks (WANs) employ wireless technology, stick to venerable hard-wired solutions, or combine both. This publication explores the wireless option to WAN connectivity in educational facilities, examines its advantages and various limitations, and considers interface, security, and reliability issues. The paper also examines the aspects of a school district that make it a good candidate for utilizing wireless technology in creating a WAN. Final comments discuss ways to perform a building site survey before deciding to install a wireless WAN, and WAN infrastructure requirements and installation costs. (GR)
