This work covers the ten leading wireless technologies in use today - cellular phones, personal communications, cordless phones, pagers, private land-mobile radio, radio data networks, WLANS, microwave relay, satellites and meteor burst - and their advantages and disadvantages for applications in intelligent transportation systems. A survey of the current literature is included. This work is intended for engineers and managers who want to improve their understanding of key wireless technologies and their application to transport management. It should also be useful for engineering/communications graduate and undergraduate students.
