IP and Mobility

Abstract

Being able to conduct one’s business while mobile has become one of the high growth market of recent times. During the 90’s cell phones became a mainstream product. The wireless telecommunication companies popularized cell phones by various technologies: AMPS, CDMA, GPRS, etc. Recently with the advent of the Internet, wireless data is becoming a very important part of conducting businesses. Network users can move about without restriction, access LANs from nearly anywhere and are liberated from conventional network connections. Practical uses for wireless networks are limited only by the imagination. Medical professionals can obtain patient records, real-time vital signs and reference data at the patient bedside without relying on reams of paper charts and papers. Factory floor workers can access part information and process specifications without knotting themselves up with wired network connections. Wireless connections with sensors (temperature, pressure, velocity, etc.) allows a remote engineer to diagnose and maintain the health and welfare of manufacturing equipment on environmentally hostile factory floor.
