WIRELESS TECHNOLOGY
ABSTRACT
Wireless communication and data transmission are playing an increasing role in the critical care environment. Early anecdotal reports of electromagnetic interference (EMI) with intensive care unit (ICU) equipment resulted in many institutions banning these devices. An increasing literature database has more clearly defined the risks of EMI. Restrictions to the use of mobile devices are being lifted, and it has been suggested that the benefits of improved communication may outweigh the small risks. However, increased use of cellular phones and ever changing communication technologies require ongoing vigilance by healthcare device manufacturers, hospitals and device users, to prevent potentially hazardous events due to EMI.
INTRODUCTION:
The time has ripe for us to delve into the world of wireless technologies, and the first logical question in this direction seems to be asking the exact definition of wireless.
WHAT IS WIRELESS?
Put simply-a wireless technology is any technology in which wires were required wires have been eliminated in areas where wires were required before. Almost all wireless applications have been
HISTORY OF WIRELESS TECHNOLOGIES:
Though scientific world had been aware of both electricity and magnetism separately for a long time, the connection between the two had not been noticed until 19th century. Reports in the early 19th century about the connection were largely unnoticed by the scientific community. In 1820, Hans Christian Forested accidentally discovered that a current carrying wire caused a magnetic needle in a compass to deflect, and became the first record to evidence of the relationship between electricity and magnetism. Soon various theories of electromagnetism, notable ones being from Andre Marie Ampere, etc., were in circulation
