Hospital critical medical devices immunity to EM by mobile phones Concerns on the effect of mobile phones on medical devices. Recent studies has shown that, using mobile phones have effect on medical devices. Many organizations around the world are very concern about the EMI and majority of them are working hard to ensure that EMC on medical devices is improved. But to improve the level of EMC is a length process and require tough regulation, therefore many health organization

Introduction The world lives a large evolvement in all life aspects. Everything moves in the comfort direction. One of these aspects is the technician aspect and it is an important part of everyone 's life as every thing around you become technician. In your room there is a TV, mobile, laptop...etc. Even most of kids ' toys became in need to a remote control. The wireless technology means no need to wires or cables. Wi-fi and Bluetooth are examples of that. Mobile wireless industry now is in the

The desire for instant communication is dated as far back as 1843 when Michael Faraday, a chemist, began researching whether or not space could conduct electricity. In 1865, a dentist and scientist, Dr. Mahlon Loomis invented communication by using the earth’s atmosphere as an electrical conductor. He flew two kites, made with copper and wires, hooked to two separate mountains. The U.S. Congress gave him a grant for $50,000. (Cell Phone Timeline Para 1, 2) The telegraph was built in 1866; also

4G wireless mobile communication networks are been specified to support display, battery and computational power etc. 4G wireless mobile communication networks should not focus on air interface and data rate, but instead cover advance wireless mobile communication networks and high speed wireless access system into different platforms. The era of new wireless communication is evolving and it will soon penetrate into daily life and change the way we live. The key concept is integrating the 4g capabilities

Mobile telephone call: A mobile device initiates a call by sending the number of the called device on the preselected setup channel. In this process, the the mobile device firstly checks whether the setup channel is idle by examining information that comes from the BS channel. If it finds that the setup channel is idle, the mobile device may transmit the information of number to the BS. The BS then sends the request to the MTSO. Mobile device paging: The MTSO then tries to complete the connection
