article: History of radio Marconi transmitting the first radio signal across the Atlantic. This has been used in biomedical situations such as pacemakers, as well as for short-range Rfid tags. Satellite Communciaiton, infrared Communication, infrared wireless communication communicates information in a device or systems through IR radiation. Baltimore - Headquarters 1803 Old Sulphur Spring Road, baltimore, MD 21227, phone: (410) 247-4737. 21 Wireless Sensor Networks are responsible for sensing noise, interference, and activity in data collection networks. A broadcast sends information over long distances at up to two megabits/Sec (AM/FM Radio). It was initially used from about 1890 for the first radio transmitting and receiving technology, as in wireless telegraphy, until the new word radio replaced it around 1920. These networks need to be protected with passwords for the purpose of security, otherwise it will access by others. Wireless Communication Based Projects Therefore, this is all about Types of wireless communication, these networks are one of the important technologies in the telecommunications market.
