WIRELESS TRANSMISSION MEDIA

  1. 1. CHAPTER 3: COMPUTERNETWORKS ANDCOMMUNUCATIONSWireless Transmission Media
  2. 2. At the end of the lesson, student shouldbe able to:Identify various types of wireless communicationmedia such as: Infrared Radio waves Satellite
  3. 3. Infrared Using infrared light waves To communicate, infrared devices often must be within about 5 meters (15 feet).
  4. 4. Radio wavesIEEE 802.15.1 Bluetooth technology uses short-range radio waves to transmit data between two bluetooth devices The data transfers between devices at a rate of 1Mbps. To communicate, bluetooth devices often must be within about 10 meters (33 feet)
  5. 5. Radio wavesIEEE 802.11b/IEEE 802. 11g WiFi (Wireless Fidelity): The data transfers between devices at a rate of 11-54 Mbps. To communicate, WiFi devices often must be within about 30 meters (100 feet)
  6. 6. Satellite Is a space station that receives microwave signals from an earth- based station, amplifies (strengthens) are signal back over a wide area to any number of earth- based stations.
