  1. 3.Transmission Media - Wireless -Cabling System

  2. Wireless Topologies • Ad hoc topology: Connects two or more wireless computers communicating with each other only • Infrastructure network: Connects wireless computers communicating with a network access point that provides access to a standard cabled network

  3. IEEE 802.11 Standards • IEEE 802.11a. Speeds of 1 to 2 Mbps • IEEE 802.11b. Speeds of 5.5 to 11 Mbps

  4. Cabling System • Coaxial cable • Fiber optic • Twisted pair
