TAILIEUCHUNG - Chapter 4 Transmission Media

Guided - wire Unguided - wireless Characteristics and quality determined by medium and signal For guided, the medium is more important For unguided, the bandwidth produced by the antenna is more important Key concerns are data rate and distance | William Stallings Data and Computer Communications Chapter 4 Transmission Media Overview Guided - wire Unguided - wireless Characteristics and quality determined by medium and signal For guided, the medium is more important For unguided, the bandwidth produced by the antenna is more important Key concerns are data rate and distance * Design Factors Bandwidth Higher bandwidth gives higher data rate Transmission impairments Attenuation Interference Number of receivers In guided media More receivers (multi-point) introduce more attenuation * Electromagnetic Spectrum * Guided Transmission Media Twisted Pair Coaxial cable Optical fiber * Twisted Pair * Twisted Pair - Applications Most common medium Telephone network Between house and local exchange (subscriber loop) Within buildings To private branch exchange (PBX) For local area networks (LAN) 10Mbps or 100Mbps * Twisted Pair - Pros and Cons Cheap Easy to work with Low data rate Short range * Twisted Pair - Transmission Characteristics .
