Document Summary
Identify a variety of uses for wans. Explain different wan topologies, including their advantages and disadvantages. Compare the characteristics of wan technologies, including their switching type, throughput, media, security, and reliability. Describe several wan transmission and connection methods, including dial - up, isdn, t. Carriers, frame relay, dsl, broadband cable, broadband over power line, atm, sonet, Describe wireless wan technologies, including 802. 16 (wimax), hspa+, lte, and satellite communications. Explore common problems with wan connections and ways to prevent internet connection problems. Wan: network traversing some distance, connecting lans, transmission methods depend on business needs. Wan and lan differences: lans connect nodes; wans connect networks, layers 1 and 2 access methods, topologies, media, lan wiring: privately owned, wan wiring: public through nsps (network service providers) Wan site: individual geographic locations connected by wan. Wan link: connection between one wan site and another site. Data terminal equipment (dte: customer"s endpoint device on the wan, communicates on the lan.
