Interconnecting The Lans (Unit 4)

Assignment 4.1 (Interconnecting The LANs) Wireless Networking Questions and Problems Section 11-2 1.) List two advantages of radio set intercourse networking. * The WLAN provides increased flexibility and mobility for connecting to a network. * The substance abuser doesnt have to look for a connection to quid into; also, the expenditure of pulling cables and installing wall plates required for pumped-up(a) networks behind be avoided. 2.) What are the three areas defined for the IEEE 802.11 beat? * Physical, mack (Media access control), Wireless Management Protocol 3.) What is an ad hoc network? * An case-by-case Network 4.) What is the purpose of an Extended benefit Set? * The use of ninefold access points to extend user mobility. 5.) What are the four corporal layer technologies being uses in 802.11 wireless networking? * Direct duration pass around spectrum (DSSS). * absolute frequency hopping pass o ut spectrum (FHSS). * Infrared * Orthogonal frequency share mul pinchlexing(OFDM) 6.) key out the frequency spectrum for the DSSS channels in 802.11b wireless networking. * at that business office are direct taking over spread spectrum (DSSS), frequency hopping spread spectrum (FHSS), infrared, and orthogonal frequency division multiplexing (OFDM). 7.) Define a pseudorandom sequence as it applies to FHSS. * The sequence appears to be random but in fact does repeat, typically after some lengthy tip of time. 8.) What must the FHSS transmitting and receiving units chicane to communicate? * The FHSS requires that the transmitting and receiving units hump the Hopping Sequence (the order of the frequency changes) so that a talk link can be established and synchronized. 9.) What is the frequency enumerate out use by 802.11a, and what modulation technique is used? * 2.4GHz, OFDM 10.) What is the utmost data rate for t he following: a.802.11b -! > 54 Mbps b.802.11a -> 11Mbps c.802.11g -> 54 Mbps...If you compliments to get a full essay, order it on our website: OrderCustomPaper.com
