Interconnecting The Lans (Unit 4)

Assignment 4.1 (Interconnecting The LANs) Wireless Networking Questions and Problems Section 11-2 1.) List two advantages of communicate intercourse networking. * The WLAN provides increased flexibility and mobility for connecting to a network. * The drug exploiter doesnt have to look for a connection to guarantee 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 sample? * 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 dish out 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). * frequence hopping facing pages spectrum (FHSS). * Infrared * Orthogonal frequency share mul periodlexing(OFDM) 6.) cover the frequency spectrum for the DSSS channels in 802.11b wireless networking. * at that shopping mall are direct date 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 commun icate? * The FHSS requires that the tra! nsmitting and receiving units manage the Hopping Sequence (the order of the frequency changes) so that a communion link can be established and synchronized. 9.) What is the frequency condescend out use by 802.11a, and what modulation technique is used? * 2.4GHz, OFDM 10.) What is the utmost data rate for the 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
