Wireless Networking
Questions and Problems
Section 11-2
1.) List two advantages of radio intercourse networking.
* The WLAN provides increased flexibility and mobility for connecting to a network.
* The user doesnt have to look for a connection to plug into; also, the expenditure of pulling cables and installing wall plates required for wired networks behind be avoided.
2.) What are the three areas defined for the IEEE 802.11 standard?
* 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 Service 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).
* Frequency hopping spread spectrum (FHSS).
* Infrared
* Orthogonal frequency share multiplexing(OFDM)
6.) Describe the frequency spectrum for the DSSS channels in 802.11b wireless networking.
* at that place are direct sequence 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 know the Hopping Sequence (the order of the frequency changes) so that a communication link can be established and synchronized.
9.) What is the frequency come out used 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
