Chapter 11 1. List two advantages of receiving focalize networking. It gives the User mobility in the workplace. less(prenominal) pricy than hard wiring, it would be cost-effective. 3.What is an ad hoc network? another(prenominal) landmark make to retrace an independent network 5.What be the quaternary physical tier technologies being apply in 802.11 piano tuner networking? Direct place dissemination spectrum (DSSS), oftenness hopping spread spectrum (FHSS), infrared, and irreverent frequency character multiplexing (OFDM) 7.Define a pseudo stochastic sequence as it applies to FHSS. Pseudorandom is the number sequence appears random but actually repeats. FHSS uses 79 channels (each 1 megacycle wide) in the ISM 2.4 gigacycle per second band. 9.What is the frequency ranged used by 802.11a, and what modulation technique is used? The 802.11a masters in the 5 GHz range. The 802.11a standard uses a technique called orthogonal frequency division multiplexing (OFDM) to transport the data everyplace 12 viable channels in the U-NII (Unlicensed case info Infrastructure). 11.Define MIMO as it appears to 802.11n. A space-division multiplexing technique where the data freewheel is split into multiple move called spatial streams. 13.What is the purpose of an entrance money point?

The advanceion point is a transmit/ pour down unit (transceiver) that interconnects data from the piano tuner LAN to the wired network. The access point provides 802.11 MAC spirit level functions and supports bridge protocols. 15.What is an railroad tie, and what is its purpose? The verge association is used to describe that a wireless attachment has been obtained. Access points use the association to build a perimeter card of users on the wireless network. 19.In what frequency band does Bluetooth blend? The wireless technology called Bluetooth is base on the 802.15 standard. 21.What is a piconet? A piconet is an ad hoc network of up to eight Bluetooth devices such as a computer, mouse, headset, earpiece, and so on. 23.What is the...If you requirement to get a sentience essay, order it on our website: Orderessay
