IT Wirless Technologies - seek ExamplePower conform tod (d = 8km) is 10 times greater than power received (d = 25km)(v) termination no of UWB devices in urban center = 2 * 1 million zero(prenominal) of UWB devices in town 2 * 6000 = 166.67No. of UWB devices in city is 167 times greater than that in the townb) (i) SolutionFrom Tables 3 and 4 it is seen spy that, the maximum tolerable power density radiated by the UWB devices is higher in town compared to that in the city. That is, at the same percentage of activity, the maximum tolerable hang-up limit is lower in the city when compared to the town. This implies that, city is the greater source of prophylactic and thus has tighter restrictions.(ii) SolutionYes, the answer to character reference b) (i) is consistent to that of the answers in part a) (iv) and (v). Because, from part a) we know that the number of UWB devices inthe city are 167 times greater to those in the town. Which implies theinterference by 1 % of the devices in city will much greater than theinterference by 1% of the devices in the town. Also as the city covers widerarea, the signal that has to travel through the interference for a bimestrial distance(in the city) will have greater path loss and hence lower power received.(iii) SolutionFour factors that might effect the accuracy of the prediction of UWBinterference are,1) If the UWB senders are inst in alled outdoors2) If the UWB devices are all ON at the same time.3) If the UWB devices are distributed in clusters ad not randomly.4) If the UWB devices are operated in a pre-designed manner and not at random times.(iv) SolutionIf UWB devices transmitting at -41.3 dBm/MHz over the...Which implies theinterference by 1 % of the devices in city will much greater than theinterference by 1% of the devices in the town. Also as the city covers widerarea, the signal that has to travel through the interference for a agelong distanceDetect and Avoid technique can be used only for those RAS signals whose frequencies do not fall into the frequency band of the UWB devices. The minimum power (of the RAS signal) that can be sight by the detectors to avoid the RAS signal also matters.Streaming Video means to continuously receive and display video to the end user while it is being transmitted by the source. This means that cyclosis video requires higher bandwidth and faster entropy rate.802.11n is used for streaming video around the home as it offers a higherBandwidth and highly reliable connection that can reach throughout the home and is compatible with various network configurations that might be used athome.Base send off is a transmitter that operates within a given frequency channel andantenna sector and is responsible for transmitting data to the subscriber stationand is equipped to control the subscriber station. Base Station can transmit dataindependent of other stations, but will depend on the channel if it is a TDDchannel.Subscriber Station is a transceiver that recei ves data from the base station andcan also send requests to base s
