1. Suppose a smart city would like to deploy a variety of sensors and is trying to determine the number of sensors it can deploy based on some design parameters, RF waveform characteristics, and channel access strategies. Below is a list of relevant parameters and characteristics: Each data point collected by each sensor is based on information quantized at 100 different possible levels. Each sensor sends a data point back to the smart city's centralized location 100 times per second. The spectral efficiency of the RF waveform is 2bps/Hz (applied to each sensor). The total RF bandwidth allocated to the sensors is 200 MHz. The channel-sharing scheme employed is frequency division multiplexing (FDM) with zero guard bands. a. (2pts) What is the maximum number of sensors that this system could support given the above parameters and characteristics? b. (8pts) There are 4 parameters that influence the answer in Part a: 1) number of quantization levels, 2) number of times per second a sensor sends a data point back, 3) spectral efficiency of RF waveform, and 4) total RF bandwidth allocated. Suppose we double each parameter individually. How does the answer in Part a change? Note, there will be 4 different answers in this part. Please show all your work to arrive at your answers. • Doubling only the number of quantization levels, all other parameters remain as in Part a. • ● ● Doubling only the number of times per second sensor sends data, all other parameters remain as in Part a. Doubling only the spectral efficiency of RF waveform, all other parameters remain as in Part a. Doubling only the total RF bandwidth allocated, all other parameters remain as in Part a. 1.
