Electronic equipment is usually contained in metallic/conductive boxes. Explain why, describing how this works. Q3 (a) (b) When does a connection between two electronic components such as a track on a printed circuit board cease being considered as a short circuit? Explain your answer clearly, and hence or otherwise, estimate the maximum dimensions of components within a mobile phone operating at 1.8 GHz if it is to act as a lumped element circuit. Explain why, as the frequency is increased, a component which acts as an inductor at low frequency, ultimately has a capacitive reactance. (c)

A GSM operator leases 7 MHz of spectrum (i.e., 7 MHz each in the uplink and the downlink), and estimates that a D/R of at least 4 is required. If the cell radius, R, is 2 km (assume hexagonal cells), determine the Erlangs per square kilometer for the network, for a target blocking probability of 1%.
As explained in Section 3.2, urban environments are more obstructive to radio waves than rural environments, leading to reduced base station (BS) range. This can, however, be of benefit in urban areas where there is high demand for cellular communication services. Briefly explain why reduced BS range can be advantageous in this context.

In line-of-sight radio system, losses are mainly due to free space path loss (FSPL). FSPL is proportional to the square of the distance between the transmitter and receiver as well as the square of the frequency of the radio signal. Observe the FSPL for the situation below. a) For fixed frequency at 2600 MHz, calculate and sketch the graph of FSPL at the range of 1 km, 10 km, and 30 km. b) For fixed frequency at 5.8 GHz, calculate and sketch the graph of FSPL at the range of 1 m, 10 m, 100 m and 1 km.
4. One of the key factors that drives the design of a satellite based personal communication system is the size and allowable power of the handset transmitter. If the handset is limited to a three-quarter watt (0.75W) transmitter, and has an antenna with a gain of only 1.5 dB, what is the maximum range over which we can close the uplink with an acceptable margin (10 dB)? Givens: a) satellite antenna diameter of 1.0 meter (.65 efficiency), b) transmitter frequency 900 MHz, c) bandwidth 150 KHz, and d) noise temperature 500K.
Briefly explain which factors are important for planning a Wireless LAN design for a campus network.
A simple point-to-point microwave transmission link has no redundancy. Failure of the link will result in an outage. Therefore, typical microwave transmission links are designed with redundancy. Explain the following redundancy techniques 1+1 Hot Standby (HSB), 1+1 Space Diversity (SD), and 1+1 FD (Frequency Diversity).please explain.
"A transmission line with negligible attenuation has L = 0.15 uH/ft and C = 0.1 nF/ft and is typically operated at 100 MHz. What is the velocity of propagation (in 10^8 m/s) of the signal along this line? Enter only the numerical value. No need for the unit. Use four decimal places (if the answer is not an integer). For example, the calculated value is 3x10^8 m/s, then enter 3."
