In the radio communication system, it is impossible to transmit signals directly from transmitter to receiver due to few drawbacks including the height of antenna, interference, poor receiver’s reception, and effectiveness of the power radiated by the antenna’s transmitter itself. Explain the drawbacks due to height of the antenna radio communication system by giving a real example and situation.

Q2. Consider a microwave transmit-receive radio-link system. Given that, the transmitter power is Pt-5W at a carrier frequency of 6 GHz and the transmitter antenna gain is 40dB. Assume that the receiver antenna has a diameter of 60cm and has an aperture efficiency of 65 %. a) b) c) d) Determine the power density at a distance of 50m from the transmitter antenna. Find the directivity of the receiver antenna. Find the operating wavelength and the far-field distance of the...
As a communications system engineer, you are asked to setup a communication system to serve a distance of 100m using an access point transmitting signals with power 20dBm at the frequency 2.4GHz. The antennas used at the transmitter and receiver side have the gains shown in the picture below. The coaxial cables used to interface the systems to the antennas have losses shown in the picture below What is the received signal power in dBm at the input of the...
I need help with the case W16165 SOMEBODY STOP THE RADIO STAR: JIAN GHOMESHI AT THE CBC Questions: What negative behavior is attributed to Ghomeshi? What was the impact of his alleged behavior on Q employees? Why did the employee get together to compile the red sky presentation for Groen and Noorani? What else could they have done. If is is true that Goneshi treated Q staff extremely poorly over a long period of time (e.g. from April 2007 to...

STEP 1: In your own words define problem employees and the categories they may fall into. For the second or last paragraph provide your opinion on which employee type is the most difficult. DEFINITION : I think that "problem employees" are employees that either directly or indirectly hinder the organization's mission or vision, and break down into roughly four categories. In general, problem employees can be classified into two broad categories - employees creating problems for the organization and employees...
