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...

You have been hired by a Fortune 500 aerospace company to work on an integrated product development team (IPDT) tasked with designing a communications pod that mounts on top of the fuselage of a wide-body jet. The pod consists of an antenna, transmitter, receiver, controller, housing, coolant pump, power supply, and vibration dampening equipment. Name the type of engineer you would expect to find as the lead engineer for this project and explain why
Explain why in detail/using equations if possible!
Designing a High speed Wireless Data Link Line of Sight Link Budget Analysis Several major factors that can impact the performance of a radio system are Available/permitted output power e Bandwidth, . Receiver sensitivity Antenna gains In this case study, the students will be required to calculate the link budget for a LOS Wireless link. Read through the following to understand some of the aspects and elements that need to be considered when calculating a Link Budget. If the estimated/calculated...
This is a preliminary heat exchanger question. Using the Reynold's Transport Theorem, conservation of energy, and heat convection fundamentals, explain the heat flow in detail for the following system depicted below. Use your own words and basic equations when necessary. You are not expected to present any numerical results. List & define all the geometric and physical variables you need in your narrative Hint: There are two separate flow paths and flows! warm warmed fluid out fluid in cold fluid...
I11.8. As you know, data from satellites are used to locate a GPS receiver, and data from seismic stations are used to locate an earthquake. Explain the physical/mathematical principle which both methods have in common. (No need to explain the different technical details; just concentrate on the underlying fundamentals. But do point out what the respective input data are.)
The following statement is either accurate as written or contains some errors. You need to rewrite as an accurate statement. Be sure that you do not change the material the sentence is about. Highlight or underline any changes that you make to the statement: Yeast have one origin of replication on their circular chromosome that creates two replication forks.
You have seen an example of solving Navier-Stokes equations for flow in a circular tube of radius R (Poiseuille flow). In those instances, the tube is horizontal, and flow is along the horizontal axis (z-axis in cylindrical coordinates). Now imagine if the tube is turned 90° so that the flow is downward and is now parallel to gravity g (A) Start with the Navier-Stokes equations, set up the problem, and clearly indicate what assumptions are used in your simplification of...
