Multiplexing
Project description
Complete the following questions in an MS Word Document in APA format. Double space your work and place
in 12 point font using Times New Roman. You must include both a separate cover and reference page.
1. Cellular device networks must support a large number of users from each wireless tower and so rely
extensively on multiplexing technologies. Research current cellular device technology and describe at
least three different types of multiplexing employed. You should both explain the multiplexing technique
in general and describe how it is employed within the cellular device network.
2. Can you compress a set of bank statements using JPEG compression? Explain.
3. Noise, cross-talk, and other forms of interference are a significant issue in any communications
infrastructure. Compare and contrast how this problem would manifest for analog data transmitted with
an analog signal, for analog data transmitted with a digital signal, for digital data transmitted with an
analog signal, and for digital data transmitted with a digital signal. Be sure to compare the quality of the
resulting communication as well as the physical description.
4. Compare and contrast parity check, checksum, and hamming code. Include both error detection and
error correction considerations.
5. For the network that you have chosen to characterize, identify at least two specific points where you
think noise or other signal integrity issues may be impacting the infrastructure. For each, identify at
least one appropriate strategy for error prevention to address the issue.
