Tutor-Marked Assignment, spring 2015
Q1. Investigating socio-technical system
You have studied in block three of the course materials the socio-technical system approach for investigating system failures. To demonstrate your understanding of this part of the course, we are asking you to make some investigations regarding a specific type of socio-technical system which is professional social networks as for example LinkedIn. For being able to complete this study, you should create an account in LinkedIn and start building your professional network. It is mandatory that you provide snapshot from your LinkedIn account to prove your participation in this social network. Then, answer to the following questions:
1. Draw the system map that you think representative for the given system. The system map must show at least two technical components, two social components, and two components that belong to the system environment.
2. Present briefly two processes of the given system.
3. Provide one major non-technical reason that may lead such system to failure?
Q2. Modulation and transmission
Consider the following constellation diagram at a receiver:
1. Briefly describe the reason for the difference between the symbols marked as “+” and the others around them.
2. What kind of modulation scheme is depicted in the above diagram? Clarify the reason.
3. Give one advantage and one drawback when using 16-QAM instead of QPSK.
4. Provide one major advantage and one major disadvantage of digital pulse amplitude modulation system.
Q3. Discovering Wi-Fi Network
You have studied in Block 1 the fundamental concepts, techniques, and mechanisms used in wireless communication in general and in more particularly in IEEE 802.11 standard. To in-depth your understanding, you will discover the Wi-Fi network in this question through real practical measurement. Therefore, you should install the Wi-Fi network discovery tool inSSIDer using the setup file attached to the TMA. Relevant information related to this software can be found in its homepage (i.e., MetaGeek - Optimize Your Wireless Environment). For being able to answer to the following questions, you should install and run the software on your mobile device. We recommend that you use laptop having Microsoft Windows as operating system and connected to the network through Wi-Fi.
1. What are the SSIDs of the access points (AP) detected by your mobile device? Prove your answer by providing snapshot of the table listing the relevant information of all the detected APs.
2. Provide the SSID and MAC address of the best AP (i.e., in terms of the quality of the received signal) to be connected to your mobile device if the access is granted?
3. What is the Wi-Fi protocol version used by the best AP and its maximum supported rate.
4. What is the channel number used by the best AP? Determine its lower and upper frequency.
5. Provide the graph of signal strength (in dBm) of every occupied channel. Is there any other less noisy channel that could be selected for the best AP? Clarify your answer.
6. Provide the graph of the signal strength (in dBm) variation over time.
7. Calculate in Watts the average signal power received by your mobile device from the best AP?
8. Which value of signal to noise ratio (SNR) is required for attaining the maximum data rate supported by the used version of Wi-Fi.
