Lab Exercise 1: Effect of SNR on Throughput and Delay Performance
This lab is geared towards understanding issues in wireless related to received signal strength (RSS) and SNR, and their effect on download times of web pages. The aim of this experiment is to observe the effects of SNR on the performance (in this case determined by download times of web pages of different sizes). The lab makes use of an IEEE 802.11 wireless LAN to transfer data.
Lab Exercise 2: Effect of Building Architecture on Throughput and Delay Performance
Wireless communications often use radio signals to transmit data via the air. Consequently, wireless network performance will vary when the end users are in different environments. The goal of this lab exercise is to study the effect of the environment on the performance for end users in different scenarios. You will observe the effects caused by partitions, floors, and the distance between the mobile station and the Access Point (AP).
Lab Exercise 3: CDMA Processing Gain
The goal of this lab is to give the students an understanding of the concept of Processing Gain (gp) and the concept of self-interference. Both of these are fundamental concepts of Direct Sequence Spread Spectrum (DSSS) Multiple Access Systems, such as IS-95A/J-STD-088. They are also fundamental considerations for most third generation digital cellular/pcs proposals.
Lab Exercise 4: CDMA System Communications with QUALCOMM Retriever
Students in this lab will acquire hands-on experience with a network tool for monitoring CDMA network operation and performance. Diverse conditions of the network and the associated messages will be observed and studied.
Lab Exercise 5: Bluetooth System Simulation using SystemView
This lab familiarizes the student with the radio system block of the Bluetooth short range wireless data system. The software simulation tool System View is used for the study.
Lab Exercise 6: AES
The purpose of this lab is to use Advanced Encryption Standard (AES) encryption and decryption routines in Matlab to study diverse security concepts. Using the routines the randomness of output and the avalanche effect, triple encryption using two keys and a brute force attack with partial knowledge of the key concepts will be studied.
