Wireless Communication Test Preparation
Course Introduction
Wireless Communication explores the principles, technologies, and standards that enable the transmission of information over air without physical connections. The course covers fundamental concepts such as radio wave propagation, modulation techniques, multiple access schemes, and channel coding. Students learn about the architecture of modern wireless systems including cellular networks, Wi-Fi, Bluetooth, and emerging 5G and IoT applications. Practical topics such as network planning, interference management, security issues, and system optimization are also addressed, equipping learners with both the theoretical background and applied skills needed for careers in wireless network design, implementation, and analysis.

Sample Questions
Q1) Describe the IEEE 802.11b standard.
Answer: The bandwidth of 2 Mbps for the 802.11 standard introduced in 1997 was not sufficient for most network applications. The IEEE body revisited the 802.11 standard shortly after it was released to determine what changes could be made to increase the speed. In September 1999 a new 802.11b amendment was added to the standard, which added two higher speeds (5.5 Mbps and 11 Mbps) to the original 802.11 standard (1 Mbps and 2 Mbps). Like the 802.11 standard, 802.11b uses the ISM band. The 802.11b standard can support wireless devices that are up to 115 meters (375 feet) apart. However, devices that are that far apart might not be transmitting at 11 Mbps. Radio waves decrease in power over distance, much like the sound of your voice: a person standing 1 meter away from you might hear you very clearly, whereas a person 60 meters away would have difficulty hearing you. Instead of completely dropping the signal if it falls out of range to transmit at 11 Mbps, the 802.11b standard specifies that the devices should drop their transmission speed to the next lower level (5.5, 2, or 1 Mbps). This allows devices to transmit farther apart but at slower speeds.
Q2) Access points are typically mounted on a(n) ____________________ to reduce interference from surrounding objects.
Answer: ceiling

Answer: Gain
Q2) There are several advantages of digital modulation over analog modulation. What are they?
Answer: Digital modulation makes better use of the bandwidth. It requires less power to transmit digital modulation than analog modulation. Digital modulation performs better when there is interference from other signals. Digital modulation error-correcting techniques are more compatible with other digital systems.
