Questions in: Rf Installation & Administration Engineer

Right Answer:
To work for GSM, you need to understand its architecture, including the Mobile Station (MS), Base Station Subsystem (BSS), Network and Switching Subsystem (NSS), and Operation Support Subsystem (OSS). Familiarize yourself with the signaling protocols like MAP and RANAP, and learn about frequency allocation, handover procedures, and network optimization techniques. Additionally, knowledge of RF principles, troubleshooting, and maintenance of GSM equipment is essential.

Right Answer:
A geostationary satellite is a satellite that orbits the Earth at the same rotational speed as the Earth, allowing it to remain fixed over a specific point on the Earth's surface. It is positioned approximately 35,786 kilometers (22,236 miles) above the equator.

Right Answer:
My academic project focused on designing and implementing a wireless communication system using RF technology. I researched various modulation techniques, built a prototype, and tested its performance in different environments to analyze signal strength and quality. This experience enhanced my understanding of RF principles and practical applications in real-world scenarios.

Right Answer:
Satellite systems typically use the Ku-band and C-band frequencies, with antennas such as parabolic dish antennas for signal transmission and reception.

Right Answer:
To find out radio failure, check the following:

1. Monitor the signal strength and quality indicators on the radio equipment.
2. Review error logs and alarms for any reported issues.
3. Perform a loopback test to verify the radio's functionality.
4. Check the connections and cables for any physical damage or disconnections.
5. Use diagnostic tools or software to analyze the radio's performance metrics.

Right Answer:
The limit of VSWR (Voltage Standing Wave Ratio) is typically 1:1 to 2:1 for optimal performance, with 3:1 being the maximum acceptable limit in many systems.
