Handover
Handover is a critical process in telecommunications where the responsibility for a mobile phone call or data connection smoothly transfers from one cell tower to another as a user moves around. Think of it like a relay race where runners pass a baton - except here, it's your phone call being passed between towers without dropping. This process happens automatically many times daily and is essential for keeping people connected while they're moving. When someone mentions handover in their resume, they're typically referring to their experience with managing, optimizing, or troubleshooting this process in mobile networks.

Example Interview Questions
Senior Level Questions
Q: How would you improve handover performance in a congested urban area?
Expected Answer: A senior engineer should discuss analyzing network data, adjusting cell parameters, considering factors like building density and user patterns, and implementing solutions like small cells or parameter optimization.
Q: Explain how you would manage handover between 4G and 5G networks?
Expected Answer: Should demonstrate understanding of inter-technology handover challenges, network planning considerations, and strategies to ensure smooth transitions between different network generations.
Mid Level Questions
Q: What are the main causes of handover failures?
Expected Answer: Should be able to explain common issues like signal strength problems, interference, incorrect parameter settings, and network congestion, along with basic troubleshooting approaches.
Q: How do you monitor handover success rates?
Expected Answer: Should describe key performance indicators (KPIs), monitoring tools, and basic analysis methods for tracking handover performance.
Junior Level Questions
Q: What is a handover and why is it important?
Expected Answer: Should explain the basic concept of call/data transfer between cell towers and its importance for maintaining mobile connections while users move.
Q: What are the different types of handovers?
Expected Answer: Should be able to describe basic types like soft and hard handovers, and explain the simple differences between them.
