Updated 20 May 2024

Q1. What are different types of transmission losses. What is VSWR. What is difference between packet Loss , Latency and Jitter

Ans.

Transmission losses include conductor losses, dielectric losses, radiation losses. VSWR is Voltage Standing Wave Ratio. Packet loss, latency, and jitter are different types of network performance issues.

Transmission losses: conductor losses (resistance in conductors), dielectric losses (energy lost in insulating materials), radiation losses (energy radiated into space)
VSWR (Voltage Standing Wave Ratio): measure of how efficiently radio-frequency power is transmitted from a po...read more

Q2. Types of MW Equipments, types of faultin RAN and Mw

Ans.

MW equipments include radios, antennas, and transmission lines. Common faults in RAN and MW include interference, hardware failures, and alignment issues.

MW equipments: radios, antennas, transmission lines
Types of faults in RAN: interference, hardware failures, alignment issues
Types of faults in MW: signal degradation, weather-related issues, alignment problems

Q3. Explain 4g and 5g architecture. What is SGW

Ans.

4G and 5G architecture differ in terms of technology and capabilities. SGW stands for Serving Gateway in LTE networks.

4G architecture is based on LTE technology, while 5G architecture is based on NR technology.
4G networks use EPC (Evolved Packet Core) for communication, while 5G networks use 5GC (5G Core).
SGW (Serving Gateway) in LTE networks is responsible for routing and forwarding user data packets.
In 5G networks, SGW functionality is split between UPF (User Plane Function...read more
