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

The flow of broadcast in satellite communication involves transmission from the source to the satellite, uplink transmission to the satellite, and downlink transmission to the receivers.

• Broadcast transmission starts at the source, which can be a television station or a content provider.

• The source transmits the broadcast signal to the satellite using a transmitter.

• The satellite receives the signal and amplifies it before retransmitting it back to Earth.

• The uplink transmission ...read more

Transport layer ensures reliable data transfer between end systems. Network layer provides logical addressing and routing.

• Transport layer segments and reassembles data into a stream of packets.

• Transport layer provides error checking and flow control.

• Network layer determines the best path for data to travel from source to destination.

• Network layer uses logical addressing to identify devices on a network.

• Examples of transport layer protocols include TCP and UDP.

• Examples of netw...read more

Scripts used in telecom are programming codes that automate tasks and configurations in network devices.

• Scripts are used to automate repetitive tasks in telecom networks.

• They can be written in languages like Python, Perl, or Bash.

• Scripts can be used for tasks like network configuration, monitoring, and troubleshooting.

• For example, a script can be used to automatically backup configurations of network devices.

• Another example is using a script to generate reports on network per...read more

The OSI model is a conceptual framework for understanding network communication.

• OSI stands for Open Systems Interconnection.

• It has 7 layers, each with a specific function.

• The layers are: Physical, Data Link, Network, Transport, Session, Presentation, and Application.

• Each layer communicates with the layer above and below it.

• Frequency Modulation (FM)

• Phase Modulation (PM)

• Quadrature Amplitude Modulation (QAM)

• Pulse Code Modulation (PCM)

Interference types in transmission engineering include external, internal, and co-channel interference.

• External interference: caused by external sources such as other radio signals, power lines, or electronic devices.

• Internal interference: caused by components within the transmission system, such as faulty equipment or improper grounding.

• Co-channel interference: occurs when multiple signals on the same frequency interfere with each other, leading to signal degradation.

• Example...read more
