ITPEC FE Subject A April 2024 Question 25
ITPEC FE Subject A April 2024 — Question 25 of 60
LTE (Long Term Evolution) — identify the mobile communication standard by its characteristics.
LTE is a mobile communication standard with three key features:
- •Packet switching — all communications use packet switching (unlike circuit switching in older networks)
- •MIMO — uses Multiple-Input Multiple-Output with multiple antennas for higher throughput
- •3GPP — standardized by the 3rd Generation Partnership Project
Why not others:
- (b) MAC (Media Access Control) — a sublayer of the Data Link Layer in the OSI model, not a mobile standard
- (c) MDM (Mobile Device Management) — enterprise software for managing employee devices, not a communication standard
- (d) VoIP (Voice over Internet Protocol) — a technology for voice transmission over IP networks, not a mobile network standard
Key rule: LTE = packet-only + MIMO + 3GPP. It is commonly known as "4G."
