ITPEC IP October 2025 Question 33
Topic: NetworksAlso asked in Spring 2020 and April 2022
Which of the following mobile communication systems not only offers higher communication speed than LTE, but also allows more devices to connect and has less lag time?
Explanation
5G — the fifth-generation mobile system: faster than LTE (4G), with more connected devices and lower latency.
5G is designed around three goals, the three in the question:
- •Enhanced mobile broadband: peak rates of several Gbit/s, far above LTE
- •Massive machine-type communication: many IoT devices connected at once in one area
- •Ultra-reliable low-latency communication: delays of about a millisecond, for uses such as remote control of machines
Answer (d)
Why not others:
- •(a) Block chain — a distributed ledger that links blocks of transactions by hash values; not a communication system
- •(b) MVNO — a mobile virtual network operator, a company that offers mobile service over another carrier's network; a business form, not a technology
- •(c) 8K — a video resolution of about 7680 × 4320 pixels; 5G can carry it, but it is a display standard
Key rule: 5G means high speed, massive connections and low latency; LTE is 4G; an MVNO rents capacity on such networks instead of running its own.
