Which spectrum band is primarily used for 5G mmWave deployments in dense urban US markets due to its extremely high bandwidth but limited range?
Answer: 24–100 GHz (mmWave)
Millimeter wave (mmWave) frequencies between 24 GHz and 100 GHz offer multi-gigabit speeds but have very short propagation distances and limited building penetration.
In the US telecom industry, what does the term 'neutral host' refer to in the context of 5G small cell infrastructure?
Answer: A shared infrastructure provider that hosts multiple operators on a single network build-out
A neutral host is a third-party infrastructure provider that deploys and operates shared network infrastructure (such as small cells in stadiums or transit systems) that multiple carriers can utilize.
What is the significance of 3GPP Release 17 for enterprise telecommunications use cases in the US?
Answer: It added enhancements for NR-Light (RedCap) devices, sidelink communications, and NTN satellite integration
3GPP Release 17 introduced Reduced Capability (RedCap) devices for wearables and IoT, direct device-to-device sidelink communication, and non-terrestrial network (NTN) support for satellite connectivity.
A telecom executive is assessing private 5G network deployment for a US manufacturing client. What is the most critical advantage of a standalone private 5G network over shared public 5G?
Answer: Guaranteed data isolation, deterministic latency, and customized QoS for enterprise applications
Private 5G networks provide dedicated spectrum, guaranteed throughput and latency, and full data sovereignty, making them ideal for mission-critical industrial applications.
Which technology enables telecom networks to dynamically allocate spectrum between uplink and downlink transmission in 5G TDD systems?
Answer: Flexible TDD slot configuration
5G NR's flexible TDD slot configuration allows operators to dynamically adjust the ratio of downlink to uplink slots based on real-time traffic demand, maximizing spectral efficiency.
In a US carrier's roadmap, what is the primary function of a Service Based Architecture (SBA) introduced in 5G core (5GC)?
Answer: To expose network functions as services consumable via APIs using HTTP/2 and JSON
The 5G Core Service Based Architecture exposes network functions (AMF, SMF, UPF, etc.) as microservices communicating via REST APIs over HTTP/2, enabling agile deployment and third-party integration.
