Which of the following statements does not apply to mmWave radio propagation ?
Correct Answer: C
The correct answer is C . At mmWave / FR2 frequencies , radio propagation is more challenging than in low-band or mid-band spectrum. Diffraction becomes weaker, blockage is more severe, foliage attenuation is high, and building penetration loss is significant. This is why mmWave networks usually require dense site grids, line-of-sight or near-line-of-sight paths, and strong beamforming. Industry mmWave references consistently describe high path loss, high penetration loss, and the need for directional antenna systems to compensate for these losses. Option C does not apply because water absorption and atmospheric absorption generally become more relevant at higher frequencies, not lower. Rain, humidity, and oxygen/water-vapor absorption are important considerations for mmWave link budgets. So the statement that does not apply to mmWave propagation is: Low water absorption at high frequencies.
Evaluate the impact of extended FR2 cell range on power consumption.
Correct Answer: C
The correct answer is C . In FR2/mmWave , uplink coverage is often the limiting factor because UE transmit power is much lower than gNodeB transmit power, and mmWave propagation suffers from high path loss and blockage. Ericsson's mmWave coverage discussion also notes that high-band coverage is limited by uplink signal quality and high- band propagation characteristics. When the FR2 cell range is extended, UEs farther from the serving cell must transmit uplink signals over a more difficult radio path. This usually requires higher UE transmit power, more robust MCS, more repetitions or retransmissions, and potentially longer uplink activity. As a result, UE battery consumption can increase. Therefore, extended FR2 range generally: Increases power consumption because UEs need more energy to transmit uplink signals.
Evaluate the impact of using MantaRay SON's centralized PCI optimization module compared to distributed SON implementations.
Correct Answer: C
The correct answer is C . A centralized SON approach has broader network-level visibility than a purely distributed implementation. For PCI optimization , this is important because PCI conflicts, PCI confusion, and neighbor-related PCI issues are not always local to one cell. They may involve several neighboring cells, multiple layers, and sometimes multiple vendors. Nokia positions MantaRay SON as a centralized, AI-powered network optimization and automation platform for improving RAN quality, efficiency, and customer experience. Nokia also describes MantaRay SON as supporting multi-supplier/non-real-time RIC functionality in the MantaRay SMO framework. So compared with distributed SON, centralized PCI optimization can better analyze wider-area PCI relationships and resolve PCI problems across multi-vendor or multi-layer networks. Therefore, the correct statement is: Centralized PCI optimization can identify and resolve PCI issues across multi-vendor networks.
Which of these is a software solution targeted to provide NPO projects access to rich datasets, modern data analysis and visualization tools, with a high level of automation capability?
Correct Answer: D
The correct answer is D . NPAS is the correct software solution in this context. A public technical source describes NPAS as providing access to rich datasets and modern data analysis and visualization tools , which matches the wording of the question closely. In Nokia/NPO project context, this type of platform is used to support network planning and optimization activities by enabling data ingestion, analysis, visualization, and automation. This helps engineers work with large RAN datasets more efficiently during optimization, modernization, and performance-improvement projects. The other options are not the best match: GeoSynthesis is more associated with geospatial/planning-style use cases. MantaRay SON is related to SON automation and optimization functions. LTEPAT is more LTE-focused and does not match the described broad analytics platform role. Therefore, the correct answer is: NPAS.
