NITRO Mobile Coverage AssuranceUse CasesMulti-band and 5G Coverage Analysis• VIAVI Solutions solves the 5G business case

providing a Network Wide, Integrated RAN & CORE, Dashboard.

• In real-time VIAVI provides visibility to the 5G cover• The solution combines RAN and CORE KPIs for

Accessibility, Mobility, Retainability and Integrity information into a single dashboard that summarizes it into easy to understand & actionable information with workflows that allow less skilled users to identify areas of poor quality and to triage to the part of the network, CORE or RAN, that is causing the poor performance. The solution also provides dynamic zoom of coverage, quality and performance from national, region to street level.

• KPIs: Blocks, Drops, RSRP, RSRQ, SINR, Throughput.

• VIAVI Solutions solves the 5G business case providing a Network Wide, Integrated RAN & CORE, Dashboard.

• In real-time VIAVI provides visibility to the national 5G coverage providing fast, prioritised quality analysis and focusing 5G investment.


NITRO Mobile Coverage AssuranceUse CasesMulti-band and 5G 3D Coverage Analysis• VIAVI Solutions solves the 5G business case pr• As the network becomes complex, VIAVI provides

visibility to the vertical position. Beam forming is subject to different levels of propagation, penetration losses and multi-path effects. 5G coverage and capacity is directly affected by topography factors such as buildings, foliage or even temporal blockages such as buses, billboards and others. Near real time view and alarming on individual beams and subscriber level coverage info in 3D is key to assurance 5G coverage and quick reaction to improve specific areas.

• KPIs: Blocks, Drops, RSRP, RSRQ, SINR, Throughput.

• VIAVI Solutions solves the 5G business case providing 3D geolocation intelligence.


NITRO Mobile Coverage AssuranceUse Cases5G IRAT Issues• Near real-time view and alarming on location of

high concentration of IRAT HO (loss of 5G coverage, Time not on 5G)

• Near real time view and alarming location off high IRAT HO failure rates.

• KPIs: Redirection to other technologies, Handover to other technologies, Excessive HO in a certain location, Count of successful HO, Data volume before/after the IRAT HO.


NITRO Mobile Coverage AssuranceUse Cases5G Performance & Quality Verification (eMBB)

• 5G visibility of throughput and data volumes per user and beams as well as control plane and user plane quality of service delivered

• KPIs: Drops, blocks, 5QI, RRC connection success rate, RRC re-establishments by cause, HO success rate


Coverage Assurance

User can quickly zoom from a countrywide 2D coverage view to a regional view and then finally down to a 3D street level view
