CRITICAL
Nokia Config Drifter cohort — CM parameter drift accelerating
Open

847 Nokia BBU elements in the North cluster are showing progressive CM drift from golden baseline following SW upgrade 6 weeks ago. 23% have non-default srPeriodicity values. NHI has declined an average of 16pts since upgrade. 3 elements have migrated to Persistent Degrader this week.

Affected
847 elements
Config Drifter
Region
North cluster — Cheshire, Lancashire, Cumbria
Team
Network Engineering
Recommended action
Initiate CM audit on all 847 elements. Prioritise srPeriodicity and prachConfigIndex remediation. Cross-reference with Nokia upgrade documentation for known post-upgrade parameter resets.
HIGH
Huawei EoL cohort — HW support expiry in 67 days
Open

214 Huawei BTS units installed 2015–2016 have HW EoL date within 67 days. No support contract extension has been confirmed with Huawei. Current NHI average 44 — Aging Macro archetype. Failure risk increases significantly post-EoL without active support.

Affected
214 elements

Region
Midlands and South West
Team
Network Engineering + Procurement
Recommended action
Escalate to Procurement for support contract decision. If no extension: initiate replacement planning. Priority: highest-traffic sites first.
MEDIUM
38 Ericsson cells approaching utilisation ceiling
In Progress

38 Ericsson eNBs in London South cluster are running at 81–84% DL throughput utilisation. At current week-on-week traffic growth rate (+1.2%), threshold breach is projected within 3–4 weeks.

Affected
38 elements

Capacity Planning
Recommended action
Review capacity plan for London South. Assess carrier aggregation options or small cell densification. Time-sensitive before customer impact.
OPPORTUNITY
Post-Upgrade Settling cohort recovery on track
In Progress

The 1,400 Nokia elements upgraded 2–4 weeks ago are stabilising. NHI has recovered +1pt this week. CM remediation is 92% complete on the affected cohort. At current recovery rate, full migration back to High Performer archetype expected within 3–4 weeks.

Affected
1,400 elements
Post-Upgrade Settling
Region
North cluster (earlier cohort)
Team
Network Engineering
Recommended action
Continue CM remediation. No escalation required.
RESOLVED
Persistent Degrader cohort root cause identified
Resolved

Following field investigation of 12 elements in prolonged NHI decline, root cause identified as antenna feeder corrosion at 9 sites. Physical remediation completed. NHI recovery expected over next 2–3 weeks.

Affected

Recommended action
Expand antenna inspection programme to remaining rural macro sites in similar climate zones.
MEDIUM
Ericsson SW upgrade backlog — 712 elements on n-2 release
New

712 Ericsson eNBs remain on a software release 2 versions behind current. Vendor support for this release ends in Q4 2026. No active performance impact yet — pre-emptive risk flag.

Recommended action
Schedule SW upgrade programme. Coordinate with Ericsson TAC to avoid post-upgrade config drift (lesson from Nokia cohort).
