Former EE Boss Mourns UK Passing of Huawei and 5G Failures

Why It Matters

The forced exit of Huawei reshapes the UK telecom supply chain, heightening reliance on Western vendors and influencing security, cost and innovation dynamics across the sector.

Key Takeaways

• Huawei once powered two‑thirds of EE’s network, now nearly gone
• UK must fully strip Huawei from 5G by end of 2025
• Ericsson and Nokia now supply all UK 5G equipment
• Early 5G rollout delivered weak indoor coverage and missed latency promises
• ARPU fell from £34.60 ($46) in 2012 to £16.40 ($22) in 2025

Pulse Analysis

The United Kingdom’s decision to purge Huawei from its 5G infrastructure reflects a broader geopolitical shift that began with US‑led sanctions and culminated in domestic security legislation. While the ban aims to mitigate espionage risks, it also forces operators like BT to replace legacy gear with costly Ericsson and Nokia solutions, accelerating capital expenditures. This transition highlights the tension between national security imperatives and the financial pressures on telcos already grappling with thin margins.

Technically, Huawei’s equipment has often outperformed Western rivals in power efficiency and form factor, especially its gallium‑nitride‑based radios that consume less energy per bit. However, the early 5G rollout fell short of consumer‑facing promises—indoor coverage remained spotty and latency targets were missed—dampening enthusiasm and contributing to a steep decline in average revenue per user. The ARPU drop from roughly $46 in 2012 to $22 in 2025 illustrates that higher‑speed networks alone do not drive spending without compelling services.

Looking ahead, the UK’s reliance on Ericsson and Nokia consolidates market power among a few suppliers, potentially limiting competition and innovation. At the same time, regulators face pressure to harmonise spectrum allocation and reduce operator fragmentation, issues Swantee flagged as hindering Europe’s rollout speed. As telcos seek new revenue streams—private‑network services, edge computing, and IoT—their ability to balance security, cost, and technology leadership will define the next phase of the UK’s mobile ecosystem.
