Hutchison-owned Three has chosen Huawei as its primary technology partner for its upcoming 5G rollout, diverging from the vendors it used for earlier generations.
For 3G, Three used Nokia equipment, while Samsung supplied its 4G infrastructure. The operator opted to change suppliers again for 5G after concluding Huawei’s solutions offered the most compelling combination of performance and capability.
Many network operators prefer to retain a single vendor across generations to simplify upgrades and control costs. Ericsson, for example, has argued that a strong 4G business naturally positions a vendor well for 5G transitions.
Industry analysts have often rated Huawei ahead of competitors by as much as a year in some areas. The company is particularly noted for its expertise in Massive MIMO antenna systems, which can deliver substantial improvements in spectral efficiency and capacity—key advantages for dense 5G deployments.
Despite its technological strengths, Huawei remains the subject of sustained scrutiny over national security concerns related to its role in critical communications infrastructure. Governments and security agencies in countries including the United States and Australia have publicly opposed Huawei participation in core 5G networks.
Concerns are heightened by the broader range of sensitive use cases 5G is expected to enable—such as connected smart city systems, autonomous vehicles, and remote medical procedures—which could increase the potential impact of any security vulnerabilities or hidden access.
Some of these worries stem from the founder Ren Zhengfei’s past military links and from perceptions about the Chinese state’s influence over domestic companies. Huawei has consistently rejected assertions that it is controlled by the Chinese government.
In the UK, the Huawei Cyber Security Evaluation Centre (HCSEC) was established in 2010 to examine Huawei equipment used in the country’s critical networks. For many years the HCSEC reported only minor issues, but recently it identified “new risks” related to Huawei’s engineering processes. In that update the centre stated, for the first time, that it could only offer “limited assurance” that risks to the UK’s critical networks had been fully mitigated.
Huawei responded to the HCSEC findings by welcoming the scrutiny and acknowledging areas for improvement. A company spokesperson said the report demonstrated the HCSEC’s effectiveness and affirmed Huawei’s commitment to addressing the issues identified. The statement emphasized that cybersecurity is a top priority and that Huawei will continue to refine its engineering practices and risk management systems.
Following the HCSEC report, several UK operators publicly reassessed their relationships with Huawei. O2’s CEO Mark Evans commented that his company is less reliant on Huawei than some competitors, including BT and Vodafone, signaling varying degrees of vendor diversification across the market.
Three, meanwhile, has downplayed the security concerns in relation to its own 5G deployment, noting that many of the issues highlighted concern older equipment and are not directly applicable to the new systems it plans to deploy.
