Dutch operator KPN announced it has signed an agreement with Huawei to build the 5G radio network but will only select a western vendor for 5G core.
KPN said it will modernise its mobile network towards 5G, and has adopted a tightened security policy with regard to vendor selection. The company believes that “the mobile core network which from a security point of view is more sensitive”, while the RAN is less so.
As a result, the operator has entered into a preliminary agreement with Huawei to provide the radio access part of the 5G network, but the agreement is adjustable and reversable “to align it with future Dutch government policy.” Meanwhile, the company “plans to select a Western vendor for the construction of the new mobile core network for 5G.”
Jan Kees de Jager, KPN’s CFO, told the media separately that the upgrade will also involve swapping out Huawei equipment from its current core network, according to a report by Reuters. In contrast to what his counterparts in Germany and the UK have claimed, de Jager did not believe switching from Huawei for other vendors would lead to addition cost. Equipment from Nokia, Ericsson and other suppliers would be as affordable as Huawei for the 5G infrastructure, he was reported to tell the media.
“We appreciate KPN’s trust and are honoured by their decision to partner with us for the mobile radio access network modernisation,” said a Huawei spokesperson. “We are committed to support KPN in their ambition to maintain and strengthen their lead in the global telecoms industry.In general, Huawei believes that excluding parties based on geographical origin does not provide a higher level of security. Cyber security can be improved by establishing standards that apply to all parties in the sector. Today, the IT supply chain is highly globalised. Cyber security must therefore be addressed jointly at a global level and suppliers must not be treated differently based on the country of origin.”
KPN is essentially adopting the same policy as the leaked UK government guideline related Huawei’s role in the country’s 5G network: banned from the core but fine to use in the RAN. But precisely because it is adopting the same policy, KPN has to face the same issue raised by Tom Tugenthat MP, chairman of the British parliamentary Foreign Affairs Committee, that it will be very hard to insulate the non-core from the core on 5G network thanks to its virtualisation and software-defined nature.
Additionally, although equipment from different vendors should work together as they all comply with the 3GPP standards, standards do not cover every detail. As Huawei stand staff told Telecoms.com during MWC, there are plenty of discreet innovations vendors can make to optimise the performance of the system if both RAN and core come from the same vendor. So, operators might risk having subprime performance out of the network equipment sourced from different vendors, if not facing downright incompatibility headache.
