A statement from the company said the trial, at Spark's 5G lab in Auckland, demonstrated the technical implementation of access and core separation.
The trial used a Huawei 5G NR (New Radio on both the C-band and mmWave) and a 4G Radio Access Network, both of which were deployed by using dedicated hardware connected to the Cisco Evolved Packet Core, with each component isolated.
This is the first multi-vendor 5G trial to achieve the benchmark set by Release 15 of the 3GPP standard. Spark has achieved the milestone of the world’s first 5G mmWave call through this network.
“The distinction between core and edge collapses in 5G networks. That means that a potential threat anywhere in the network will be a threat to the whole network,” he was quoted as saying in The Australian.
Huawei New Zealand deputy managing director Andrew Bowater said: “The Auckland live multi-vendor 5G trial emphatically proves it is possible to retain the critical access-core network separation, which enables operators such as Spark to operate in a multi-vendor network environment, and retains the ability of governments to regulate the vendor technology mix while maintaining a competitive market.
“This is the fourth year of Huawei’s strategic partnership with Spark, and we are proud to have brought this multi-vendor 5G trial alive right here in Auckland. The live trial is designed in full accordance with the 3GPP Release 15 industry standards and proves the ability of existing networks to evolve from 4G to 5G smoothly.”
Spark’s technology director Mark Beder said the company was excited to be leading the 5G race in New Zealand.
“For Spark, 5G will drive the next evolution of our business and we are motivated to push the boundaries of this new technology," he said.
"It will deliver significantly faster speeds and more data capacity than previous generations of mobile technology and will support massive connectivity. The possibilities are endless, and we intend to make sure that Spark plays a key role in enabling this 5G journey for all of New Zealand."
