Passengers can use a tablet to hail the autonomous vehicle, which then arrives for pick-up and drives around a programmed seven-minute loop at a maximum speed of 7km/h, though it is capable of 25km/h. An in-vehicle dashboard provides information on how and what the car is monitoring in real-time via LIDAR.
At the same time, Ohmio has been testing autonomous shuttles at Christchurch Airport -- with an upgraded model of the vehicle ensuring it integrates with Spark's 5G connectivity -- and is planning to launch more trials in university campuses, airports, hospitals, and retirement villages across New Zealand.
Ohmio is also planning to apply for on-road certification to test its vehicles on public streets.
"This test with Spark is only the second of its type in the world," Ohmio head of Research and Development Dr Mahmood Hikmet said.
"A 5G network can be up to 100 times faster than 4G, which unlocks the true potential for autonomous driving, as messages need to be transmitted and decisions made in real-time. A significant drop in latency ... will give cars human-like reflexes and opens up multiple possibilities for connected infrastructure and a smart city ecosystem."
Spark's 5G trial network hit a snag when New Zealand's Government Communications Security Bureau (GCSB) in November handed down a draft decision saying the carrier could not use Chinese networking vendor Huawei's technology for deployment.
The final decision has yet to be made, with GCSB Director-General Andrew Hampton at the time saying the "ongoing regulatory process" falls under the nation's Telecommunications Interception Capability and Security Act (TICSA).
"I can confirm the GCSB, under its TICSA responsibilities, has recently undertaken an assessment of a notification from Spark. I have informed Spark that a significant network security risk was identified," Hampton said.
Spark said it had notified the GCSB of its intention to use Huawei equipment in its 5G radio access network (RAN).
"The Director-General has informed Spark today that he considers Spark's proposal to use Huawei 5G equipment in Spark's planned 5G RAN would, if implemented, raise significant national security risks," Spark said in November.
"This means Spark cannot implement or give effect to its proposal to use Huawei RAN equipment in its planned 5G network."
At MWC Americas 2018, TechRepublic spoke with Glenn Lurie, CEO, Synchronoss Technologies about how 5G networks will enable autonomous vehicles to communicate with each other and become four-wheeled clouds.
