This is the fastest mobile data speed in New Zealand and three times faster than the highest recorded speed on the Spark network.
The new technology enabled at Spark's Hereford Street exchange in Christchurch, has been deployed on a combination of 2300MHz spectrum - only acquired by Spark a few weeks ago - and the existing 2600MHz and 700MHz range.
There are no phones or modems in New Zealand that currently support the full range of 4.5G features, which means the Spark network is now ahead of devices.
4.5G is an evolution of the 4G technology that is already available to 90% of where New Zealanders work, live and play on the Spark network, and until now has not been trialled or commercially available in New Zealand.
Central Christchurch has been chosen as the first location for deployment, but Spark customers can expect more areas to be enabled with 4.5G as compatible devices become available.
Huawei South Pacific President David Wei said "The 4G network we have built with Spark is already one of the world's best. This next generation 4.5G technology allows us to take full advantage of Spark's spectrum investment to achieve incredible speeds and bandwidth."
