The race is on for telecommunications firms to launch fourth generation mobile broadband network technology to cater for the growing number of data-hungry businesses.
4G networks, also known as Long Term Evolution (LTE) are seen as the future of the mobile phone, offering super fast speeds.
They are already being trialled in the United Kingdom and rolled out in the United States and parts of Australia.
Telecom has announced it will be trialing 4G technology in New Zealand before the end of this year.
But the chief executive of the Telecommunications Users Association (TUANZ) says Telecom has provided little detail about exactly what will be trialled, or when the full service will be available.
Paul Brislen says the spectrum to be used is unknown, whether it will use phones or tablets, where the trail will be or at what price.
