The company has now been contracted to perform the next phase of the upgrade, which will cover the New England area in the north of the state.
The iPasolink outdoor units are designed to cope with harsh environmental conditions, while their small size reduces tower load and avoids having to strengthen existing towers.
"The new iPasolink platform is underpinning our critical radio communications network, essential to the protection of NSW's seven million people. Not only is it robust in all conditions but its light weight also helps us reduce operational costs," said NSW Police Commander of wireless technology, David Brogden.
NEC Australia radio solutions business manager Krisztian Som said "This contract is another example of NEC's expertise in designing and delivering innovative solutions for Australia's emergency and public safety agencies."
