How Ozitel Works
Two-Way radios haven’t changed, right? Think again… With the new technology, Push-To-Talk, you can break through the boundaries of traditional Two-Way radio.
What is Ozitel?
Ozitel is a 100% Australian-owned Push-To-Talk (PTT) platform designed for wide-area communications without the need for traditional radio infrastructure. By utilising Australia’s existing 4G/5G mobile networks, Ozitel allows teams of any size to communicate instantly — from city centres to remote work sites.
Whether you’re on a mobile phone, rugged device, or two-way radio – if you have mobile data or WiFi, Ozitel keeps your team connected. In locations without coverage, Ozitel-compatible devices can switch to 2-way radio functionality.
