Auria Wireless LTE25 push-to-talk system

LTE25 is a narrowband push-to-talk P25 over LTE solution that provides a missing link in the migration of narrowband to broadband solutions and a key component in hybrid LTE and APCO P25 networks.

It is suitable for first responders such as police and fire departments as it provides robust, secure voice and data services within the LTE network while still bridging APCO P25 digital radio networks and legacy LMR/PMR assets.

The architecture allows the hosting of multiple end-user organisations in a ‘multiagency’ public safety solution. Alternatively, dedicated solution sets can be deployed for specific end users.

Among a number of additional network elements, the main part is a high-availability softswitch, which manages calls and services and supports both the ISSI and CSSI interfaces.

It also includes an Android client application which is said to improve call quality via a native vocoder, eliminate transcoding latency delay and allow end-to-end encryption between P25 and LTE devices. Other features include push-to-talk group calls, priority and emergency call support, location/tracking services and a geographically dispersed disaster recovery node.
