Persistent Systems, LLC added Full Duplex Audio capability to its MPU5 mobile ad hoc network radio. With this new Full Duplex Audio capability, MPU5 users can now speak freely to each other, as if on intercom system, without having to push-to-talk each time they want to communicate. The Full Duplex Audio is multicast across the MANET enabling users to communicate continuously even in complex multi-hop topologies.
To activate the Full Duplex Audio capability, MPU5 users need only double-tap both buttons on Persistent’s Dual Push-to-Talk (PTT), and they are good to go until the capability is similarly turned off. While Full Duplex is enabled, users can still Push-to-Talk on the Dual-PTT to communicate on other talk groups. The Full Duplex capability works alongside the traditional push-to-talk functionality (not in place of it).
The Full Duplex Audio capability works best with stereo headsets from TEA (Television Equipment Associates, Inc.), which has collaborated with Persistent in developing a fully supported product for MPU5 users.
The Full Duplex functionality is available as a Technology Preview in Persistent’s 19.4 firmware which is available to all MPU5 customers.
