The Series 9900 Wireless Intercom System is the perfect solution for wireless intercom/radio communications in demanding environments and applications requiring rugged, secure and reliable communications in and around high-noise areas; ideal for push-back operations, wing-walkers, marshalling agents, maintenance mechanics or de-icing operations.

The U9920-GPB Push-Back Gateway is designed specifically for seamless integration with aircraft interphone systems. It acts as a relay for all intercom audio between multiple Wireless Belt Station/Headset users and the interphone systems.

A single Gateway can accommodate up to four (4) connected wireless users at a time with hands-free, full-duplex intercom between a single work group, and Push-To-Talk (PTT) capability for communicating directly with the flight deck.

The U9920-GPB is powered by a Li-Polymer rechargeable battery, capable of 24 hrs. of continual usage between charges, and removable from its water-tight compartment within the RF shielded, marine-grade enclosure.
