ARINC 833 PDF

Purpose and Scope

ARINC Specification 833 describes a system which provides wireless communication channels in the cabin. This system may reduce the installation and integration effort of multiple stand-alone wireless systems. In addition, it specifies the interface between multiple wireless systems to the Universal Wireless Distribution System (UWDS). Compliance with this standard enables common wireless distribution of disparate wireless system signals.

The system includes the following components:

• RF-Combiner unit(s)

• Cabin broadband antenna(e)

ARINC Specification 833 addresses the interfaces to the UWDS, RF-Combiner Unit and the broadband antenna.

The UWDS standard includes the physical interfaces, connectors, space envelopes, equipment mounting, component co-location requirements, antenna characteristics, frequency range, and power requirements. Design guidelines are included as far as they impact the interfaces and installation of cabin equipment on board the aircraft.

The system specified in this document may be designed to support wireless passenger and crew/flight deck applications in the aircraft cabin, flight deck, and cargo area. This specification describes a system that should be designed for maximum functionality and scalability.
