Teledyne’s AWLUg4 enables high speed, wired and wireless network connectivity on and off your airplane.

Teledyne Controls' fourth generation Aircraft Wireless LAN Unit (AWLUg4) provides operators with a compact, lightweight and cost-effective LAN connectivity solution both onboard the aircraft, and between the aircraft and the corporate network. This integrated system delivers in one single unit the entire infrastructure required for secure wired and wireless onboard Local Area Networks and ARINC 429 devices.

The AWLUg4 is a scalable multi-function unit whose basic functionality is that of an Ethernet switch. It offers additional options that can be added as needed, such as:

ARINC 429 interconnectivity,
802.11 for Terminal Wireless LAN Unit (TWLU) functionality,
and/or 802.11 for Cabin Wireless LAN (CWLU) functionality.

The AWLU utilizes a set of protocols that allow data to be passed from equipment on the ground to equipment in the air, and vice versa, whenever the network is available. The network can be used for such things as routing non-essential ACARS messages to the ground and uploading FMS navigation databases for subsequent loading into a Flight Management Computer. It could also be used to access navigation information from ARINC 429-equipped navigations systems.

As a wireless LAN unit, not only does the AWLUg4 eliminate a large portion of the installation cost of wiring the aircraft for Ethernet, but it also allows flexible wireless high-speed access to the airborne LAN from anywhere on the aircraft. With the 802.11 capability added, the AWLUg4 also provides the capability to move large amounts of digital data on and off the aircraft.
