Extend the Reach of your Network with Global Cellular and WiFi Connectivity

Teledyne Controls' AirLAN™ system is a compact, lightweight and cost-effective networking solution that provides high performance off-board wireless connectivity for Electronic Flight Bag (EFB) solutions, whether standalone or integrated with the Onboard Network System (ONS). The AirLAN system provides 3G/4G cellular connectivity as well as a WiFi option.

Standard Cellular Connectivity
The AirLAN solution includes two HSPA+ modules with downlink speeds (toward the aircraft) up to 21 Mbps, and uplink speeds (away from the aircraft) up to 5.76 Mbps. It also provides fallback capability to HSPA, EDGE and GPRS. The AirLAN solution offers truly global connectivity, operating both in the 3G and GPRS/EDGE frequency bands. Additionally, radio module upgrades to 4G technologies, such as LTE and WiMAX, can be enabled. The cellular antenna(s) are attached to the unit, which eliminates the need for fuselage mounted antennas. The inclusion of two radios and SIMs improves availability through redundancy, and enables roaming charges to be minimized, or even eliminated. The AirLAN system leverages Teledyne's decade of experience with cellular connectivity, sharing the same technology as the Wireless GroundLink® system, a proven solution in commercial service at many airlines worldwide, and certified on numerous aircraft types.

Optional WiFi Connectivity
Also available with a WiFi option, the AirLAN system provides an ARINC 822 compliant IEEE 802.11 a/b/g/n radio capable of operating in both the 2.4 GHz and 5 GHz frequency bands. This WiFi option is compliant with all the latest relevant IEEE and ARINC standards. For WiFi connectivity, a fuselage mounted antenna is highly recommended.

System Integrity and Reliability
The AirLAN device is not repackaged COTS equipment, but purpose built for avionics use. It features the same hardware platform as the one used in Teledyne's Network Extension Device (NED) and Network File Server (NFS), thus sharing the same environmental characteristics and obsolescence management required for the components of the ONS. This makes it a logical choice when it comes to extending the ONS onboard network to off-board wireless LANs and WANs.

System Integration and Management
The AirLAN solution is a versatile system that can be connected either directly to the EFBs via SNMP or to the ONS via SOAP. It is also data loadable over Ethernet via ARINC 615A.
