General This document covers the system description and installation for the Terminal Wireless LAN Unit (TWLU), Crew Wireless LAN Unit (CWLU), and the derived Wireless LAN Unit (WLU). The WLU is a Honeywell developed common hardware platform that can be configured to provide either Terminal Wireless LAN Unit (TWLU) or Crew Wireless LAN Unit (CWLU) functions. Figure 6-1 shows an exploded view of the WLU. Figure 6-1 Wireless LAN Unit There will be three CWLUs covering the cabin/flight deck, two CWLUs covering eebays/baggage areas, and one CWLU for external coverage. A single TWLU will provide a connection between the aircraft network and airport network at an airport terminal. CWLU and TWLU communications are based on the IEEE 802.11 wireless standard. It is intended that aircraft shall be able to connect through TWLU systems and then access their airline networks, as they move to different airports. Passenger devices are not permitted to send or receive data directly through the WLU. The WLU provides NAT routing between an Ethernet based aircraft network and a ground-based network through the wireless interface. The Wi-Fi wireless interface along with separate internally and externally mounted aircraft antenna will act as 802.11 client stations and operate in IEEE 802.11b/g modes. The Ethernet will support a 10/100 Mbps interface (IEEE 802.3) and be capable of supporting up to 4 Ethernet clients. The Wi-Fi primary mode of operation will be IEEE 802.11 infrastructure mode but may also participate in ad-hoc sessions. The WLU was designed with the intent to support future changes in security, which were under development within the wireless network industry when this document was written. The WLU application software is field upgradeable via its Ethernet port. A diagram of the TWLU and CWLU typical communication links is shown in Figure 6-2.

TWLU Functional Description The wireless connection established between the airplane and airport networks is referred to as Gatelink. Gatelink is a ground based WLAN network designed to connect aircraft. Gatelink networks can connect to airline networks, etc. Gatelink is intended to be implemented at airports but may also be applied at aircraft support facilities. Gatelink is described in the AEEC standard, ARINC 763, Aircraft Network Server System. It is based on the IEEE 802.11 wireless standard. It is intended that aircraft shall be able to connect to Gatelink systems and then access their airline networks, as they move to different airports. Gatelink may be implemented by an airport authority, which then shares the resource across all airlines. 7.1.2. CWLU Functional Description The CWLU provides wireless connectivity to crew and maintenance applications within the aircraft. Enforcement of which wireless users can use the CWLU system is performed by a combination of CWLUs and an aircraft On-board Authentication Server that supports the RADIUS protocol with WPA2 extensions. The CWLU is configured and radio enabled after landing or after reaching altitude threshold. The CWLU begins sending IEEE802.11 beacons. Wireless computers detect CWLU beacons and initiate association. CAGE CODE: HIF-1472R6(1) 97896 SCALE: NONE SIZE: A DWG NO. REV: SHEET 9 7.2.

FCC CFR 47 CFR 15.247 System Operation There are no user controls located on the WLU. The TWLU and CWLUs are managed, monitored, configured, and controlled by the WLAN Manager function. WLAN Manager is hosted on the CIS-MS Server. These wireless devices need to be configured dynamically so that they comply with country regulations when the aircraft lands. CAGE CODE: HIF-1472R6(1) 97896 SCALE: NONE SIZE: A DWG NO. REV: SHEET 11 Boeing decides what the correct country settings need to be and agree on the parameters and rules Honeywell uses to decide when to change the configurations. Airport identifiers shall map to configuration settings. Airlines need be able to configure parameters that vary based on where the aircraft is used and security. Examples of this include which airports provide Gatelink to the airline, what the associated ESSID are, TWLU and CWLU digital certificate keys. An overview of the two modes of operation is given below. 7.3.1. TWLU Operation The TWLU radio is enabled when the aircraft is on the ground, at approved airports, that the airline has Gatelink agreements with. It is disabled while the aircraft is in the air. The WLAN Manager monitors, configures, and controls the TWLU. After an aircraft lands, the WLAN Manager: detects aircraft is on ground (Aircraft parameter:: in air) determines which airport the aircraft is at (Aircraft parameter: airport identifier parameter) looks up the airport settings in the CISS AMI configures the TWLU at that airport with: o ESSID, RF power/mode, encryption setting, etc. o Uploads necessary Gatelink public key certificate trust anchor verifies TWLU configuration and enables RF radio An aircraft lands at a Gatelink enabled airport that it is registered to use. The TWLU is configured and radio enabled after landing. The TWLU begins sending IEEE802.11 probes. Gatelink APs send beacons and probe responses. The TWLU associates with a Gatelink Access Point. IEEE802.11i/WPA2 authentication and encryption is performed. Upon successful completion, the TWLU obtains an IP address from Gatelink and begins its operation as a NAT/PAT network router. The wireless connection can roam to other Gatelink Access Points as the aircraft moves. 7.3.2. CWLU Operation The CWLAN is available during ground and cruising flight phases. CWLUs are configured to their default country settings, for operation in the air. They are disabled when the aircraft is below an altitude threshold level (e.g. 10,000 AGL). After aircraft landing, the WLAN Manager: detects aircraft is on ground (CDN parameter In Air) determines which airport the aircraft is at (CDN avionics airport identifier parameter) looks up the airport in its tables configures the CWLU: o RF power/mode, encryption setting, etc. verifies CWLU configuration enables RF radio After aircraft take off, the WLAN Manager: detects aircraft is in the air (CDN parameter In Air) disables the CWLU RF outputs configures the CWLUs to default settings: o RF power/mode, encryption setting, etc. verifies CWLU configuration after reaching altitude threshold (CDN altitude parameter, 10,000 AGL), enables CWLU RF radios CAGE CODE: HIF-1472R6(1) 97896 SCALE: NONE SIZE: A DWG NO. REV: SHEET 12 An aircraft lands at an airport in a country that allows CWLAN operation. The CWLU is configured and radio enabled after landing. The CWLU begins sending IEEE802.11 beacons. Wireless computers detect CWLU beacons and initiate association. IEEE802.11i/WPA2 authentication and encryption is performed. Upon successful completion, the CWLU permits valid Wireless computers CWLAN access. 8. SYSTEM INTERFACES 8.1. High Level Functionality 8.1.1.

Figure 9-1 shows the WLU mounting hole dimensions, as well as the mechanical outline. The depth or protrusion of the J1 and J2 connectors are 0.78 inches maximum. The WLU is a bolt-down low profile package with the footprint defined in ARINC 763. CAGE CODE: HIF-1472R6(1) 97896 SCALE: NONE SIZE: A DWG NO. REV: SHEET 16 Figure 9-1 Mechanical Outline of WLU 9.2. Equipment and Materials The TWLU should be mounted with six screws and washers. The necessary screws and washers will be certified by Boeing to be flight worthy. 10. ELECTRICAL INSTALLATION 10.1. General These sections give electrical installation procedures, power distribution, and interconnect information for the WLU. Procedures for proper shield, power, and signal grounding are also provided in this section. In addition, procedures for the various buses are included. 10.2. Power requirements The information necessary to provide the electrical interconnects is contained in the following paragraphs. CAGE CODE: HIF-1472R6(1) 97896 SCALE: NONE SIZE: A DWG NO. REV: SHEET 17 10.2.1. DC Power The aircraft DC power supply must be 28 V DC (nominal). The normal minimum and maximum voltages permitted are 22 and 29.5 V DC respectively. The maximum current drawn by WLU is 0.32 +/- 0.03 Amps at 28 VDC, equivalent to a maximum power consumption of 10 watts. 10.2.2. Ground Requirements Proper grounding is a key factor in ensuring proper system operation under normal conditions, high intensity radiated electromagnetic frequencies (HIRF), and lightning environments. You must obey this section to satisfy these requirements. NOTE: HIRF and lightning requirements dictate that the shielded wires meet the requirements of Shielded Grounds. Installation of this system into aircraft manufactured prior to the FAA requirements adheres to these practices whenever feasible. All electrical conductors, terminals posts and component parts that are not at ground potential shall be insulated or otherwise protected to prevent hardware from creating a short circuit or a spark ignition source. The WLU is designed to be grounded by the chassis to the ground structure directly. The WLU allows a total DC voltage drop of less than or equal to 0.7VDC for the 28V DC return path to the RPDU. 11. ANTENNA INSTALLATION 11.1. General WARNING: This equipment complies with FCC radiation exposure limits set forth for uncontrolled environment. This equipment must be installed and operated with a minimum distance of 20 cm between the radiator/antenna and your body. This section provides general guidelines for installing Wi-Fi antennas with the WLU. Due to the wide variation of wireless regulations from country to country, the exact model antennas to be used with the WLU are left to the customer/installer and country regulations. Honeywell has certified the Sensor Systems antennas listed in Table 7-1. The maximum power output of the TWLU before cable loss is equal to 18 dBm. The RF cable used between the TWLU and antenna is should have insertion of approximately 3 dB. The maximum gain of the Wi-Fi Antenna listed in Table 7-1 is equal to 5 dBi. Figure 11-1 shows an overall diagram representing the gain and loss of the system. The maximum Effective Radiated Power (ERP) at the antenna should be 20 dBm if installing an antenna other than the Wi-Fi antennas listed in Table 7-1.

General This section describes the built-in test equipment (BITE) function for the WLU. System BITE contributes to a number of maintenance functions: Detection of internal and external faults Reporting failure status in the air and on the ground Ground test capability for isolating faults, performance verification, and system level testing. 12.2. Fault Detection The WLU detects faults using continuous monitors in all system modes where the fault is detectable. The WLU continuously monitors for internal hardware, software and interface faults and sends fault messages via WLAN Manager, when they occur. The WLU automatically detects each fault condition that causes either: One or more digital output signals to be identified as failed or invalid Loss or significant degradation in other outputs to other systems. A fault is defined and set for each of the test components. Fault Monitor Data may include up to 600 characters of free text to add details relevant to failures. The continually monitored tests cover the following components: Power Supply (fault if power supply output is outside accepted range) Processor (fault if processor error or overheat condition occurs) Memory (volatile and non-volatile, fault if memory error occurs) Software execution (fault is software error occurs) Configuration (fault if configuration is corrupted) CAGE CODE: HIF-1472R6(1) 97896 SCALE: NONE SIZE: A DWG NO. REV: SHEET 19 Radio Functional (fault if Radio doesn’t respond to processor) Ethernet interface (fault if interface is down) Discrete interfaces (fault is interfaces are in invalid configuration) WLAN Manager Authentication State (fault if Manager authentication fails) WLAN Authentication State (fault if WLAN authentication fails) WLAN Encryption State (fault if encryption fails) WLAN Connection State (fault if connection fails) Gatelink Connection State (fault if connection fails when Gatelink is available) Router State(fault if router function fails in TWLU when Gatelink is connected) DHCP State (fault if DHCP client in TWLU does not get IP address from Gatelink Bridge State (fault if bridge function in CWLU fails) 13. DATA LOADING 13.1. General The WLU applications are data loaded on to the WLU directly by a ARINC 615A data loader. The WLAN Manager must first notify the TWLU that the aircraft is in Maintenance Mode, before an aircraft data load is accepted. Data loading is performed on the aircraft by the CIS Server Data Loader application, while in maintenance mode. It can also be performed off the aircraft with a Data Loader.
