EQUIPMENT DESCRIPTION
The Cabin Access Point (CAP) (Figure 1-1) is a wireless communication device designed for use in
airborne environments. The CAP utilizes Direct Sequence Spread Spectrum (DSSS) radio
technology in the 2.4-GHz Industrial, Scientific and Medical (ISM) radio frequency spectrum to
communicate with IEEE 802.11b compliant wireless devices. The CAP utilizes Orthogonal
Frequency Division Multiplexing (OFDM) radio technology in the 2.4-GHz ISM radio frequency
spectrum to communicate with IEEE 802.11g compliant wireless devices and in the 5-GHz ISM
frequency spectrum to communicate with IEEE 802.11a compliant wireless devices. The CAP
provides a bridge between the aircraft IEEE 802.3 compliant wired Ethernet LAN and wireless
devices. Two aircraft level discrete inputs are provided for remote on/off control and RF
enable/disable. Two discrete outputs provide operational status. Operation of the CAP is controlled
by operating software. The CAP can be configured with CAP operating software to configure the
CAP as a cabin wireless LAN unit (CWLU) to create a wireless local area network (WLAN) aboard
the aircraft, or with wireless access bridge (WAB) operating software to configure the CAP as a
terminal wireless LAN unit (TWLU) to establish a wireless bridge between the aircraft network and
a ground-based network. The part number for the software installed in your CAP is indicated on the
software label located on the top of the CAP unit.

BUILDING A WIRELESS LOCAL AREA NETWORK (WLAN)
Configured as a CWLU, the CAP enables you to create a WLAN to link all your computers so that
they can share data and resources.
The CAP contains two radio frequency (RF) transmitter/receivers (tranceivers). One tranceiver uses
radio waves in the 2.4 GHz band to communicate with IEEE 802.11b and IEEE 802.11g compliant
client stations. The second transceiver uses radio waves in the 5 GHz band to communicate with
IEEE 802.11a compliant client stations. Radio waves cannot penetrate metal, instead they are
reflected. This means that the CAP is able to transmit through wood or plaster walls, and closed
windows. However, the metal skin of the aircraft or metal partitions may block transmissions, or
reduce signal quality by creating reflections. To serve users separated by metal partitions will
require a separate CAP unit in each area.
The CAP provides IEEE 802.11b and IEEE 802.11g wireless network coverage in a radius of up to
100 meters (300 feet) and IEEE 802.11a wireless network coverage in a radius of 30 meters
(100 feet), regardless of the orientation of the device. This is called a wireless cell.
To maximize coverage of the cell, the CAP is best installed in an open area with as few obstructions
as possible. Try to choose a location that is central to the area being served.
The following paragraphs provide an overview of the different types of connections you can make
using the CAP.

Instant Infrastructure
The CAP features an integrated two-port 100 Mbps Ethernet switch allowing you to quickly create a
complete networking infrastructure. Connect stand alone computers or link to an Ethernet hub to
interconnect your wireless network with a traditional wired local area network (LAN). (See
Figure 1-4.) This enables all users to share data and resources.
Unlike a hub which shares bandwidth between all connected stations, the CAP’s switch enables each
connected station to use the full 100 Mbps. Both ports on the CAP are auto-sensing, enabling direct
connection to a hub without a crossover cable.

Building A Multi-Cell Wireless Network
As shown in Figure 1-5, several CAP units can be installed to provide multiple wireless cells for
coverage of large locations. Client computers are able to move between cells (called roaming),
without losing contact with the network. This is possible because the wireless network adapters in
the client computers automatically switch to the best available signal.

BUILDING A WIRELESS BRIDGE
Configured as a TWLU, the CAP provides a wireless link between the LAN aboard the aircraft and a
ground-based LAN deployed in an airport terminal, hanger, fixed-based operation (FBO) facility, or
flight operations facility. (See Figure 1-6.) The CAP has a range of 100 meters (300 feet) using the
IEEE 802.11b or IEEE 802.11g wireless network interface.

RF (Antenna) Output
WARNING
The CAP antenna radiates radio frequency
(RF) power. To avoid exceeding federal
communications commission (FCC) radio
frequency exposure limits, human proximity
to the antenna shall be no less than eight
inches (20 centimeters) while RF is enabled.
The CAP is designed to be used with two indoor antennas, Miltope part number 901167-1, when
configured as a CWLU (using CAP operating software) or one outdoor antenna, Miltope part number
901058-1, when configured as a TWLU (using WAB operating software). The two indoor antennas
connect to the two RF output connectors shown in Figure 3-6. Connector J2 is the RF output for
radio 2 and connector J3 is the RF output for radio 1. The outdoor antenna connects to RF output
connector J3 shown in Figure 3-6. Table 3-2 provides the pin assignments for the RF output
connectors.
To comply with Federal Communications Commission (FCC) requirements, attenuation is required
between the CAP and the antenna for IEEE 802.11b and/or IEEE 802.11g operation at maximum
transmit power. This attenuation is typically accomplished by connecting a minimum of six feet of
RG-58 coaxial cable (or alternate coaxial cable with equivalent attenuation characteristics) between
the CAP and the antenna. If no extension cable is connected between the CAP and the antenna, the
applicable radio transmit power must be set to a maximum value of 15 dBm. Refer to the applicable
operating software operator’s manual for instructions for setting radio transmit power.

Discrete Inputs
Two ground/open type discrete inputs as defined by ARINC 763-2 are provided via I/O connector J1
to enable external control of CAP operation. An external controller or switch panel can be used to
power up the CAP and enable wireless operation. Connecting a ground to on/off control (pin 14)
causes the CAP to power up. When the ground is disconnected, the CAP will power down.
Connecting a ground to RF enable/disable (pin 15) will enable wireless operation. When the ground
is disconnected, wireless operation is disabled. The wired LAN remains operational when wireless
operation is disabled.

Low Throughput
Symptoms
Client computers are experiencing delays when transmitting. One or more of following statistics on
the wireless status page are excessively high: Tx multiple retry frames, Tx single retry frames,
Tx deferred transmissions
Causes
•
•
•
•
•
Too many client stations are using the network, or one or more clients is monopolizing the
bandwidth with excessively large transfers.
Signal quality to one or more stations is poor or being subject to interference (interference caused
by cordless phone or microwave oven for example). This can cause excessive retransmissions of
data and collisions. Both create overhead that will slow down overall throughput.
Antenna installation not optimized for adequate coverage area.
One or more CAP units are sharing the same operating frequency. This can cause excessive
retransmissions to occur, especially if the units are close together.
The CAP is sharing the same operating frequency with third-party wireless device nearby. This
can cause excessive retransmissions to occur, especially if the units are close together.

HEALTH INFORMATION
The CAP, like other radio devices, emits radio frequency electromagnetic energy. The level of
energy emitted by the CAP is much less than the electromagnetic energy emitted by other wireless
devices, such as mobile phones.
Because the CAP operates within the guidelines found in radio frequency safety standards and
recommendations, Miltope Corporation believes that the CAP is safe for use by consumers. These
standards and recommendations reflect the consensus of the scientific community and result from
deliberations of panels and committees of scientists who continually review and interpret the
extensive research literature.
