2. Hardware Interface
2.1 Antenna Connections
Air11 has 4 RF Ports ( ANT1, ANT2,ANT3,ANT4) thru MMCX Connector. The maximum RF Power that can be
supplied to 50 ohm load at each port is 30dBm.
RF port can be used one at a time, default value is ANT#0.
Please refer to Command document for selecting the antenna port.
2.2 Antenna Requirements
Air11 is affected by the characteristics of the antenna. When the impedance is 50 ohm and the reflection
loss is -20 dB or less in the frequency band of the applied antenna, it has good characteristics.
When RF power is output while the antenna port is open, the RF module may be damaged.
2.3 Digital/ Power Interfaces
There are power, Serial communication signal and power on/ off signal in Digital connector.
These signals are provided by Yeonho 05002HR-H16J05 and 05002HR-H30J05 on the top of the module.

3. Environmental Specification
Air11 can be connected to the Host in two ways. The 16-pin zip connector can be used by connecting to the
host using the UART interface. And if you use a 30-pin zip connector, you can implement the desired terminal
with only Air11.
It is recommended that fixing the module to the main board in any of connection ways. Air11 generates a lot
of heat when it is operating a Max power (30dBm), it can alleviate temperature rise during operation of the
module by diffusing the heat of the module to the main board.
In addition, when the module is mounted on the main board, the PSR is opened in the module area so that
the main board and the ground of the module can sufficiently contact each other.
Shield is recommended because harmonics generated by the Host Processor may be emitted and introduced
into the antenna of Air11, which may cause performance degradation.

FCC Operation Guide
FCC Information
This device complies with Part 15 of the FCC Results. Operation is subject to the following two conditions:
(1) This Device may not cause harmful interface, and
(2)This Device must accept any interference received, including interference that may cause undesired
operation.
Note : This equipment has been tested and found to comply with the limits for CLASS B digital
device, pursuant to Part 15 FCC Rules. These limits are designed to provide reasonable protection
against harmful interference when the equipment is operated in a commercial environment. This
equipment generates, uses and can radiate radio frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular installation.
If this equipment does cause harmful interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is encouraged to try correct the
interference by one or more of the following measures ;
1.1. Reorient or relocate the receiving antenna.
1.2. Increase the separation between the equipment and receiver.
1.3. Connect the equipment into an outlet on a circuit different from that to
which receiver is connected.
1.4. Consult the dealer or experienced radio/TV technician for help.
This device complies with part 15 of the FCC Rules.
Operation is subject to the following two conditions:
(1) This device may not cause harmful interference, and
(2) This device must accept any interference received, including
interference that may cause undesired operation

WARNING
Changes or modifications not expressly approved by the manufacturer could void the user’s
authority to operate the equipment.
CAUTION : Exposure to Radio Frequency Radiation.
To comply with FCC’s RF exposure limits for general population / uncontrolled exposure, the
antenna(s) used for this transmitter must be installed to provide a separation distance of at
least 20cm from all persons and must not be co-located or operating in conjunction with any
other antenna or transmitter.
Federal Communication Commission Interference Statement
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1)
This device may not cause harmful interference, and (2) this device must accept any interference received,
