Shielding
The module is fully shielded to protect against EMI and must not be removed.
Determining the antenna's location
When deciding where to put the antennas:
‧Antenna location may affect RF performance. Although the module is shielded to prevent
interference in most applications, the placement of the antenna is still very important—if the
host device is insufficiently shielded, high levels of broadband or spurious noise can
degrade the module's performance.
‧Connecting cables between the module and the antenna must have 50 ohm impedance. If
the impedance of the module is mismatched, RF performance is reduced significantly.
‧Antenna cables should be routed, if possible, away from noise sources (switching power
supplies, LCD assemblies, etc.). If the cables are near the noise sources, the noise may be
coupled into the RF cable and into the antenna.
Ground connection
When connecting the module to system ground:
‧Prevent noise leakage by establishing a very good ground connection to the module
through the host connector.
‧Connect to system ground using the two mounting holes at the top of the module.
‧Minimize ground noise leakage into the RF.
Depending on the host board design, noise could potentially be coupled to the module from
the host board. This is mainly an issue for host designs that have signals traveling along
the length of the module, or circuitry operating at both ends of the module interconnects.
Interference from other wireless devices
Wireless devices operating inside the host device can cause interference that affects the
module.
To determine the most suitable locations for antennas on your host device, evaluate each
wireless device's radio system, considering the following:
‧Any harmonics, sub-harmonics, or cross-products of signals generated by wireless
devices that fall in the module's Rx range may cause spurious response, resulting in
decreased Rx performance.
‧The Tx power and corresponding broadband noise of other wireless devices may overload
or increase the noise floor of the module's receiver, resulting in Rx desense.
The severity of this interference depends on the closeness of the other antennas to the
module's antenna. To determine suitable locations for each wireless device's antenna,
thoroughly evaluate your host device's design.
Host-generated RF interference
All electronic computing devices generate RF interference that can negatively affect the
receive sensitivity of the module.?
Proximity of host electronics to the antenna in wireless devices can contribute to decreased
Rx performance. Components that are most likely to cause this include:
‧Microprocessor and memory
‧Display panel and display drivers
‧Switching-mode power supplies
Device-generated RF interference
The module can cause interference with other devices. Wireless devices such as AirPrime
embedded modules transmit in bursts (pulse transients) for set durations (RF burst
frequencies). Hearing aids and speakers convert these burst frequencies into audible
frequencies, resulting in audible noise.
Methods to mitigate decreased Rx performance
It is important to investigate sources of localized interference early in the design cycle. To
reduce the effect of device-generated RF on Rx performance:
‧Put the antenna as far as possible from sources of interference. The drawback is that the
module may be less convenient to use.
‧Shield the host device. The module itself is well shielded to avoid external interference.
However, the antenna cannot be shielded for obvious reasons. In most instances, it is
necessary to employ shielding on the components of the host device (such as the main
processor and parallel bus) that have the highest RF emissions.
‧ Filter out unwanted high-order harmonic energy by using discrete filtering on low
frequency lines.
‧Form shielding layers around high-speed clock traces by using multi-layer PCBs.
‧Route antenna cables away from noise sources.
Notice
Due to the nature of wireless communications, transmission and reception of data can
never be guaranteed. Data may be delayed, corrupted (i.e., have errors) or be totally lost.
Although significant delays or losses of data are rare when wireless devices such as the
WNC modem are used in a normal manner with a well-constructed network, the WNC
modem should not be used in situations where failure to transmit or receive data could
result in damage of any kind to the user or any other party, including but not limited to
personal injury, death, or loss of property. WNC accepts no responsibility for damages of
any kind resulting from delays or errors in data transmitted or received using the WNC
modem, or for failure of the WNC modem to transmit or receive such data.
Safety and Hazards
Do not operate the WNC modem in areas where blasting is in progress, where explosive
atmospheres may be present, near medical equipment, near life support equipment, or any
equipment which may be susceptible to any form of radio interference. In such areas, the
WNC modem MUST BE POWERED OFF. The WNC modem can transmit signals that
could interfere with this equipment.
Do not operate the WNC modem in any aircraft, whether the aircraft is on the ground or in
flight. In aircraft, the WNC modem MUST BE POWERED OFF. When operating, the WNC
modem can transmit signals that could interfere with various onboard systems.
Note: Some airlines may permit the use of cellular phones while the aircraft is on the
ground and the door is open. WNC modems may be used at this time.
The driver or operator of any vehicle should not operate the WNC modem while in control
of a vehicle. Doing so will detract from the driver or operator's control and operation of that
vehicle. In some states and provinces, operating such communications devices while in
control of a vehicle is an offence.
Manual Information for End Users
The OEM integrator has to be aware not to provide information to the end user regarding
how to install or remove this RF module in the user’s manual of the end product which
integrates this module. The end user manual shall include all required regulatory
information/warning as show in this manual.
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, including interference that may cause undesired
operation.
This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. 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 to correct the interference by one of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.
Any changes or modifications not expressly approved by the party responsible for
compliance could void the user's authority to operate this equipment. This transmitter must
not be co-located or operating in conjunction with any other antenna or transmitter.
Radiation Exposure Statement
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled
environment. This equipment should be installed and operated with minimum distance 20
cm between the radiator & your body.
End Product Labeling
When the module is installed in the host device, the FCC ID label must be visible through a
window on the final device or it must be visible when an access panel, door or cover is
easily re-moved. If not, a second label must be placed on the outside of the final device
that contains the following text: “Contains FCC ID: ”NKR-IMG01”
The grantee's FCC ID can be used only when all FCC compliance requirements are met.
This device is intended only for OEM integrators under
the following conditions:
(1) The antenna must be installed such that 20 cm is maintained between the antenna and
users,
(2) The transmitter module may not be co-located with any other transmitter or antenna.
(3) (3) To comply with FCC regulations limiting both maximum RF output power and human
exposure to RF radiation, the maximum antenna gain including cable loss in a mobile exposure
condition must not exceed:
Standalone Condition:
。 10.0 dBi in 700 MHz Band
。 6.0 dBi in 1700 MHz Band
Assuming collocated with a WLAN/WiMax transmitter with maximum 34 dBm average
EIRP power
。 6.5 dBi in 700 MHz Band
。 6.0 dBi in 1700 MHz Band
Remark: This assumption is not valid if the output power of the collocated WLAN/WiMax
transmitter is higher than 34 dBm.
In the event that these conditions cannot be met (for example certain laptop configurations or
co-location with another transmitter), then the FCC authorization is no longer considered valid
and the FCC ID cannot be used on the final product. In these circumstances, the OEM integrator
will be responsible for re-evaluating the end product (including the transmitter) and obtaining a
separate FCC authorization.
To ensure compliance with all non-transmitter functions, the host manufacturer is
responsible for evaluating host system for Part 15 subpart B requirement.
