EMC Compliance
5.1
Summary
The TiWi5 module has been tested and approved as a Modular Radio in accordance with the
appropriate FCC and IC standards. The supporting test data may be found in the modular test
report.
Since this module and its associated set of approved antennas have been certified as a Modular
Radio, this allows the end user to integrate this module into an end-product without the
requirement of re-certifying the radio module. The module-integrator is responsible for the
unintentional conducted and radiated emissions and must
verify
that the integrated product is
compliant with the rules associated with unintentional radiators. The module integrator is also
required to maintain an engineering record of the verification testing and declare on the product
through proper labeling and marking that the device is compliant with these particular rules.
The installed module’s FCC ID and IC numbers need to be clearly marked on the product with the
following verbiage “contains FCC ID: TFB-TIWI501” and "contains IC: 5969A-TIWI501".
The TiWi5 has been certified for use in a mobile configuration, which employs a minimum
separation distance of 20 cm from the antenna to the human body or another transmitting
radio. For separation distances of 20 cm or less, the module integrator must have the module
certification re-evaluated, which will include a modification to the existing certification and
additional testing for exposure and SAR requirements.
The TiWi5 module was not certified as a DFS Master, and therefore the AP mode is not allowed
in the 5 GHz bands. The AP mode is allowed to be used in the 2.4 GHz band. Software cannot
prevent the usage of the AP mode in the 5 GHz band, so it is the module-integrators
responsibility to ensure the 5 GHz AP mode is not used.

Module Integration Considerations – Antenna Systems
The module must be used with one of the approved antennas:
1.
LS Research 001-0009 center-fed dipole antenna and LS Research 080-0001 U.FL to
Reverse Polarity SMA connector cable.
2.
Johanson 2450AD46A5400E 2.4/5.4 GHZ Dual Band Chip Antenna.
The antenna should be placed such that it is minimally disturbed by the product’s packaging
material. The incorporation of the largest practical free-space clearance around the antenna is
important for maximizing overall performance. Further, the antenna must be placed such that at
least a 20 cm separation distance is maintained from the human body to the antenna and all
other radio transmitters.
