3 RF Exposure conditions

3.1 Installation Instructions

The module is approved for use in a mobile RF exposure environment. A minimum separation

distance of 20 cm must be maintained between the antenna and nearby persons.

The module is not approved for co-location with any other modules.

3.2 Warning

A warning must be placed in the host product user instructions stating that:

1) “This device is approved for use in a mobile rf exposure environment. A minimum

separation distance of 20 cm must be maintained between the antenna and nearby

persons.”

2) The module is not approved for co-location with any other modules.

The host integrator must follow the integration instructions provided by the module

manufacturer and ensure that the composite-system end product complies with he FCC

requirements by a technical assessment or evaluation to the FCC rules and KDB Publication

996369.

If the required separation distance of 20 cm cannot be fulfilled, a SAR evaluation must be

performed. This consists of additional calculations and/or measurements. The result must be

added to the grant file as a Class II Permissive Change.

4 Antenna interfaces:

4.1 Wi-Fi and Bluetooth antennas

JODY-W2 provides two antenna pins, one for dual-band Wi-Fi connectivity (ANT1) and another

for Bluetooth (ANT0). The following recommendations apply to developing an antenna interface

for the JODY-W2 module:

• Where possible, consider integrating in the end product the u-blox Antenna Reference

Design to minimize the effort on the certification process.

• The ANT0 and ANT1 pins of JODY-W2 have a nominal characteristic impedance of 50 Ω

and must be connected to the external antennas through a 50 Ω transmission line to

allow proper RF transmission and reception.

• Good isolation must be provided between the various antennas in the system. Special

care shall be taken to maximize isolation between the antennas operating in the same or

nearby bands.
