Module RF compliance limits
The RF compliance limits are those tested for FCC and CE certification using the dedicated
DONGLE (PC92A.V01). These limits are enforced by the DONGLE firmware. Care must be taken
with custom application firmware to ensure these limits are not exceeded, voiding the FCC and CE
certification.

Module RF typical performances
The RF performances of the SPSGRF-868 and SPSGRF-915 modules are depending from many
factors, related to the Customer hardware application board where the module is connected and
also to the Customer application firmware. To give some basic information to the Customer which
will be the module integrator, may be useful to furnish the RF measures taken in an anechoic
chamber using a dongle with inside connected the SPSGRF-868 or the SPSGRF-915 module.

6 Hardware design notes
SPSGRF-868 and SPSGRF-915 modules support SPI hardware interfaces.
Notes
All unused pins should be left floating; do not ground.
All GND pins must be well grounded.
The area around the module should be free of any ground planes, power planes, trace
routings, or metal for 6 mm from the module antenna position, in all directions.
Traces should not be routed underneath the module.
7 Reflow soldering
The SPSGRF is a surface mount SubGiga Transceiver module supplied on a 11 pin, 4-layer
PCB. The final assembly recommended reflow profiles are indicated here below.
Soldering phase has to be executed with care: In order to avoid undesired melting
phenomenon, particular attention has to be taken on the set up of the peak temperature.
Here following some suggestions for the temperature profile based on IPC/JEDEC
J-STD-020C, July 2004 recommendations.

Regulatory compliance
FCC certification
This module has been tested and found to comply with the FCC part 15 rules. These limits
are designed to provide reasonable protection against harmful interference in approved
installations. 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 may not occur in a particular installation.
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.
Modifications or changes to this equipment not expressly approved by STMicroelectronics
may render void the user's authority to operate this equipment.
Modular approval
FCC ID: S9NSPSGRF
In accordance with FCC part 15, the SPSGRF-915 is listed as a modular transmitter
device.
This module is evaluated for stand-alone use only. Finished products incorporating
multiple transmitters must comply with colocation and RF exposure requirements in
accordance with FCC multi-transmitter product procedures. Collocated transmitters
operating in portable RF Exposure conditions (e.g. <20cm from persons including but not
limited to body worn and hand held devices) may require separate approval.
Labeling instructions
When integrating the SPSGRF-915 into the final product, the OEM must ensure that the
FCC labeling requirements are satisfied. A statement must be included on the exterior of
the final product which indicates the product includes a certified module. The label should
state the following (or similar wording that conveys the same meaning):
Contains FCC ID: S9NSPSGRF
OR
This product contains FCC ID: S9NSPSGRF
The OEM must include the following statements on the exterior of the final product unless
the product is too small (e.g. less than 4 x 4 inches):
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
P a g e | 14
Rev 1.0
SPSGRF
must accept any interference received, including any interference that may cause
undesired operation.
Product manual instructions
This section applies to OEM final products containing the SPSGRF-915 module, subject to
FCC compliance. The final product manual must contain the following statement (or a
similar statement that conveys the same meaning):
WARNING: Changes or modifications not expressly approved by the party responsible
for compliance could void the user’s authority to operate the equipment. (Part. 15.21)
In the case where an OEM seeks Class B (residential) limits for the final product, the
following statement must be included in the final product manual:
NOTE: 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 or more 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.
In the case where an OEM seeks the lesser category of a Class A digital device for the final
product, the following statement must be included in the final product manual:
NOTE: This equipment has been tested and found to comply with the limits for a Class A
digital device, pursuant to part 15 of the 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 instruction manual,
may cause harmful interference to radio communications. Operation of this equipment in a
residential area is likely to cause harmful interference in which case the user will be
required to correct the interference at his expense.
