2. Section2:
2.1
Overview:
RMWIFI-QC operates in the unlicensed 2.4 radio bands IEEE 802.11b/g, which
supports Direct Sequence Spread Spectrum (DSSS) 1 Mb/s and 2 Mb/s data rates,
Complementary Code Keyed (CCK) 5.5 Mb/s and 11 Mb/s data rates and 6Mb/s
to 54Mb/s OFDM .
RMWIFI-QC is based on RMWIFI-M5 module, which contains QC 4004A WIFI
system-on-chip. The QC 4004A have fully integrated RF Transceiver, low power
PA and application processor. Both TX and RX chain in the module incorporate
internal power control loops.
RMWIFI-QC carries onboard single supply monitor for 1.8V voltage supply with
optional module controlled external regulator enable control pin.
The module contains MK22FN1M0VLH12 Microcontroller and QCA4004 Radio.
The QCA4004 single-chip Radio provides a complete 2.4 GHZ & 5 GHz radio
interface between the antenna and the microcontroller. It comprises the analog
radio part, digital modulation and demodulation including time and frequency
synchronization, as well as data buffering. The differential to single ended TX &
RX path conversion is done using lumped balun. Antenna is connected to TX &
RX path using external 2.4 GHz antenna switch. 5 GHz part of the radio is disabled
and not used in this module.

General declaration for FCC and IC
5.1
FCC & IC (Industry Canada)
This device complies with Part 15 of the FCC Rules / Industry Canada
license-exempt RSS standard(s). Operation is subject to the following two
conditions:
1. This device may not cause harmful interference, and
Copyright © 2015 Honeywell Analytics, All rights reserved.

2. This device must accept any interference received, including
interference that may cause undesired operation.
Le présent appareil est conforme aux CNR d'Industrie Canada applicables
aux appareils radio exempts de licence. L'exploitation est autorisée aux
deux conditions suivantes :
1. L'appareil ne doit pas produire de brouillage, et
2. l'utilisateur del'appareil doit accepter tout brouillage radioélectrique
subi, même si le brouillage est susceptible d'en compromettre le
fonctionnement.
Warning:
Changes or modifications not expressly approved by the party responsible
for compliance could void the user's authority to operate the equipment.
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.
Under Industry Canada regulations, this radio transmitter may only
operate using an antenna of a type and maximum (or lesser) gain
approved for the transmitter by Industry Canada. To reduce potential radio
interference to other users, the antenna type and its gain should be so
chosen that the equivalent isotropically radiated power (e.i.r.p.) is not
more than that necessary for successful communication.
Conformément à la réglementation d'Industrie Canada, le présent
émetteur radio peutfonctionner avec une antenne d'un type et d'un gain
maximal (ou inférieur) approuvé pour l'émetteur par Industrie Canada.

Dans le but de réduire les risques de brouillage radioélectrique à
l'intention des autres utilisateurs, il faut choisir le type d'antenne et son
gain de sorte que la puissance isotrope rayonnée équivalente (p.i.r.e.) ne
dépasse pas l'intensité nécessaire à l'établissement d'une communication
satisfaisante.
5.2
MPE (Maximum Radiated Power) Requirements
To satisfy FCC / IC RF exposure requirements, a separation distance of
20 cm or more should be maintained between the antenna of this device
and persons during device operation.
To ensure compliance, operations at closer than this distance is not
recommended.
Les antennes installées doivent être situées de facon à ce que la
population ne puisse y être exposée à une distance de moin de 20 cm.
Installer les antennes de facon à ce que le personnel ne puisse approcher
à 20 cm ou moins de la position centrale de l’ antenne.La FCC des éltatsunis stipule que cet appareil doit être en tout temps éloigné d’au moins 20
cm des personnes pendant son functionnement.
Region Selection
Limited by local law regulations, version for North America does not have
region selection option.
Information for the OEM Integrators
This device is intended for OEM integrators only. Please see the full grant
of equipment document for restrictions.
Label Information to the End User by the OEM or Integrators
If the FCC ID of this module is not visible when it is installed inside
another device, then the outside of the device into which the module is
installed must be label with
“Contains FCC ID: SU3RMWIFI-QC and IC: 20969-RMWIFIQC”.

For a composite system that incorporates devices contained either in a
single enclosure or in separate enclosures connected by wire or cable,
testing for compliance with the standards in this part shall be performed
with all of the devices in the system functioning. If an intentional radiator
incorporates more than one antenna or other radiating source and these
radiating sources are designed to emit at the same time, measurements of
conducted and radiated emissions shall be performed with all radiating
sources that are to be employed emitting. A device which incorporates a
carrier current system shall be tested as if the carrier current system were
incorporated in a separate device; that is, the device shall be tested for
compliance with whatever rules would apply to the device were the carrier
current system not incorporated, and the carrier current system shall be
tested for compliance with the rules applicable to carrier current systems.
