MEARI R831 Camera WiFi Module User Manual
Introduction
The R831 Camera WiFi Module is a highly integrated single-chip 802.11a/b/g/n 1T1R WLANwith USB 2.0 multi-function. It combines a WLAN MAC, a 1T1R capable WLAN baseband and WLANRFin a chip. The R831 provides a complete solution for a high-performance integrated wireless LA controller. The R831 WLAN baseband implements Orthogonal Frequency Division Multiplexing (OFDM) with 1 transmit and 1 receive path and is compatible with the 802.11n specification.
Wi-Fi Dual-band 1×1 802.11a/b/g/n, The wireless module complies with IEEE 802.11 a/b/g/n standard and The high-speed FFT/IFFT paths, combined with BPSK, QPSK, 16QAM, and 64QAMmodulation of the individual subcarriers and rate compatible punctured convolutional coding with coding rate of 1/2, 2/3, 3/4, and 5/6, provide higher data rates of 54Mbps and 150Mbps for 802.11g and 802.11n OFDM respectively.
Important Notice to OEM integrators
- This module is limited to OEM installation ONLY.
- This module is limited to installation in mobile or fixed applications, according to Part 2.1091(b).
- The separate approval is required for all other operating configurations, including portable configurations with respect to Part 2.1093 and different antenna configurations
- For FCC Part 15.31 (h) and (k): The host manufacturer is responsible for additional testing to verify compliance as a composite system. When testing the host device for compliance with Part 15 Subpart B, the host manufacturer is required to show compliance with Part 15 Subpart B while the transmitter module(s) are installed and operating. The modules should be transmitting and the evaluation should confirm that the module’s intentional emissions are compliant (i.e. fundamental and out of band emissions). The host manufacturer must verify that there are no additional unintentional emissions other than what is permitted in Part 15 Subpart B or emissions are complaint with the transmitter(s) rule(s).
The Grantee will provide guidance to the host manufacturer for Part 15 B requirements if needed.
IMPORTANT NOTE:
In the event that these conditions can not 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 can not 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.
**End Product Labeling
**
The final end product must be labeled in a visible area with the following: “Contains Transmitter Module FCC ID:2AG7C-R831 or Contains FCC ID:2AG7C-R831 ”.
Manual Information to the End User
The OEM integrator has to be aware not to provide information to the end user regarding howto install or remove this RF module in the user’s manual of the end product which integrates this module. An intentional radiator shall be designed to ensure that no antenna other than that furnished by the responsible party shall be used with the device. The use of a permanently attached antenna or of an antenna that uses a unique coupling to the intentional radiator shall be considered sufficient to comply with the provisions of antenna requirements according to 15.203.
Federal Communication Commission Interference Statement This equipment has been tested and foundto 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
FCC Caution:
Any changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate this equipment. 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
FCC Radiation Exposure Statement:
This equipment complies with FCC/IC radiation exposure limits set forth for an
uncontrolled environment
The module must be installed in the host device. This End equipment should be
installed and operated with a minimum distance of 20cm centimeters between the
radiator and your body. This transmitter must not be co-located or operating
in conjunction with any other antenna or transmitter
(i) the device for operation in the band 5150-5250 MHz is only for indoor use
to reduce the potential for harmful interference to co-channel mobile
satellite systems;
(ii) the maximum antenna gain permitted for devices in the bands 5250-5350 MHz
and 5470-5725 MHz shall comply with the e.i.r.p. limit; and
(iii) the maximum antenna gain permitted for devices in the band 5725-5825 MHz
shall comply with the e.i.r.p. limits specified for point-to-point and non
point-to-point operation as appropriate.

2.2 List of applicable FCC rules
CFR 47 FCC Part 15 Subpart C and F has been investigated. It is applicable to
the modular transmitter
2.3 Specific operational use conditions
This module is stand-alone modular. If the end product will involve the
Multiple simultaneously transmitting condition or different operational
conditions for a stand-alone modular transmitter in a host, host manufacturer
have to consult with module manufacturer for the installation method in end
system

2.9 Information on test modes and additional testing requirements
Host manufacturer installed this modular with single modular approval should
perform the test of radiated emission and spurious emission according to FCC
part 15C, Part 15E, 15 .209, 15 .207 requirement, only if the test result
comply with FCC part 15C, Part 15E, 15.209, 15.207 require1nent, then the host
can be sold legally.
2.10 Additional testing, Part 15 Subpart B disclaimer
Host manufacturer is responsible for compliance of the host system with module
installed with all other applicable requirements for the system such as Part
15 B.
2.11 Note EMI Considerations
Host manufacture installed this modular with single modular approval should be
recommending “best practice” RF design engineering testing and evaluation in
case non- linear interactions generate additional non- compliant limits due to
module placement to host components or properties.
Host manufacture installed this modular with single modular approval should be
recommending “For EMC/radio-parameter compliance purposes, when an evaluation
is done by the grantee or host provider (see Clause IX in KDB Publication
996369 D01) and there are no additional emissions generated due to
simultaneous-transmission operations compared to single transmitter operations
testing (i.e., not transmitting simultaneously), it is not necessary to file
the additional simultaneous transmission test data.
The host manufacturer is responsible for ensuring compliance with the
applicable FCC rules for the transmitters operating individually and
simultaneously. This includes compliance for the summation of all emissions
from all outputs occupying the same or overlapping frequency ranges, as
defined by the applicable rules.
