Design guide
1、Summarize
Flight B2S offers a highly integrated wi-fi solution featuring compact design, reliable
performance, and versatility.
In addition to the wi-fi capabilities, Flight B2S also integrates with the Hi3518V300
series of processors for powerful processing power. Flight B2S enables GPIO port, serial
port and other integrated sensors and other devices to reduce the early development
costs and minimize the use of system resources during operation. The software
development kit
(SDK) provided by Meari contains sample code for a variety of
applications.

10. OEM/Integrators Installation Manual
10.1. List of applicable FCC rules
This module has been tested and found to comply with part 15.247 requirements for Modular Approval.
10.2. Summarize the specific operational use conditions
This module can be used in Wifi-camera. The input voltage to the module should be nominally 4.75-5.25 VDC ,typical
value 5VDC and the ambient temperature of the module should not exceed 50℃. Flight B2S has one PCB antenna
with max antenna gain 2.5dBi .
10.3. Limited module procedures
This module can be used in Wifi-camera. The input voltage to the module should be nominally 4.75-5.25 VDC ,typical
value 5VDC . The limited module manufacturer will reviews detailed test data or host designs prior to giving the host
manufacturer approval.
10.4. Trace antenna designs
NA
10.5. RF exposure considerations
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment .This
equipment should be installed and operated with minimum distance 20cm between the radiator& your body. If the
device built into a host as a portable usage, the additional RF exposure evaluation may be required as specified by§
2.1093.
10.6. Antennas
Antenna type:
PCB antenna
2.4GHz band
Peak Gain
2.5(dBi)
10.7. Label and compliance information
When the module is installed in the host device, the FCC ID/IC label must be visible through a window on the final
device or it must be visible when an access panel, door or cover is easily re-moved. If not, a second label must be
placed on the outside of the final device that contains the following text: “Contains FCC ID: 2ANJC-FLIGHTB2S”
“Contains IC: 25656-FLIGHTB2S“ The FCC ID/IC can be used only when all FCC ID/IC compliance requirements are
met.
10.8.
Information on
test modes and additional
testing
requirements
a) The modular transmitter has been fully tested by the module grantee on the required number of channels,
modulation types, and modes, it should not be necessary for the
host installer to re-test all the available transmitter modes or settings. It is recommended that the host product
manufacturer, installing the modular transmitter,perform some investigative measurements to confirm that the
resulting composite system does not exceed the spurious emissions limits or band edge limits (e.g., where a
different antenna may be causing additional emissions).
b) The testing should check for emissions that may occur due to the intermixing of emissions with the other
transmitters, digital circuitry, or due to physical properties of the host product (enclosure). This investigation is
especially important when integrating multiple modular transmitters where the certification is based on testing each
of them in
a stand-alone configuration. It is important to note that host product manufacturers should not assume that because
the modular transmitter is certified that they do not
have any responsibility for final product compliance.
c) If the investigation indicates a compliance concern the host product manufacturer is obligated to mitigate the
issue. Host products using a modular transmitter are subject to
all the applicable individual technical rules as well as to the general conditions of operation in Sections 15.5, 15.15,
and 15.29 to not cause interference. The operator of the host product will be obligated to stop operating the
device until the interference have been corrected , WIFI testing using QRCT in FTM mode.
10.9. Additional testing, Part 15 Subpart B disclaimer
The final host / module combination need to be evaluated against the FCC Part 15B criteria for unintentional
radiators in order to be properly authorized for operation as a Part
15 digital device.
The host integrator installing this module into their product must ensure that the final composite product complies
with the FCC requirements by a technical assessment or
evaluation to the FCC rules, including the transmitter operation and should refer to guidance in KDB 996369.
For host products with certified modular transmitter, the frequency range of investigation of the composite system is
specified by rule in Sections 15.33(a)(1) through (a)(3), or the range applicable to the digital device, as shown in
Section 15.33(b)(1), whichever is the higher frequency range of investigation
When testing the host product, all the transmitters must be operating.The transmitters can be enabled by using
publicly-available drivers and turned on, so the transmitters are
active. In certain conditions it might be appropriate to use a technology-specific call box (test set) where accessory
devices or drivers are not available. When testing for emissions from the unintentional radiator, the transmitter shall
be placed in the receive mode or idle mode, if possible. If receive mode only is not possible then, the radio shall be
passive (preferred) and/or active scanning. In these cases, this would need to enable activity on the communication
BUS (i.e., PCIe, SDIO, USB) to ensure the unintentional radiator circuitry is enabled. Testing laboratories may need to
add attenuation or filters depending on the signal strength of any active beacons (if applicable) from the enabled
radio(s). See ANSI C63.4, ANSI C63.10 and ANSI C63.26 for further general testing details.
The product under test is set into a link/association with a partnering WLAN device, as per the normal intended use
of the product. To ease testing, the product under test is set to transmit at a high duty cycle, such as by sending a
file or streaming some media content.
