6. Antenna
Antenna type: PCB antenna; Peak gain: 3.40dBi
7. Label and compliance information
An exterior label on OEM’s end product can use wording such as the following:
“Contains Transmitter Module FCC ID: 2AC7Z-ESP32WROOM32E” or
“Contains FCC ID: 2AC7Z-ESP32WROOM32E.”
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 .
