Antennas
The module of SW8021-U has a unique antenna port arrangement for LoRa, which was employed the dipole antenna
with maximum gain is 1dBi. If used different type or higher than 1dBi of antenna, that requires the submission of a
Class II permissive change or new application.
Label and compliance information When the module is installed in the host device, the FCC ID 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 Transmitter Module
FCC ID: 2A4BH-SW8021, the FCC ID can be used only when all FCC ID compliance requirements are met.
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

- 7 -
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 tomitigate 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 .
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 Part15 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 publiclyavailable drivers and turned on, so
the transmitters are active. In certain conditions it might beappropriate 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.
