WB40NBT Datasheet, PDF (20/26 Pages) Laird Tech Smart Technology – This document describes key hardware aspects of the Laird SDC-WB40NBT wireless bridge module
WB40NBT
Datasheet
 Maximum 5 GHz Gain: 5 dBi
 Tested and Certified 2.4 GHz Transmit Power: 100% of maximum setting (no reduction of power is required
in the 2.4 GHz band)
 Tested and Certified 5 GHz Transmit Power: 100% of maximum setting (no reduction of power is required in
the 5 GHz band)
Note:
If the formal test reports for the SDC-WB40NBT show that transmit power was decreased to less than
100% on 2.4 GHz edge channels, Laird will make these transmit power reductions in firmware for the
edge channels. Integrators do not need to reduce transmit power on a channel-by-channel basis to
comply with band edge regulations.
Antennas of differing types and higher gains may be integrated as well. If necessary, with the Summit
Manufacturing Utility software utility, OEMs may reduce the transmit power of the SDC-WB40NBT to account
for higher antenna gain. In some cases, OEMs may be able to reduce certification efforts by using antennas that
are of like type and equal or lesser gain to the above listed antennas.
9.2 Documentation Requirements
In order to ensure regulatory compliance, when integrating the SDC-WB40NBT into a host device, it is necessary
to meet the documentation requirements set forth by the applicable regulatory agencies. The following sections
(FCC, Industry Canada, and European Union) outline the information that may be included in the user’s guide
and external labels for the host devices into which the SDC-WB40NBT is integrated.
9.2.1 FCC
Note: You must place “Contains FCC ID: TWG-SDCWB40NBT” on the host product in such a location that it
can be seen by an operator at the time of purchase.
9.2.1.1 User’s Guide Requirements
As outlined in the Operational Description, the SDC-WB40NBT complies with FCC Part 15 Rules for a Modular
Approval. To leverage Laird’s grant, the two conditions below must be met for the host device into which the
SDC-WB40NBT is integrated:
1. The antenna is installed with 20 cm maintained between the antenna and users.
2. The transmitter module is not co-located with any other transmitter or antenna that is capable of
simultaneous operation.
As long as the two conditions above are met, further transmitter testing is typically not required. However, the
OEM integrator is still responsible for testing its end-product for any additional compliance requirements
required with this module installed, such as (but not limited to) digital device emissions and PC peripheral
requirements.
IMPORTANT!
In the event that the two conditions above cannot be met (for example certain device
configurations or co-location with another transmitter), then the FCC authorization is
no longer considered valid and the FCC ID cannot 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.
When using Laird’s FCC grant for the SDC-WB40NBT, the integrator must include specific information in the
user’s guide for the device into which the SDC-WB40NBT is integrated. The integrator must not provide
