Option CloudGate - Last updated on 14/05/2014
Certification of third-party expansion cards
Option offers third-party hardware developers the possibility to design their own expansion cards for the
CloudGate. The CloudGate and the Option expansion cards are compliant with the necessary
regulatory requirements, but third-party hardware developers should still make sure the final product
remains compliant when inserting their expansion cards into the CloudGate.
Before placing these tailor
made expansion cards in the market, it’s the hardware developer's task to evaulate its expansion card for
continued compliance. This page aims to give some initial guidance on the amount of certification that is
needed.
The regulatory requirements for expansion cards are typically concerned with the correct use of the
radio spectrum, EMC, safety and health regulations. They check if the product is working according to
RF regulations and is safe for use; for example, no unwanted emissions, not too high power emissions,
the effective use of RF spectrum, etc. Finally, also correct labeling and information to the end user is
needed.
The amount of testing and certification work highly depends on the supported functionality. Digital
devices containing no wireless transmitter can still transmit unwanted emissions (unintentional radiators)
which can interference with other devices. Devices containing a wireless transmitter should make sure
their RF behavior is within specification and meets safe limits for people.
The most common regulatory approvals are described now.
Federal Communications Commission (FCC)
When selling/operating you own expansion card in the USA, it shall comply with the rules of the Federal
Communications Commission. When the expansion card contains a wireless transmitter, more testing
will be need than when the expansion card doesn’t have a wireless transmitter.
Expansion card without wireless transmitter
Even when a digital device contains no wireless transmitter, it can still emit RF noise and cause
interference to other digital devices. To tackle this, the FCC has imposed rules for these “unintentional
radiators”. The FCC requirements can be found in FCC Part 15,
subpart B “unintentional radiators”.
Depending on the type of Part 15B device, a different equipment authorization procedure is required.
Most expansion cards will fall in the category "Class A digital devices, peripherals & external switching
power supplies” and will be subject to the "Verification" method. This means testing the conducted
and radiated emissions and keeping the test results on record, while no FCC logo or FCC ID is needed.
These FCC Part15, subpart B tests can be executed in authorised test labs.
Expansion card with wireless transmitters
Expansion cards with wireless transmitters shall still comply with the requirements for the non-transmitting
parts explained above. In addition one should check the requirements for the specific frequency of
