AGENCY CERTIFICATIONS
4.1
FCC (United States) Certification
STM110C LIMITED MODULAR APPROVAL
This is an RF module approved for Limited Modular use operating as an intentional trans-
mitting device with respect to 47 CFR 15.231(a-c) and is limited to OEM installation. The
module is optimized to operate using small amounts of harvested energy, such as can be
collected by a small solar cell exposed to ambient light. The module transmits short radio
packets comprised of control signals, (in some cases the control signal may be accompa-
nied with data) such as those used with alarm systems, door openers, remote switches,
and the like. The module does not support continuous streaming of voice, video, or any
other forms of streaming data; it sends only short packets containing control signals and
possibly data and is typically powered by a solar cell in ambient light. The module is de-
signed to comply with, has been tested according to 15.231(a-c), and has been found to
comply with each requirement. Thus, a finished device containing the STM110C radio mod-
ule can be operated in the United States without additional Part 15 FCC approval (approv-
al(s) for unintentional radiators may be required for the OEM’s finished product), under
EnOcean’s FCC ID number. This greatly simplifies and shortens the design cycle and devel-
opment costs for OEM integrators.
The module can be triggered manually or automatically, which cases are described below.
Manual Activation
The radio module can be configured to transmit a short packetized control signal if
triggered manually. The module can be triggered, by pressing a switch, for exam-
ple. The packet contains one (or more) control signals that is(are) intended to con-
trol something at the receiving end. The packet may also contain data. Depending
on how much energy is available from the energy source, subsequent manual trig-
gers can initiate the transmission of additional control signals. This may be neces-
sary if prior packet(s) was(were) lost to fading or interference. Subsequent triggers
can also be initiated as a precaution if any doubt exists that the first packet didn’t
arrive at the receiver. Each packet that is transmitted, regardless of whether it was
the first one or a subsequent one, will only be transmitted if enough energy is avail-
able from the energy source.
Automatic Activation
The radio module also can be configured to transmit a short packetized control sig-
nal if triggered automatically, by a relevant change of its inputs, for example.
Again, the packet contains a control signal that is intended to control something at
the receiving end and may also contain data. As above, it is possible for the packet
to get lost and never reach the receiver. However, if enough energy is available
from the energy source, and the module has been configured to do so, then another
packet or packets containing the control signal may be transmitted at a later, un-
predictable time.
OEM Requirements
In order to use EnOcean’s FCC ID number, the OEM must ensure that the following condi-
tions are met.
