Approval and usage
The 1218RF module has been designed to meet FCC (US) and ETSI (Europe) regulations.
4.1
FCC compliance
This device complies with part 15 of the FCC rules
Operation is subject to the following two conditions:
(1) this device may not cause harmful interference, and
(2) this device must accept any interference received, including interference that may cause undesired operation.
Changes or modifications not expressly approved by the party responsible for compliance could void the user’s
authority to operate the equipment. This in particular is applicable for the antenna which has been delivered with the
system.
To comply with FCC RF exposure requirements for mobile transmitting devices, this transmitter should only be used or
installed at locations where there is at least 20cm separation distance between the antenna and all persons.
4.2
FCC ID
The FCC ID for the 1218RF module is: 2AF88-1218RF.
4.3
FCC labeling requirements
The 1218RF modules are labelled with their own FCC ID; if this FCC ID is not visible from the outside of the finished
product, the finished product must be labelled with the FCC ID.
Contains FCC ID: 2AF88-1218RF

Adaptive Frequency Hopping
The purpose of using frequency hopping in a radio system is to provide diversity that allows data throughput to be
maintained even if interfering radio systems or the physical environment (multipath fading) renders some RF channels
unusable. In the 2.4 GHz ISM band, the sheer amount of radio systems and the severity and dynamic nature of indoor
fading phenomena in typical operating environments require the use of this kind of diversity if a minimum data
throughput is to be assured (as audio streaming requires)
Frequency hopping systems can either implement a fixed sequence of channel hops or adapt its hopping sequence
dynamically to the changing environment it operates in. In order to maximize its own chances of delivering audio data
