8. LEGAL ISSUES AND APPROVALS
USB gateways have been tested to fulfil the requirements of RED (USB 300), FCC/ISED
(USB 300U) and ARIB (USB 400J) based on the radio module hardware and the built-in
firmware.
Radio Equipment Directive (RED) for the European Union
The Radio Equipment Directive (2014/53/EU, typically referred to as RED) replaces the old
R&TTE directive from 1999 as regulatory framework for radio products in the European Un-
ion. All products sold to final customers after 12th of June, 2017 have to be compliant to
RED. At the time of writing, the text of the RED legislation was available from this link:

Duty cycle lock for 868.3 MHz
In order to ensure the 1% duty cycle is not exceeded a watcher is implemented in firm-
ware. This watcher limits the transmission of telegrams beyond the defined 1 % boundary.
The EnOcean Duty cycle watcher implementation works as follows: the 60 minute regula-
tory interval is divided into 10 rolling time slots of equal length. For each of these time
slots, the total transmission time is recorded. In addition to that, the transmission time in
the current time slot is recorded. New telegrams will only be transmitted if the total trans-
mission time in the previous 10 time slots (representing a full 60 minute interval), the
transmission time in the current time slot, and the transmission time of the current tele-
gram combined do not exceed the regulatory limit. The time slots are rotating, freeing al-
ways the last slot.
