EXECUTIVESUMMARYAproperreviewofeverydeviceshippedisanimportantsteptosecureacorrectfunctioningofeverysingledevice,especiallytoensureaworkinginteroperability.

The EnOcean Alliance developed and agreed upon a specification which describes thecertification steps to be passedby every device before being introduced into themarket(s).Thesestepsare:

(1) AirInterface(2) RadioPerformance(3) CommunicationProfiles(4) EnergyHarvestingofSelfsupplieddevices

Thisdocumentspecifiespart(1a)AirInterface(ASK)1whichisamandatorypartoftheEnOceanCertificationProgram.Goalofthispartistoassesstheradiointeroperabilityofthedeviceundertest(DUT)withotherdevices(existingorfuture)intheEnOceanecosystemwhichisbasedontheISO/IEC14543-3-10standard[1].

7.2.2. Centerfrequencytest

Center frequency is the frequency at which the receiver shows the best demodulationcapabilities. No specific measurement for center frequency is required; it is sufficient todemonstrate that the receiver achieves the requiredperformance for the test casesdefinedbelow.

7.2.3. SensitivityandMaximumPowerLevel

7.2.3.1. Definition

SensitivityistheminimumRFinputpowerlevelatwhich(orbelow)thebiterrorrateexceedsadefinedvalueduetonoise.MaximuminputpowerlevelistheRFlevelatwhichaDUTisabletoreceiveanddecodeastrongRFsignalatadefinedbiterrorrate.


MeasurementsshallbemadeunderStandardandExtremeconditionsasdefinedinchapter4.4.7.2.3.3. Measurementprocedure

TheISO14543-3-10standard[1]definesthatabiterrorrateof0.1%shallbeusedtodeterminethesensitivity.AnRFinputpowerlevelof-95dBmshallbesufficienttoreachthisbiterrorrateaccording to the standard. No operating conditions are specified in conjunction with thatrequirement.

The definition based on the bit error rate in [1] was chosen to establish a metric that isindependentofthesubtelegramorframestructure.However,fromacertificationperspectivethis approach is not optimal. Experience with current solutions has shown that manydemodulationerrorsoccuronsubtelegramorframelevel(notbitstreamlevel)andarecausedbyissuessuchasincorrectpreambledetectionorincorrectdemodulationsettings(statichighlevel / low level). To be able to detect such issues, certification testing will be made onsubtelegramlevel.

In order to do so, an equivalent subtelegram (or packet) error rate PER is derived from thespecified bit error rate (BER) of 0.1% togetherwith the known number of bits (NoB) of thereferencesubtelegramdefinedinAnnexAwhichis138bit(completetelegramincludingSOFandEOF,butwithoutpreamble).ThesubtelegramerrorratePERwhich isequivalenttoabiterrorrateof0,1%forasubtelegramsizeof138bitistherefore:



𝑃𝐸𝑅=1−(1−𝐵𝐸𝑅)𝑁𝑜𝐵=1−(0.999)138=12.9%

PerformanceoftheDUTisingeneralaffectedbythesupportedoperatingconditions(especiallythesupportedtemperaturerange).DUTsupportingawidetemperaturerangetypicallywillhaveless performance compared to DUT supporting only operation at room temperature due toparametervariation(e.g.incrystalfrequency).

Measurement has to consider this aspect while at the same time ensuring a minimumperformanceforallDUTirrespectiveoftheirsupportedoperatingconditions.

Thefollowingcompensationfactorbetween0dBand3dBcanthereforebeusedforDUTduringsensitivityandmaximumpowerleveltesting:

SupportedOperationTemperatureRange(Tmax–Tmin) CompensationFactor

<40°C 0dB

40°C…79°C 1dB

80°C…119°C 2dB

Please,note:thecustomerdocumentationoftheDUT(Datasheet/UserManual)shallusetheactualsensitivity(withoutcompensationfactor)toavoidambiguities.

Thegraphshownaboveshallbeobtainedasfollows:

1) The graph shall be obtained from a series of data points where each data pointrepresentsthesubtelegramerrorrateforagiveninputsignalstrength.

2) The subtelegram error rate is calculated based on at least 250 subtelegrams of 4BSreferencetelegramtype1asdefinedinAnnexA(A1.1.)usingthestandardmodulationschemeMS0asdefinedaboveatthecenterfrequencyof868300MHzwiththepowerlevel corresponding to the data point. For each subtelegram, the correct frame(including the required preamble, start of frame, end of frame and inverse bits) isgeneratedbythesignalgeneratorandpresentedtotheRFinputoftheDUT.Thetimedifferencebetweentwoframesshallbeatleast150ms.

3) TheDUTdecodestheframeandfeedsbackthedecodedsubtelegramcontenttothetestsystemwhereit iscomparedwiththeexpectedcontent(4BSreferencetelegramtype 1, A 1.1.).

7.2.4. Blocking

Blocking is the ability to reject unwanted signals in frequencies adjacent to the operatingfrequency.WithintheEUlegislativeframework,blockingisnowtestedaspartofEN300220radiotesting.TheDUTshallachieveatleastclass2blockingperformance.

Compliancewith this requirement has to be demonstrated as part of radio approval testingwithintheEuropeanUnionandisthereforenotseparatelytestedaspartofEnOceanAlliancecertification.

7.2.5.1. Definition

Demodulation robustness is the ability to correctly decodeRF input signalswith parametersdeviatingfromtheidealvalues.ConsideringthevarietyofdeviceswithintheEnOceanAllianceecosystem, demodulation robustness is a key capability and therefore has to be extensivelytested.


The measurement shall be made under normal and extreme test conditions as defined inchapter4.4.
