Explanation of CE - RED Instruction of EU 2.4G Product
In February this year, the EU has announced a complete 2.4G products (WIFI, BT, ZigBee) RED directive standards, the majority of manufacturers can now begin to apply for the RED NB certificate!
The CE-RTTE directive standards are as follows:
EMC:ETSI EN301489-1 V1.9.2; ETSI EN301489-17V2.2.1
RF:ETSI EN300328 V1.9.1
SAR:ETSI EN62479
LVD:ETSI EN60950/EN60065
The CE-RED directive standards are as follows:
EMC:ETSI EN301489-1 V2.1.1; ETSI EN301489-17V3.1.1
RF:ETSI EN300328 V2.1.1
SAR:ETSI EN62479
LVD:ETSI EN60950/EN60065
From the standards of EMC and RF RED instructions in the test standard is updated, the standard test content, 300328 EN V2.1.1 than the V1.9.1 test more stringent, whether restricted or test methods, to remind the majority of manufacturers friends phase of product development will need to consider more technical specifications to meet product certification standards;
2、 V2.1.1 (RED) and V1.9.1 (R&TTE) Standard Version of what is the difference between the two?
After the release of EN300328 V2.1.1, and we are now being applied to the standard V1.9.1 do the following differences.
1, the corresponding version of the directive is different: V1.9.1 R&TTE (1995/5/EC) / new version of V2.1.1 (2014/53/EU) RED;
2, define the receiver band 2400-2483.5 MHz;
3, adaptive testing requirements;
The a (TL) can be used to correct the gain (G) of the antenna components (Y), but the beamforming gain should not be considered.
B, change TL formula TL = -70 dBm/MHz + 10 x log10 (100mW/Pout).
C, chapter 5.4.6.2.1.2 self adaptive frequency hopping device using the DAA and 5.4.6.2.1.3 sections using non FHSS non adaptive modulation device based on LBT, for only using multiple reception chain system a link (antenna port) needs to be tested, all the other receiver input should be terminated.
4, receiving blocking test in the V1.9.1 version of the frequency hopping and non FM reception blocking technology is only one requirement, the new version of the distinction between the three types of different requirements;
5, power spectral density of the product is divided into two kinds of definitions Option & Option 2, and changed the scanning time;
6, for the TX/RX RF receiver in the RSE under the two modes, clearly define the difference of ERP/EIRP; E.R.P is limited to 1GHz below the RF; E.I.R.P is more than 1 GHz rf;
7, frequency hopping interval test:
A, for 5.4.5.2.1.2 Option 1 step 1 scanning time from the original 1s to automatic;
B, for 5.4.5.2.1.2 Option 1 step on the requirements of the frequency hopping interval from the original -20 dBc Bandwidth change to Occupied ChannelBandwidth Channel;
C, 5.4.5.2.1.3 Option 2 for the detection of the way in the original RMS changed from Max to Peak, scanning time from the original 1s to automatic.
8, the test receiver blocking, the most obvious change is the V2.1.1 standard in a test, the V1.8.1 and V1.9.1 standard specifies only adaptive equipment and e.i.r.p. is larger than 10dBm devices need to be tested in the receiver blocking, V2.1.1 version of the standard mandatory testing, the definition is different, the limit value is more strictly, but also increased the receiver types.
Test requirements:
After the standard test method and the corresponding blocking signal are added, the receiver error rate (PER) is less than or equal to 10%, and the manufacturer can also declare the alternative performance standards.
In the test, it is necessary to add different frequency and power blocking signals according to different receiver types and meet the requirements of PER less than 10%.
3、 when the 2.4G product CE-RTTE directive expired?
In June 2016 last year, the EU announced the latest CE-RED directive is, it has been clear that the CE-RTTE directive in the failure in June 2017
4、 2.4G products for CE-RED testing, but how to do?
Because the latest CE-RED directive 300328 V2.1.1 requires a very strict test of the receiving side, most of the basic product testing will be unqualified (unless we are pure emission products, without receiving).
Our laboratory equipment has been able to meet the test V2.1.1, you can come to our side of the test side of the rectification.
