hi support team,
customer is asking us about 54L15 or 54LM20 RF performance test result, and i am not sure there is any report for customer for below requests:
1.
TIS ≤ −100 dBm. The difference between the worst and best channels shall be ≤2 dB. Sensitivity degradation under any operating mode (LED/display/sensor enabled) shall be ≤3 dB. Within 80% of the azimuth on the horizontal plane, the variation shall be ≤6 dB.
2.
TRP ≥ +8 dBm, peak EIRP ≤ +10 dBm, EVM ≤15%, frequency offset ≤±20 ppm, spurious margin for EN 300 328 ≥6 dB.
3.
With the wanted signal 3 dB above the unit’s measured sensitivity, the PER shall remain ≤1% under the following conditions:
(a) Co-channel IEEE 802.15.4 interferer is 3 dB below the wanted signal;
(b) Adjacent channel interferer offset by ±5 MHz is at least 35 dB above the wanted signal;
(c) Interferer offset by ±10 MHz is at least 45 dB above the wanted signal;
(d) IEEE 802.11n 20 MHz interferer at −40 dBm with center frequency offset ≥15 MHz from the Thread channel;
(e) LTE interferer at −20 dBm within the frequency bands of 2300–2400 MHz and 2500–2690 MHz.
54L15 or 54LM20 is not determined, any report would be appreciated.
Regards,
William.
