Hi expert,

My customer want to know what’s the different between Operating free-air temperature range and Communication free-air temperature range? Thanks a lot!!

(Their required operating ambient temperature is -30C to 70C in general)

Hi Ann,

According to our designer, the tighter range would include the OTP programming range (-20 to 70C).
It appears the wider temp range would not include OTP programming, only basic communciation.

Hope this helped.

Regards,

Nabil
