MIC revised the certification rules for low-power data communication systems in the 5GHz band

Jul 25, 2019
To revise Article 2 Paragraph 1 of item 19-3 with new certification ordinance (Category code: XA), it will replace the current Article 2 Paragraph 1 of item 19-3 (Category code: XW), Article 2 Paragraph 1 of item 19-3-2 (Category code: YW) and Article 2 Paragraph 1 of item 19-3-3 (Category code: HS).
There is an one year transition period from 11th July 2019 to enforce the revised certification rule of Article 2-1-19-3(XA) and the old certification rule of Article 2-1-19-3, Article 2-1-19-3-2 and Article 2-1-19-3-3 will no longer effective till 11th July 2020. The old certification rule certificate still valid even 12th July 2020 or later.
