NCC Low Power Radio Frequency Technical Specification Update
Since NCC opened Wi-Fi 6E in August 2023, NCC has been revising and improving the technical requirements of Wi-Fi 6E. Finally, on February 6, 2024, the low-power radio frequency equipment technical specification LP0002 version 113 was released, mainly to update Chapter 5.13 of Wi-Fi 6E, and the content of other chapters has not been changed.

The main update of LP0002 version 113 adds a new chapter 5.13, which points out that the working frequency band of 6 GHz wireless access systems including Radio Local Area Network (WAS/RLAN) equipment is: 5.945 GHz ~ 6.425 GHz . Consistent with CE, NCC did not open the conventional Wi-Fi 6E Band 5 frequency band of 5925 MHz ~ 6425 MHz, but reduced the low frequency band by 20 MHz (5925 MHz → 5945 MHz).

LP0002 version 113 provides the following device categories and subcategories for 6 GHz WAS/RLAN (consistent with CE):

Note: In addition to the differences in Power and PSD Limit between LPI and VLP, there are also differences in the Limit of unnecessary out-of-band emissions (i.e. 00B of EN 303 687). VLP equipment will be more stringent. In addition, LPI devices have more restrictions than VLP in terms of equipment restrictions. For example, LPI AP and Bridge devices can only be powered by wires, and the antennas cannot be replaced.

To apply for LP0002 version 113 certification, you need to perform the following items:

In early January 2024, NCC issued instructions that there are the following two methods for applying for the Wi-Fi 6E (5945 MHz ~ 6425 MHz) frequency band, and a transition period is provided.

LP0002

buffer provisions

Before December 31, 2024

(Last acceptance date of the 109th edition)

From January 1, 2025, only the 113th version of the standard will be accepted

Wi-Fi 6E(5945 MHz~6425 MHz)

buffer provisions

Before June 30, 2024

(Last receipt date for EN 303 687 NCC)

From July 1, 2024, only LPO002 can be used to apply for inspection.

Competent Authority (NCC)

Certification body (RCB) commissioned by NCC

Remark

The delivery method adopts a two-stage delivery method.

The competent authority will open the submission ladder from time to time.

Currently, the first-tier NCC only accepts three RCB submissions)

RCB can only accept applications for inspection if it has inspection qualifications
