Short answer
The 2400MHz band supports broadband wireless access including WLAN, Bluetooth and point-to-point links. The 5100MHz band supports broadband wireless access but is limited to indoor use and excludes use inside automobiles. The 5800MHz band supports broadband wireless access, point-to-point links and electronic toll collection. No station or device has exclusive use of these shared bands.
For equipment in these bands, the RF unit and antenna must be integrated or designed and produced with synchronized matching. Users may not substitute another antenna or add an RF power amplifier. Equipment generally needs radio transmitting equipment model approval, except qualifying micro-power short-range equipment governed by MIIT Announcement 2019 No. 52.
- Equipment in 5250-5350MHz must use dynamic frequency selection () with no disable option and transmit power control () with a range of at least 6 dB. Without TPC, both and EIRP spectral-density limits are reduced by 3 dB.
- Equipment in all three bands must meet one of the interference-avoidance methods in Annex 2. The official interpretation describes listen-before-talk, monitoring and avoidance, or an equivalent occupancy rate no greater than 10 percent.
- A WLAN device that assigns public-network IP addresses must support IPv6 and enable IPv6 address assignment by default. Since 1 December 2023, the model-approval test also checks IPv6 capability; the product must retain a user configuration option and explain configuration in its instructions. This condition does not apply merely because a product has Wi-Fi.
- Equipment subject to special national information-security requirements must also meet the GB 15629 WLAN air-interface access-control security series.
Articles 1-4 and Annexes 1-2 establish the band uses, antenna design, model approval, DFS, TPC, interference-avoidance, IPv6 and security conditions.
Explains the multi-antenna, unwanted-emission and interference-avoidance changes, including the equivalent-occupancy method.
Requires testing from 1 December 2023 for WLAN equipment with public IP address assignment and specifies default enablement, user configuration and instruction content.
