The six regulatory frameworks that decide how 5 GHz channels and 6 GHz (WiFi 6E) behave.

FCC

United States · Canada · South Korea · Brazil · Saudi Arabia

UNII-1 (36–48) & UNII-3 (149–165) are DFS-free and high-power. UNII-2 (52–144) needs DFS.

36–48Yes (no DFS)

52–64DFS

100–144DFS

149–165Yes (up to 1 W)

160 MHz → 36–64, 100–1286 GHz → Full 5925–7125 MHz

ETSI

EU · UK · Australia · NZ · Singapore · Malaysia · Switzerland · Nordics

Indoor-only below 5.7 GHz. UNII-2 needs DFS. UNII-3 (149–165) generally NOT enabled for WiFi.

36–48Yes (indoor)

52–64DFS (indoor)

100–144DFS

149–165Mostly disabled

160 MHz → 36–64, 100–1286 GHz → Lower 5945–6425 MHz

CN (China)

Mainland China

UNII-2C (100–144) is MISSING entirely. 160 MHz only fits in 36–64. 6 GHz not opened. 5.8G (149–165) is strong & DFS-free.

36–48Yes (indoor)

52–64DFS (indoor)

100–144Not supported

149–165Yes (33 dBm)

160 MHz → 36–64 only6 GHz → Not opened

JP (Japan)

Japan

Like ETSI but with its own W52/W53/W56 bands. UNII-3 (149–165) NOT enabled. 6 GHz lower band opened.

36–48Yes (indoor)

52–64DFS (indoor)

100–144DFS

149–165Not supported

160 MHz → 36–64, 100–1286 GHz → Lower 5945–6425 MHz

KR (Korea)

South Korea

Follows FCC channel plan and opened the FULL 6 GHz band — best WiFi 6E experience outside the US.

36–48Yes (no DFS)

52–64DFS

100–144DFS

149–165Yes

160 MHz → 36–64, 100–1286 GHz → Full 5925–7125 MHz

IN (India)

India

5 GHz broadly allowed (5150–5875). 6 GHz allocation still pending.

36–48Yes

52–64DFS

100–144DFS

149–165Yes

160 MHz → 36–64, 100–1286 GHz → Pending
