PHY, ka papa kino o IEEE 802.11, aia ka mōʻaukala o ka hoʻomohala ʻenehana a me nā kūlana ʻenehana:
IEEE 802 (1997)
ʻenehana hoʻololi: hoʻoili infrared o FHSS a me DSSS
ʻO ka hui alapine hana: e hana ana i ka 2.4GHz frequency band (2.42.4835GHz, 83.5MHZ i ka huina, māhele ʻia i 13 mau ala (5MHZ ma waena o nā kahawai pili), ʻo kēlā me kēia kanal e helu ana i 22MHz. Ke hoʻohana ʻia nā kaha i ka manawa like, aia ʻekolu non- nā kaha ʻāwili [1 6 11 a i ʻole 2 7 12 a i ʻole 3 8 13])
Laki hoʻouna: I kēia manawa, ua lohi ka hoʻouna ʻana a ua liʻiliʻi ka ʻikepili. Hiki ke hoʻohana wale ʻia no nā lawelawe ʻikepili, a ʻo 2 Mbps ka nui o ka hoʻouna ʻana.
Kūlike: ʻaʻole kūpono.
IEEE 802.11a (1999)
ʻenehana hoʻololi: hoʻolauna mua ʻia (OFDM) ʻenehana, ʻo ia hoʻi ka orthogonal frequency division multiplexing (OFDM).
ʻO ka hui alapine hana: i kēia manawa, ke hana nei ia ma ka 5.8GHz alapine (5.725G5.85GHz, 125MHz i ka huina, māhele ʻia i ʻelima mau kahawai, ʻo kēlā me kēia kaila no 20MHz, a ʻaʻole e uhi nā kahawai pili kekahi i kekahi, ʻo ia hoʻi, i ka wā hoʻohana ʻia nā awāwa i ka manawa like, ʻaʻole pili kēia mau kaha ʻelima i kekahi).
Ka nui o ka hoʻouna ʻana: ke piʻi ka nui o ka hoʻouna ʻana, ʻo ia ka 54, 48, 36, 24, 18, 12, 9, a me 6. ʻO nā ʻāpana o kēia pae he Mbps.
Kūlike: ʻaʻole kūpono.
IEEE 802.11b (1999)
ʻenehana hoʻololi: hoʻonui i ke ʻano IEEE 802.11 DSSS a hoʻohana i ke ʻano modulation CCK
Ka hui alapine hana: 2.4GHz
Laki hoʻouna: kākoʻo i nā ʻano like ʻole o 11 Mbps, 4.5 Mbps, 2 Mbps, a me 1 Mbps
Hoʻohālikelike: E hoʻomaka i ka hoʻohālikelike i lalo me IEEE 802.11
IEEE 802.11g (2003)
ʻenehana hoʻololi: hoʻokomo i ka ʻenehana hoʻokaʻawale orthogonal frequency division multiplexing (OFDM).
Ka hui alapine hana: 2.4GHz
Ka nui o ka lawe ʻana: e ʻike i ka nui o ka hoʻouna ʻana i ka ʻikepili o 54 Mbps
Hoʻohālikelike: Kūpono me IEEE 802.11/IEEE 802.11b
IEEE 802.11n (2009)
ʻenehana hoʻololi: hoʻolauna ʻana i ka ʻenehana orthogonal frequency division multiplexing (OFDM) + ʻenehana hoʻokomo/nui (MIMO) ʻenehana
Ka hui alapine hana: 2.4G a i ʻole 5.8GHz
Ka nui o ka lawe ʻana: hiki ke piʻi ka wikiwiki o ka lawe ʻana i ka ʻikepili i 300 ~ 600Mbps
Kaulike: Paʻa me IEEE 802.11/IEEE 802.11b/IEEE 802.11a
ʻO ka mea i luna nei ka hana mōʻaukala o ka protocol IEEE802, ʻaʻole paʻakikī ke loaʻa. Loaʻa kēia protocol i nā pūʻulu alapine 2.4G a me 5G. Eia kekahi, me ka hoʻomohala ʻana o ka mōʻaukala a me ka hoʻoponopono mau ʻana o ka protocol, ke ulu nei ka helu i luna. I kēia manawa, hiki i ka 2.4G ke kiʻekiʻe kiʻekiʻe o ka wikiwiki a hiki i ka 300Mbps, a hiki i ka 866Mbps ka wikiwiki o ka hoʻopaʻa ʻana o ka band 5G.
Hōʻuluʻulu manaʻo: ʻO nā protocols i kākoʻo ʻia e 2.4GWiFi: 11, 11b, 11g, a me 11n.
ʻO nā protocols i kākoʻo ʻia e 5GWiFi ʻo 11a, 11n, a me 11ac.
ʻO ka mea ma luna nei ka wehewehe ʻike o WLAN Physical Layer PHY i lawe ʻia mai iā ʻoe e Shenzhen Haidiwei Optoelectronics Technology Co., Ltd. He mea hana ʻo Shenzhen Haidiwei Optoelectronics Technology Co., Ltd.huahana
