PHY, iyo yemuviri layer yeIEEE 802.11, ine inotevera nhoroondo yekuvandudza tekinoroji uye tekinoroji zviyero:
IEEE 802 (1997)
Modulation tekinoroji: infrared kutapurirana kweFHSS uye DSSS
Operating frequency band: inoshanda mu2.42.4835GHz bhendi (2.42.4835GHz, 83.5MHZ pamwe chete, yakakamurwa kuita 13 chiteshi (5MHZ pakati pematanho ari pedyo), imwe neimwe chiteshi inoverengera 22MHz. migero inopindirana [1 6 11 kana 2 7 12 kana 3 8 13])
Kutapurirana mwero: Panguva ino, mwero wekutapurirana uri kunonoka uye data ishoma.Inogona kushandiswa chete kune masevhisi ekuwana data, uye iyo yakanyanya kutapurirana mwero ndeye 2 Mbps.
Kugarisana: hazvienderani.
IEEE 802.11a (1999)
Modulation tekinoroji: yakaunzwa zviri pamutemo (OFDM) tekinoroji, iyo inonzi orthogonal frequency division multiplexing (OFDM).
Operating frequency band: panguva ino, inoshanda mu5.8GHz frequency band (5.725G5.85GHz, 125MHz zvachose, yakakamurwa kuita nhanho shanu, imwe neimwe chiteshi inoverengera 20MHz, uye chiteshi chepedyo hachipindirane, ndiko kuti, kana nzira dzinoshandiswa panguva imwe chete, idzi nzira shanu hadzipindirani).
Chiyero chekufambisa: kana chiyero chekufambisa chichiwedzera, i54, 48, 36, 24, 18, 12, 9, uye 6. Zvisungo zviri munharaunda iyi Mbps.
Kugarisana: hazvienderani.
IEEE 802.11b (1999)
Modulation tekinoroji: wedzera IEEE 802.11 DSSS modhi uye tora iyo CCK modulation nzira.
Inoshanda frequency bhendi: 2.4GHz
Chiyero chekufambisa: tsigira mitengo yakasiyana ye11 Mbps, 4.5 Mbps, 2 Mbps, uye 1 Mbps
Kugarisana: Tanga kudzika kuenderana neIEEE 802.11
IEEE 802.11g (2003)
Modulation tekinoroji: kuunza orthogonal frequency division multiplexing (OFDM) tekinoroji
Inoshanda frequency bhendi: 2.4GHz
Chiyero chekufambisa: ziva huwandu hwepamusoro hwekufambisa data hwe54 Mbps
Kugarisana: Inoenderana neIEEE 802.11/IEEE 802.11b
IEEE 802.11n (2009)
Modulation tekinoroji: kuunza orthogonal frequency division multiplexing (OFDM) tekinoroji + akawanda ekuisa / akawanda mabudiro (MIMO) matekinoroji.
Inoshanda frequency bhendi: 2.4G kana 5.8GHz
Transmission rate: data transmission speed inogona kusvika 300 ~ 600Mbps
Kugarisana: Inoenderana neIEEE 802.11/IEEE 802.11b/IEEE 802.11a
Izvo zviri pamusoro ndiyo nhoroondo yemaitiro eIEEE802 protocol, iyo isiri yakaoma kuwana.Iyi protocol inosanganisira ese ari maviri 2.4G uye 5G frequency mabhendi.Uyezve, nekuvandudzwa kwenhoroondo uye kudzokororwa nguva dzose kweprotocol, chiyero chiri kukura kumusoro.Parizvino, iyo theoretical yakanyanya kumhanya ye2.4G bhendi inogona kusvika 300Mbps, uye yakanyanya kumhanya yekurekodha ye5G band inogona kusvika 866Mbps.
Pfupiso: Maprotocol anotsigirwa ne2.4GWiFi ndeaya: 11, 11b, 11g, uye 11n.
Maprotocol anotsigirwa ne5GWiFi ndeaya 11a, 11n, uye 11ac.
Zviri pamusoro itsananguro yeruzivo yeWLAN Physical Layer PHY yakaunzwa kwauri neShenzhen Haidiwei Optoelectronics Technology Co., Ltd. Shenzhen Haidiwei Optoelectronics Technology Co., Ltd.zvigadzirwa
