Mo te kawa IEEE802.11 i roto i te WiFi, he maha nga uiuinga raraunga e whakahaerehia ana, a ko te whanaketanga o mua ka whakarapopotohia penei. Ko te whakarāpopototanga e whai ake nei ehara i te rekoata matawhānui me te whai kiko, engari he whakaahuatanga mo nga tikanga e whakamahia ana i te maakete i tenei wa.
Ko te IEEE 802.11, i whakapumautia i te tau 1997, ko te paerewa taketake (2Mbit/s, te haapurororaa i te 2.4GHz). He puhoi tona tere, e whakatakoto ana i te turanga mo nga kawa ahokore.
I hangaia te IEEE 802.11a i te tau 1999. Ko te tikanga hei taapiri i te paparanga tinana (54mbit/s me te roopu auau ko 5GHz).
Ko te IEEE 802.11b, he mea hanga i te tau 1999, he taapiri ki te paparanga tinana 2.4GHz i whakaarohia e 11 (11mbit/s, te haapurororaa i te 2.4GHz).
IEEE 802.11g, 2003, taapiri paparanga tinana (54 mbit/s, 2.4GHz haapurororaa).
IEEE 802.11n. Kua pai ake te tere tuku i raro i tenei kawa. Ka piki ake te reiti taketake ki te 72.2 mbit/s, ka taea te whakamahi i te bandwidth rua o 40 MHz. I taua wa, kua piki ake te reiti ki te 150 mbit/s. Tautoko mo te hangarau maha-whakauru, maha-putanga (MIMO). Ko tenei kawa ka whakapai ake i te roopu auau i waenga i te 2.4GHz me te 5GHz.
Ko te IEEE 802.11ac, ko te kairiiwhi pea o 802.11n, ko te whakapai ake i te tere o te tuku. Ina whakamahia nga teihana turanga maha, ka piki te reiti ahokore ki te 1 Gbps iti rawa, ka piki te reiti hongere kotahi ki te 500 Mbps neke atu. Whakamahia he whanui ahokore teitei ake (80 Mhz-160 MHz, ka whakaritea ki te 40 MHz o 802.11n), he maha ake nga awa MIMO (tae atu ki te 8), me te aratau whakarereke pai ake (QAM256). I whakarewahia te paerewa ōkawa i te Hui-tanguru 18, 2012.
I roto ia ratou, he kawa motuhake. I tua atu i nga paerewa IEEE i runga ake nei, ko tetahi atu hangarau e kiia nei ko IEEE 802.11b + e whakarato ana i te tere whakawhiti raraunga o 22mbit / s i runga i te IEEE 802.11b (2.4GHz band) na roto i te hangarau pBCC.
Kei runga ake nei te whakamaramatanga matauranga o te rarangi paerewa IEEE 802.11 i kawea mai e koeShenzhen HDV Phoelectron Technology Co., Ltd.Ko te tumanako ka awhina tenei tuhinga ki a koe ki te whakanui ake i to matauranga. I tua atu i tenei tuhinga mena kei te rapu koe i tetahi kamupene kaihanga taputapu korero muka whatu pai ka whakaarohia e koemo tatou.
Ko nga hua whakawhitiwhiti i hangaia e te kamupene ko:
Kōwae: kōwae muka whatu, Kōwae Ethernet, kōwae whatu whatu transceiver,SSFP kōwae whatu, aSFP muka whatu, etc.
