munhu wese vaigara muguta ano vanhu vakawanda vakawanda anofanira kuziva kana zvinokuvadza Wi-Fi kuti utano. Uye hazvina basa, kana anoshandisa serura, kombiyuta, pokunyorera kana mumwe mudziyo inokwanisa kushanda pamwe Wireless Links. High Frequency redhiyo mafungu zvinovakomberedza mugari kwese, kunyange zvake pamubhedha. City - rimwe "muviri" umo munhu chiito, mumwe nzira kana imwe, zvazvinoita vamwe vagari. A yakasiyana zvachose mamiriro ezvinhu kumamisha, uko kunyange chiratidzo zvitsigiro ravarwi ari Mobile opareta zvingava zvakaoma kuti "kubatwa". Saka, nyaya yedu sei inokuvadza kana Wi-Fi, achava kufarira zvikurukuru vagari kumaguta.
Kana mumwe munhu anowana ngozi illusory, ipapo zviri nyore kuona Kuwanikwa. Zviri zvakakwana kutsausa Wi-Fi module ari ake foni uye atarise rakapoteredza. Zvirokwazvo ipapo chidzitiro pasi kuwana pfungwa. Somuenzaniso, kwatiri, inowanikwa chete "mwero» Cisco S2970, asi kana Wi-Fi zvakaipa, saka zviri zvakakwanira kurwara. Sezvaunoziva, duku donhwe anokwanisa zvishoma nezvishoma kuparadza kunyange ibwe.
Sezvo zvinowanzoitwa, vakawanda vakaona masayendisiti kutsvaka mhinduro yomubvunzo wokuti Wi-Fi zvinokuvadza, hakubatsiri. Apo mazakwatira emari zvinobatanidzwa, chokwadi haisi kuwanikwa. Edza kunzwisisa pachavo uye kuti kutenda mhedziso kana kwete - a private nyaya mumwe munhu.
Wi-Fi zvemichina - ndiko chimiro chimwe Wireless kupararira digitaalinen mashoko. mudziyo mumwe nomumwe anogona kushanda mune zvose mugamuchiri wokutepfenyurisa. Kana GSM runharembozha akagadzirirwa zvikurukuru kuti inzwi pakukurukurirana, kuti Wi-Fi - nokuti kupanana binary Codes. The uchishandisa maitikiro iri basa fixedly mu mureza uye 2.4 GHz. Kunakisa yokukurukurirana Wireless kwakadaro pachena - hapana chikonzero kumhanya unobatanidza waya.
Saka zvakaipa ipapo Wi-Fi? Kuti tipindure, ngatiregei yeuka kosi kuti Physics, Chikamu pamusoro Electrical Engineering. Kunyange shure muna 1831 akakurumbira musayendisiti Michael Faraday akaziva chinhu chinonakidza chinoshamisa inonzi remagetsi induction. Anorevei nyore: Kana muitisi iyo anoumba munhu namahwindo redunhu, mumwe rakatumbuka munda kuita, wayo sekiristaro yekamuri kunoitika nomuzvarirwo (vakafurira) iyezvino. The zvakawanda munda Mitsetse vayambuke kondakita, zvikuru chaizvo vemazuva ano.
Radio mafungu - ichi ndicho chete remagetsi munda. Kunyange zvazvo parizvino achiri haagoni kupindura mubvunzo, "Ngozi kana Wi-Fi», asi zvinoita kuti tikwanise kufunga kuti matambudziko ari mumuviri womunhu (ropa, Urume - rakaisvonaka vatungamiriri) achiri iri. Kazhinji, kuongorora kunoratidza kuti Wi-Fi mudziyo simba riri kusvika 10 nguva shoma pane GSM dzeserura. Asi ichi ndicho chete chikamu chokwadi. Tarisa kombiyuta simba nerubatsiro - iduku uye chiedza. The transformer zvakafanana vachikwanisa kwaizova hombe asina kutapudza pahafu kilogram. Izvi kubudirira kuburikidza nokushandisa wavelet rokuchinja musimboti. Kana pari dererei, asi kuwedzera kakawanda, hunobvumira kuti aponese pasina kuchinja goho simba. Mhedziso: hazvina basa kuti GSM simba pamusoro. In Wi-Fi ndiye kanoverengeka yakakwirira kakawanda, izvo zvakazara compensates nokuda musiyano. Mukuwedzera, nokuwanda chiedza zvinyorwa hunokonzera kutanga rokuchengeta chipingaidzo, izvo exacerbates zvinhu.
Subject kukuvadza Wi-Fi yakakura zvokuti hazvigoni munyaya imwe chete nyaya. Data vose pachena, saka munhu wose hwokuva zvakakodzera, anogona kuaverenga.
