Patova nezvakawanda zvemhando yepamusoro zvinyorwa paHabrΓ© zvine tsananguro yakadzama yemashandisirwo eWi-Fi uye magadzirirwo ayo. Nekudaro, zvese izvi zvinyorwa zvine kanenge kakati wandei zvikanganiso zvinovadzivirira kubva kupihwa segwara rekuita kune ane zvimiso muvakidzani muchivakwa chepamusoro-soro kana kurembera chakadhindwa pamadziro pamusuwo:
1. Pasina kana zvishoma zvidzidzo zveinjiniya, zvakaoma kunzwisisa uye kushandisa zvakawanda zvezvinhu mukuita
2. zvinyorwa zvine "mavara akawandisa" kune munhu asingakurudzirwe kuita chero chinhu kuti afarire kuverenga kuburikidza nevhoriyamu yezvinyorwa.
2.1. Vanhu vanoshaya kukurudzira nekuti mamiriro aripo ndeekuti: "nei kuita chero chinhu kana zvese zvave kushanda"
2.2. ruzhinji rune chokwadi chekuti "inofanirwa kushanda yega" muchimiro "Ndakaitenga ndikaipinza mumagetsi"
2.3. vanhu havatombofungi kuti Wi-Fi inogona kushanda zvirinani, vanongoitora sechinhu chisina basa nekuti kazhinji nyangwe midziyo yavo inobva kune mupi.
3. mamwe mapoinzi muzvinyorwa zviripo haana kutaurwa zvachose kana kuti haana kutsanangurwa zvakakwana, semuenzaniso, kurudziro yakajeka pamusoro penzvimbo chaiyo yemidziyo haina kupihwa.
3.1. "musango" midziyo yevanhu inogona kuiswa pasi neine antenna mu "bouquet" kana kunyange yakarara mukona.
4. yekusarudza zviteshi muchikamu che2.4 GHz, kurudziro inopihwa inoenderana neNorth America chete uye isina kukwana pasirese.
5. Vanyori vezvinyorwa, nekuda kwekukanganisa kwehunyanzvi hwekuona, senge chero nyanzvi, vane fungidziro yekuti vashandisi vepamba vachashandisa mhinduro dzakakwana, semuenzaniso, chete 20 MHz nzira.
5.1. chokwadi havazoiti, nokuti kunyange avo vakaedza kuchinja chimwe chinhu muzvirongwa vanoona kuti pa40 MHz inoratidza kumhanya zvakanyanya
5.2. muhuwandu hwakawanda hwemidziyo, kunyanya muchikamu chebhajeti, zvese zvakanyanya kushata nezvirongwa, unogona kusarudza chiteshi, dzimwe nguva 20/40 modhi uye, kazhinji, aya ese anowanikwa marongero.
Iyo memo inopa kurudziro yekugonesa kurongeka kwemuviri kwemidziyo uye kunyatsogadzirisa chinzvimbo cheantennas. Mukuita, izvi zvakakosha zvakanyanya sezvo hushoma huwandu hwenzvimbo hunodiwa kutenderedza antenna kuti ishande. Zvinorudziro zvinopihwawo pamusoro pekudiwa kwekudzika kwakaringana kwekukanganisa masosi.
Sekurudziro yekusarudza chiteshi, memo inoshandisa kumatunhu asiri North America, i.e. chiteshi 1/5/9/13.

Zviteshi zviri muOFDM (802.11 a,g,n,ac) hazvingotore 20 MHz chete, uye kwete 22 MHz seDSSS (802.11 b), asi zvakare ine magadhi (zero) anotakura kumicheto, saka kushandiswa uku ndiko kwakanyanya kunaka nekuti inobvumira kushandisa mana 20 MHz chiteshi panzvimbo yevatatu mu2.4 GHz bhendi kana maviri 40 MHz chiteshi pachinzvimbo cheimwe. Mune 20 MHz OFDM chiteshi, kunze kwe64 subcarriers, yekunze 8 (4 padivi rega rega) haishandiswe kutapurirana data, uye simba ravo rinosvika zero. Kune 40 MHz chiteshi, 128 kubva pa8 haichashandiswi.Pano pamufananidzo, nzvimbo chena (kwete pink) ndiyo inodzivirira subcarriers muchiratidzo. Hupamhi hweimwe subcarrier ye802.11 g/n/ac i312.5 kHz.
Cherechedza: zviteshi zvine hupamhi hwe40 MHz: "Channel 3" uye "Channel 11" mudhiyagiramu yepamhepo inzira mbiri 20 MHz umo ruzivo rwesevhisi runotumirwa chete mugero guru. Nekuita kwakaringana kushanda uye kusavapo kwekupokana pakati pemanetiweki, zvinodikanwa kuti ese 40 MHz network ashande neayo makuru uye ekuwedzera chiteshi. Sezvo ruzhinji rwemidziyo ichikubvumidza kuti ugadzirise zvakajeka chete chiteshi chikuru, kana uchishandisa 40 MHz chiteshi kune ese ma routers, iwe unofanirwa kusarudza chete chiteshi 1 uye 13 muzvirongwa; kusarudza mamwe chiteshi, ese 40 MHz uye 20 MHz, ichaita. tungamira kumakakatanwa uye kushomeka kwetiweki kuita kune wese munhu!
Sekuwedzera, mumamiriro ekudzima midziyo isina kushandiswa, muenzaniso unopiwa neMGTS router, iyo yakawanda isingashandisi kuInternet (chete foni yakashandiswa inoshandiswa), uye yaiwanzoiswa nechisimba. Saka Wi-Fi mune idzi ma routers inenge isina basa uye inongotepfenyura mabhekoni kagumi pasekondi.
Zvinyorwa zviripo paHabrΓ©
Ndinogona kunge ndisina kusanganisa ese anonakidza zvinongedzo pano, ndapota wedzera iwo mumashoko.
Kazhinji, ndinovimba kune zvirevo uye kuwedzera. Handidi kuwedzera saizi yememo zvakanyanya, uye hapana kwekuzviita. Zvakadaro, ndinovimba ndichapfuura neinenge iripo pepa reA4 mativi ese uye pepa rimwechete rekuwedzera, asi kana chimwe chinhu chakakosha. inoda kuwedzerwa kana chimwe chinhu chisingadikanwi chinofanira kudzimwa, wobva waita chokwadi chekunyora.
Kuwedzera 20.07.10: Memo yakagadziridzwa (zvinyorwa zvakacheneswa zvishoma). Memo yave iripo kwenguva yakati rebei. Ini handina kuitumira paHabr chaizvo nechikonzero chekuti vateereri vakanangwa zvakajeka havana memos pano. Ndakaisa memo, kwete chinyorwa, nekuda kwekutsoropodza kunovaka. Kushora kunovaka chaiko , Kuonga , ikozvino ndiri kunyorazve gwaro racho zvishoma nezvishoma nechitarisiko chitsva. Mushure mekugadziridzwa kwese, gwaro rinozoiswa paPikabu neJoyReactor nekuti ndipo parinotariswa vateereri, kureva vashandisi venetiweki.
