Pali kale zolemba zambiri zapamwamba za HabrΓ© zofotokozera mwatsatanetsatane momwe Wi-Fi imagwirira ntchito komanso momwe mungasinthire. Komabe, zolemba zonsezi zili ndi zolakwika zingapo zomwe zimawalepheretsa kuperekedwa monga chitsogozo cha zochita kwa mnansi wokhazikika m'nyumba yokwera kapena kupachika chosindikizira pakhoma pakhomo:
1. Popanda maphunziro a uinjiniya pang'ono, ndizovuta kumvetsetsa ndikugwiritsa ntchito zambiri mwazochita
2. zolembazo zili ndi "malembo ochuluka" kwa munthu yemwe alibe chidwi chochita chilichonse kuti akhale ndi chidwi chowerenga kuchuluka kwa malembawo.
2.1. Anthu alibe chilimbikitso chifukwa zomwe zilipo ndi: "bwanji kuchita chilichonse ngati zonse zikugwira ntchito kale"
2.2. ambiri ali otsimikiza kuti "iyenera kugwira ntchito yokha" m'njira yakuti "Ndinagula ndikuyilumikiza mumagetsi"
2.3. anthu saganiza ngakhale kuti Wi-Fi ikhoza kugwira ntchito bwino, amangoona mopepuka chifukwa nthawi zambiri ngakhale zida zawo zimachokera kwa wothandizira.
3. Mfundo zina m'nkhani zomwe zilipo sizinatchulidwe nkomwe kapena sizinatchulidwe mokwanira, mwachitsanzo, malingaliro omveka bwino pa malo omwe ali ndi zida sanaperekedwe.
3.1. "Kuthengo" zida za anthu zitha kuyikidwa pansi ndi tinyanga mu "maluwa" kapena ngakhale kugona pakona.
4. posankha ma tchanelo mumtundu wa 2.4 GHz, malingaliro amaperekedwa omwe ali ofunikira ku North America kokha ndipo sali abwino padziko lonse lapansi.
5. Olemba zolembazo, chifukwa cha kusokonezeka kwamaganizidwe a akatswiri, monga akatswiri aliwonse, ali ndi chinyengo chakuti ogwiritsa ntchito kunyumba adzagwiritsa ntchito njira zothetsera mavuto, mwachitsanzo, njira za 20 MHz zokha.
5.1. ndithudi iwo sadzatero, chifukwa ngakhale iwo amene anayesa kusintha chinachake mu zoikamo kuona kuti pa 40 MHz ikuwonetsa liwiro lokwera kwambiri
5.2. pazida zambiri, makamaka mu gawo la bajeti, zonse ndizoyipa kwambiri ndi makonzedwe, mutha kusankha tchanelo, nthawi zina 20/40 mode ndipo, nthawi zambiri, izi ndizomwe zilipo.
Memo imapereka malingaliro pakukhathamiritsa mawonekedwe a zida ndikusintha momwe ma antennas alili. Pochita izi, izi ndizofunikira kwambiri chifukwa malo ochepa amafunikira kuzungulira mlongoti kuti agwire ntchito. Malangizo amaperekedwanso pakufunika kokhazikitsa maziko olondola a zosokoneza.
Monga upangiri wosankha mayendedwe, memo imagwiritsa ntchito kumadera ena kupatula ku North America, mwachitsanzo, mayendedwe 1/5/9/13.

Makanema mu OFDM (802.11 a,g,n,ac) samangokhala 20 MHz, osati 22 MHz ngati DSSS (802.11 b), komanso amakhala ndi zonyamula alonda (zero) m'mphepete, kotero kugwiritsa ntchito uku ndikoyenera kwambiri chifukwa amalola kugwiritsa ntchito mayendedwe anayi a 20 MHz m'malo mwa atatu mu gulu la 2.4 GHz kapena mayendedwe awiri a 40 MHz m'malo mwa imodzi. Mu njira ya 20 MHz OFDM, mwa ma subcarriers 64, 8 akunja (4 mbali iliyonse) sagwiritsidwa ntchito potumiza deta, ndipo mphamvu zawo zimakhala ziro. Kwa njira ya 40 MHz, 128 mwa 8 sagwiritsidwanso ntchito. M'lifupi mwake chonyamulira chimodzi cha 802.11 g/n/ac ndi 312.5 kHz.
Zindikirani: mayendedwe okhala ndi 40 MHz m'lifupi: "Channel 3" ndi "Channel 11" pazithunzi zapamlengalenga ndi njira ziwiri za 20 MHz momwe chidziwitso chautumiki chimangoperekedwa panjira yayikulu yokha. Kuti mugwire bwino ntchito komanso kusamvana pakati pa maukonde, ndikofunikira kuti maukonde onse a 40 MHz azigwira ntchito ndi njira zazikulu ndi zowonjezera. Popeza zida zambiri zimakupatsani mwayi wokonza njira yayikulu yokha, mukamagwiritsa ntchito mayendedwe 40 MHz pa ma routers onse, muyenera kusankha mayendedwe 1 ndi 13 okha; kusankha njira zina, zonse 40 MHz ndi 20 MHz, zitha. kumabweretsa mikangano komanso kusachita bwino pamanetiweki kwa aliyense!
Kuphatikiza apo, pankhani yozimitsa zida zosagwiritsidwa ntchito, chitsanzo chimaperekedwa ndi rauta ya MGTS, yomwe ambiri sagwiritsidwa ntchito pa intaneti (telefoni ya waya yokha imagwiritsidwa ntchito), ndipo nthawi zambiri amayikidwa mokakamiza. Chifukwa chake Wi-Fi m'ma router awa nthawi zonse imakhala yopanda ntchito ndipo imangowulutsa ma beacons ka 10 pamphindikati.
Zolemba zomwe zilipo za HabrΓ©
Mwina sindinaphatikizepo maulalo osangalatsa apa, chonde onjezani mu ndemanga.
Kawirikawiri, ndikuyembekeza ndemanga ndi zowonjezera. Sindikufuna kukulitsa kukula kwa memo, ndipo palibe poti ndichitire. ziyenera kuwonjezeredwa kapena china chake chosafunika chichotsedwe, ndiye onetsetsani kuti mwalemba.
Zowonjezera 20.07.10: Memo yasinthidwa (zolembazo zatsukidwa pang'ono). Memo wakhalapo kwa nthawi ndithu. Sindinazitumize pa Habr ndendende chifukwa chomwe omvera akuwonetsetsa kuti alibe ma memo apa. Ndinaika memo, osati nkhani, chifukwa cha kutsutsa kolimbikitsa. Kwenikweni kutsutsa kolimbikitsa , Kuyamikira , tsopano ndikulembanso pang'onopang'ono chikalatacho ndikuwoneka mwatsopano. Pambuyo pa zosintha zonse, chikalatacho chidzayikidwa pa Pikabu ndi JoyReactor chifukwa ndipamene omvera ake, mwachitsanzo, ogwiritsa ntchito intaneti.
