Zonse zomwe mukufuna kudziwa za LAN opanda waya
WiFi (yomwe inalembedwanso Wi-Fi) imayimira kukhulupirika kosayendetsedwa. Ndi makina opangidwa ndi mafoni opanda waya omwe amalola makompyuta ndi zipangizo zina kuti zigwirizane wina ndi mnzake ku LAN komanso ku intaneti popanda waya ndi zingwe. WiFi imatchedwanso WLAN, yomwe imayimira LAN opanda waya, ndi 802.11, yomwe ndi chikhalidwe cha ma protocol.

WiFi Worth and Limitations
WiFi imapereka mphamvu zowonongolerana ndipo yasintha LAN padziko lonse. Chifukwa cha WiFi, anthu ambiri amatha kugwirizana ndi intaneti komanso mosavuta. Phindu lalikulu la WiFi ndilo lingaliro limene limapereka kwa anthu ogwiritsa ntchito makompyuta apakompyuta ndi zipangizo zamanja monga mafoni a m'manja ndi PDAs - akhoza kusintha kuchokera pa intaneti kupita ku wina popanda vuto lodandaula za waya.
WiFi imakhala yochepa kwambiri, ndipo ndiyo yokha yochepa yomwe ili nayo. Popeza ndi luso lamakono, WiFi imapereka malo oyanjana ndi mapazi ena okha. Pambuyo pa mamita 20-25, inu muli chabe kunja kwa intaneti. Mng'oma ya WiFi imatumiza mafunde ponseponse pozungulira. Zizindikiro za WiFi zimataya kwambiri pamene zimachoka kutali ndi antenna, chifukwa chake khalidwe la mgwirizano limachepa pamene kompyuta kapena chipangizo chimayikidwa kutali kwambiri ndi gwero. Kugwiritsa ntchito mauthenga a WiFi pa makompyuta ndi zipangizo zina nthawi zambiri zimakhala ndi miyeso yolemba mphamvu zogwirizana: zabwino, zabwino, osauka.
WiFi Hotspots
Malo otsekemera a WiFi ndi malo omwe ali pafupi ndi WiFi (galimoto yopanda waya, ma WiFi antenna, ndi zina zotero, kupanga zizindikiro za WiFi) zomwe makompyuta ndi zipangizo zingagwirizane kudzera mu WiFi. Hotspots amapezeka m'malo ambiri: pamasukulu, m'maofesi, m'mabhawa, ngakhale panyumba. Mwachitsanzo, mungathe kukhala ndi WiFi hotspot panyumba mwa kukhala ndi router opanda waya ndi mzere wanu wautali. The router imatumiza WiFi mnyumba mwako ndipo makompyuta anu ndi zipangizo zingagwirizane popanda waya. Werengani zambiri pa malo ozizira a WiFi .
Mapulogalamu a WiFi - 802.11
WiFi kwenikweni ndi protocol , yomwe, m'mawu awiri, ndi malamulo omwe amachititsa kuti magetsi azigwiritsidwa ntchito pa intaneti, kuti atenge makina onse ogwirizana. Dzina ladipatimenti yoperekedwa ndi IEEE ku banja la machitidwe omwe WiFi imapezeka ndi 802.11. Nambalayi nthawi zambiri imatsatiridwa ndi kalata: a, b ndi g ndi WiFi. 802.11g ndiyatsopano ndi yabwino kwambiri, yomwe ili ndi liwiro lapadera lofalitsira mauthenga ndi maulendo ambiri.
Zimene Mukufunikira pa WiFi
Simusowa zambiri kuti mutha kupindula ndi WiFi. Ndikofunika kwambiri kukhazikitsa intaneti, osati kuti ndi zovuta, koma hardware idzawonongetsa pang'ono. Koma sizinanditengere kanthu kuti ndikhale ndi WiFi yanga yokhala pakhomo pakhomo, chifukwa ndili ndi router yanga yopanda mauthenga ndi webusaiti yanga yamtundu wa intaneti.
Tsopano zomwe mukusowa ndi makompyuta ndi zipangizo zomwe zilipo WiFi. Pankhani ya makompyuta ndi laptops, amafunika kukhala ndi adapita kapena makadi a WiFi. Mukamagula laputopu, onetsetsani kuti mukuwona WiFi kapena WLAN kapena 802.11g pazinthu zomwe mukufuna. Ngati laputopu yanu ilibe, mungathebe kukhala ndi adapala ya USB Wi-Fi. Zomwe zimagwiranso ntchito pa kompyuta yanu. Kwa mafoni a m'manja, amayenera kuthandizira mafoni a WiFi ndi mafoni a WiFi ndi ochepa komanso odula, ngakhale atakhala otchuka kwambiri.
Ndiye mufunika mapulogalamu. Koma izi sizowonongeka, chifukwa mafoni a WiFi amabwera ndi chithandizo cha pulogalamuyo ndi machitidwe onse otchuka opangira makompyuta amabwera ndi pulogalamu yamakono yogwiritsira ntchito WiFi. Palinso pulogalamu yaulere pulogalamu yowunikira, ngati mukufuna chipangizo chapakati pazomwe mukuyang'anira ma WiFi.
Kodi WiFi Ingakupindulitseni Bwanji?
WiFi ikhoza kukuthandizani m'njira zambiri:
- Amapereka mwayi. Ndimagwiritsa ntchito intaneti mosavuta komanso mosasunthika pakompyuta yanga pakompyuta kunyumba ndi kuntchito. Izi ndichifukwa chakuti ndimakhala ndi ma WiPi hotspots onse kunyumba ndi kuntchito. Ndikhoza kulumikizidwa mwanjira ina kulikonse komwe kuli WiFi hotspot, monga mu munda wa municipalities, mwachitsanzo.
- Ndi njira yabwino kwambiri yolumikizira intaneti ndi mafoni apamwamba komanso PDAs. Izi zimatsegula mwayi wambiri wogwiritsa ntchito mafoni, kuphatikizapo kufufuza pa intaneti, kusewera masewera, kulankhulana, ndi zina zotero.
- Zimapangitsa kuti LAN zikhale zosasintha, zowonongeka komanso zamphamvu. Makina aliwonse akhoza kugwirizana ndi kutaya mu intaneti nthawi iliyonse.
- Amaloleza malo omwe ali kutali ndipo motero amalephera kugwiritsa ntchito zipangizo zoyankhulirana, monga m'madera akumidzi m'mayiko akutukuka, kuti apindule ndi kulumikizana. Zowonjezera zina zimafunikira ndi okonza, koma izi ndizotheka kumadera ambiri: mwachitsanzo onani inveneo.com, airjaldi.com, wndw.net
- Zimakupatsani inu kusunga ndalama zochuluka pa kuyankhulana kupyolera mu chipangizo chanu panthawi yopanga maitanidwe am'deralo ndi apadziko lonse, kupyolera mu VoIP. Werengani m'munsimu.
WiFi ndi Voice over IP - Kusunga Ndalama pa Kulankhulana
Voice over IP , kuphatikizapo ubwino wake ambiri, amalola anthu kulankhulana kudzera mau kwa otchipa kwambiri ngati siufulu. Pogwiritsa ntchito VoIP ndi makompyuta anu apakompyuta kapena chipangizo mu WiFi hotspot, mukhoza kupanga maulendo aufulu kapena otchipa.
