Monga momwe tawonetsera pamwambapa, tikhoza kumvetsetsa maonekedwe a RJ45 malinga ndi chithunzicho, koma osati mawonekedwe onse a RJ45 monga omwe ali pamwambawa ndi RJ11 interfaces, zomwe sizidzakambidwa kwakanthawi. Zosinthazi zimakonzedwa mbali ndi mbali ndi madoko angapo a RJ45, omwe ...

Nthawi zambiri, kuyanjana kwa ma module owoneka kumatanthawuza ngati ma module amatha kugwira ntchito bwino pazida zoyankhulirana zamitundu yosiyanasiyana ndi opanga. Tekinoloje zomwe zili m'ma module optical ndizochepa, ndipo mawu awo oyamba ndi osavuta. Chifukwa chake, ambiri ...

kapena chitsanzo cha OSI, kusinthaku kumagwira ntchito pagawo lachiwiri lachitsanzo ichi, chingwe cholumikizira deta. Monga tawonera pachithunzi chotsatira, kusinthaku kuli ndi madoko asanu ndi atatu. Chidacho chikalumikizidwa mu switch kudzera pa RJ45, chip master cha switchcho chimazindikira madoko omwe alumikizidwa mu netiweki...

Module ya PON ndi mtundu wa module ya kuwala. Zimagwira ntchito pazida za OLT terminal ndikulumikizana ndi zida zaofesi za ONU. Ndi gawo lofunikira pa netiweki ya PON.

FHSS, teknoloji yafupipafupi yodumphira kufalikira kwa sipekitiramu, pansi pa chikhalidwe cha kugwirizanitsa ndi nthawi imodzi, imavomereza zizindikiro zomwe zimaperekedwa ndi zonyamulira zopapatiza zamtundu winawake (mawonekedwe enieniwa ali ndi mafupipafupi, ndi zina zotero) pamapeto onse awiri. Kwa wolandila wopanda mtundu wina wake, hop...

OFDM yaperekedwa mu IEEE802.11a. Kutengera njira yosinthira iyi, tiyenera kudziwa kuti OFDM ndi chiyani kuti timvetsetse ma protocol osiyanasiyana. Kodi OFDM ndi chiyani? OFDM ndi ukadaulo wapadera wonyamula zinthu zambiri. Tekinoloje iyi ikufuna kugawa tchanelo kukhala njira zingapo za orthogonal, ndi ...
