Kuyambira 802.11n, teknoloji ya MIMO yakhala ikugwiritsidwa ntchito mu protocol iyi ndipo yasintha kwambiri kuchuluka kwa kutumizira opanda zingwe.Makamaka, momwe mungakwaniritsire ukadaulo wapamwamba kwambiri.Tsopano tiyeni tione mwatsatanetsatane luso la MIMO.Ndi kupita patsogolo kwaukadaulo wolumikizirana opanda zingwe, mor...

Pali mitundu yambiri ya masinthidwe pamsika, koma palinso zosiyana zogwirira ntchito, ndipo mbali zazikulu ndizosiyana.Itha kugawidwa molingana ndi malingaliro otakata komanso kukula kwa ntchito: 1) Choyamba, m'lingaliro lalikulu, masiwichi amtundu amatha kugawidwa m'magulu awiri ...

Mfundo: Mfundo ya Direct Sequence Spread Spectrum system ndiyosavuta.Mwachitsanzo, zidziwitso zambiri zomwe ziyenera kutumizidwa zimakulitsidwa kukhala gulu lalikulu kwambiri kudzera pa PN code.Pamapeto olandila, zomwe zatumizidwa zimabwezedwa polumikizana ndi sipekitiramu yofalikira ndi ...

EVM: Chidule cha Error Vector Magnitude, kutanthauza kukula kwa vekitala yolakwika.Kutumiza kwa digito ma frequency band ndikusinthira siginecha ya baseband kumapeto kotumiza, kuitumiza pamzere kuti itumizidwe, kenako ndikuyitsitsa pamapeto olandila kuti abwezeretsenso choyambirira ...

Mfundo yogwira ntchito: Node iliyonse yosinthira ikalandira lamulo lotumizira deta, imasaka mwachangu patebulo la adilesi yosungidwa kukumbukira kuti itsimikizire malo olumikizirana ndi kirediti kadi ndi adilesi ya MAC ndikutumiza deta ku node.Ngati malo ogwirizana ndi ...

Ma modules osiyanasiyana amtundu wachitatu pamsika ali ndi ubwino waukulu pamtengo poyerekeza ndi ma modules oyambirira optical, omwe amatha kuthetsa bwino vuto la mtengo wapamwamba wotumizira ma modules optical.Komabe, anthu ena amadandaulabe za mtundu wa ma module optical ogwirizana.HDV...
