Iko kushanduka kwe5G tekinoroji: kubva pasi-frequency mabhendi kuenda kuC-band bandwidth

Sezvo nyika yakamirira nemoyo wese kuzadzikiswa kwakapararira kwehunyanzvi hwe5G, kuomarara kwemabhendi ayo akasiyana-siyana uye mabatiro ayo pakuita kwetiweki kuri kuwedzera kujekeswa. Shanduko kubva ku4G LTE kuenda ku5G inounza nhevedzano yebudiriro yetekinoroji nematambudziko, kubva mukuderedza kupindira kune leveraging fiber optic zvivakwa uye mukana wekuwedzera network kumhanya.
Lower frequency 5G mabhendi, akadai seye 600MHz bvunzo, akafanana mukuita ku4G LTE, aine bvunzo dzakadai sePIM uye scanning inoratidza maitiro akafanana. Nekudaro, mutsauko wakakura uri muzvivakwa, sezvo kuisirwa kwe5G kunovimba nefiber optic zvivakwa kwete coaxial tambo. Uku kushanduka kwezvivakwa kunoreva shanduko yakakosha kune yakadzika tekinoroji inotsigira 5G network, ichigadzira nzira yekusimudzira kushanda nekuita.
Sezvo ma frequency mabhendi anosvika 3-3.5GHz uye nekupfuura, matekinoroji akadai sebeamforming uye millimeter wave anotora nzvimbo yepakati, achiratidza kukosha kwawo mukugadzira ramangwana re5G. Beamforming inzira yekugadzira masaini inoshandisa akawanda antenna akapihwa neMassive MIMO kugadzira chiratidzo chakamisikidzwa pakati peantenna uye chaiyo mushandisi mudziyo, ine mukana wekudzikisa kupindira uye kuwedzera chiratidzo chekuvhara. Iyi tekinoroji, yakasanganiswa nekushandiswa kwemasaisai emamirimita, inomiririra kusvetukira kukuru mukutsvaga kusina musono, kunoshanda kwe5G yekubatanidza.
Kubuda kwe5G standalone (SA) network kwaunza shanduko yeparadigm mukugadzirisa dambudziko rekupindira. Nepo nharaunda dze4G LTE dzichibata nekukanganisika kubva kumidziyo inowanzo shandiswa inoshanda pamhepo yakafanana nenharembozha, 5G SA network inotora mukana wemabhendi asingagarwe nemidziyo iyi, ichideredza zvakanyanya kukanganisa. Pamusoro pezvo, kubatanidzwa kweiyo beamforming tekinoroji mu5G network inogonesa vashandisi kunzvenga mamwe marudzi ekuvhiringidza, vachiratidza mukana wekusimudzira kuvimbika kwetiweki uye kuita.
Chimwe chezvinhu zvakakosha zvinokanganisa kukurumidza uye kugona kwe5G network iC-band bandwidth, iyo inowanzopa yakakura bandwidths ye50MHz kusvika 100MHz. Iyi yakawedzera bandwidth inovimbisa kuderedza mu-bhendi kusangana uye kuwedzera zvakanyanya kumhanya kwenetiweki, kukosha kwakakosha munguva iyo rinenge basa rese rinoitwa paInternet. Kukanganisa kweiyi bandwidth yakakwidziridzwa kunosvika kune akasiyana maapplication, kusanganisira augmented real, uko kumhanya kwakakosha kuunza isina musono uye inonyudza mushandisi ruzivo.
Muchidimbu, shanduko ye5G tekinoroji kubva kuzasi frequency mabhendi kuenda kuC-band bandwidth inomiririra nguva yakakosha mukuvandudzwa kwenharembozha. Iko kusanganiswa kwetekinoroji senge beamforming, millimeter wave uye kushandiswa kwefiber optic zvivakwa kunoratidza mukana wekushandura we5G network. Sezvo nyika inogadzirira kugamuchirwa kwakapararira kwe5G, vimbiso yekuwedzera kumhanya, kuderedzwa kupindira uye yakawedzera bandwidth inosheedzera nguva itsva yekubatanidza uye hunyanzvi.
