Kodi 5G Imagwira Ntchito Motani Pansi Pansi?

5G ndi m'badwo wachisanu waukadaulo wopanda zingwe. Ogwiritsa ntchito adzadziwa kuti ndi imodzi mwamakina othamanga kwambiri, olimba kwambiri padziko lonse lapansi. Izi zikutanthauza kutsitsa mwachangu, kuchedwa kwambiri, komanso kukhudza kwambiri momwe timakhalira, ntchito, ndi kusewera.

Komabe, pansi pa nthaka, pali masitima apamtunda wapansi panthaka. Kuwonera makanema achidule pafoni yanu ndi njira yabwino yopumira panjanji yapansi panthaka. Kodi 5G imaphimba bwanji ndikugwira ntchito mobisa?

Kutengera zofunikira zomwezo, kufalikira kwa metro ya 5G ndi nkhani yofunika kwambiri kwa ogwiritsa ntchito Telecommunication.

Ndiye, 5G imagwira ntchito bwanji mobisa?

Sitima yapa Metro ndi yofanana ndi chipinda chapansi cha nsanjika zambiri, ndipo itha kuthetsedwa mosavuta ndi njira zachikhalidwe za In-building kapena makina atsopano a Distributed antenna ndi ogwira ntchito. Wogwiritsa ntchito aliyense ali ndi dongosolo lokhwima kwambiri. Chokhacho ndikutumiza momwe zidapangidwira.

Chifukwa chake, njira yayitali yapansi panthaka ndiyomwe imayang'ana kwambiri njira zapansi panthaka.

Misewu ya Metro nthawi zambiri imakhala yopitilira mamita 1,000, yotsatiridwa ndi yopapatiza komanso yopindika. Ngati mugwiritsa ntchito mlongoti wolozera, chizindikiro chodyera msipu ndi chaching'ono, kuchepetsako kumakhala kofulumira, ndipo ndikosavuta kutsekedwa.

Kuti athane ndi mavutowa, ma siginecha opanda zingwe amayenera kumasulidwa chimodzimodzi motsatira njira ya ngalandeyo kuti apange mawonekedwe amtundu wa mzere, womwe ndi wosiyana kwambiri ndi magawo atatu omwe amawululira ma macro station. Izi zimafuna mlongoti wapadera: chingwe chotayira.

Nthawi zambiri, zingwe zama radio-frequency, zomwe zimadziwika kuti feeders, zimalola kuti chizindikirocho chiziyenda mkati mwa chingwe chotsekedwa, osati kungotulutsa chizindikirocho, koma kutayika kwa kachilomboka kumatha kukhala kocheperako. Kuti chizindikirocho chisunthidwe bwino kuchokera kugawo lakutali kupita ku mlongoti, ndiye kuti mafunde a wailesi amatha kufalitsidwa bwino kudzera mu mlongoti.

Kumbali ina, chingwe chotayirira ndi chosiyana. Chingwe chotayirira sichimatetezedwa kwathunthu. Ili ndi kagawo kotayikira komwe kamagawika, ndiko kuti, chingwe chotayikira ngati mipata yaying'ono, imalola kuti chizindikirocho chituluke molingana ndi mipata.

Foni yam'manja ikalandira zizindikilo, ma siginecha amatha kutumizidwa kudzera m'mipata kupita mkati mwa chingwe kenako nkutumizidwa ku Base Station. Izi zimalola kulumikizana kwa njira ziwiri, zopangidwira mizera yamizere ngati mizere ya metro, zomwe zimafanana ndi kutembenuza mababu achikhalidwe kukhala machubu aatali a fulorosenti.

Kuphimba kwa Metro tunnel kumatha kuthetsedwa ndi zingwe zotayikira, koma pali zovuta zomwe ziyenera kuthetsedwa ndi ogwira ntchito.

Kuti athandize ogwiritsa ntchito awo, onse ogwira ntchito amayenera kuwonetsetsa ma sign a metro. Popeza malo ochepa a ngalandezi, ngati wogwiritsa ntchito aliyense akupanga zida, zitha kukhala zowononga komanso zovuta. Chifukwa chake ndikofunikira kugawana zingwe zomwe zikuchucha ndikugwiritsa ntchito chipangizo chomwe chimaphatikiza ma sipekitiramu osiyanasiyana kuchokera kwa ogwiritsa ntchito osiyanasiyana ndikutumiza ku chingwe chotayikira.

Chipangizocho, chomwe chimaphatikiza ma siginecha ndi ma spectrum kuchokera kwa ogwiritsa ntchito osiyanasiyana, chimatchedwa Point of Interface (POI) Combiner. Zophatikizira zimakhala ndi zabwino zophatikizira mazizindikiro ambiri komanso kutayika kochepa kolowetsa. Zimagwira ntchito pa njira yolumikizirana.

Pachithunzi chotsatira chikuwonetsa, chophatikizira cha POI chili ndi madoko angapo. Itha kuphatikiza mosavuta 900MHz, 1800MHz, 2100MHz, ndi 2600MHz ndi ma frequency ena.

Kuyambira 3G, MIMO adalowa mu gawo la mauthenga a m'manja, kukhala njira zofunika kwambiri zowonjezera mphamvu zamagetsi; ndi 4G, 2 * 2MIMO wakhala muyezo, 4 * 4MIMO ndi mkulu mlingo; mpaka nthawi ya 5G, 4 * 4 MIMO yakhala yokhazikika, mafoni ambiri amatha kuthandizira.

Chifukwa chake, kufalikira kwa metro tunnel kuyenera kuthandizira 4 * 4MIMO. Chifukwa cha njira iliyonse ya dongosolo la MIMO imafunikira mlongoti wodziyimira pawokha, kuphimba kwa ngalandeyo kumafunikira zingwe zinayi zofananira zotayikira kuti zikwaniritse 4 * 4MIMO.

Monga chithunzi chotsatirachi chikuwonetsera: 5G yakutali ngati gwero la chizindikiro, imatulutsa zizindikiro za 4, kuziphatikiza ndi zizindikiro za ogwira ntchito ena kudzera pa chophatikizira cha POI, ndikuzidyetsa mu zingwe za 4 zofananira zotayikira, zimakwaniritsa kulumikizana kwapawiri kwapawiri. . iyi ndiyo njira yolunjika komanso yothandiza kwambiri yowonjezera mphamvu ya machitidwe.

Chifukwa cha liwiro lalikulu la sitima yapansi panthaka, ngakhale kutayikira kwa chingwe kuphimba chiwembucho kukhala mzere, mafoni am'manja amasinthidwa pafupipafupi ndikusankhidwanso pamzere wa chiwembucho.

Kuti athetse vutoli, atha kuphatikiza madera angapo kukhala gulu lapamwamba, momveka bwino ndi gulu limodzi, motero kukulitsa kangapo kufalikira kwa gulu limodzi. Mutha kupewa kusintha ndikusankhanso nthawi zambiri, koma kuchuluka kwake kumachepetsedwa, kumakhala koyenera madera ochepera olumikizirana.

Chifukwa cha kusinthika kwa kulumikizana kwa mafoni, titha kusangalala ndi ma foni am'manja nthawi iliyonse, kulikonse, ngakhale mobisa.

M'tsogolomu, zonse zidzasinthidwa ndi 5G. Kuthamanga kwa kusintha kwaukadaulo m'zaka makumi angapo zapitazi kwakhala kofulumira. Chokhacho chomwe tikudziwa ndi chakuti, m'tsogolomu, zikhala mofulumira kwambiri. Tikhala ndi kusintha kwaukadaulo komwe kungasinthe anthu, mabizinesi, ndi anthu onse.
