5G ndiyo tekinoroji yechizvarwa chechishanu, inonyanya kuratidzwa nemirimita wavelength, ultra wideband, ultra-high speed, uye ultra-low latency.1G yakawana kutaurirana kwezwi reanalog, uye mukoma mukuru haana skrini uye anogona kungofona chete;2G yakawana digitization yekukurukurirana kwezwi, uye muchina unoshanda une diki skrini inogona kutumira mameseji;3G yakawana multimedia kutaurirana kupfuura izwi nemifananidzo, zvichiita kuti skrini ive yakakura yekuona mifananidzo;4G yakawana nharaunda yepamusoro-yekumhanya kweinternet, uye mahombe skrini emafoni anogona kuona mavhidhiyo mapfupi, asi chiratidzo chakanaka mumaguta uye varombo mumaruwa.1G ~ 4G inotarisa pane zviri nyore uye zvinobudirira kutaurirana pakati pevanhu, nepo 5G ichigonesa kubatana kwezvinhu zvese chero nguva, chero kupi, ichibvumira vanhu kuti vatarisire kupindirana kutora chikamu nezvinhu zvese zvePasi kuburikidza nekurarama kutenderera pasina musiyano wenguva.
Kusvika kweiyo 5G nguva uye kuunzwa kweMassive MIMO tekinoroji zvakatungamira zvakananga kune matatu maitiro mukuvandudzwa kwe5G base station antennas:
1) Kukudziridzwa kwemapassive antennas kune inoshanda antenna;
2) Fiber optic inotsiva feeder;
3) Iyo RRH (redhiyo frequency kure kure musoro) uye antenna zvakabatanidzwa zvishoma.
Nekuenderera mberi kwekushanduka kwemanetiweki ekutaurirana akananga ku5G, ratidza antenna (yakawanda antenna space division multiplexing), akawanda danda antenna (network densification), uye akawanda bhendi antenna (spectrum kuwedzera) anozova iwo makuru emhando dzebase station antenna kusimudzira mune ramangwana.
Nekusvika kwe5G network, zvinodikanwa zvevashandisi vakuru venharembozha zviri kuramba zvichichinja.Kuti uwane kuvharika kwakazara kwenetiweki, akawanda uye akawanda marudzi e base station tuning antennas anoshandiswa zvakanyanya mumunda wekutaurirana mbozha.Kune ina mafrequency antenna, kuitira kuti iwane kutonga kweayo emagetsi kudzika pasi tilt angle, parizvino kune matatu makuru marudzi emagetsi ekugadzirisa ekugadzirisa maturusi, anosanganisira musanganiswa weaviri akavakirwa-mukati maviri emagetsi emagetsi ekugadzirisa ma controller, maviri emagetsi emagetsi ekugadzirisa controller. ine transmission switching mechanism, uye ina yakavakirwa-mukati mota magetsi ekugadzirisa controller.Zvinogona kuoneka kuti zvisinei kuti ndeupi mudziyo unoshandiswa, haugone kuparadzaniswa nekushandiswa kweantenna motors.
Chimiro chikuru cheiyo base station yemagetsi tuning antenna mota imota inodzikisira yakabatanidzwa muchina wakagadzirwa nemota yekutapurirana uye yekudzikisa giya bhokisi, ine deceleration gadziriso basa;Iyo mota yekufambisa inopa inobuda nekumhanya uye yakaderera torque kumhanya, uye giya bhokisi rakabatana nemota yekutapurirana kuti ideredze kubuda kwemota yekutapurirana ichiwedzera torque, kuwana yakanakira kutapurirana maitiro;Iyo base station yemagetsi tuning antenna mota giya bhokisi rinowanzo tora yakagadziridzwa mota giya bhokisi tekinoroji paramita, simba, uye kuita kuti isangane zvirinani nemamiriro ekunze senge nharaunda, mamiriro ekunze, mutsauko wekushisa, uye kuwana yakanakira kutapurirana maitiro uye sevhisi zvinodiwa zvehupenyu.
