3G - network yefoni yechizvarwa chechitatu yakachinja nzira yatinotaura nayo tichishandisa nharembozha. Network dze4G dzakavandudzwa nekuwedzera kwedata uye ruzivo rwevashandisi zviri nani. 5G inokwanisa kupa nharembozha kusvika kumagigabits gumi pasekondi paine latency yakaderera yemamirisekonzi mashoma.
Ndeupi musiyano mukuru uripo pakati pe4G ne5G?
Kumhanya
Kana tichitaura nezve 5G, kumhanya ndicho chinhu chekutanga chinofarirwa nemunhu wese ne tekinoroji iyi. Tekinoroji yepamusoro yeLTE inokwanisa kuyera data kusvika pa 1 GBPS pamanetiweki e4G. Tekinoroji ye5G inotsigira data kusvika pa 5 kusvika 10 GBPS pamafoni uye pamusoro pe 20 GBPS panguva yekuyedzwa.
5G inogona kutsigira maapplication ane data rakawanda akadai se4K HD multimedia streaming, augmented reality (AR) uye virtual reality (VR). Uyezve, nekushandisa ma millimeter waves, data rate inogona kuwedzerwa pamusoro pe40 GBPS uye kunyange kusvika ku100 GBPS mune ramangwana re5G networks.
Mafungu emamiriyoni ane bandwidth yakakura zvikuru kana tichienzanisa nemabhendi ebandwidth akaderera anoshandiswa mumatekinoroji e4G. Nebandwidth yakakwira, huwandu hwedata hunogona kuwanikwa.
Kunonoka
Latency izwi rinoshandiswa mu tekinoroji yenetwork kuyera kunonoka kwemapaketi esignal kusvika kubva pane imwe node kuenda kune imwe. Muma network enharembozha, inogona kutsanangurwa senguva inotorwa nemasaini eredhiyo kufamba kubva pachiteshi chepasi kuenda kumidziyo yenharembozha (UE) uye zvinopesana.
Kunonoka kwenetwork ye4G kuri pakati pe200 kusvika 100 milliseconds. Munguva yekuyedzwa kwe5G, mainjiniya vakakwanisa kuwana uye kuratidza kunonoka kwakaderera kwe1 kusvika 3 milliseconds. Kunonoka kwakaderera kwakakosha zvikuru mumabasa mazhinji akakosha uye saka tekinoroji ye5G yakakodzera kune mapurogiramu ekudzikira kwakaderera.

Tekinoroji Yepamusoro
Kuti 5G iwane masevhisi ekukurumidza uye ekudzikira kwekukurumidza, inofanira kushandisa mazwi epamusoro enetwork akadai se millimeter waves, MIMO, beamforming, kutaurirana kwemudziyo kubva kune mumwe nemumwe uye full duplex mode.
Kubvisa Wi-Fi inzira imwe inokurudzirwa mu5G yekuwedzera kushanda zvakanaka kwedata uye kuderedza mutoro pazviteshi zvepasi. Zvishandiso zvefoni zvinogona kubatana neLAN isina waya iripo uye kuita mabasa ese (izwi nedata) pachinzvimbo chekubatanidza kuzviteshi zvepasi.
Tekinoroji yepamusoro ye4G neLTE inoshandisa matekiniki ekushandura modulation akadai seQuadrature Amplitude Modulation (QAM) uye Quadrature Phase-Shift Keying (QPSK). Kuti ikunde zvimwe zvezvipingamupinyi muzvirongwa zvekushandura 4G, nzira yepamusoro yeAmplitude Phase-Shift Keying ndeimwe yenzira dzinoshandiswa pakuongorora tekinoroji ye5G.
Magadzirirwo enetwork
Muzvizvarwa zvekare zvema network enharembozha, Radio Access Networks dziri pedyo nechiteshi chepasi. MaRAN echinyakare akaomarara, anoda zvivakwa zvinodhura, kugadziriswa nguva nenguva uye kushanda zvakanaka kushoma.
Tekinoroji ye5G ichashandisa Cloud Radio Access Network (C-RAN) kuti ishande zvakanaka. Vashandisi venetwork vanogona kupa internet inokurumidza zvikuru kubva kune network yeredhiyo inowanikwa mucloud.
Indaneti yezvinhu
Internet of Things ishoko guru rinowanzo kurukurwa ne 5G technology. 5G ichabatanidza mabhiriyoni emidziyo nema smart sensors ku internet. Kusiyana ne 4G technology, 5G network inokwanisa kubata data rakawanda kubva kuma applications akawanda akadai se smart home, industrial IoT, smart healthcare, smart cities etc…
Imwe nzira huru ye5G ndeyekutaurirana pakati pemuchina nemuchina. Mota dzinozvitonga dzichatonga migwagwa yeramangwana nerubatsiro rwemasevhisi e5G epamusoro-soro.
Mashandisirwo eNarrow Band – Internet of Things (NB – IoT) akadai semagetsi akangwara, mita dzakangwara, uye mhinduro dzekupaka dzakangwara, mepu yemamiriro ekunze ichashandiswa uchishandisa network ye5G.
Mhinduro Dzakavimbika dzeUltra
Zvichienzaniswa ne4G, nharembozha dze5G dzemangwana dzichapa mhinduro dzakabatana, dzakavimbika zvikuru uye dzinoshanda zvakanaka. Qualcomm ichangobva kuburitsa modem yavo ye5G yenharembozha uye makombiyuta emangwana.
5G ichakwanisa kubata huwandu hwakawanda hwedata kubva kumabhiriyoni emidziyo uye network inogona kuwedzerwa kuti ivandudzwe. 4G neLTE network dziripo dzine muganho panyaya yehuwandu hwedata, kumhanya, kunonoka uye kugona kufambisa network. 5G matekinoroji achakwanisa kugadzirisa matambudziko aya uye kupa mhinduro dzinodhura kune vanopa masevhisi nevashandisi vekupedzisira.
