3G - chizvarwa chechitatu chenharembozha chashandura nzira yatinotaurirana nayo tichishandisa nharembozha.Manetiweki e4G anokwidziridzwa aine zvirinani data data uye ruzivo rwemushandisi.5G ichakwanisa kupa mobile Broadband anosvika 10 gigabits pasekondi panguva yakaderera latency yemamilliseconds mashoma.
Ndeupi musiyano mukuru pakati pe4G ne5G?
Speed
Kana zvasvika ku5G, kumhanya ndicho chinhu chekutanga munhu wese anofara nezve tekinoroji.LTE advanced tekinoroji inokwanisa data reti kusvika ku1 GBPS pane 4G network.5G tekinoroji inotsigira data reyero kusvika ku5 kusvika ku10 GBPS panharembozha uye pamusoro pe20 GBPS panguva yekuedzwa.
5G inogona kutsigira data rakadzika zvikumbiro se4K HD multimedia kutenderera, augmented real (AR) uye chaiyo chaiyo (VR) application.Uyezve, nekushandiswa kwemamilimita mafungu, chiyero che data chinogona kuwedzerwa pamusoro pe40 GBPS uye kunyange kusvika ku100 GBPS mune ramangwana 5G network.
Millimeter mafungu ane yakakura bandwidth kana ichienzaniswa neakaderera bandwidth frequency mabhendi anoshandiswa mu4G tekinoroji.Nepamusoro bandwidth, yakakwirira chiyero che data chinogona kuwanikwa.
Kunonoka
Latency izwi rinoshandiswa mu network tekinoroji kuyera kunonoka kwemasaini mapaketi anosvika kubva kune imwe node kuenda kune imwe.Mune nharembozha, inogona kutsanangurwa senguva inotorwa nemasaini eredhiyo kufamba kubva pa base station kuenda kune nharembozha (UE) uye zvichipesana.
Latency ye4G network iri pakati pe200 kusvika 100 milliseconds.Munguva yekuedzwa kwe5G, mainjiniya akakwanisa kuita uye kuratidza yakaderera latency ye1 kusvika 3 milliseconds.Low latency yakakosha mumisheni yakawanda yakakosha maapplication uye nekudaro 5G tekinoroji yakakodzera kune yakaderera latency application.
Muenzaniso: mota dzinozvityaira, kuvhiyiwa kure, drone operation etc...
Advanced Technology
Kuti uwane ekupedzisira-nekukurumidza uye yakaderera latency masevhisi, 5G inofanirwa kushandisa yepamusoro network terminologies senge millimeter mafungu, MIMO, beamforming, mudziyo kudhizaini kutaurirana uye yakazara duplex modhi.
Wi-Fi kuburitsa zvakare imwe nzira inokurudzirwa mu5G yekuwedzera kugona kwedata uye kuderedza mutoro pazviteshi zvepasi.Midziyo yenhare inogona kubatana kune inowanika isina waya LAN uye kuita zvese mashandiro (izwi uye data) pachinzvimbo chekubatanidza kune zviteshi zvepasi.
4G uye LTE tekinoroji yepamusoro inoshandisa nzira dzemodulation seQuadrature Amplitude Modulation (QAM) uye Quadrature Phase-Shift Keying (QPSK).Kuti ukunde zvimwe zvipimo mu4G modulation schemes, yakakwirira state Amplitude Phase-Shift Keying maitiro ndeimwe yekufunga nezve 5G tekinoroji.
Network architecture
Muzvizvarwa zvekare zvenharembozha, Radio Access Networks iri padyo nechiteshi.MaRAN echinyakare akaomarara, anodiwa anodhura zvivakwa, nguva nenguva kugadzirisa uye kushomeka kwekuita.
Tekinoroji ye5G ichange ichishandisa Cloud Radio Access Network (C-RAN) kuita zvirinani.Vashandisi venetiweki vanogona kupa internet-inokurumidza kukurumidza kubva kune yepakati gore yakavakirwa redhiyo yekuwana network.
Internet yezvinhu
Internet yezvinhu nderimwe izwi guru rinowanzokurukurwa ne5G tekinoroji.5G ichabatanidza mabhiriyoni emidziyo uye smart sensors kune internet.Kusiyana ne4G tekinoroji, 5G network ichakwanisa kubata yakakura data vhoriyamu kubva kune akawanda maapplication senge smart imba, maindasitiri IoT, smart hutano, maguta akangwara nezvimwe…
Imwe huru yekushandisa ye5G muchina kune muchina mhando yekutaurirana.Mota dzinozvimirira dzichatonga migwagwa yeramangwana nerubatsiro rwe advanced low latency 5G masevhisi.
Narrow Band - Internet yezvinhu (NB - IoT) zvikumbiro senge smart lighting, smart metres, uye smart parking solutions, mepu yemamiriro ekunze ichaiswa pachishandiswa 5G network.
Ultra Reliable mhinduro
Kuenzaniswa ne4G, ramangwana 5G zvishandiso zvinopa zvinogara zvakabatana, zvekupedzisira-zvakavimbika uye zvakanyanya kushanda mhinduro.Qualcomm nguva pfupi yadarika yakaburitsa yavo 5G modem yezvishandiso zvakangwara uye makomputa emangwana emunhu.
5G ichakwanisa kubata yakakura data data kubva kumabhiriyoni emidziyo uye network inokonzeresa kukwidziridzwa.4G uye yazvino LTE network ine painogumira maererano nehuwandu hwe data, kumhanya, latency uye network scalability.5G matekinoroji achakwanisa kugadzirisa nyaya idzi uye kupa mhinduro inodhura kune vanopa masevhisi uye vashandisi vekupedzisira.
