Kugadzira Network ye5G
Pendauluan
Munguva ino yedhijitari, kudiwa kwema network anokurumidza uye akavimbika kuri kuwedzera. Tekinoroji ye network yechizvarwa chechishanu, kana kuti 5G, inopa mhinduro kune izvi zvinodiwa. Nekumhanya kwakanyanya, kunonoka kwakaderera, uye kugona kukuru kupfuura kwakatangira (4G LTE), 5G inovhura mukana wezvinhu zvitsva zvakasiyana-siyana uye kuvandudzwa kwetekinoroji yedhijitari muzvikamu zvakasiyana-siyana. Chinyorwa chino chichaongorora zvizere magadzirirwo e network ye5G, kubva kuzvikamu zvayo zvekutanga uye misimboti yekushanda kusvika pakukanganisa kwayo pa ecosystem yedhijitari.
Zvikamu Zvikuru zve5G Network Architecture
1. Nhepfenyuro yeRedhiyo (RAN)
Radio Access Network (RAN) chikamu chakakosha chehurongwa hwe5G network, ichibatanidza michina yevashandisi (UE) kune network huru. Mu5G, RAN yakavandudzwa zvakanyanya mune tekinoroji uye mashandiro.
– Masero Madiki: Muhurongwa hwe5G, kushandiswa kwemasero madiki kwakanyatsogadzirwa. Masero madiki inzvimbo dzine simba shoma dzinofukidza nzvimbo diki zvichienzaniswa nemasero madiki. Kuisa masero madiki kunogona kuwedzera kugona kwenetwork nekushanda zvakanaka.
– Massive MIMO: Tekinoroji yeMassive Multiple Input Multiple Output (MIMO) inobvumira kushandiswa kwemaantenna akawanda pazviteshi zvebase nemidziyo yevashandisi. Izvi zvinowedzera kugona kwenetwork uye kushanda zvakanaka kwespectrum, pamwe nekuvandudza kunaka kwemasaini.
– Kugadzira Beamforming: Iyi inzira yekutumira data inotungamira masaini kunzvimbo chaiyo yemushandisi waanoda kushandisa. Izvi zvinowedzera kushanda zvakanaka kwespectrum uye zvinoderedza kupindirana pakati pevashandisi.
2. Network Yepakati (CN)
Core Network (CN) mu 5G architecture inozivikanwa zviri nani se 5G Core (5GC). CN ndiyo musimboti we network, ichitarisira data uye connections dzevashandisi mu network yese. Kana ichienzaniswa ne 4G networks, 5GC inounza zvinhu zvitsva zvakawanda.
– Basa reMushandisi weNdege (UPF): Kupatsanurwa kwemabasa ekudzora nedata muma network e5G kunounza UPF, iyo inotarisira nzira yedata remushandisi. Izvi zvinoita kuti kugoverwa kwedata kubudirire zvichienderana nezvinodiwa ne network.
- Kucheka Network: Iyi tekinoroji inobvumira network imwe chete chaiyo kuti ikakamurwa kuita ma network akawanda akagadzirirwa zvinodiwa nevashandisi kana masevhisi chaiwo. Semuenzaniso, masevhisi ekurapa angada kubatana kwakavimbika uye nekukurumidza kupfuura kubhurawuza pawebhu.
– Kugadzira Mashandiro Akavakirwa Pabasa (SBA): Zvichibva pakugadzira basa, SBA inogonesa kudyidzana pakati pezvikamu zve network kuburikidza nemaAPI (Application Programming Interfaces), zvichiita kuti system ive inochinjika uye inochinjika.
3. Network yekufambisa (TN)
Transport Network (TN) mune network ye5G inobatanidza zvimwe zvinhu zve network, zvakaita seRAN neCN. 5G inoda bandwidth yakakwira uye latency yakaderera inoda TN yakavimbika ine mashandiro akanaka.
– Synchronous Ethernet (SyncE): Iyi tekinoroji inoshandiswa kuona kuti nguva inopindirana zvakanaka pazvinhu zvese zve network.
– Optical Transport Network (OTN): Kushandiswa kweOTN kunoita kuti pave nekukwanisa kukuru uye kushanda zvakanaka kwekutumira data.
4. Edge Komputa
Kushandiswa kweEdge computing kunosimbisa kugadziriswa kwedata pedyo nemushandisi wekupedzisira kana mudziyo. Nehurongwa hwe5G, edge computing inogonesa kudzikira kwe latency uye kuvandudzwa kwekushanda kwemapurogiramu anonyanya kupindura panguva.
– MEC (Multi-access Edge Computing): Iyi tekinoroji inogonesa kugadziriswa kwedata remunharaunda panzvimbo dzakasiyana dzenetwork, nokudaro ichideredza kunonoka uye kuwedzera kushanda zvakanaka.
Mashandiro anoita 5G Networks
1. Kuvandudza Spectrum
5G inoshandisa frequency yakafara, kusanganisira kushandisa ma millimeter waves (mmWave), ayo anopa bandwidth yakakura asi ine kufukidza kushoma. Kushandiswa kwakanyanya kwe spectrum kunoita kuti data rakawanda ritumirwe.
2. Kuchinja-chinja uye Kunyora Makodhi
5G inoshandisa modulation yepamusoro-soro yakaita se256-QAM (Quadrature Amplitude Modulation) iyo inobvumira kutapurirana kwedata bits yakakwira pachiratidzo chimwe nechimwe.
3. Kunonoka Kwakaderera
Chimwe chezvakanakira zvikuru zve5G networks inonoka kwakanyanya, kunyangwe pasi pe1 millisecond. Izvi zvinogonesa maapplication anoda mhinduro chaiyo, senge mitambo yepamhepo, VR/AR, uye kutaurirana kubva kune mota kuenda kune mota (V2V).
Kushandiswa kwe5G muzvikamu zvakasiyana-siyana
1. Indasitiri yekugadzira
Muchikamu chekugadzira, 5G inogonesa otomatiki yepamusoro-soro kuburikidza neIndustrial IoT (IIoT). Michina nemarobhoti zvinogona kutaurirana neruzivo rwedata panguva chaiyo, zvichiwedzera kushanda zvakanaka uye zvichiita kuti zvigadziriswe zviri nani.
2. Hutano
Mukurapa, 5G inounza zvinhu zvitsva zvakaita sekurapa nefoni, kuvhiyiwa kuri kure kusinganonoki, uye kutarisa varwere panguva chaiyo.
3. Mota
Muindasitiri yezvemotokari, 5G inotsigira kugadzirwa kwemotokari dzinozvishandira dzega kuburikidza netekinoroji yeV2X (Mota kuenda kuZvese) iyo inoda kutaurirana nekukurumidza pakati pemotokari nezvivakwa.
4. Varaidzo neMidhiya
Kune vezvevaraidzo nevezvenhau, 5G inobvumira kuratidzwa kwemashoko ane resolution yepamusoro pasina buffer pamwe nekuona Augmented Reality (AR) neVirtual Reality (VR) zviri kuitika.
Matambudziko uye Remangwana re5G Networks
1. Zvivakwa
Kuvandudzwa kwezvivakwa zve5G kunoda mari yakawanda, kunyanya mukuisa masero madiki anodiwa kuti pave nekuchengetedzwa kwakanaka.
2. Kuchengetedzwa
Nekuwedzera kuri kuita huwandu hwemidziyo yakabatana nedata zviri kutumirwa, matambudziko ekuchengetedza ari kuva dambudziko guru kune network dze5G.
3. Mutemo
Kushandiswa kwe5G kunoda mitemo inotsigira kubva kuhurumende, kusanganisira kugoverwa kwema spectrum uye kuisa mitemo yetekinoroji.
4. Kushanda pamwe chete
Kushanda pamwe chete pakati pevatengesi netekinoroji yekare idambudziko guru mukuona kuti network dze5G dzakabatana uye dzinoshandiswa zvakanaka.
Mhedziso
Kugadzirwa kwenetwork ye5G kunounza shanduko huru dzinovhura mikana mikuru muzvikamu zvakasiyana-siyana. Nekumhanya kwakanyanya, kunonoka kushoma, uye kugona kubata zvishandiso zvakawanda, 5G ndiyo hwaro hweramangwana rakabatana uye rakangwara. Kunyange hazvo matambudziko ekushandisa achiripo, budiriro iyi inounza tariro itsva yekuvandudza mune ramangwana, ichichinja mamiriro edhijitari uye ichivandudza hupenyu hwese.
