5G LAN yog dab tsi?

Sau: Ulink Media

Txhua tus neeg yuav tsum paub txog 5G, uas yog kev hloov pauv ntawm 4G thiab peb cov thev naus laus zis kev sib txuas lus mobile tshiab.

Rau LAN, koj yuav tsum paub ntau dua nrog nws. Nws lub npe tag nrho yog thaj chaw hauv cheeb tsam, lossis LAN. Peb lub network hauv tsev, nrog rau lub network hauv chaw ua haujlwm, yog qhov pib LAN. Nrog Wireless Wi-Fi, nws yog Wireless LAN (WLAN).

Yog li vim li cas kuv thiaj hais tias 5G LAN yog qhov nthuav?

5G yog lub network dav ntawm tes, thaum LAN yog thaj chaw me me cov ntaub ntawv network. Ob lub thev naus laus zis zoo li tsis sib xws.

Hauv lwm lo lus, 5G thiab LAN yog ob lo lus uas txhua tus paub nyias. Tab sis ua ke, nws yog me ntsis ruam. Tsis yog nws?

5G LAN, Nws yog dab tsi?

Qhov tseeb, 5G LAN, kom nws yooj yim, yog siv 5G thev naus laus zis los "pab" thiab "tsim" terminals los tsim LAN network.

Txhua tus muaj 5G xov tooj. Thaum koj siv 5G xov tooj, koj puas tau pom tias koj lub xov tooj nrhiav tsis tau koj cov phooj ywg txawm tias lawv nyob ze (txawm yog ntsej muag)? Koj tuaj yeem sib txuas lus nrog ib leeg vim tias cov ntaub ntawv ntws mus rau cov servers ntawm koj tus neeg nqa khoom lossis chaw pabcuam hauv Is Taws Nem.

Rau lub hauv paus chaw nres tsheb, tag nrho cov mobile terminals yog "kev cais" ntawm ib leeg. Qhov no yog raws li kev xav txog kev nyab xeeb, cov xov tooj siv lawv tus kheej raws, tsis txhob cuam tshuam rau ib leeg.

Ib qho LAN, ntawm qhov tod tes, txuas cov terminals (cov xov tooj ntawm tes, khoos phis tawj, thiab lwm yam) hauv ib cheeb tsam ua ke los tsim "pab pawg". Qhov no tsis tsuas yog pab txhawb cov ntaub ntawv sib kis ntawm ib leeg, tab sis kuj tseem txuag cov kev tawm ntawm extranet.

Hauv LAN, cov davhlau ya nyob twg tuaj yeem nrhiav tau ib leeg raws li lawv qhov chaw nyob MAC thiab nrhiav ib leeg (Txheej txheem 2 kev sib txuas lus). Txhawm rau nkag mus rau sab nraud network, teeb tsa lub router, los ntawm qhov chaw nyob IP, tseem tuaj yeem ua tiav txoj hauv kev thiab tawm (txheej txheem 3 kev sib txuas lus).

Raws li peb txhua tus paub, "4G yuav hloov peb lub neej, thiab 5G yuav hloov peb lub neej". Raws li lub ntsiab lus tseem ceeb tshaj plaws ntawm kev sib txuas lus xov tooj ntawm tes tam sim no, 5G lub xub pwg nyom lub luag haujlwm ntawm "Internet ntawm txhua yam thiab kev hloov pauv digital ntawm ntau pua kab thiab ntau txhiab kev lag luam", uas xav tau los pab cov neeg siv hauv kev lag luam ntsug tau txuas nrog.

Yog li ntawd, 5G tsis tuaj yeem txuas txhua lub davhlau ya nyob twg rau huab, tab sis kuj tseem paub txog "kev sib txuas ze" ntawm cov terminals.

Yog li ntawd, hauv 3GPP R16 tus qauv, 5G LAN tau qhia txog qhov tshiab no.

Cov ntsiab lus thiab cov yam ntxwv ntawm 5G LAN

Hauv 5G Network, cov thawj coj tuaj yeem hloov kho cov ntaub ntawv hauv cov neeg siv database (UDM network cov ntsiab lus), kos npe rau daim ntawv cog lus kev pabcuam nrog tus lej UE, thiab tom qab ntawd faib lawv mus rau tib lossis sib txawv Virtual network pawg (VN).

Cov neeg siv cov ntaub ntawv muab cov ntaub ntawv xov tooj ntawm VN pab pawg thiab nkag mus rau cov cai tswj hwm cov ntsiab lus (SMF, AMF, PCF, thiab lwm yam) ntawm 5G core network (5GC). Kev tswj hwm NE muab cov ntaub ntawv no thiab cov cai tswjfwm rau hauv Lans sib txawv. Qhov no yog 5G LAN.

5G LAN txhawb nqa txheej txheej 2 kev sib txuas lus (ib ntu ntu sib txuas, sib txuas ncaj qha rau ib leeg) nrog rau txheej 3 kev sib txuas lus (nrog cov ntu ntu, nrog kev pab ntawm kev sib txuas). 5G LAN txhawb nqa unicast nrog rau kev sib tw thiab tshaj tawm. Nyob rau hauv luv luv, kev sib nrig sib nkag mus rau hauv lub hom yog hloov tau yooj yim, thiab lub networking yog heev yooj yim.

Hais txog qhov muaj peev xwm, 5G LAN txhawb nqa kev sib txuas lus ntawm tib UPF (media side network element ntawm 5G core network) thiab sib txawv UPFs. Qhov no yog tantamount rau kev rhuav tshem lub cev nyob deb ntawm cov terminals (txawm tias Beijing thiab Shanghai tuaj yeem sib txuas lus).

Tshwj xeeb, 5G LAN tes hauj lwm tuaj yeem txuas rau cov neeg siv cov ntaub ntawv sib txuas uas twb muaj lawm rau ntsaws thiab ua si thiab kev sib koom ua ke.

Daim Ntawv Thov Scenario Thiab Qhov Zoo ntawm 5G LAN

5G LAN ua rau muaj kev sib koom ua ke thiab kev sib txuas ntawm 5G terminals uas tau teev tseg, ua kom yooj yim rau kev tsim kho ntau lub xov tooj ntawm tes LAN rau cov lag luam. Ntau tus neeg nyeem paub tseeb yuav nug, puas yog tsis muaj kev txav mus los nrog Wi-Fi thev naus laus zis tam sim no? Vim li cas thiaj xav tau 5G LAN?

Tsis txhob txhawj, cia peb mus.

Kev sib txuas hauv zos tau qhib los ntawm 5G LAN tuaj yeem pab cov lag luam, tsev kawm ntawv, tsoomfwv, thiab tsev neeg sib txuas lus zoo dua nrog cov chaw nyob hauv ib cheeb tsam. Nws tuaj yeem siv tau rau hauv lub chaw ua haujlwm network, tab sis nws cov nqi ntau dua nyob rau hauv kev hloov pauv ntawm qhov chaw tsim khoom ntawm lub tiaj ua si thiab kev hloov pauv ntawm cov chaw tsim khoom lag luam xws li kev tsim khoom lag luam, chaw nres nkoj terminals thiab lub zog mines.

Peb tam sim no txhawb kev lag luam hauv Internet. Peb ntseeg tias 5G tuaj yeem ua rau digitalization ntawm kev lag luam scenes vim 5G yog qhov zoo tshaj plaws wireless kev sib txuas lus thev naus laus zis nrog cov bandwidth loj thiab qeeb qeeb, uas tuaj yeem paub txog kev sib txuas wireless ntawm ntau yam khoom tsim hauv kev lag luam.

Siv industrial manufacturing, piv txwv li. Yav dhau los, txhawm rau kom zoo dua automation, kom ua tiav cov cuab yeej tswj, siv "kev lag luam tsheb npav" thev naus laus zis. Muaj ntau hom kev siv tshuab no, uas tuaj yeem piav qhia tias "txhua qhov chaw".

Tom qab ntawd, nrog kev tshwm sim ntawm Ethernet thiab IP thev naus laus zis, kev lag luam tsim kev pom zoo, nrog rau kev hloov pauv ntawm Ethernet, muaj "kev lag luam Ethernet". Niaj hnub no, tsis hais leej twg yog kev lag luam kev sib txuas raws tu qauv, yeej yog Ethernet-based.

Tom qab ntawd, cov tuam txhab lag luam pom tias kev sib txuas ntawm cov xov hlau txwv tsis pub txav mus los ntau dhau - ib txwm muaj "braid" nyob tom qab ntawm lub cuab yeej uas tiv thaiv kev txav mus los.

Tsis tas li ntawd, qhov kev sib txuas ntawm kev sib txuas ntawm kev xa tawm yog qhov teeb meem ntau dua, kev tsim kho lub sijhawm ntev, tus nqi siab. Yog tias muaj teeb meem nrog cov khoom siv lossis cable, kev hloov pauv kuj qeeb heev. Yog li, kev lag luam pib xav txog kev qhia txog kev sib txuas lus wireless.

Yog li ntawd, Wi-Fi, Bluetooth thiab lwm yam thev naus laus zis tau nkag mus rau hauv kev lag luam.

Yog li, rov qab mus rau lo lus nug dhau los, vim li cas 5G LAN thaum muaj Wi-Fi?

Nov yog vim li cas:

1. Kev ua haujlwm ntawm Wi-nkaus tes hauj lwm (tshwj xeeb yog Wi-Fi 4 thiab Wi-Fi 5) tsis zoo li 5G.

Hais txog kev sib kis tus nqi thiab kev ncua, 5G tuaj yeem ua tau zoo dua qhov kev xav tau ntawm cov neeg hlau muaj kev lag luam (kev tswj hwm kev tswj hwm), kev tshuaj ntsuam xyuas zoo (kev lees paub cov duab nrawm), AGV ( tsheb tsis siv neeg thauj khoom) thiab lwm yam xwm txheej.

Hais txog kev them nqi, 5G muaj thaj tsam loj dua li Wi-Fi thiab tuaj yeem npog lub tsev kawm ntawv zoo dua. 5G lub peev xwm hloov pauv ntawm cov hlwb kuj muaj zog dua Wi-Fi, uas yuav ua rau cov neeg siv muaj kev paub zoo dua hauv network.

2. Wi-Fi network tu nqi yog siab.

Txhawm rau tsim kom muaj Wi-nkaus network hauv lub tiaj ua si, cov lag luam yuav tsum tau xaim thiab yuav lawv cov khoom siv. Cov khoom siv tau raug txo nqi, puas thiab hloov pauv, tab sis kuj tseem tswj hwm los ntawm cov neeg ua haujlwm tshwj xeeb. Muaj ntau tons ntawm Wi-Fi li, thiab kev teeb tsa yog ib qho hassle.

5G txawv. Nws yog tsim thiab tswj xyuas los ntawm cov tswv lag luam thiab xauj los ntawm cov lag luam (Wi-Fi piv rau 5G yog me ntsis zoo li tsim koj tus kheej chav piv rau huab xam).

Ua ke, 5G yuav raug nqi ntau dua.

3. 5G LAN muaj zog ntau dua.

VN pawg ntawm 5G LAN tau hais ua ntej. Ntxiv nrog rau kev sib cais ntawm kev sib txuas lus, lub luag haujlwm tseem ceeb ntawm kev sib koom ua ke yog kom ua tiav QoS (kev pabcuam theem) kev sib txawv ntawm cov tes hauj lwm sib txawv.

Piv txwv li, ib lub tuam txhab muaj chaw ua haujlwm network, IT system network, thiab OT network.

OT stands rau Kev Ua Haujlwm Technology. Nws yog ib lub network uas txuas cov kev lag luam ib puag ncig thiab cov khoom siv, xws li lathes, robotic arms, sensors, instrumentation, AGVs, monitor systems, MES, PLCS, thiab lwm yam.

Cov tes hauj lwm sib txawv muaj cov kev xav tau sib txawv. Qee qhov xav tau qis latency, qee qhov xav tau bandwidth siab, thiab qee qhov xav tau tsawg dua.

5G LAN tuaj yeem txhais cov kev sib txawv network ua haujlwm raws li pawg VN sib txawv. Qee lub lag luam, nws yog hu ua "micro slice".

4. 5G LAN yog yooj yim los tswj thiab ruaj ntseg dua.

Raws li tau hais los saum toj no, cov neeg siv kos npe cov ntaub ntawv tuaj yeem hloov kho hauv 5G UDM nes ntawm cov neeg nqa khoom rau pab pawg neeg siv rau hauv pawg VN. Yog li, peb puas yuav tsum tau mus rau tus neeg nqa khoom pabcuam txhua lub sijhawm peb yuav tsum tau hloov cov ntaub ntawv ntawm pab pawg ntawm lub davhlau ya nyob twg (sib koom, rho tawm, hloov pauv)?

Tau kawg tsis.

Hauv 5G tes hauj lwm, cov neeg ua haujlwm tuaj yeem qhib qhov kev hloov kho kev tso cai rau kev lag luam network cov thawj coj los ntawm kev txhim kho kev sib tshuam, ua kom muaj kev hloov kho tus kheej.

Tau kawg, cov lag luam tuaj yeem teeb tsa lawv tus kheej ntiag tug cov cai tswjfwm raws li lawv tus kheej xav tau.

Thaum tsim cov ntaub ntawv sib txuas, cov lag luam tuaj yeem teeb tsa kev tso cai thiab kev lees paub cov txheej txheem los tswj hwm VN pawg. Qhov kev ruaj ntseg no muaj zog dua thiab yooj yim dua li Wi-Fi.

Cov ntaub ntawv kawm ntawm 5G LAN

Cia peb saib cov txiaj ntsig ntawm 5G LAN los ntawm ib qho piv txwv tshwj xeeb hauv kev sib tham.

Ua ntej tshaj plaws, lub tuam txhab tsim khoom, muaj nws tus kheej lub rooj cob qhia, cov kab ntau lawm (lossis tshuab dhos), yuav tsum tau txuas PLC thiab PLC tswj qhov kawg ntawm lub network.

Txhua kab sib dhos muaj ntau yam khoom siv, kuj muaj kev ywj pheej. Nws yog qhov zoo tshaj rau nruab 5G modules ntawm txhua lub cuab yeej hauv cov kab sib dhos. Txawm li cas los xij, nws zoo li nws yuav kim me ntsis ntawm theem no.

Tom qab ntawd, kev taw qhia ntawm 5G kev lag luam rooj vag, lossis 5G CPE, tuaj yeem txhim kho tus nqi ua haujlwm. Tsim nyog rau wired, txuas nrog wired chaw nres nkoj (Ethernet chaw nres nkoj, lossis PLC chaw nres nkoj). Haum rau wireless, txuas nrog 5G lossis Wi-Fi.

Yog tias 5G tsis txhawb 5G LAN (ua ntej R16), nws tseem tuaj yeem paub txog kev sib txuas ntawm PLC thiab PLC maub los. Txawm li cas los xij, tag nrho 5G network yog Layer 3 raws tu qauv uas tso siab rau IP chaw nyob, thiab qhov chaw nyob hauv lub davhlau ya nyob twg tseem yog tus IP chaw nyob, uas tsis txhawb Layer 2 cov ntaub ntawv xa mus. Txhawm rau kom paub txog kev sib txuas lus kawg-rau-kawg, AR (Access Router) yuav tsum tau ntxiv rau ntawm ob sab los tsim ib lub qhov, encapsulate cov txheej txheem txheej txheem 2 hauv lub qhov, thiab coj mus rau qhov kawg ntawm cov phooj ywg.

Txoj kev no tsis yog tsuas yog ua kom qhov nyuaj, tab sis kuj nce tus nqi (AR router yuav tus nqi, AR router configuration manpower thiab lub sij hawm tus nqi). Yog tias koj xav txog kev cob qhia nrog ntau txhiab kab, tus nqi yuav staggering.

Tom qab kev taw qhia ntawm 5G LAN, 5G network txhawb kev xa ncaj qha ntawm Txheej Txheej 2 raws tu qauv, yog li AR routers tsis xav tau ntxiv lawm. Tib lub sijhawm, 5G network tuaj yeem muab txoj hauv kev rau cov davhlau ya nyob twg yam tsis muaj IP chaw nyob, thiab UPF tuaj yeem paub txog MAC chaw nyob ntawm cov davhlau ya nyob twg. Tag nrho lub network dhau los ua ib txheej txheej me me, uas tuaj yeem sib txuas lus nrog ib leeg ntawm txheej 2.

Lub ntsaws thiab ua si muaj peev xwm ntawm 5G LAN tuaj yeem ua tiav nws tus kheej nrog cov neeg siv khoom cov kev sib txuas uas twb muaj lawm, txo qhov cuam tshuam rau cov neeg siv khoom cov tes hauj lwm uas twb muaj lawm, thiab txuag tau ntau tus nqi yam tsis muaj kev kho dua tshiab thiab kho dua tshiab.

Los ntawm kev pom macro, 5G LAN yog kev sib koom tes ntawm 5G thiab Ethernet thev naus laus zis. Nyob rau hauv lub neej yav tom ntej, txoj kev loj hlob ntawm TSN (lub sij hawm rhiab network) tshuab raws li Ethernet technology yuav tsis raug cais los ntawm kev pab los ntawm 5G LAN.

Nws yog ib qho tsim nyog hais tias 5G LAN, ntxiv rau qhov ua tau zoo rau kev tsim kho lub network sab hauv ntawm lub tiaj ua si, kuj tseem tuaj yeem siv los ua ib qho ntxiv rau cov kab ke ib txwm siv ntawm cov lag luam los txuas cov ceg ntoo hauv ntau qhov chaw.

Module rau 5G LAN

Raws li koj tuaj yeem pom, 5G LAN yog ib qho tseem ceeb ntawm cov thev naus laus zis tshiab rau 5G hauv kev lag luam ntsug. Nws tuaj yeem tsim kom muaj zog 5G kev sib txuas lus ntiag tug ntiag tug los pab cov neeg siv khoom nrawm lawv cov kev hloov pauv digital thiab hloov kho dua tshiab.

Txhawm rau kom siv tau zoo dua 5G LAN, ntxiv rau kev hloov kho sab hauv network, 5G module txhawb nqa kuj tseem xav tau.

Hauv cov txheej txheem ntawm 5G LAN thev naus laus zis kev lag luam tsaws, Unigroup Zhangrui tau tsim kev lag luam thawj 5G R16 Npaj Baseband nti platform - V516.

Raws li lub platform no, Quectel, tus thawj coj module tsim nyob rau hauv Suav teb, tau ntse tsim ib tug xov tooj ntawm 5G modules txhawb 5G LAN technology, thiab tau ua lag luam, xws li RG500U, RG200U, RM500U thiab lwm yam LGA, M.2, Mini PCIe pob modules .
