He aha ka ʻokoʻa ma waena o ka ʻenehana 4G a me 5G

3G - ua hoʻololi ke kolu o ka hanauna kelepona i ke ʻano o kā mākou kamaʻilio ʻana me ka hoʻohana ʻana i nā polokalamu kelepona.Hoʻonui ʻia nā pūnaewele 4G me ka ʻoi aku ka maikaʻi o ka ʻikepili a me ka ʻike mea hoʻohana.Hiki iā 5G ke hāʻawi i ka broadband mobile a hiki i 10 gigabits i kēlā me kēia kekona ma kahi latency haʻahaʻa o nā milliseconds.
He aha ka ʻokoʻa nui ma waena o 4G a me 5G?
Ka māmā holo
I ka hiki ʻana mai i ka 5G, ʻo ka wikiwiki ka mea mua e hauʻoli ai nā mea a pau e pili ana i ka ʻenehana.Hiki i ka ʻenehana holomua LTE ke hiki i ka helu ʻikepili a hiki i 1 GBPS ma nā pūnaewele 4G.E kākoʻo ka ʻenehana 5G i ka helu ʻikepili a hiki i 5 a 10 GBPS ma nā polokalamu kelepona a ma luna o 20 GBPS i ka wā hoʻāʻo.

Hiki iā 5G ke kākoʻo i nā noi ikaika ʻikepili e like me 4K HD multimedia streaming, augmented reality (AR) a me nā noi virtual reality (VR).Eia kekahi, me ka hoʻohana ʻana i nā nalu millimeter, hiki ke hoʻonui ʻia ka helu ʻikepili ma luna o 40 GBPS a hiki i 100 GBPS i nā pūnaewele 5G e hiki mai ana.

ʻOi aku ka nui o ka bandwidth o nā nalu millimeter i hoʻohālikelike ʻia me nā kaha haʻahaʻa bandwidth i hoʻohana ʻia i nā ʻenehana 4G.Me ka bandwidth kiʻekiʻe, hiki ke hoʻokō ʻia ka nui o ka ʻikepili.
Latency
ʻO Latency ka huaʻōlelo i hoʻohana ʻia i ka ʻenehana pūnaewele e ana i ka lohi o nā ʻeke hōʻailona e hiki mai ana mai kekahi node a i kekahi.Ma nā pūnaewele paʻa lima, hiki ke wehewehe ʻia ʻo ia ka manawa i lawe ʻia e nā hōʻailona lekiō no ka huakaʻi mai ke kahua kahua a i nā polokalamu kelepona (UE) a me ka hope.

Aia ka latency o ka pūnaewele 4G ma waena o 200 a 100 milliseconds.I ka hoʻāʻo ʻana o 5G, hiki i nā ʻenekini ke hoʻokō a hōʻike i kahi latency haʻahaʻa o 1 a 3 milliseconds.He mea koʻikoʻi ka latency haʻahaʻa i nā noi koʻikoʻi nui a no laila ua kūpono ka ʻenehana 5G no nā noi latency haʻahaʻa.
Ka laʻana: nā kaʻa kaʻa ponoʻī, ʻoki mamao, hana drone etc.
ʻenehana kiʻekiʻe

I mea e hoʻokō ai i nā lawelawe ultra-wikiwiki a haʻahaʻa haʻahaʻa, pono e hoʻohana ʻo 5G i nā huaʻōlelo pūnaewele holomua e like me nā nalu millimeter, MIMO, beamforming, kamaʻilio ʻana i nā mea hana a me ke ʻano duplex piha.
ʻO ka wehe ʻana o Wi-Fi kekahi ala ʻē aʻe i manaʻo ʻia ma 5G e hoʻonui i ka pono o ka ʻikepili a hōʻemi i ka ukana ma nā kahua kahua.Hiki i nā polokalamu kelepona ke hoʻohui i kahi LAN uʻuku i loaʻa a hana i nā hana āpau (leo a me ka ʻikepili) ma kahi o ka hoʻopili ʻana i nā kahua kahua.
Hoʻohana ka ʻenehana holomua 4G a me LTE i nā ʻenehana modulation e like me Quadrature Amplitude Modulation (QAM) a me Quadrature Phase-Shift Keying (QPSK).I mea e lanakila ai i kekahi o ka palena o ka 4G modulation schemes, ʻoi aku ka kiʻekiʻe o ka mokuʻāina ʻo Amplitude Phase-Shift Keying technique kekahi o ka noʻonoʻo ʻana no ka ʻenehana 5G.
Hoʻolālā pūnaewele
I nā hanauna mua o nā pūnaewele kelepona, aia nā Radio Access Networks kokoke i ke kahua kahua.He paʻakikī nā RAN kuʻuna, pono ke kumu kūʻai nui, mālama i ka manawa a me ka hiki ke kaupalena ʻia.

E hoʻohana ana ka ʻenehana 5G i Cloud Radio Access Network (C-RAN) no ka ʻoi aku ka maikaʻi.Hiki i nā mea hoʻohana pūnaewele ke hāʻawi i ka pūnaewele ultra-wikiwiki mai kahi kikowaena lekiō e pili ana i ke ao.
Pūnaewele o na mea
ʻO ka Internet of Things kekahi huaʻōlelo nui i kūkākūkā pinepine ʻia me ka ʻenehana 5G.E hoʻopili ʻo 5G i nā piliona o nā polokalamu a me nā naʻau akamai i ka pūnaewele.ʻAʻole like me ka ʻenehana 4G, hiki i ka pūnaewele 5G ke lawelawe i ka nui o ka ʻikepili mai nā noi he nui e like me ka home akamai, IoT ʻenehana, mālama olakino akamai, nā kūlanakauhale akamai a me nā mea ʻē aʻe.

ʻO kahi noi nui ʻē aʻe o 5G ʻo ia ka mīkini i ka mīkini ʻano kamaʻilio.E alakaʻi ʻia nā kaʻa autonomous i nā ala e hiki mai ana me ke kōkua o nā lawelawe haʻahaʻa haʻahaʻa haʻahaʻa 5G.
Narrow Band - Nā noi pūnaewele o nā mea (NB - IoT) e like me ke kukui akamai, nā mika akamai, a me nā hoʻonā kaʻa kaʻa akamai, e kau ʻia ka palapala ʻāina me ka hoʻohana ʻana i ka pūnaewele 5G.
Nā hāʻina Ultra hilinaʻi
Hoʻohālikelike ʻia me 4G, e hāʻawi nā polokalamu 5G i ka wā e hiki mai ana i nā hopena pili mau, hilinaʻi nui a maikaʻi loa.Ua wehe ʻo Qualcomm i kā lākou modem 5G no nā polokalamu akamai a me nā kamepiula pilikino e hiki mai ana.

Hiki iā 5G ke mālama i ka nui o ka ʻikepili mai nā piliona o nā polokalamu a hiki ke hoʻonui ʻia ka pūnaewele no ka hoʻonui.He palena ko 4G a me nā pūnaewele LTE i kēia manawa ma ke ʻano o ka nui o ka ʻikepili, ka wikiwiki, ka latency a me ka scalability pūnaewele.Hiki i nā ʻenehana 5G ke hoʻoponopono i kēia mau pilikia a hāʻawi i nā hopena kūpono i nā mea lawelawe a me nā mea hoʻohana hope.
