Dagaalka loogu jiro dariiqyada teknoolajiyada 5G asal ahaan waa dagaal loogu talagalay guutooyinka soo noqnoqda. Waqtigan xaadirka ah, dunidu waxay isticmaashaa laba xabbo oo kala duwan oo soo noqnoqda si ay u geyso shabakadaha 5G, xadiga soo noqnoqda ee u dhexeeya 30-300GHz waxaa lagu magacaabaa millimeter wave; Midda kale waxaa loo yaqaan Sub-6, kaas oo ku urursan inta jeer ee 3GHz-4GHz.
Iyadoo la raacayo sifooyinka jireed ee hirarka raadiyaha, mawjadaha dhererka gaaban iyo calaamadaha cidhiidhiga ah ee hirarka millimitirka ayaa awood u siinaya xallinta calaamadaha, amniga gudbinta, iyo xawaaraha gudbinta in la wanaajiyo, laakiin fogaanta gudbinta ayaa si weyn loo dhimay.
Marka loo eego tijaabada daboolka Google ee 5G ee isla tirada isku midka ah iyo isla tirada saldhigyada saldhiga, shabakada 5G ee la geeyo mowjadaha millimitirka ayaa dabooli kara 11.6% dadweynaha oo ah 100Mbps, iyo 3.9% oo ah 1Gbps. 6-band 5G network, 100Mbps heerka network ayaa dabooli kara 57.4% dadweynaha, iyo 1Gbps waxa uu dabooli karaa 21.2% dadweynaha.
Waxaa la arki karaa in daboolka shabakadaha 5G ee ka hoos shaqeeya Sub-6 ay ka badan tahay 5 jeer hirarka millimitirka. Intaa waxaa dheer, dhismaha saldhigyada saldhigyada hirarka millimitirka waxay u baahan yihiin ilaa 13 milyan oo rakibo tirarka tamarta, taas oo ku kici doonta $ 400 bilyan, si loo hubiyo 72% caymiska 100 Mbps halkii labaad ee band 28GHz iyo qiyaastii 55 ilbiriqsi kasta 1Gbps. % caymis. Sub-6 kaliya wuxuu u baahan yahay inuu ku rakibo saldhiga 5G ee saldhiga asalka ah ee 4G, kaas oo si weyn u badbaadiya kharashka dajinta.
Laga soo bilaabo caymiska ilaa kharashka isticmaalka ganacsiga, Sub-6 wuu ka sarreeyaa mmWave muddada gaaban.
Laakiin sababtu waxay tahay in ilaha spectrum ay aad u badan yihiin, xadhkaha xadhkaha qaada wuxuu gaari karaa 400MHz/800MHz, heerka gudbinta wirelessku wuxuu gaari karaa in ka badan 10Gbps; tan labaad waa laydhka milimitir ee cidhiidhiga ah, jihada wanaagsan, iyo xallinta meelaha aadka u sarreeya; Midda saddexaad waa qaybaha milimitir-mawjadaha marka la barbar dhigo qalabka Sub-6GHz, way fududahay in la yareeyo. Marka afraad, inta u dhaxaysa gaadhi-hoosaadka waa weyn yahay, halka booska SLOT-ka (120KHz) waa 1/4 ee soo noqnoqda hoose ee Sub-6GHz (30KHz), daahitaanka is-dhexgalka hawadana waa la dhimay. Codsiyada shabakadaha gaarka ah, faa'iidada hirarka millimitirku waxay ku dhowdahay inay burburiso Sub-6.
Waqtigan xaadirka ah, shabakada gaarka ah ee isgaadhsiinta gawaadhida dhulka oo ay hirgelisay isgaadhsiinta millimeter-ka ee warshadaha gaadiidka tareenada waxay gaari kartaa heerka gudbinta 2.5Gbps ee xawaaraha sare ee xawaaraha sare, dib u dhigista gudbinta waxay gaari kartaa 0.2ms, kaas oo leh qiimo aad u sarreeya. horumarinta shabakadaha gaarka ah.
Shabakadaha gaarka ah, xaaladaha sida gaadiidka tareenada iyo la socodka amniga dadwaynaha waxay siin karaan ciyaar buuxda faa'iidooyinka farsamada ee hirarka millimitirka si loo gaaro xawaaraha 5G ee dhabta ah.
