Ku qorayska BBU (Baseband Unit) waa qorsho network oo ku xusanaya wixii u soo saaray Baseband ee la kala qoray cell site-ka oo ku qoraysa tokomaha ama laba tokomaha oo ka mid ah, oo leh hawsha in la kala so celi kharashaada, uga buuxiyo xadka awoodda, iyo in la kor ugu yeeli network-ka. D RAN (Distributed RAN) qadadood, halka BBU-yo ay ku jirta RRU-yo (Remote Radio Units) ee cell site kasta, ku qorayska xadgudbada waxay xiran karta RRU-yada ku qoraysa BBU pool-ka caafimaadka fronthaul (khayt ama microfoonka cad gudbi), oo kuu ogola in la isku dayo awoodda processing-ka. Aragtida wuxuu kuu ogola in uu network operator-ka sii wacdo BBU capacity-ka oo kala iibsaday in la isku dajyo xawaalaha dambeynta ee dambeynta, si aan ugu badayo awoodda celceliska bulshada ee leh shacabka ugu badan, iyo in la sii wacdo bulshada ee la socda guduhu, tusaale ahaan, in la kala so celi awoodda la soo saaray site-ka kasta. BBU-yada ku qoraysay sidoo kale wuxuu network management-ka isku dayaa: software upgrades, hardware maintenance, iyo troubleshooting waxaa laga sameeyaa tokomka, oo ugu yaraanayo wakhtiga la guulaysta iyo wakhtiga la joojinayo. Iyadoo kale, horumarinta jirrka waxaa laa kor ugu yeeli, khayrka shararka ee jirrka iyo jirrka ee la sharay tokomka ugu dhexeeya waxay kala soocdaa kharashaada jirrka ee kala duwan ee D RAN site-ka la kala qoray. Laakiin, sidii la helo waxaa lagu jiraa in la kala so celi fronthaul-ka: hooseyska hoose (hoose 10 ms ee 5G) iyo bandwith weyn (10+ Gbps per RRU) waxay muhiim u tahay in la ilaaliyo saxaafka iska, khaytka oo ah meelaha la filayo ee fronthaul. Guud ahaan, operator-ka waxay ku qaybayaan ku qorayska BBU-yada tokomada leh xawaalaha ugu badan, oo isticmaala iisa badan, halka la isku dayo naqshadaha la kala qoray bulshada ee la soo saaray, halka xadka fronthaul-ka ay tahay in la kala jirin. Si 5G iyo in la soo saaray network-ka leh horumarinta, ku qorayska BBU-ka waxay noqonaysaa asalka ee virtualized iyo cloud based RAN (vRAN, C RAN), oo la isku dayaa in la kor ugu yeeli horumarinta sidaa loo soo gaabiyay.
