node bee

node bee vishesh roop seey mobile sanchaar network mein dursanchar node haye, arthaat way joe yuu. aim. tii. aiss. maanak kaa paalan karate hain. node bee mobile phone (yuu. ee. aiss.) aur vyaapak telephone network key beach sambandh pradaan kartaa haye. umats pramukh 3jee maanak haye. 
node bee jee. aiss. aim. mein bee. tii. aiss. (bases transiver station) seey mell khaata haye.
karyakshamta.
yeh vaha hardware haye joe mobile phone network seey judaa huaa haye joe seedhe mobile handset key saath sanchaar kartaa haye. jee. aiss. aim. aadhar stations key vipareet, node bee vayu interfaces praudyogiki key roop mein doubleu. see. dee. aim. aeye./tii. dee.-aiss. see. dee. aim. aeye. kaa upayog kartaa haye. jaise kii sabhi cellular pranaliyon mein, jaise kii yuu. aim. tii. aiss. aur jee. aiss. aim., node bee mein radio aavritti transmitter (oun) aur receiver (oun) hotey hain joe seedhe mobile upkaranon key saath samvaad karane key liye upayog kiye jaate hain, joe isake chaaron or swatantra roop seey ghoomate hain. iss prakaar key cellular network mein, mobile upkaran ack dusare key saath seedhe samvaad naheen curr sakate hain, lekin unhein nodeb key saath samvaad karna padata haye.
paaramparik roop seey, node bee. aiss. mein nyuntam karyakshamta hoti haye, aur ack aar. aine. see. (radio network niyantrak) dwara niyantrit hotey hain. haalaanki, yeh uchch gati downlink paiket axes (hsdpa) key udbhav key saath badal rhaa haye, jahan kuchh tark (ee.jee., punah prasaran) koo cumm pratikriya samay key liye node bee parr sambhala jaataa haye.
ack node bee aur ack jee. aiss. aim. aadhar station key beach antar.
aavritti upayog.
doubleu. see. dee. aim. aeye. praudyogiki kaa upayog ack hii yaa alag node bee. aiss. seey sambandhit koshikaon koo anumati detaa haye aur yahaan taka kii alag-alag aar. aine. see. dwara niyantrit kiya jaataa haye taaki way ack hii aavritti kaa upayog curr sakein (vaastav mein, poore network koo kewal ack aavritti jodee key saath lagu kiya jaa sakata haye). prabhaav kaa upayog naram handover mein kiya jaataa haye.
bijli kii aavashyaktaaen.
choonki doubleu. see. dee. aim. aeye. aksar jee. aiss. aim. kii tulanaa mein uchch aavrittiyon parr kaam kartaa haye (jee. aiss. aim. key liye 900 aim. aich. jaid. key vipareet 2,100 aim. aich. jaid.), isaliye jee. aiss. aim. koshikaon kii tulanaa mein doubleu. see. dee. aim. aeye. key liye koshika trijya kaafee cumm hoe sakati haye kyonki path haani aavritti parr nirbhar haye. doubleu. see. dee. aim. aeye. key paas abb 850-900 mhz baind mein kaam karane vaale network hain. inn networkon mein, inn aavrittiyon parr, doubleu. see. dee. aim. aeye. kaa coverage samkaksh jee. aiss. aim. network kii tulanaa mein behtar maanaa jaataa haye.
jee. aiss. aim. key vipareet, koshikaon kaa aakar sthir naheen hotaa haye (ack ghatana jise "koshika shwas" key roop mein jaanaa jaataa haye). isake liye badee sankhya mein node bee. aiss. aur 3jee (yuu. aim. tii. aiss.) network mein saavdhaanipoorvak yojana banaane kii aavashyakta hoti haye. node bee. aiss. aur upayogkarta upkaran (yuu. ee.) parr bijli kii aavashyaktaaen bahut cumm hain.
yeh aaee. yuu. bee. interfaces key madhyam seey yuu. aim. tii. aiss. network key aar. aine. see. seey judaa huaa haye.
node bee setup.
ack poorna cell site mein ack cabinet, ack antina maast aur vaastavik antina hotaa haye. ack upkaran cabinet mein ee hotaa haye.jee. aar. aff. power emplifier, digital signal processor aur backup battery. aap sadak key kinare yaa shahar key kendra mein joe dekh sakate hain vaha sirf ack antina haye. haalaanki, aajkal antina koo chhipaane kii pravritti haye (ise imarat key rung seey pent karein yaa ise ack rf-pardarshi gheraav mein rakhein). chhote indor nodes mein cabinet key darwaaje mein ack antina banaaya jaa sakata haye.
ack node bee kaee koshikaon kii seva curr sakata haye, jinhen kshetra bhee kahaa jaataa haye, joe vinyas aur antina key prakaar parr nirbhar kartaa haye. samanya vinyas mein omni cell (360°), 3 sector (3 × 120°) yaa 6 sector (60 degree pratyek, bahut lokpriya pariniyojan naheen) shamil hain.
