Putere electrica instalata antena GSM 3G si 4G

Recommended Posts

Stie cineva care este puterea electrica instalata la o antena GSM 3G sau 4G folosita de cei de la telefonia mobila, gen orange, telekom sau digi (RCS-RDS) ???

De asemenea, ma interesa cum se alimenteaza antenele astea in mediu rural ?  :scratchchin:

poterea instalata-puterea insumata a consumatorilor  in acel punct de consum

Pentru o acoperire de 20Km raza, am citit ca se foloseste o putere de 40W si puterea depinde de relief.

Aceasta statie are puterea in functie de trafic si la trafic mic puterea poate scadea la 11W.

Alimentarea poate fi din reteaua electrica si pentru functionarea sigura poate contine dispozitive

 de putere autonome.

Asa putin, numai 40W ? Aveti idee ce aparatura se foloseste pe antentele astea ? Ma gandeam ca as putea sa caut niste specificatii tehnice si asa as fi mult mai sigur de puterea electrica necesara!! Cred.  :scratchchin:

Se pot studia si articolele despre statiile Ericsn si Nokia-Siemens.

The RBS6000 is an indoor Radio Base Station with one to four carriers and one to  six sectors at 20/40 Watt RF output power per carrier.

Sunt date despre puteri absorbite din retea si surse auxiliare, dar si puterile de RF.

Digi foloseste statii Motorola. 

 

Succes!

Mersi pentru docs.

Tocmai analizam placile de baza de aici:

Uau, am ramas masca cand am vazut densitatea componentelor si constructia in sine.

Si vazand puterea electrica absorbita, de ce astia de la telefonia mobila nu-si extind acoperirea ? Mai sunt zone in care semnalul GSM lipseste!!!  :ermm:

 Am un prieten fost programator de statii Ericsson, actualmente lucreaza la divizia de cercetare Vodafone, pe care -am rugat sa-mi explice

  care este bataia maxima si configurarea soft pentru aceasta. Pentru inceput i-am propus o bataie de 40Km. Dupa multe zile de intrebari

  la diverse nivele, raspunsul a venit, o receptie sigura se poate face cu statii Ericsson pina la 35Km teren plan.

Aceasta nu datorita puterii limitate sau configuratiei blocurilor functionale, ci datorita principiului de functionare.

In propagarea undelor radio, in multe conditii atmosferice se produc abateri de faza si intirzieri de grup care fac receptia instabila.

Acum, din punctual de vedere al furnizorului de telefonie mobila, de ce ar instala statii ce duc la un cost poate si de 50000$

 si care consuma curent electric, revizii taxe, etc. daca traficul este de citeva sute de convorbiri zilnic.
