Vodafone testeaza tehnologie femtocell (statiile de baza 3G de interior) pentru a imbunatati aria de acoperire pentru retelele 3G in interiorul cladirilor, informeaza presa de specialitate. In telecomunicatii, femtocell reprezinta o statie de telefonie mobila de dimensiuni reduse, ce contine tehnologii similare cu o statie standard, reduse, insa, la marimea unei carti. Aria de acoperire furnizata este limitata. Tehnologia fetmocell se afla, in mai multe privinte, in competitie cu cea UMA (Acces Mobil nelicentiat).

Fara statiile de acces femtocell, operatorii ar trebui sa mareasca numarul statiilor de baza d...
