WAPA is a tool for capturing wireless signals of 3G mobile networks Uu(UMTS Air Interface) among UTRAN(UMTS Terrestrial Radio Access Network) and analyzing protocol and traffic appeared in Uu.
It can monitor 8cell simultaneously and analyze DCH of DL(DownLink)/UL(Uplink) related to maximum 16UE in 8cell. In addition, HSDPA of 4UE and HSUPA traffic of 1UE of each 4 cells can be monitored simultaneously as well.
< Major Components of WAPA system (Unit) >
WIPU convert the down-converted I/F analog signal to digital.
