In a UMTS Mobile Radio Network, it is essential to achieve accurate information about the receiving conditions of a mobile unit at any place and any time.
The first step (before the availability of reasonable test mobile stations TMS) is to implement a mobile unit to measure and identify all Node-B signals in the air.
According to UMTS/3GPP specification, numerous Node-B share one channel. Ideally, the total power of the serving cell is more than 20 dB higher than all other neighbors. In reality, this is impossible for a functioning network, and optimization work requires then the knowledge of all base stations that exceed this threshold of 20 dB distance.
Thus, every UMTS network operator needs a powerful instrument for "UMTS Interference Analysis" in his network.
The R&S®UMTS PN-Scanner can be configured to five different packages.
