SEA 3705 and SEA 3706 extension modules
The SEA 3705 and the SEA 3706 are extension modules to further increase the number of channels. Up to 2 extensions can be connected to the base units.
Like the SEA 3714C and SEA 3709C base devices, the modules can acquire all network technologies from 2G (GSM), 3G (UMTS), 4G (LTE) and 5G NR in Stand Alone (SA) or Non-Stand Alone (NSA) mode. In this process, not only cell information but also neighboring cell information and quality parameters are acquired and recorded, e.g. LAC, ECID, CID, TAC, RSSI, etc.
