Signalling Tester MD8475A/B is a base station simulator reproducing communications between base stations and UEs. It supports the full range of communication standards including 2G to LTE-Advanced, and multiple applications such as VoLTE, WiFi Offload etc. Its scenario-less GUI SmartStudio can simplify the test environment construction, assuring efficient tests of UEs become complicated. Supports multimode terminals LTE (2x2 MIMO), LTE-Advanced (2CA), W-CDMA/HSPA/HSPA Evolution/DC-HSDPA, GSM/GPRS/EGPRS, TD-SCDMA/TD-HSPA SmartStudio GUI supports easy setup of test environments and functional tests Built-in CSCF server function supports GUI-based IMS service tests, such as VoLTE Simple test mode using built-in CSCF server Script mode supporting complex test environments by creating SIP sequences for irregular tests, etc. LTE data throughput up to 300 Mbps* (downlink) and 50 Mbps (uplink) All-in-one DC-HSDPA 43.2 Mbps support All-in-one support for 2-cell test environment, including Inter-RAT Cell Reselection, Redirection, Cell Change, CS Fallback Supports offload tests from LTE/W-CDMA to WLAN Automated continuous 24/7 testing using SmartStudio Manager Automatically controls both Android smartphone and MD8475A More than 180 sample sequences available for immediate testing after setup Supports eCall/ERA-GLONASS tests, NG-eCall
