eNodeB / gNodeB simulator is a very useful, powerful and portable solution allowing to monitor, test and troubleshoot 4G or 5G core network. It simulates an ideal radio access network (4G, 5G/NSA/SA) and performs any data test by performing activities of up to 8 users. Tests can be driven from internal engine or up to 4 external T&M equipments can be connected. It’s features give a wide range of possibilities to combine any type of test (iperf, TCP/IP, http, streaming, ...) on ad hoc or regular basis and thus giving the operator a powerful means for keeping the network in the best condition.

Dimensions: 254 x 226 x 66 mm

CPRI

CPRI RF spectrum analysis

FPGA IP core performs CPRI RF spectrum analysis of 4G radio signal of all major vendors. The core automatically detects parameters of the signal. All the line rates are supported.

CPRI data logger and player

The IP core allows recording live CPRI data in real time, save them on a disk and replaying them the same way as they were transmitted. IP core implements a special way to save bandwidth between FPGA and disk. Recording time duration is limited by the disk capacity.

Multi SIM card reader allows connecting up to 8 SIM cards, 2FF format and performs communication with the SIM cards according to ISO 7816 and CCID standards. The reader is connected either by USB (conforming to PCSC-lite, pcsclite.apdu.fr) or ethernet interface to the server. USB provides also powering the board. Either 4 or 8 SIM ports version is possible.

Dimensions: 90 x 70 mm
