AMARI Callbox Classic

Packaged in a plug and play integrated PC, AMARI Callbox Classic is an ideal solution for LTE and NR testing of all types of user equipment with advanced configuration.

It acts as a 3GPP compliant eNodeB, gNodeB, EPC and 5GC allowing functional and performance testing of NR, LTE, LTE-A, LTE-M and NB-IoT devices. The offer is completed by an integrated IMS server as well as an eMBMS gateway for VoLTE and eMBMs testing.

The Callbox is powered by a deployment quality LTE and NR software suite offering the same level of baseband functionality as an indoor/outdoor network.
