GL Communications Inc.
Communications Network Lab (2G, 2.5G, 3G, 4G, IP, TDM)

4G LTE Communications Network Lab

GL offers an End-to-End 4G  LTE Communications Network Lab (CNL) with all components such as eNodeB, MME, Serving Gateway, PDN Gateway, HSS, SGSN, PCRF, PCEF, AF and others to simulate both E-UTRAN and EPC (Evolved Packet Core), allowing complete testing of the LTE network.

One can setup a complete virtual real-time network simulating all the network elements, or any of the network elements in the above architecture can be replaced with user's DUT to perform single interface, multi-interface, or wrap-around testing. Complex scenarios such as handovers can be achieved easily.

The lab setup can include multiple eNodeBs configured to handle multi-UEs. Simulate multiple instances of nodes in network such as MME, SGW, and PGW to perform functional and load/stress testing.

Verify your latest mobile features over the network with various types of traffic generators and receivers. MAPS™ GTP mobile traffic (ETH101, ETH102) simulation support allows generation and verification of data traffic such as Email, FTP, Web (HTTP), Video, and transparent access to the IP network.
