Unit validates LTE base-station performance Product News 11/9/2012 Post a comment With Ixia’s XAir LTE UE (user equipment) emulation module, operators can perform complex subscriber modeling for end-to-end network testing—from the LTE base station, through mobile backhaul and core networks, all the way to the data center.
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
