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. The hardware unit, which accommodates one sector, works with the company’s XM and XG chassis and load modules to enable the testing of multiple sectors.
XAir addresses three critical areas of LTE network validation:
realistic subscriber and service modeling, massive scalability, and
comprehensive QoE measurements. All three elements are required to
properly evaluate LTE base stations. XAir’s subscriber modeling supports
web, voice (VoLTE), and video applications; all LTE mobility types; and
radio characteristics, including cell edge, cell center, and user
Each XAir board emulates more than 1000 connected
active UEs (more than 6000 UEs per chassis). In addition to a built-in
10-MHz clock for eNodeB synchronization, the 1U module provides three
1-GigE, one 10-GigE, and four optical SFP/CPRI ports. It can be directly
interfaced with an eNodeB or Ixia’s remote radio-head units, which
cover all FDD and TDD frequency bands.
