PXT to PXT Handover
Two PXTs can be used together to emulate two LTE base stations. This enables you to test the ability for
multi-band wireless devices to perform LTE handovers within the same frequency (intra-frequency) or
between two different frequencies (inter-frequency/inter-band).
The PXTs are designated as master (the PXT – cell A where the UE is initially connected) and slave (the
original target PXT- cell B). These notations are consistent throughout the handover process.
The following test scenarios are supported using the PXT/PXT combination:
• Cell reselection between LTE and LTE (bi-directional, UE-initiated only).
• Cell redirection/handover between LTE and LTE (bi-directional, BSE-initiated only).

Setting the Handover Parameters
1. Set the Cell ID to be different for both PXTs. For example: Cell ID 1 = 0, Cell ID 2 = 2
2. Set two different IP addresses for the PXTs:
a. Master: 192.168.1.60 (Set by selecting: Config > Network Settings > IP Setup > IP)
b. Slave: 192.168.1.61 (Set by selecting: Config > Network Settings > IP Setup > IP)
