2. UE Dongle Performance Check Step1: Check UE Throughput at Good RSRP and SINR point using the same laptop If downlink throughput of one UE is much worse than other UEs, don’t use this UE to do FTP
. If uplink throughput of one UE is much worse than other UEs, don’t use this UE to do FTP .
Step2: Check UE Short Call Performance Observe the RRC Signalling of UE Short Call. If the message of ueCapabilityInformation is similar with the following figure, this UE can be used to do Short Call.
If the message of ueCapabilityInformation is similar with the following figure, this UE cannot be used to do Short Call.
The following table shows one example of check results. UE Name

4. Antenna Number and Location Check Step1: Check UE External Antenna Number One LTE UE must be connected with 2 external antennas to 2x2 MIMO. So 4 antennas are needed to do 2 test cases in one circle. Step2: Check UE External Antenna Location on the top of car 2 external antennas of one UE should be different side of car to get better MIMO performance, e.g.
one antenna out of left window and the other out of right window The following figure shows one example from sky view.

5. Drive Test Time Check The test case of FTP should be tested in the morning and finish before 14:00pm to get higher downlink throughput. The main reason is that there are some other commercial UEs doing
downlink service in the afternoon. The following table shows one example of drive test time schedule.
9:00am ~ 13:00pm First Circle FTP DL & Ping
13:00pm~14:00pm Lunch Non
14:00pm~18:00pm Second Circle FTP UL & Short Call
6. Drive Test Route Check The drive test should be done along the route confirmed with customer. For swap project, the DT
route After Swap should be same as that of Before Swap. The following figure shows one example of DT route in map.
