39. Read This Before You Start Drive Testing

This chapter sums up some especially important prerequisites and necessary preparations for drive testing with TEMS Investigation.

Make sure that all external devices have adequate power supply.

During drive testing, it must be ensured that the PC and all devices connected to it have adequate and uninterrupted power supply for the duration of the test. This is especially important to bear in mind if you are using a USB hub that is not self-powered (i.e. has no external power supply). A separately powered USB hub (USB 2.0 or later) is strongly recommended for drive tests.

With multiple devices connected, it may even be necessary to take the precaution of providing extra power via UPS or extra batteries during drive testing. If the power provided is insufficient, problems may arise with device drivers, which in turn may cause malfunctions in Windows and possibly data loss. Infovista takes no responsibility for such data loss.

Make sure that appropriate drivers are installed for all external devices.

When doing data collection in LTE networks or in other scenarios that entail a high CPU load, it is strongly recommended for performance reasons to disable non-vital PC functions that consume a lot of processing power, especially visual effects.

Make sure that all Voicemails are disabled during testing.
