Depending on your indoor test needs, Agilent recommends different options. Three basic
types of indoor measurement systems are phone-based, receiver-based, and phone and
receiver-based. The following scenarios describe the type of system typically required for
various tests.
Measuring an indoor test transmitter To make CW transmitter measurements in the building you want to characterize, you first set
up a CW test transmitter somewhere in the building and then make CW measurements to
determine the effectiveness of the test transmitter’s antenna location. For this task, a
receiver-based system is required to perform the CW measurements.
A phone- and receiver-based system is more desirable because it allows you to make CW
measurements of the test transmitter using the receiver, and signal strength measurements
of the existing outdoor network using a phone.
You may need to measure the current state of the coverage in a building in order to
determine what additional coverage needs to be added. A phone-based system can be
used to perform this task only if the existing coverage is adequate enough to maintain a call.
A receiver-based system is effective in areas of poor coverage because it does not depend
on any communication with the network in order to make measurements.
A dual receiver system may be required for dual-band networks or where there is multiple
technology coverage.
Troubleshooting indoor coverage If you need to determine the cause of poor indoor service, you can make measurements to
determine why calls are being dropped or why voice quality is poor. A phone- and receiver-
based system is required to perform this indoor troubleshooting. The phone is used to verify
that a problem exists, and the receiver to determine the cause of the problem.
Measuring the coverage provided by
the outdoor network
The E6474A drive-test system supports data measurement options for optimization of
wireless data networks, essential in the roll-out of 2.5G and 3G networks. It provides the
sequencing of various data transaction scenarios to commercial FTP or http servers and to
Agilent's data server application, giving comprehensive measurements of IP and Application
layer quality of service parameters, from a wireless users perspective. Please refer to the
Agilent Wireless Data Measurement Product Overview (5980-2310E) for further information.
