BEFORE YOU BEGIN
This manual explains how to set up and operate the Nemo Walker Air measurement tool software
developed by Anite Finland Ltd.
Nemo Walker Air is a portable engineering tool for measuring and monitoring the air interface of digital
networks. The supported network standards are:
GSM, WCDMA, HSPA, LTE, CDMA, EVDO, WIFI (HETNET)
Nemo Walker Air is an effective tool for tracing mobile networks. Nemo Walker Air collects
measurement results and stores them on log files, which are uploaded to FTP/HTTP server from the
Master unit or collected manually from Salve units. Measurement results provide useful information for
network optimization, verification, and maintenance purposes. Results can be efficiently and easily
viewed with the Nemo analysis tool Nemo Analyze for Windows®.
NOTES
When using the Nemo Walker Air test devices for measurement use, the battery operation time is
reduced from normal use. The best operation times will be achieved when the batteries are regularly
charged and discharged as instructed in the device user manual. See also other instructions and hints
from the device user manual regarding the battery use.

SETUP 15
after the first pairing the connection will be saved in the devices. Pairing is required for each
connection between the Master tablet and each Slave unit.
Note that it is advisable to name devices so that it is easy to distinguish them from
each other.
