Cellular Site Survey - ASCOM Myco 3 Troubleshooting Manual

Troubleshooting Tools
2. Place a radio or other audio source playing music next to the handset at the fixed location.
To be able to hear roaming delays, interruptions or distortions, a continuous audio source
from a radio or a PC/Smartphone is recommended. A conversation between two people often
consists of up to 50% of silent intervals and would not therefore be suitable for the test.
3. Walk around the site to find spots with weak coverage.
Make sure that the walk takes place both directions to ensure that the handset has roaming
options whenever the field strength drops low.
4. Make detailed notes of any areas where coverage is insufficient.
5. Perform a talk test with two people walking around the site. When done, document the results.

Cellular Site Survey

It is recommended to use cellular site survey tools to check a state of GSM, UMTS and LTE networks. Such
tools can provide support engineers with a true strength level measurement of the surrounding base
transceiver stations (BTS), can display locations of BTS, as well as analyze change dynamics. Additionally,
these tools can of beneficial use when it comes to the need to check the speed of the incoming and
outgoing connection, make cell ID logs, or create statistics of cell usage.
This section describes how to monitor the received signal strength on the handset as well as to locate other
cellular-related diagnostic information, for example service status, roaming information, and mobile network
type.
The information about the device's signal strength can be located through the:
• Settings menu – on the handset, go into the Settings > System > About phone > Status > SIM status.
• Field Test Mode – in the opened dialer, type *#*#4636#*#* and select Phone information.
