Verifying Signal Strength and Connection Status
The connection quality and signal strength can be checked while on site using the PLUS3 logger.
To check signal and connection status, press [Home][3][4]. Wait for the menu to change while the iPack
powers up. Then press [2]. A message will tell you if service is available and will display the strength of
the signal as a percentage. In this screen, additional detail such as cellular band and carrier are also
available.
The signal strength can be verified by directly connecting the iPack to a computer and running the
“Antenna Test” from the SDR software.
GSM iPackGPS, CDMA iPacks and Iridium satellite iPacks will display Signal Strength as a percentage.
Older GSM iPack antenna tests using SDR will give a Signal Strength value between 0 and 31, followed by
a Bit Error Rate value between 0 and 7.
Note that signal strength found on a fair weather day is optimistic, and local conditions can dramatically
affect connection reliability. Cell radio signals are weakened by local cellular traffic, rain, and even high
humidity in the signal path.
To view:
IP address, press [1]
DNS1, press [2]
DNS2, press [3]
Cellular Band, press [7]
Cellular Carrier, press [8]
For example, pressing [Home][3][4], wait, [2], [8] on an iPackGPS will bring up the screen:
iPackGPS v62 3G
Registered Roaming
AT&T
Batt: 12.8 Ant: 75% +
Older iPacks (pre-GPS model) do not have the additional detail available and will display:
