Troubleshooting a GPRS test failure. 

There are a number of reasons why a GPRS test may fail, 

 

the following points should be checked before calling HWM support for 
assistance:- 
 

Possible Problem 

Solution 

Network Busy due to 
excessive traffic. Commonly 
occurs around schools. 

Retry the test after a few 
minutes. 

GPRS signal not available at 
your location. Not all Cell 
masts carry GPRS traffic 

The logger will call into the data 
warehouse once per day using 
an SMS message; relocate the 
logger if more frequent 
communications is required. 

Network signal not strong 
enough. You need a CSQ 
(reported by the GPRS test) 
of at least 8 for reliable 
communications. 

Relocate the antenna if possible 
or try alternative antenna 
configurations. Ensure antennas 
are vertically orientated where 
possible. See Antenna 
placement notes section. 

APN settings incorrect. 

The GPRS tester knows about a 
large number of cellular networks 
and will try as many settings as 
possible and correct any error 
automatically.  
If there is still a failure, then you 
need to check with your network 
operator that you have the 
correct settings for your SIM. 

 

If you continue to experience problems with communication, you may need to 
check the network coverage in your location.
