3 USING THE SOFTWARE FOR SYSTEM MAINTENANCE 

3.1 ANALYSING CONNECTION STRENGTH 

After the system is configured and all of the equipment is fitted, you can analsze the connection 
strength with wireless devices. To do that, open the 

Connection quality

 tab. 

 

 

This table allows you to see the connection strength with each device in the system. The

 Rating 

column shows connectivity levels with the devices on a scale from 2 to 5. It is recommended that 
connection with all devices is rated at least 4 or 5. The

 Actuality 

column tells you how much time 

has  passed  since  the  connectivity 
levels  have  been  updated.  By 

double-clicking

 on a device you can 

open  a  plot  of  connection  strength 
with  this  device  over  a  certain 
amount of time. 

 

This  plot  shows  the  current 

signal  strength  (higher  is 

better)

  and 

traffic  percentage  (lower  is  better)

  in  the 

network.  

 

The 

Wireless system network topology

 window shows how different expanders and wireless 

devices are interconnected with each other. In the example on the left, you can see that all four 
of  the  devices  are  connected  directly  to  the  translator.  The  bigger  the  system  is,  the  more 
complicated the graph will get. 

 

The colour of the line also represents the connection strength (e.g. 

green

 is a 5). You can also 

select the 

Full graph

 option to inspect backup communication routes. 

To  begin  analysuing  the  network,  turn 
on reading signal strength data
