RF Testing Utility

Sun Apr 12, 2009 12:52 am

Is there any way to orce the wireless devices to go into a test mode and do a continuious transmit on a specific frequencey or even just send builk data out the wireless interface. The reason i would like to do this is two fold.

1. Test the true cignal levels between two links on a loaded network showing the available channel bandwith on the receiving spectrium analiser and testing the antennas performance/spread to various locations.

2. To enable the allignment of links to be optimsed against interferance and nose from adjacent links and to see where harmonics and interferance on other equipment located at that site may be causing problems.

Currently the only way we can do this is by either using a 2.4Ghz RF transmitter or alternative equipment that has this feature.

Regards
Andrew

If you have a link set up already (ie. a station and an AP are associated), you can run a Bandwidth Test (Tools -> Bandwidth Test in WinBox). This will flood the link with traffic.

Thanks, Yes i have used this however its no good for testing antennas. its fine for doing some testing like wathing the RF lobes however one thing i have seen is that the bandwith tests are not exactl stable in a noisey enviroment.

So if I understand you correctly, you want the wireless interface to just blurt out RF, without expecting an ACKnowledgement.

In that case you can try setting the wireless interface mode to "alignment-only". I'm not sure what this does since I've never used it, but I would expect that it transmits some form of alignment packet continuously.

No harm in trying it out.

I second this request. I need MT to provide reasonably constant transmitting (independable of number of clients, or traffic) so I can make proper measurements using spectral analyzer. in this mode I do not even require any connection protocol, or to maintain connections, just simple solid transmission that may be measured.
