| | Radio Frequency Problem - RF Cafe Forums |
Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would
be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate
that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views.
It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if
you would like to post something on RF Cafe's
Facebook page, please do.
Below are all of the forum threads, including all
the responses to the original posts.

Location: London UK | This is a complex issue. The ITU-R subcommittees have addressed some aspects, particularly in relation to the carrier to noise ratio versus bit errors and block error rates. In the context of asynch framed bit streams the answer depends on what QAM constellation you use. However, the re-try rate for IP based systems, and hence the impact on latency, I do not believe has been covered. Perhaps you may know how one relates to the other. Check out the ITU Radio subcommittees.

Posts: 2 | Hi lankapala,
When you encounter radio communication problems, the configuration of the Wlan devices can be the cause of the radio failure. You must configure certain parameters properly for the devices to communicate successfully. If you configure the parameters incorrectly, the problem that results appears to be a problem with the radio. These parameters include the Service Set Identifier, frequency, data rate, and distance.
