We were on the Barnett Mt tower site today to change frequencies again. After testing each subscriber I decided to only change the SW transmitter. It was at 911.6 to accommodate the Tranzeo, but since that's not necessary any more I was able to use 921.6. Service for all SW sub's improved significantly. Before the change every sub had packet loss, afterward only one sub showed any PL and they were a marginal installation to begin with.
Barnett-SE looked fine today when I was testing. We'll continue to monitor service closely to ensure the improvements aren't a fluke.
Also, Thursday the 20th we made our last efforts to get a solid radio link into Marshall from Barnett using the Tranzeo 900s. They failed miserably to perform well after much wasted time and effort. Now we need Plan B which I'm working on.

Marshall Back Haul update
Today I worked some more on the Tranzeo TR900 radios we're testing as BH for Madison Co into downtown Marshall. These radios continue to be problematic and to perform poorly in this case. I'm going to renew my search for anyone else using them to find if others have had similar problems. In theory they sound great, but we're having problems getting a solid, error-free link.
So I did now find some others with similar complaints about these radios and am planning to contact our distributer and possibly Tranzeo (again).

9-13-2007 update
Today we worked at the Barnett Mt tower site in Madison Co. This site provides Wireless Broadband to about 50 of our subscribers and is our busiest Community Access Point (CAP) in the county. Recently we are experiencing reduced throughput (bandwidth) for many sub's using this CAP. After much testing and monitoring I think I've confirmed the source as interference from another broadcast in the same frequency range, but I'm not going to name names until we've exhausted our efforts to resolve the issue cooperatively.
We did change frequencies on two of the transmitters, SE and SW, hoping to improve service to sub's in those areas. Preliminary testing doesn't show any substantial improvement and possibly some sub's are even worse off. We may have to go back up there tomorrow to reverse the changes.
Also, we have installed and are testing a new set of radios on the Barnett tower, Tranzeo TR900, which are intended to haul all of Madison Co Internet traffic to our new fiber drop in downtown Marshall. At present we Back Haul Madison Co traffic to our Internet Point Of Presence (POP) located in the Burnsville Town Hall.
Unfortunately the Tranzeos have proven to be problematic and aren't performing well. I thought I had found the solution to the issues with these new radios, but, while performance did improve significantly, the link is still too weak to use.
Hopefully nothing will catch fire or blow up in the next few days and I can stay focussed on this.
Interestingly, the performance issues with the Tranzeos is similar, if not identical to the issues with our other transmitters at this site. That being while signal strength and latency is mostly normal throughput is marginal at best. This seems to be classic interference caused by a particular type of radio which are present at the site. If this is the case, it's beginning to look like the only solution is for the interfering radios to be re-configured, modified, replaced or removed.
I can only hope that some cooperation is forthcoming from the operator of these radios, but to this point they have only denied the possibility of what are beginning to look like solid facts. I'm only the monkey, so we'll have to see how the organ grinders want to play this one.
