|Why “diversity” isn't enough.|
|Written by Ira S. Faberman, Iftron Technologies, Inc.|
But that's when all the trouble starts. It turns out that selecting the best signal seems easy at first glance, but is no easy task. Take diversity systems that work on received signal strength (RSSI for short) as an example. It seems clever to monitor the signal strength of each signal and pick the strongest one, because the strongest signal must be the best signal, right? Well as it turns out, the answer is 'only sometimes.' Consider an antenna that is being blasted by a signal from some interfering source. The new signal will appear stronger, but it's not your signal. Instead of being yours, it could be anything—some other video, wifi, some other form of communication or who knows what? But whatever it is, if you send it to your video screen, you can bet that the result is going to be pretty ugly. Suddenly it's not so clear (pun intended) that RSSI diversity systems are a good solution.
So at Iftron, we decided to rethink the problems and limitations of diversity receivers and the result is a patent pending line of diversity products that combine real-time analysis of signal quality and sync pulse integrity in a novel way to determine which signal is the best. The result is a diversity system that we think is better then the sum of its parts. By uniquely combining the most important factors, our system chooses the best signal more often then either of the afore mentioned methods combined. Yes, there will be those times when neither signal is a good choice, so we can't claim to walk on radio waves, but on average, our novel system turns in performance that can outshine systems costing thousands more. Best of all, we have built this patent pending performance into both our YellowJacket Pro and our new Nano modular diversity products. So whichever you choose, Iftron has you covered.
