There seems to be alot of confusion about the different WiFi booster apps. I originally wrote this in another thread but thought it deserved it's own thread to better inform everyone. Also, I did some testing with both apps and those results will be in the second post below. First, Respect to both developers. Both apps work as advertised, I have nothing negative to say about either one and I own both. The two apps are developed separately, they do basically the same thing, and are competing with each other. "FPV Booster for Vision+" (from PVFlyer) is $8.99 on iOS, $8.77 on Android. It's an automatic WiFi signal booster with no additional features yet. https://itunes.apple.com/us/app/fpv-boo ... 13138?mt=8 https://play.google.com/store/apps/deta ... ster&hl=en FPV Booster is one touch, one button, no bells and whistles. You tap the button that says Boost Up! and you're done. The author claims that in addition to simply increasing signal strength it "equips with an interference control algorithm. It boosts extra 50% FPV range with the same Wifi power ... especially in urban area." What it appears to do is set the WiFi TX power at the optimum values for the best possible range. Not necessarily the maximum values. See below for testing results. "Vision+ Utility" (from ocatcr) is $2.99 on iOS, $11.60 on Android. It's a WiFi signal booster with added features that gives you manual control of TX power levels. It allows you to control the TX power on the Phantom and the Range Extender individually. https://itunes.apple.com/us/app/vision+ ... 18291?mt=8 https://play.google.com/store/apps/deta ... ypro&hl=en It's not as simple to use since you have to select the range extender or Phantom, one at a time, and manually choose what power level you want to set it to from 4bBm to 20dBm It also allows you to add encryption to your range extender link to keep out other people. The Android version now has data logging so it can record your flight telemetry and they've just added CH7 pitch control. The iOS version has yet to be updated with the data logging feature or pitch control. Maybe next week. And note the price difference above. I'm sure it will be a new (pro) version on iOS that you'll have to buy again at a higher price. For a "do it yourself" method of boosting WiFi power, check out this thread and you'll see what these apps are doing. viewtopic.php?f=27&t=17704 See below for a simple test I ran using a WiFi scanner to compare power output and channel information.
