    2 wifi devices at same time?

    For iOS, just use AirPlay with any AirPlay receiver (I used Reflector). For Android (rooted) BBQScreen will do the same thing.

    2 wifi devices at same time?

    I've connected my MacBook to the Phantom WiFi network and shared my iPhone screen to the MacBook via AirPlay (with the Mac/PC app called "Reflector"). This works very well and even allowed my live video feed to be connected to a 55" LCD screen via the HDMI out of my MacBook. I was in the...

    GPS signal booster

    Are you able to get a good sat lock on your phone when this problem occurs? If you're on Android, an app called "GPS Status" will show you lots of info. Perhaps someone in close proximity to you is using an illegal GPS jammer, most likely installed in their car? :?:

    P2 Vision video range extender 2W - 40$ free shipping

    This infographic might help to explain things. http://cdn.xirrus.com/pdf/wifi-demystified/Documents_Posters_Range_Plotter For the most part, you can ignore the multipath square, as MIMO in 802.11n pretty much solves this and we really shouldn't experience any multipath flying outdoors while...

    P2 Vision video range extender 2W - 40$ free shipping

    I suspect that the WiFi onboard the P2V+ aircraft also outputs 20dBm. With WiFi, you get the best results matching EIRP (antenna gain + tx output) at both ends. The underlying protocols in WiFi require a bidirectional communications link, if one side or the other has more power, it doesn't...

    P2 Vision video range extender 2W - 40$ free shipping

    100% correct! While I don't have 40 years of ham radio experience, I have been a licensed ham radio operator for 19 years and full-time employment includes working on both outdoor wireless mesh networks and indoor enterprise wifi networks.

    P2 Vision video range extender 2W - 40$ free shipping

    Ummm, no! Amplifier the TX side of the ground equipment does NOTHING to help receive information from the aircraft. In fact, it probably introduces loss on the RX side of the ground equipment. I suppose it is possible that the introduced line and connector losses can be addressed with a better...

    P2 Vision video range extender 2W - 40$ free shipping

    Increasing the power output on ground equipment probably won't help much. WiFi is bi-directional, but most of the data is coming from the WiFi module in the P2V camera. That is where you would want an amplifier.

    More powerfull repeater?

    Yes, this antenna is perfect for the repeater. However, it also happens to be a great antenna to use for the controller/transmitter. If you use both ports for 2.4GHz only from the WiFi repeater, you won't have any ports left for the transmitter. Using a duplexer/combiner, use a single antenna...

    More powerfull repeater?

    This little bugger is the right price, size, and specs. Only bad thing is there are only two antenna ports, so if you want to use it with the 5.8GHz transmitter too, we need to either use duplexer to combine output from the 5.8GHz transmitter with one of the WiFi transceivers, or give up...

    More powerfull repeater?

    The problem with omni-direction antennas is they don't reduce the noise floor from the areas around you (behind and to the side). Directional antennas work so well because their receive is directional as well, focusing your TX and your RX in a given direction. With RF, the range is determined...

    More powerfull repeater?

    Something like this would be almost perfect... 6dBi gain, spatial diversity, dual band 2.4/5.8, and reasonable beam widths of 82 horizontal and 72 vertical. It could be used for both the control link and the video link. Would just like a little more gain (like 9dBi instead of 6dBi)...

    More powerfull repeater?

    Assuming the repeater is MIMO (which it should be), you're giving up some potential signal gains by not leveraging both antenna ports (spatial diversity). I'm not sure about the math to calculate it, but I wouldn't be surprised by a 3db improvement, or more, with spatial diversity.

    Updated manual posted today - Nov 18, 2013

    I noticed that an updated version of the manual was posted today. http://download.dji-innovations.com/downloads/phantom-2-vision/en/Phantom_2_Vision_User_Manual_v1.04_en.pdf http://www.dji.com/download/phantom-2-vision-downloads/

    Reduced RC and Wifi range AFTER Tx firmware upgrade ?

    Are you still getting two beeps when you turn your controller on? Might want to try switching back to CE compliance mode (single beep at power on) and then back to FCC compliance mode.
