      I'm doing this using Ubiquiti. I myself have a wisp and want my uav to hop towers. :) fun stuff.

      I'm a WISP too and we're doing the same thing! Cool!

        What about something in the 3.65 range if you have the license?  I think a Rocket M365 will go out to 10km

      You just have to be a bit careful as only the upper frequencies are licensed for higher power.  The lower block is limited to an EIRP of 1W.  It is only the band 5725–5850 that is licensed for 4W EIRP.

      BTW I did not get to test the 2.4Ghz as I wanted to in the OBC.  It failed on me just before launch.

      I like the look of the Ubiquity WISP as well and may switch to Ubiquity myself.

    Dear all,

    I need to connect and send data (sensors readings) from my RC plane to the PC.

    Usually I would use a SD Card and connect it to my processor (Teensy ARM7) on board and then check saved data on my PC.

    But in this case I should send so much data, that writing in a SD Card would take too much time. So I need to connect ground station and Plane through WiFi.

    Which is the best solution? I heard about XBee Pro but I think that 100m range is not enough.

    There are much more easier solutions or should I try with XBee anyway!??

    Regards

    I have started to experiment with 2.4Ghz however I am still using 2.4 for radio control as well.  If you stay away from N and use G and set the channel to 13 there is plenty of room left for the radio gear to hop.  So far I have not had any problems.

    For long range try the MicroTik gear rather than Ubiquity.  I am ordering the following:

     R11e (Optional 5GHz radio) - http://shop.duxtel.com.au/product_info.php?products_id=292

    Supported_Hardware#4G_LTE_cards

    Ground Station

    Duxbase for 2GHz with 90 degree antenna option, possibly with mobile module added:

    The routers are going to have 3G modems VPN connected and configured to be a fallback link if the wi-fi fails.  RouterOS is a full router operating system and the company has examples and tutorials.

    If you want to pre-calculate some of this this is the best link budget site I have found.

    http://home.deds.nl/~pa0hoo/helix_wifi/linkbudgetcalc/wlan_budgetca... space loss

    If you use MAVProxy you can have all your telemetry down the wi-fi link as well.  You can also do this with a serial to ethernet converter.

    Dont bother wifi routers have a very limited range. Typically after 20-30m you are out of range. That distance is not very practical if you want to fly. I would imagine adding a booster would suck quite a bit of battery.

    Sure have!  Check out this post for some addtitional info:

    I've gone the 5.8 GHz route for video transmission via ubiquiti equipment (wispstation on quad with CPI antenna, and Bullet M5 on ground with 13dbi CP patch).

     

    Here's a video fo my first real field test:

    https://www.youtube.com/watch?v=Z1BdnYNYrqA

     

    I stuck with the 433 3dr radio's for telemetry, as they work fine for me and have more range than my current radio setup anyway..  you can see telemetry data in video as well as realtime signal info from my on-board wireless bridge.

     

    Hope this helps get you going in the right direction!
