Wifi/RC interference

Posted by Adam Day on March 9, 2017 at 10:52am

Hello DIYdrone community,

I am currently getting into research involving interference issues on the 2.4GHz frequencies. I am interested in equipping my drone (arduboat) with a high power (1W) dipole wifi antenna to set up a long distance wlan on a raspberry pi. 

Antenna: https://www.amazon.ca/Alfa-AWUS036H-802-11bWirelessOriginal/dp/B002BFMZR8/ref=sr_1_5?ie=UTF8&qid=1489%20%20016454&sr=8-%20%205&keywords=Alfa+Network+1000mW+High+Power+Wirel%20%20ess+AWUS036H

RC: http://www.frsky-rc.com/product/pro.php?pro_id=105

I have read examples of people using these Alfa wifi antennas on drones, but I have not found any instances where they have encountered interference issues with these specific antennas. 

I am fairly new to this kind of problem, so I was wondering if anyone could offer advice regarding avoiding interference between 2.4 GHz devices.

Thank you,

Adam Day

    would you migrate to 5GHz ? it will avoiding interference from 2.4GHz. it can get 3Km distance over WIFI 5GHz, not sure if it can meet your request.

    Wi-Fi has 14 channels ranging from 2.412 GHz to 2.484 GHz. Access points (smartphones and tablets too) often allow user to manually select certain channel. In my project I'm using Wi-Fi both for sending commands and receiving feedback.

    List of WLAN channels
    WLAN (Wireless local area network) channels are frequently accessed using IEEE 802.11 protocols and are sold mostly under the trademark Wi-Fi. Other…
