WiFi is good enough for me. I don't understand why someone wants to fly something that small over a long distances.
not always about distance but rather signal quality. wifi that dji tends to use, which is usually 802.11 G or N has terrible error correction doesnt channel hop, doesn't frequency hop, does not band split, no z-beam or beam forming, uses neighbor friendly CSMA which is what indoor wifi uses and why wifi in tightly packed apartments can suck because hey alrady disobey their own rules and the ones obeying dont speak over others and wait ( reduces link quality), instead of using TDMA which is less friendly to neighboring wifi but CSMA is already terrible so why not, TDMA wifi is friendly to other TDMA based wifi infact can run to side by side on same channel and frequency and not upset things since TDMA is Time Division based vs CSMA it wouldnt work out if you did that
example of how bad wifi is with dji drones: mavic air and the spark for example i could cause them to lag super hard and even disconnect going behind one huge 200+ yr old tree on my property. i had a couple stupid crashes with my mavic air because of the wifi bubbles around houses when i was trying to fly at street level because of the super inconsistent and hard lag that happens |
