Did anyone manage to explore this further? @hardmavors did it end up working i’m trying to have the radio on my companion computer talking to my GCS and forwarding info to the pixhawk.
I have the same issue where the wifi range is too short.
Firstly wifi are made with computers in mind, that said including companion computer. Data sent between a RC transmitter and receiver is really simple compared to data sent between companion computers and flight controller. Every seconds there are alot of data going thru in between PX4 and ground station. On the other hand there are only a few channel on the RC controller. Which is pretty much more than sufficient for it to do it’s work.
RC controller uses low frequency waves which increases the range and also penetration power. These in terms reduces the speed. Sending so much data over a much slower frequency definitely reduces the speed. In fact in most case, you will see alot of data drop along the way because most data transfer between computers uses UDP.
So unless you are designing and writing your own program to send specific data through the RF that would trim down the amount of data sent and receive, you will definitely see a drop in speed over normal off the shelves operation.
Yes is because most of people use off-the-shelf radio devices comes with their computer or routers, and those devices are not designed for long range communication.
No is because Wifi radio itself in principle, is not designed for long range communication at all. The coding/encoding and modulation scheme used determines it is optimized for maximum data throughput, not distance.
One always need to make a tradeoff, between data rate and range. So if range is the preferred goal, the suggestion would be find another radio other than Wifi.
