Besides 2.4G frequency and bi-directional Wifi, supported modulation is a key consideration. P2V/V+ Wifi is on 802.11N using OFDM modulation. 2.4G Wifi booster does NOT always mean supporting 802.11N & OFDM modulation.
I sent the simple following question to DJI support:
"How did DJI obtain longer FPV distances of the P2V+ over the P2V?"

Dear Sir,
More Powerful Range Extender

I doubt about the response.
P2V repeater (RE500) TX power is about 21 dBm (125mW) measured by multiple forum members with RF power meter, though it's advertised <=17 dBm (50mW). Vision+ repeater (RE700) TX power is advertised with 20 dBm (100mW), and I guess it's about the same as advertised per my preliminary observation (by Wifi Analyzer app). I may open it up and measure the RF power soon. Stock Vision+ has double the FPV range than P2V, and this would require 4X TX power to achieve such range if using the same technology. Obviously, the DJI response "More Powerful Range Extender" is NOT telling the truth, or maybe "Powerful" means using more advanced technology instead of higher RF power.
On the other hand, P2V camera Wifi TX power is about 100-125mW per my measurement, while Vision+ Wifi is only 10-20mW (per my estimate). How come Vision+ aircraft has only 10-20% Wifi TX power of P2V but double the FPV range, while both repeaters (RE500 & RE700) have about the same TX power??
The truth is DJI adopting a new communication protocol (similar to WiMAX or LTE) on Vision+. I guess such new protocol substantially lower interference & improve effective S/N ratio.
in other words?
should I buy a new range extender? and problem solved?
were, and how to know if it will have the extended range needed.

Considering the cost of the range extenders, I'd first pose that question directly to DJI Support. Call them up!
already pop the question to dji support.
ill post once they answer me.
im disappointed that got the phantom vision 2 and the day I got it the came up with vision 2 +
my face was wtf. but ok. lets see how we get that range extender.
or if we have a nice setting that helps.
please keep posting your tries to see which one is the best set up

thanks Tony. THIS is what I've been suggesting all along, but they dont listen. :lol:

Dear Sir,
The vision+ range extender doesn't compatible with vision.
Best Regards
