The standard uses analog transmission (Wifi) whereas Lightbridge uses digital encoding which makes it more reliable and allows higher data rates at further distances.Both have the same camera. Both say they can do 720p video downlink. The P3S has a range of 1km and the P2A with Lightbridge has a range of 3.5km.
Is range the biggest difference?
Also look at the radio control units.Is range the biggest difference?
What? I thought both Wifi and Lightbridge are the same, using embedded digital data transferred over analog waveform?The standard uses analog transmission (Wifi) whereas Lightbridge uses digital encoding which makes it more reliable and allows higher data rates at further distances.
No, these are different technologies, but both use 2.4Ghz. Both use digital technology, however Lightbridge is a one way transmission of video, like a digital TV broadcast. In addition to the video broadcast down to the ground, a separate 2.4Ghz RC digital signal goes up to the craft to control navigation.What?

Naw.....you're normal.$349. Really. I must have been an idiot to buy my Vision for $607 last August.

Also, the P3A/P has Glonass & GPS, the P3S has only GPS.
Thanks for giving more detail explanation. I am just a bit surprised when rene van der meer says wifi is analog transmission while Lightbridge is digital encoded. I thought his statement is not accurate because wifi is also digitally encoded too, just that Lightbridge is DJI's proprietary technology for better and longer range signal transmission.No, these are different technologies, but both use 2.4Ghz.

Yes, me too! I'm so sold on the "broadcast" architecture of Lightbridge that I won't buy anything else either, until someone copies the idea and truly competes with DJI. Right now nobody competes with DJI's Lightbridge. I'm wondering how long that's going to last.I will NEVER buy a wifi drone again. Too unreliable and problem prone!
Noodle, you are right. Both use digital transmission, but Lightbridge is a down-link only especially designed for digital video transmission and is less susceptible for interference with other Wifi sources.
