ImmersionRC made a surprise and showed a new RC radio link called Ghost. And trust me, this thing, if it will get adopted, will revolutionize the FPV we know today. Why? Because it's a combination of two worlds: 2.4GHz band and LoRa technology known from TBS Crossfire and FrSky R9 systems. All the details of Ghost are not public yet, but based on the manual, specification, and other external sources, I've been able to compile a list of essential things about IRC Ghost.
It is a LoRa system
ImmersionRC Ghost works in 2.4GHz band, but it's into the same technology as existing 2.4GHz radios from FrSky, Spectrum or FlySky. Instead of "traditional" FSK only RF chipsets like Texas Instruments CC2500, it uses Semtech SX1280/SX1281 (I have no solid proof which one exactly but I suspect it's a SX1281) that support both FSK modulation and LoRa. Yes, the same LoRa technology that stands behind TBS Crossfire and FrSky R9.
I will not go in details what LoRa is, but it's super clever Chirp Spread Spectrum modulation that has high sensitivity and can pick up signals that are below Noise Floor. So yes, it can do Long Range for dozens of miles, and you will sooner lose FPV feed than 2.4GHz LoRa signal!
