I am trying to build a "professional" 2 way point to point radio system (like this) to control a RC 1/10 scale car (like this ) using UART, the challenge I am currently facing is finding the right radio modules for the application.
Power 27dbm (0.5w) to 30dbm (1w).
Modulation is FSK or OFDM or QAM or PSK or **SK etc. (encryption is nice option not a must)
Multiple units up to 10 point to point units can be operated at the place with interferance ( i think this is called number of channels )
High throughput 10 to 100 packets per second ( packet about 6 bytes)
Two way communication (High speed switching between send and receive)
I have been investigating several IOT wireless Modules ( LoraWan , SigFox , M-Bus ) and can't find one that works for my application, since most of them don't allow high throughput and are designed to transmit at approximately 1 packet/second which is enough for remote sensing applications. BLE and WIFI lack in power, range and frequency.
The only option I have found so far is Xbee ( maybe i am still reading about ) and TinyMesh
So my questions are :
Is my observation regarding IOT wireless protocols correct?
Can some one guide me to the right protocol for low latency communication I require?
PS: Hopefully this will not be marked as shopping question, I want to understand the protocol or type of network that fits an application :)
EDIT: After Tony's comment about missing specs: cost should be <100$ per Transceiver. Weight and battery power is not an issue as long as it is doesn't consume more than 5W DC (ex: 5v 1A). error correction & detection is a bonus not a requirement. Range is left intentionally Since i mentioned the RF power and frequency.
