Anybody bold enough to try this A7105-500m wireless transceiver Antenna / nRF24L01 + / CC2500/SI4432/CC2530?
It look like this is the solution to solve issues with coverage and the use of repeaters...
@marceltrapman that's not nrf24 based; they just use it as a keyword to attract eBay buyers!
Search for "nRF24L01 1000m" and you see quite some matches.
Is it possible? Yes, using the right antenna's and line of sight it is possible but real world, no way.
