Android device controlling Arduino via Wi-Fi

hello everyone!

ok, have more of hw question. wondering possible control arduino project via wi-fi android device without connecting both devices local network?

i searching around arduino forum , global web, found projects included:
arduino -> bluetooth module -> , direct connection android device via bluetooth
arduino -> wifi/ethernet shield -> connected local network -> communicating android device, connected same local network, via wi-fi

so there wi-fi module can communicate android device without connecting network? or still unexplored ground?

ok maybe i'm naïve thinking replace rc receiver arduino , rc transmitter android device. amazing see response of people example @ rc boat competition competitors around have sorts of expensive rc transmitters while use smart phone. 

now turn write opinion or thought this, because want know if i'm 1 dumb replace powerful rc transmitters.

probably not, since sole purpose of wifi enable participate in network. first problem find android app enables bypass network.

while bluetooth typically 10m, can more powerful types 100m may suitable.
