Wireless module?

For one project, I need a wireless module to transmit 2 signals (2 buttons).
Interested in technologies: wi-fi / bluetooth, wi-fi is preferable.
Operating power 3-5 volts, response time < 100ms, operating distance 10-15m.
You also need the minimum size of this module - because. device will be very small.
What are the options?

A friend recently purchased an RFM23. If interested: www.terraelectronica.ru/pdf/HOPERF/RFM23.pdf
It cost about 250 rubles.

why do you need wi-fi and bluetooth modules at all, for the sake of two signals?

Use a radio relay of some sort.
