Will the Arduino's low clock speed limit wireless transmission frequencies that are higher than the clock speed of the Arduino?

The frequency of a (wireless) radio is its carrier frequency. The data stream is carried on it by modulating that carrier wave in some way: by frequency-shifting, for example. A given processor could ...

Multiple Wireless Sensors to an Arduino

I would recommend the nRF24L01. You don't need one pipe per node - just one pipe. Each pipe is effectively an address that a node responds to - having multiple pipes means you can have multiple ...
