Low Power Wireless transmission

Hello everybody.

I was looking today on the internet for low power wireless transmission. For example 6LoWPAN. After reading this, my curiosity on knowing if Arduino is prepared for this increased, so I decided to post this.

I will like to know if someone has never use low power wireless protocols over an Arduino Board, or knows for some company that develops HW integrable with Arduino for this.

Thanks you so much for everyone.
