Explanation of terms in a Bluetooth project datasheet

[qiushidaren]

Hi all, there are some features below from CSR’s Datasheet:
1.Full Speed Bluetooth Operation with Full Piconet Support
2.Scatterment Support
3.Dual UART Ports to 4Mbits/s
4.VFBGA Package or WLCSP
5.Support for 802.11 Coexistence
6.RoHS Compliant
But, you know, I am just a newbie in this field, and I am going to do a project about Bluetooth, so I want to know what do the acronyms above stand for.
1.What does “Full Piconet” mean?
2.What does “Scatterment” mean?
3.What does “Dual UART” mean?
4.What does “802.11” mean?
5.What does “RoHS” mean?

Your explanations will be highly appreciated! Thank you in advance!
