[Tinyos-help] Synchronization and "high data rate" on radio?

[Henric Kärnhall]

Hi

I have posted these questions a few times but never got any clear
answers. I would be pleased if someone could give me some answers this time.

1. Why does netsync require "lowpower" mode? And what does it actually
mean to compile with the lowpower flag?
2. Is it possible to send data with high data rate on the radio when
using synchronization with netsync? (high data rate = same data rate as
without using netsync)
3. Is there any other way to get a synchronized global time without
using netsync?
