I have one doubt about tmote batteries duration. I'm using tmote sky
with 2 AA 1500 mhA batteries. If i not use any LPL on cc2420 the rx
consumption would be about 18.8m A. So the  energy in one second would be 
E = 3V · 18.8 mA · 1 s = 56.4 mJ

I have read the joe paper about b-mac where says that 
t(s )= Cbatt · V·60 · 60 / E

It gives me about 6 days of bateries duration. Would it be right? I
suposse that radio is always in rx mode waiting... Am I wrong? 
thanks a lot
