[Tinyos-help] Any info on radiation pattern of telosb?

[Muhammad Azhar]

Hi all,

   How can I find out more info about the radiation patterns of telosb?  
'Coz when I placed the motes "normally" (i.e. with the battery pack touching 
the "ground") versus placing the motes 90 degrees up (i.e. with the long 
edge of the battery pack touching the "ground" through the help of 
blu-tacks), I get somewhat different results, although I've used the same 
program.  Also, I'm wondering if the radiation is affected by the presence 
of metal casings in the building?
   Thanks.

Regards,
Azhar
