Hi,

In an outdoor environment, I put one MicaZ mote A about 1.5m high above the
ground. I use another MicaZ+MIB520 to receive data transmitted from MicaZ A.

I am using TinyOS 2.x and I do set the maximum transmission range of A
(CFLAGS +=-DCC2420_DEF_RFPOWER=30). However, the transmission range of MicaZ
A is only about 20 meters. In the specification of MicaZ, it says the
outdoor range could be 75m to 100m.

How could I achieve this 75m transmission range? Please share the
experience.

Many thanks,

Gary
