[ns] transmit power - does it really control transmission range?

Hi, I am working with a sparsely connected network in a 200m by 200m field. The default transmit power of 0.281838 corresponds to a 250m transmission range. I have a node in the center with this Pt_ and when it sends out packets, all the nodes in the network do not seem to receive it. Why?
