Dear All , I Read Many Comments on Archive and Ns Coding: I know that a Cross Over Paramete exist For differing Between Short and Long Distance Propagation Model on Using Two-RayGround Model. If Below of "Cd" Use Friis Equation but on higher than It uses Main Two-ray Ground Equation. The packet

Hi All, I have Static WLAN 802.11b Scenario. I used TwoRayGround For Propagation. I want to Calculate Good Positioning of My Nodes. In Spec Tec of Real WLAN 802.11b Card we Have Receiver Sensivity And Power Output. I knew that Power output Equal with Pt_. But How can I relate Between other param
