Wireless Link Characteristics Differences from wired link o decreased signal strength: radio signal attenuates as it propagates through matter (path loss o interference from other sources: standardized wireless network frequencies(e. g, 2.4 GHz) shared by other devices (e.g, phone ) devices motors)interfere as well o multipath propagation: radio signal reflects off objects ground, arriving ad destination at slightly different times make communication across ( even a point to point) wireless link much more"difficult 6: Wireless and Mobile Networks 6-106: Wireless and Mobile Networks 6-10 Wireless Link Characteristics Differences from wired link ….  decreased signal strength: radio signal attenuates as it propagates through matter (path loss)  interference from other sources: standardized wireless network frequencies (e.g., 2.4 GHz) shared by other devices (e.g., phone); devices (motors) interfere as well  multipath propagation: radio signal reflects off objects ground, arriving ad destination at slightly different times …. make communication across (even a point to point) wireless link much more “difficult
