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”
