Objectives
Determine correlation between RSSI
and distance.
Find relationship between packet loss
and RSSI.
Examine the effect of delay upon
distance.
Testing Method
TELNET into one of the non-gateway
nodes and placed it close to the
gateway.
Pinged the other non-gateway node,
varying the distance by using the fact
that 1 tile = 1 foot.
RSSI vs. Distance
Packet Loss vs. RSSI
Delay vs. Feet
Lessons Learned
Obstacles can cause significant
interference (loss in RSSI)
Distance does not greatly impact delay
Do not see significant packet loss until
RSSI approaches -92dBm
RSSI is not highly correlated with
distance
