Typical Performance Characteristics

All TIMEn synchronization error testing was performed with the hop-1 mote inside a temperature chamber. Timing errors

due to temperature changes and temperature differences both between the AP and this mote and between this mote and its

descendents therefore propagated down through the network. The synchronization of the hop-3 and hop-5 motes to the AP

was then affected by the temperature ramps even though they were at room temperature. For 2°C/min. testing the temperature

chamber was cycled between -40°C and 85°C at this rate for 24 hours. For 8°C/min. testing, the temperature chamber was

rapidly cycled between 85°C and about 45°C for 8 hours, followed by rapid cycling between -5°C and about 45°C for 8

hours, and lastly, rapid cycling between -40°C and about 15°C for 8 hours..
