21. In this paper, the term "polling" is used to indicate a CO listening to and/or interrogating subscribers.
22. Our wavelength-optimized photovoltaic converter has a high conversion efficiency of up to 50 % depending on illumination power and load [1.3]. For low optical input powers, a pin-photodiode with very small saturation current is optimum.
23. Mixed signal microcontroller, Texas Instruments MSP430-family. At 3.6 V and in low-power mode LPM3-VLO ("sleep mode", internal inaccurate clock active) we measured a supply current of 0.5 μA, in LPM3-LFXT1 ("snooze mode", external accurate quartz clock active) it was 1 μA. Further modes are memory retention mode LPM4 (0.1 μA) and active mode (390 μA). An interrupt event can wake up the device from any of the low-power modes, service the request, and restore back to the low-power mode on return from the interrupt program.
