Review Questions • Explain how advances in MEMS have contributed to the development of WSNs • List and briefly explain the purpose of four building blocks of a Mote. • List and briefly explain the function of the OS on a WSN node • Name and briefly explain a technological, scientific, and cultural development that have contributed to the development of WSNs • What is Tiny. OS? • Explain (to a non-expert) what is a mote The University of Iowa. Copyright© 2005 3 A. Kruger

ISM Bands • The industrial, scientific, and medical (ISM) radio bands • Originally internationally for non-commercial use of RF. Limitations on data. • Today, commercial, Wireless LAN, Bluetooth, IEEE 802. xx networks. No limitations on data. • Bands – 900 MHz band (33. 3 cm wavelength) – 2. 4 GHz band (12. 2 cm wavelength) – 5. 8 GHz band (5. 2 cm wavelength) • License Free, but NOT unregulated • Often Spread Spectrum, but need not be The University of Iowa.
