ZigBee
Technology Overview
ZigBee is a specification for a suite of communications protocols using small, low-power digital radios based on the IEEE 802.15.4 standard for wireless personal area networks. The low power consumption results in battery life cycles of several years or in permanent operation via small solar cells or induction coils, for instance.
Applications
ZigBee is targeted at RF applications that require low data rate, long battery life, and secure networking, such as for sensors in industrial and home automation application.
Rohde & Schwarz Test Solutions
Rohde & Schwarz test and measurement instruments support ZigBee signal generation and analysis with high accuracy. A broad product portfolio from high end to mid range is available for ZigBee testing, including the capability to combine ZigBee measurements with any major mobile radio standard measurement. The application notes provide a detailed description of the generation and analysis of ZigBee signals.
