How long is the Transmission Range?
top ZigBee relies on the basic 802.15.4 standard to establish radio performance. As a short-range wireless standard, 802.15.4 doesnt try to compete with high-powered transmitters but instead excels in the ultra-long battery life and low transmitter power. The standard specifies transmitter output power at a nominal 3 dBm (0.5 mW), with the upper limit controlled by the regulatory agencies of the region in which the sensor is used. At 3 dBm output, single-hop ranges of 10 to more than 100 m are reasonable, depending on the environment, antenna, and operating frequency band. Instead of pure power, ZigBee augments the basic 802.15.4 simple transmitter and protocol with an extensible, sophisticated network function that allows multi-hop and flexible routing, providing communication ranges that can exceed the basic single-hop. Indeed, depending on the data latency requirements, you can practically create networks that use dozens of hops, with cumulative ranges in the hundreds to thousands o
