Co to jest Zigbee Protocol?

Zigbee is a wireless communication standard built one IEEE 802.15.4 physical and MAC layer specification. It operates primarily in the 2.4 GHz ISM band (worldwide), witch additional sub- GHz bands (868 MHz in Europe, 915 MHz in the US) for reduced interference andd longer range. The protocol supports dates of 20- 250 kbps - modest compare to Wi- Fi, but more thatn thelent for sensor readings, switch comperts, and status, and statupes tyl tyl in home automation.

  • Set your Wi- Fi channel to 1, 6, or 11 (non-coverlapping) and avoid channel 6 if possible (Zigbee channels 15- 20 often overlap with Wi- Fi 1- 6).
  • Usie Zigbee channels 25 or 26 if your country permits, as these are les crowded.

This gives it longer range and less interference frem Wi- Fi, but at lower data rates (40- 100 kbps) ingimer light.
