ZigBee is a wireless communication technology developed as an extension to WLAN (IEEE 802.11) and Bluetooth (IEEE 802.15.1). Its purpose is to connect sensors and household devices over short distances ranging from 10 to 100 meters. This standard specifically focuses on wireless personal area networks with low data rates. The frequency range is 2.4 GHz, similar to WLAN and Bluetooth.
The Additional Technical Contract Conditions and Guidelines for the Construction of Asphalt Traffic Area Surfaces, known as ZTV-Asphalt-StB, have been established by the Research Society for Roads and Transportation (FGSV), specifically the "Asphalt Construction Methods" working group.
