The PHY 1 was established for outdoor application and works from 11.67 kbit/s to 267.6 kbit/s. The PHY 2 layer permits reaching data rates from 1.25 Mbit/s to 96 Mbit/s. The PHY 3 is used for many emissions sources with a particular modulation method called color shift keying (CSK). PHY III can deliver rates from 12 Mbit/s to 96 Mbit/s. [40]
Qi (/ tʃ iː / CHEE) is an open standard for inductive charging developed by the Wireless Power Consortium.It allows compatible devices, such as smartphones, to receive power when placed on a Qi charger, which can be effective over distances up to 4 cm (1.6 in). [1]
