CYFI is Reliable: Active Link Management Part 1

A CyFi Network operates in a quiet channel to ensure the hub can receive packets from the nodes

1

A Wi-Fi network starts to interfere

The hub will immediatelydetect the noisy environment

2

A CyFi Network will hunt for aclean channel and settle there

3

Network resumes with successful transmissions

CYFI is Power-Efficient: Low Power Consumption

Data Rates dynamically switch between 1 Mbps and 250 Kbps depending on the environment to maximize sleep time and reduce power consumption

Should a node detect that its power output is excessive, it will dynamically reduce its power output to conserve power
