A smart meter, a thermostat, a solar inverter and an EV charger all talk to each other, with no cables. In Episode 5 we cut the cable: we meet the wireless members of the IEEE 802 family, take a close look at Wi-Fi, and follow one meter reading from a home all the way to the control center. 📄 FREE STUDY NOTES (PDF): https://drive.google.com/file/d/1hXL9... In this video you'll learn: ✅ Range vs data rate: where each 802 technology fits ✅ Bluetooth (802.15.1) and Bluetooth Low Energy ✅ IEEE 802.15.4 and what ZigBee, Thread and 6LoWPAN add on top ✅ 802.15.4g Smart Utility Networks and the Wi-SUN FAN mesh for smart meters ✅ Wi-Fi HaLow (802.11ah) and Wi-Fi mesh (802.11s) ✅ WiMAX (802.16) scheduling vs Wi-Fi contention, and WRAN (802.22) in TV white space ✅ Wi-Fi building blocks: station, access point, BSS, BSSID, SSID, ESS, distribution system, roaming ✅ The 2.4, 5, 6 and 60 GHz bands, sub-1 GHz HaLow, and channel bonding ✅ CSMA/CA: DIFS, random backoff, SIFS and ACK, the hidden node problem and RTS/CTS ✅ Wi-Fi 4 to Wi-Fi 8, plus OFDM, MIMO, MU-MIMO, OFDMA, beamforming and multi-link operation ✅ WEP, WPA, WPA2 and WPA3, Personal vs Enterprise (802.1X) ✅ Where wireless fits in the grid, Ethernet vs Wi-Fi, and the HAN, NAN and WAN journey of one reading Solved problems: 🔹 Why do engineers use only channels 1, 6 and 11 on 2.4 GHz? 🔹 How long does a 450 MB firmware download take over shared Wi-Fi, and how does it compare with a 1 Gb/s Ethernet cable?
