With the news that WiFi will get a new version next year, y que se llamará WiFi 6, I thought I’d knock up a little guide to the previous versions of WiFi that we’ve had
| Standard | Nombre | Máxima velocidad | Frequency | Año | Notas |
|---|---|---|---|---|---|
| 802.11b | Wi-Fi 1 | 11 Mbps | 2.4GHz | 1999 | |
| 802.11a | Wi-Fi 2 | 54 Mbps | 5GHz | 1999 | |
| 802.11g | Wi-Fi 3 | 54 Mbps | 2.4GHz | 2003 | |
| 802.11n | Wi-Fi 4 | 600 Mbps (150 Mbps por flujo) | 2.4GHz o 5 GHz | 2009 | Use of MIMO and multiple antennas up to 4 corrientes |
| 802.11C.A | Wi-Fi 5 | 600 Mbps (2.4GHz) + 2,167Mbps (5GHz) | 2.4GHz y 5 GHz | 2013 | MU-MIMO intorduced. Hasta 8 MIMO arroyos, wider channels, and 256QAM modulation. Typical speeds of around 500 Mbps — 1 Gbps |
| 802.11hacha | Wi-Fi 6 | ~ 11 Gbps | 2.4GHz y 5 GHz | 2019 | Utiliza 1024QAM y OFDMA. Uses lots of tweaks to increase efficiency of spectrum usage, resulting in much higher real world data rates |
