History of Cumputers

WiFi Originated in Hawaii

1979

The early predecessor of WiFi was launched in Hawaii in 1979. The ALOHAnet was a computer networking system that allowed the first public demonstration of a wireless packet data network.

WaveLAN

Jan 18, 1991

WaveLAN was a brand name for a family of wireless networking technology. The WaveLAN name debuted on the market in 1988 and was in use into the mid-1990s. WaveLAN laid the important foundation for the formation of IEEE 802.11 working group and the resultant creation of Wi-Fi. It has been used on two different families of wireless technology.

First 802.11 spec released

Jan 18, 1997

Released in September 1999, it's most likely that your first home router was 802.11b, which operates in the 2.4GHz frequency and provides a data rate up to 11 Mbps. Interestingly, 802.11a products hit the market before 802.11a, which was approved at the same time but didn't hit the market until later.

WECA

1999

Alliance & Interbrand coin the term “WiFi”, referring 2002 to the 802.11 standard. Operators around the world start offering WiFi along with classic cable connectivity.

Wi-Fi Alliance formed

Jan 10, 1999

The Wi-Fi Alliance, is an organization that promotes Wi-Fi technology and certifies Wi-Fi products, if they meet certain interoperability standards.

First chipset

Aug 10, 1999

The ESP8266 is a low-cost Wi-Fi microchip with full TCP/IP stack and microcontroller capability produced by Shanghai-based Chinese manufacturer Espressif Systems.
The ESP8285 is an ESP8266 with 1 MiB of built-in flash, allowing for single-chip devices capable of connecting to Wi-Fi.
The successor to these microcontroller chips is the ESP32.

802.11a/b

Sep 22, 1999

IEEE 802.11 is a set of media access control and physical layer specifications for implementing wireless local area network computer communication in the 900 MHz and 2.4, 3.6, 5, and 60 GHz frequency bands. They are the world's most widely used wireless computer networking standards, used in most home and office networks to allow laptops, printers, and smartphones to talk to each other and access the Internet without connecting wires.

802.11g

Jun 23, 2003

IEEE 802.11g was developed in 2003 as an 802.11b extension. Increase the transmission speed of up to 54 Mb / s using the same 2.4 GHz bandwidth used in the 802.11b standard.

First WIFI devices

2004

First WiFi devices, such as PDAs, cell- phones and TVs, hit the market.
