"The Evolution of WiFi: From Fighting Microwaves to the Internet of Things"
With the advent of ubiquitous, always connected, personal devices, WiFi has become the the network of choice for a large cross-section of users.  WiFi provides high throughputs to a large number of connected devices at little or zero recurring costs on top of the cost of WAN.  In this talk we look at the evolution of WiFi from its early days in the 2GHz unlicensed spectrum to its present form.  We will also be looking at general principles that are used to design physical-layer air-interface standards.
