This article does do a good job in explaining how it is possible to send quality video through a wi-Fi linkup. The process is quite demanding of resources, it appears. Also, it costs a bit.
One thing that was never mentioned is the degree of signal security, which evidently there is no privacy here on WIFI.

Are that many folks really that lazy, or incompetent, that they are not able to run a bit of cable?
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
