How much area does the WiFi radio on Crux cover?

Crux has a circular internal WiFi radio antenna. In our lab tests, and customer deployments, the coverage ranges between 20 - 30 meters spherical radius (laterally - on the same floor plate and vertically - one floor above and below). However, wireless signal can vary drastically based on construction and use of glass and metal. Typically scaling beyond one floor above or below, or 10,000 square feet of horizontal space will require additional Wireless Repeaters or Access Points. Crux pairs well with all commercially available routers (for example, D-Link DIR-816 which is an inexpensive router that works as repeater and retails for $40-50) that works well as a repeater that provides good ground coverage and well suited for this use.
