3. Antenna Evaluation
As part of the initial system design, Modular Mining Systems commissions an RF propagation study to
create a custom radio network for your mine. This design specifies
• the number and location of access points
• the type of antenna on each access point
• the azimuth, height, and elevation of each antenna
Antennas are selected and positioned to provide customized coverage so that every part of the active mine
area is serviced by at least two access points.
