The system at the university begins in an office. The office contains a fiber interface, a cheap gateway/router/AP combo unit, and a modem. These items must be powered by a solar system.
We might be able to replace the cheap gateway/router/AP combo unit. Replacing this unit involves reconfiguring mission critical computers which depend on the existing wired and wireless networks to work correctly. We may need to continue piggybacking on top of the existing equipment like we do today.
