One problem with the existing network is data throughput. Large files are transferred across the network regularly, and the transfers take quite a while.

Adding the manufacturing computers will only make this problem worse and result in another problem. Because the ceiling is more than $30$ feet high, there's no easy way to run cables to computers, and providing a secure pathway for cables is next to impossible. Devise a
