Network 帮忙

天空上白云

Identify signaling and transmission media, its physical structure, usage and limitation.

You have been asked to design the entire cabling system for a medical instrument manufacturer’s new central warehouse. The company already has three buildings within two city blocks, and the warehouse will be its fourth building. Currently, the buildings run on separate network, but the company would like to be able to exchange data among them. In addition, the Sales Department would like to hold videoconferences with the Research Department in the next building. Next door, in the warehouse, 50 shipping and packing personnel will be riding up and down on the aisles on forklifts pulling inventory off the shelves on a daily basis. What kind of transmission media would you recommend for each different department of the medical instrument company and why? What type of media would you recommend using to connect the buildings and why?
