Because a river divides the administration and student services buildings, the network in the administration building is linked to the network in the student services building only through five obsolete dial-up modem connections in an access server. This region does not have access to DSL or cable modems. What wifi options are available to the institution for connecting these buildings? Which of the above solutions do you prefer?
You're doing projects for two different clients: Thomas Jefferson Community College in Virginia and the Tasty Pelican restaurant in Montreal. You will assist the community college in designing a wireless network for the financial resources team members located in the administration building, as well as determining the best method of connecting the administration building to the student services building. You will assist with the creation of a small private wireless network for the Tasty Pelican restaurant and a public network for the adjacent coffee shop.
XYZ Corp.'s facilities in Nashua, New Hampshire, are two office buildings 400 feet apart, each with its own LAN. To connect the two networks, you plan to dig a trench and lay cable in conduit between the two buildings. You want to use fiber-optic cable, but your budget-conscious facilities manager wants to use 100 Mbps Ethernet over twisted-pair cable. Which of the following reasons can you use to justify fiber-optic cable in this case, and why?
Twisted pair won't span a 400-foot distance.
Fiber-optic cable is cheaper and easier to work with than twisted pair.
Twisted pair is a conductive cable and can therefore carry current based on the difference in ground potential between the two buildings.
Fiber-optic cable leaves more room for growth and future needs for increased bandwidth than twisted pair does.
You're a telecom consultant for a Guyana ISP that wants to enhance bandwidth. Your task is to evaluate current technologies XGS-GPON and NGPON2 and decide which is the best future investment choice. Describe both technology. What makes them different from GPON? When upgrading from GPON to XGS-GPON or NGPON2, what should an ISP consider? Choose one of the two technologies for the firm.
