• Using thinwire Ethernet, although it is more flexible and easier to use but it has a substantially shorter transmission distance of 185m. In many buildings, the route taken by a thinwire segment is not evident and it can be easy to over-extend it.
2. In the case of TVBCA, as the proposed solution which is the network staff suggests to use a fiber optic backbone to link all three building, for me, the result of this solution is (b. the proposed solution delivers the required results and only one of the two optional desired results), Fiber optics supports the speed of up to 100 mbps and to stay within TVBCA’s budget, the network should also be as inexpensive because Internet service providers supply connections to the Internet along with value added services such as email and Web site hosting. But ISPs also need Internet connectivity themselves, in massive quantities at reasonable prices. The cost of bandwidth is likely the highest business expense for providers. By reducing the cost of their backbone bandwidth supply, service providers can offer more competitively priced broadband connections or improve their bottom line.
3. I think the (a. the proposed solution delivers the required result and both of the optional desired results) because Category 5 specified performance characteristics and test requirements for frequencies of up to 100 MHz. It has a capacity to operate at speeds of up to 100 Mbps. Category 5 cable includes four twisted pairs in a single cable jacket. This use of balanced lines helps preserve a high signal-to-noise ratio despite interference from both external sources and other pairs, this latter form of interference is called crosstalk. It is also easy to install, the cable exists in both stranded and solid conductor forms. The stranded form is more flexible and withstands more bending without breaking and is suited for reliable connections. The solid form is less expensive and makes reliable connections into insulation displacement connectors.
4. As the XYZ case, I think the (b. the proposed solution delivers the required results and the only one of the two optional desired results), field engineers are able to send e-mail to and receive it from employees at the headquarters operation because they are stay connected with each other, they can access to accurate information, it has been viewed as one of the technologies promising the greatest impact on productivity, it not so easy to measure, but still have real benefit for businesses. A happy employee means a happier working environment which means a more productive working environment. Wireless technology use tied to increased flexibility, productivity and time savings. More can be accomplished in less time, leading to a better balance between work and life and a higher level of employee satisfaction. This translates to greater employee loyalty and productivity. All the expected results are possible except for the cheaper cost because using wireless technology needs a bigger amount to install, it is really expensive.
5.
In this case, I think the TVBCA (b. delivers the required result and both of the optional desired solution), the users on one LAN are able to communicate with servers on the other LAN and vice versa and the wireless connection will secure from electronic eavesdropping, the connection can be resistant to electromagnetic interference because using Laser building to building (point to point) networking is a cost effective and secure solution when traditional cable is not an option or just very expensive. Laser Bandwidth is ideal for TVBCA operations looking for a cost effective solution to linking LAN's. This is a wireless installation - all lease line costs are eliminated giving you an incredibly quick return on your investment. Installation costs are minimized as there is no need for the costly installation of cables. Time is saved as there is no need to seek permissions for digging roads or obtaining special licenses. It creates high bandwidth,
optical free space data transmission gives you the same bandwidth and speed of fixed optical fibre. It secures data transmission, free space transmission is one of the safest transmission methods of its type because direct interception is virtually impossible with the concentrated beam and physical placement of the equipment-well above ground level and no instruments such as spectrum analyzers can detect the communication. It has a quick installation, a Wireless Cabling solution is quick and easy to deploy. All solutions are plug_and_play. It ahs an excellent price/performance, wireless cabling systems have outstanding low cost per bit ratios and its flexibility is good, the wireless cabling systems are divided into distance ranges- customers select the system that matches their needs. They can be deployed in a wide variety of network architecture and mesh systems. They can be installed roof to roof, window to window, window to roof or wall to wall.
