The network can be linked from the new building to the existing building by having either fiber or couple of copper wire (twisted pair cable) provided that the new building has installed the switch to actually connect the network. The copper wire that be previously mention is either CAT5 or CAT5e type or any other version. A wireless connection also can be used to link the network. Thus the matter of question here is to which one to be use to link the network. The scenario that be given is there is an old building and a new building and we want to link the network from old to new. Thus, the answer either using fiber optic, copper wired (twisted pair cable) or wireless connection. To discuss further which one to use, there is a few factors that need to be considered when choosing the appropriate cable namely, size, cost, reliability, speed, and electrical interference. From the cost aspect, there is no budget constraint stated in the scenario. If there is no limit to cost, so the fiber optic is the one to be chosen. There are a few advantages of using fiber optic. First, the fiber optic is immune to electromagnetic interference. Meaning, there is no possibility of crosstalk to happen when using fiber optic. Even the thunderous weather will not affect the transmission rate of the fiber optic. Next advantage is the distance capability. Assuming both building situated maybe 200 or 300 meter from each other. According to (ecmag.com, 2000), Cat 5 (or enhanced Cat 5 or Cat 6) has a 90-meter distance limitation, which equals 295 feet. That includes the length of the cable running up and down walls to avoid HVAC systems, fluorescent lights, electrical cables, etc. While for fiber optic, the distance can be up to 2km or more. But if the di...

...he router is connected to the print server and through all 50 PCs directly or wirelessly, they can use the printer and the printer will only print from its respected level. The switch will also connect to the wireless access point (WAP) through the wireless router. Then, the wireless network will act as a backup to connect to the internet when there is a problem with the Ethernet cable of the PCs. Thus, approximately 50 PCs will connect using cable and every PC will have a wireless adapter to allow it to connect wirelessly to the internet if there is problem in the Ethernet cable. The layout is the same for all level. All the routers from each level will connect to the server room in level 2 by using cable rather than wireless. All of the level will be linked together by a central router on level 2 and then connect to the modem and finally to the internet.

    The first issue is that conversation for upgrading existing networks from 1-GE to 10 GE, 40 GE, and 100 GE. For large enterprises that already deploy one solution, it may be difficult and costly to go from 1 to 10 GE. This is because they would be forced to reorganize and get rid of existing calming. Though with the new cabling that would be installed there would, in the end, be less, it would be expensive to reorganize, reframe, reconnect networks and require manpower to do such tasks. Compatibility between these GE’s as well matters as without the latest version is compatible with the previous issues could arise across networks and successfully transferring data. Meaning that there could be a loss of data if there is not a secure connection across networks.

    From the beginning, efficiency and speed in the telecommunications industry has advanced at a fast pace owing to fiber optic technology. In 1979, AT&T filled the telecommunications industry with revolutionary ideas by developing a mode for data transmission using a light, called fiber optic cable. This mode produced a bandwidth of 44.736 Mbps and could multiplex 672 trunk circuits on one fiber alone (Cole, M. 2000). However, this development was merely the start of a huge extension to telecommunications, something that would transform the industry constantly.

    I would suggest conducting a site survey before finalizing a network layout. A site survey will aid with determining where the wireless access points will be placed to give reliable coverage. Interference from other wireless networks could cause connectivity issues and the amount of square footage throughout the office space may also cause issues if the wireless access points are not planned out properly. Once the site survey is concluded any connectivity issues will be addressed and a solid network plan will be put into place (Dean, 2013, p. 366).

It has made such an impact on the way we do business that it has become essential with an ever-growing need for improvement. LANs give an employer the ability to share information between computers with a simple relatively inexpensive system of network cards and software. It also lets the user or users share hardware such as Printers and scanners. The speed of access between the computers is lighting fast because the data has a short distance to cover. In most cases a LAN only occupies one or a group of buildings located next to each other. For larger area need there are several other types of networks such as the Internet.

    G in 1G, 2G, 3G and 4G stands for the “Generation” of the mobile network. Today, mobile operators have started offering 4G services a higher number before the ‘G’ means more power to send out and receive more information and therefore the ability to achieve a higher efficiency through the wireless network. During the time of 1G, radio signals were transmitted in ‘Analogue’ form. 2G networks on the other hand, were based on narrow band digital networks. The 3rd generation of mobile networks has become popular and users access the Internet over devices like mobiles and tablets. This means a 3G network actually allows for more data transmission and therefore the network enables voice and video calling, file transmission, internet surfing, online TV, view high definition videos, play games and much more. 4th Generation mobile networks are believed to provide many value added features.

Now day we can found network almost everywhere. Home, business, public place, Airport, Planes, hospitals, school, train everywhere we can found networking. Therefore, almost every sector of the economy that has affected by wired and wireless technology. Wired network and wireless protect both has security, But in general wireless network is less secure than wired networks. For proper security AP (access point) and its antenna should be right position. Also add a wireless access point or use a wireless router we can connect to network wirelessly.

  • SWOT Analysis of Optical Fiber Corporation

    Fiber optics is a new technology that uses rays of light instead of electricity to transmit information over optical fibers at very high speeds. The optical fibers are usually thin strands of glass that are combined into cables and used to send information and computer data in the form of pulses of light. The optical fibers provide much clearer transmission than conventional copper cable and satellite links. The world market for optical fiber continues to grow rapidly, with shipments increasing 14 percent from an estimated 7.0 million kilometers of fiber in 1990 to approximately 8.0 million in 1991. The demand for multimode fiber is predicted to continue to expand through the mid-1990s, with some market analysts indicating that 15 to 20 percent annual growth over the next three years is reasonable. Strong demand is expected for singlemode and multimode fiber to be used in cables for local area networks, telecommunications, cable television (CATV), and transoceanic fiber-optic systems.
