...Hospital Networking Project (Week 3) University of Phoenix CMGT 554/IT INFRASTRUCTURE Patton-Fuller Community Hospital Networking Project Today most new building construction is built with new technology and is not as much concerned with the type of budgets that a hospital muse consider in order to redesign a whole new network structure for the purpose of being more optimal and maintaining standards that keep up with advances in new technology. In most cases, a hospital’s network can transition over time with new technology and evolve into meeting the demands it requires to perform effectively. However, upgrading a hospital’s entire network can often be very expensive to implement and sustain. There may be a case where components or parts are no longer being produced to meet current and future demands. In the last several years, changes in healthcare put a demand on hospitals to maintain their networks with new, more efficient solutions that can enhance performance, keep cost low, but most one that is reliable . The Network architecture at Patton-Fuller hospital was designed for each department to rely on information flow between each department. In other words, if the accounting department needed information from the pharmacy or admissions in order to create invoices or insurance billing, it would be rely on those departments to share real time information through the network. It is important for a facility as large as a hospital to have a Networking system that...

...Wired and Wireless Networks ITT Technical Institute Physical Networking – NT1310 11/10/2014 Wired and Wireless Networks The biggest difference between these two types of networks is one uses network cables and one uses radio frequencies. A wired network allows for a faster and more secure connection and can only be used for distances shorter than 2,000 feet. Several other disadvantage of a wired network such as the “need to run cables in difficult environments through walls, floors and ceilings. Cables need to be run from computer to computer and switch to switch. Process can be time consuming. Loose cables likely remain the single most common and annoying source of failure in a wired network.” (PACE University, n.d.) While a wireless network is a very useful and convenient networking device, however these types of networks a lot less secure and transmission speeds can suffer from outside interference. Although wireless networking is a lot more mobile than wired networking the range of the network is usually 150-300 indoors and up to 1000 feet outdoors depending on the terrain. The cost for wired networking has become rather inexpensive. Ethernet cables, hubs and switches are very inexpensive. Broadband routers cost more, but these are optional components of a wired network, and their higher cost is offset by the benefit of easier installation and built-in security features. The primary parts of a wired network are the cables, network adapters, and routers. Wired...

... Wireless Network Plan Deployment Scenario The best deployment scenario for this particular situation would be the infrastructure setup, because this type of networking mode would enable the system to utilize both the wireless components, as well as the wired components. By doing this, the network could utilize the WLAN for most of its networking needs, while still having the capability to merge a LAN into this WLAN design. Deployment Scenario Rationale I decided to go with the infrastructure networking mode due to the physical limitations within the Customer Service Call Center’s floor design, since the infrastructure format would allow the wireless access points to communicate with other wireless access points that are beyond wireless coverage. In addition, for areas that are not considered mobile or require a higher level of security, the use of a wired connection could be used, while still allowing the wireless portion of the network to connect to the wired segment. In other words, it provides a way for the wireless access points to communicate with the rest of the network, which is vital for connecting multiple wireless access points, as well as connecting a WLAN to a LAN.

With this increase, an increase in the number of computers in the household increases and all are dependent upon one Internet source. There are advantages and disadvantages to household network set-ups ( Dubendorf, V. A. (2003) The advantages in the ability to form a home network are numerous. The three main advantages to home networking are: sharing a single Internet connection among multiple computers, sharing files among computers, and using a printer or other device connected to another computer. Another advantage is that less wiring is needed when additional computers have wireless capabilities (Freeze, J. T. 2000). “The addition of wireless capabilities to these gateway devices gives the user the convenience of taking a computer anywhere in the house, and not have to worry about running wires through walls and crawl spaces and attics to connect computers in various parts of the house” .While the student is doing homework, the parent can continue to do work online and access their e-mails. Security issues are the biggest disadvantage to home networking. From , there are at least four types of security issues that exist. The first is...

Overview of wireless networking technology There are various types of wireless network which are wireless Local Area Network (WLAN), Wireless personal Area Network (WPAN), Wireless mesh Network. Wireless networks are convenient in home network, small schools and offices. Wireless network are basically suitable to interconnect cell phones and computers, printers, TVs which helps in easy communication. Wireless network uses radio frequency rather than wire to communicate. Clients unite their gadgets which helps to communicate Wireless access points. The speed is relative to distance between the transmitter and receiver due to the utilization of radio frequency; consequently, the closer the client is to the transmitter the more the speed is. 2. Advantages of wireless networking technology Wireless networking technology gives various benefits to the household and office use, some of these benefits are below:- I. Most of the working class families have few computers which are arranged in various rooms. It is expensive, and time-consuming to introduce cables to a network that are situated in rooms which helps them to impart the broadband communication hence a wireless router resolves the issue. II.
