Implementing a New Wide Secure Wireless Network at Brigham Young University Hawaii

Patton – Fuller community hospital’s network system consist of two major parts, the first part is the executive part that connects the hospitals executive management, human resources department, operations, IT and data center, etc., the first network is connected using a 1000base-T Gigabyte network connection that uses a typical Cat6 cabling (Apollo Group Inc., 2008), the second major part of the network connects the departments of radiology, operating room, wards, ICU’s, etc. using a 1000base F fiber optic based connection, this connection is a

The devices that need to connect are workstations, wireless access points, security cameras, servers, phones and printers, with enough available bandwidth between buildings and devices. The wireless network itself will be able to handle multiple devices and there needs to be enough coverage throughout the campus, including the outdoors. Separate wireless network will need to be establish to ensure that guest traffic does not affect church network traffic.

You are in charge of the security of information in a research lab. Most of the information is stored in electronic format on the LAN. The researchers can also access these files from their homes. The computers in the lab are also connected to the Internet. The current access is provided to Internet via a combination router-firewall. The entire network resides behind this single firewall-router configuration. It is quite important to maintain the confidentiality of the information, although the lab has limited funds allocated for security. There are 8 workers that use the network connections.

City Hall will host the Layer 3 routers and switches, in addition point to point source radios. Connecting the 9 schools and 9 buildings using the PTP radios and then distributed with simple Layer 2 switches to wireless access points located inside each of the buildings.

There are various types of equipment that the company should look for when considering this network. The first item to look at when considering equipment is the Operating system and software that we would need. Next, the group took into consideration the type of server the company needs to make this network a reality. Another thing that we looked at is the possibility of having ThinClients over regular desktops for all workstations. Of course, it was taken into consideration that some employees would not want ThinClients. So, we show the type of tower we plan to place into those spaces, along with any peripheral device for both. Then, we will look at the network devices that will go into each building that include switches, routers, repeaters, hubs, and wireless access points. Finally, the group will note guidelines for choosing a local ISP at each site. Each Item outlined helps to build a network based on the specifications given by the company.

The new structure has been given a grant to make its network state of the art by making it a fiber optic network. The topics of discussion that will be mentioned in this paper are the hardware that will be necessary for the inside and outside of the building and how we would expand the fiber to an adjacent building if it is built. Another topic to be discussed will be describing the safety procedures that will be following during the installation.

After observing the option between Free Space Optics and Radio Frequency wireless solutions I have opted to recommend the radio frequency option because that is the option that suits the cities needs the best. Each building will have wireless Ethernet Bridge that can act as either a leaf or branch. I would suggest configuring each or at least two buildings to act as a branch allowing some form of redundancy.

WiMAX can transmit speeds up to 50km at 280mbps, and provides options for use in point to point and multipoint configurations.

The best network design to ensure the security of Corporation Techs internal access while retaining public Web site availability consists of several layers of defense in order to protect the corporation’s data and provide accessibility to employees and the public.

The proposed network is designed to serve DesignIT which consist 56’x36’ office space, 4 cubicles, 1 office, 1 server room, 1 receptionist desk and 1 conference room.

Main Building – will require 7 computer stations with the most recent version of Operating System to ensure compatibility and networking capabilities between each stations and the ability to communicate between the two locations. They will require three servers, one for web hosting, one for database management and one for emergency failure of any one server. These stations should be networked to communicate with one another for proper data connection especially in the event of any one computer station crashing. Each work station will need to be linked to each server for web hosting and data backup. The cabling used for inside the main building should be 100Base TX cat 5 UTP, for Wi-Fi and WLAN with guest access that is highly secure and reliable, we recommend a device that is capable of supporting up to 15 different users with 450 Mbps. There needs to be 4 printer services in this building. Printer 1 should have

5. Administration departments spread over another 10 buildings. LAN IP’s: Building 1 (128.100.17.x), Building 2 (128.100.18.x), Building 3 (128.100.19.x), Building 4 (128.100.20.x), Building 5 (128.100.21.x), Building 6 (128.100.22.x), Building 7 (128.100.23.x), Building 8 (128.100.24.x), Building 9 (128.100.25.x), and Building 10 (128.100.26.x). Router IP’s will be respectively as follows: (128.100.254.11), (128.100.254.12), (128.100.254.13), (128.100.254.14), (128.100.254.15), (128.100.254.16), (128.100.254.17), (128.100.254.18),

From my research it has been highly recommended that a CAT5e and or CAT 6 UTP cable be used with a star topology and or mesh topology be used for the LAN line, reasons for this being the low cost and the speed of over 500 to 1000 Mbps on the network. The network signal will stretch across the building and connect all wired devices but the signal would not be as strong in some areas, to combat this 75 micron fiber optic will be used to connect to the IT closet in each floor. The micron optic cable is said to deliver 1000 Mbps across more than 100 meters before the signal connection starts changing for the worse, and this is more than what we need. For the wireless network we will be looking for speeds of 100 to 300Mbps. When it comes to security

The proposed network is designed for the UMUC new building in Rockville. This new building will have some administrative offices, lecture rooms, library, and computer labs with an open Wi-Fi. This new building will have total six computer labs that will be used for instruction. Each of these labs will have 25 computers, 23 student computers and one instructor computer, one server in the closet and in addition to the six computer labs, there will also be a Student Computer Lab that will provide computer access to students for doing their own purpose like homework. In Student Computer Lab there will be 30 computers and a server in the closet. There will be 10 computers for student’s use and 5 computers for Library staff in the library so they can access to the library resources for staff use, with the exception of the admissions office, which will have five computers. There will be six class room which will have a computer for instructor’s use. Finally, there will be 7 offices in the building and each of these offices will have one computer. There will be two server rooms, one on the first floor and another one on the second floor. There should be at least 3 separate networks: Administrative, Instructional, and Public. All staff-accessed computers will be on the

Topology: The current network was able to mix different speeds to match departmental needs. The physical topology in use is linear bus topology which also translates to a logical bus topology. The cable in use being Thicknet gives extended length allowance which is 500meters for a given segment and 2500 meters total cable
