...ROCKET FIBER SIENA HEIGHTS UNIVERSITY Strategic Mgmt. of Innovation (OA) Instructor: Gregory Smith April 1, 2016 There is a large number of high speed internet companies that offer a large range of services and promise customers that they offer the fastest online speeds. Comcast is considered one of the fastest and the most expensive of the online services. They started offering their services in a bundle package of cable, phone, internet and home security to receive a maximum profit from consumers. WOW (Wide Open West) uses Comcast cable network but, charges its customer’s a fraction of the price and still gains a profit by doing so. The second largest internet provider is AT&T, they have a long history of always servicing residential customer. Now, with the introduction of U-verse a few years ago; they are one of the top giants in the cable television, internet, phone and home security industry. The newest internet service provider to enter this crowded field is Rocket Fiber. Rocket Fiber was founded last June by Marc Hudson, COO Edi Demaj and chief technology officer Randy Foster. All three of these individuals were employees of business man Dan Gilbert’s Quicken loans or Bed Rock Real Estate Services. They introduced to him the idea of high speed internet service that is one thousand times faster than cable or dsl internet. Mr. Gilbert liked the idea so much that he invested in it right away. The business man has invested so much into...

...The Benefits of Twisted Pair Cable Introduction to Networking October 29, 2013 Ocper Inc. is a small company that has no one dedicated to information technology or networking on the staff, and there are 20 Windows peer-to-peer client computers all connected via coax cabling. The president has indicated that the company plans to double in size over the next two years, but she is weary of drastically changing the computing environment. This is my first assignment, but I feel that I have a very good plan to help give them a faster, more secure, and efficient network. The first change that I would recommend would be to move away from a peer-to-peer network to a client/server network. I would explain that there are many advantages to switching to a client/server network such as (Dean, 2009): * User logon accounts and passwords for anyone on a server-based network can be assigned in one place. * Access to multiple shared resources (such as data files or printers) can be centrally granted to a single user or groups of users. * Problems on the network can be monitored, diagnosed, and often fixed from one location. * Servers are optimized to handle heavy processing loads and dedicated to handling requests from clients, enabling faster response time. * Because of their efficient processing and larger disk storage, servers can connect more than a handful of computers on a network. The advantages of a client/server far outweigh any possible disadvantages. ...

...Proceedings of the AABEA Biennial Convention, October 12th, 2002, Washington DC, USA Fiber-optic Telecommunications in the Context of Bangladesh Shabbir A. Bashar*, Member IEEE, Associate Member IEE E-mail: shabbir-bashar@betelco.com Abstract - This paper presents a technical overview of some of the underlying principles of the modern telecommunication technology and the evolution of microwave radio, satellite systems and various optical fiber based infrastructures. Based on the proven superiority of fiber optics combined with the shortfalls of and the complexities faced by the existing satellite systems due to particularly unfavorable regional climatic conditions in and around Bangladesh, the need to link that country to a global submarine optical fiber telecommunication system as the backbone of choice for bulk information transport is underscored. In addition, novel ways of realizing cost effective land based long haul fiber-optic communications networks which use existing electric power lines to suspend optical fiber cables instead of resorting to expensive trenching techniques for cable laying is cited as a viable option given that there are practical examples in both developed and developing countries. Various aspects of optical fiber based wide area and metropolitan area networks such as Optical Gigabit Ethernet are also considered in the context of a mega-city like Dhaka and other highly populated areas. Finally, the economic benefits of having a reliable telecommunication...

...Introduction The company Parstech is undergoing a change in infrastructure. There are several changes which were suggested by the top management. The cost of branch communications should be reduced by using current technology. Besides that, services to be online to make it easier to fix errors. The online services need to be extended up to international level. There should be security for the now-online services. Online services (troubleshooting and maintenance) should be able to continue its operation on 24/7 basis without interruption. Finally, existing technology should be used as much as possible to save cost. Based on the existing technology, it is known that the corporate MAN connection makes use of lease lines. In the office buildings, LAN connection with hybrid bus/star topology is used with Ethernet LAN transmission medium. In the new Network Design, a few additions are present. Figure 1 - Parstech Wide Area Network This network design shows the Wide Area Network and the relationships between the branch offices and the main headquarters. The main headquarters is where the application servers of the company is present. This is to enhance security by placing it in one place. The branch servers are connected to the main headquarters by means of leased lines using the transmission medium fiber optics. The bandwidth and data rate of fiber optics is required to maintain the connection under high network usage. Figure 2 – Sample Internal Architecture of LAN...

...SWOT Analysis Of Verizon Communications Author DeVry University Instructor Principles of Management/MGMT-303ON Spring Session A March 22, 2008 Introduction As Stacy Collet stated, “In order to swat the competition you need to understand SWOT. SWOT stands for Strengths, Weaknesses, Opportunities and Threats. It's a way to analyze a company's or a department's position in the market in relation to its competitors. The goal is to identify all the major factors affecting competitiveness before crafting a business strategy. “Verizon, formerly a Communications has now evolved into an Entertainment Company. Verizon now provides Telephone, Television and Internet services. (ComputerWorld, 2002) History Verizon Communications Inc., based in New York and incorporated in Delaware, was formed on June 30, 2000, with the merger of Bell Atlantic Corp. and GTE Corp. Verizon began trading on the New York Stock Exchange (NYSE) under the VZ symbol on Monday, July 3, 2000. The symbol was selected because it uses the two letters of the Verizon logo that graphically portray speed, while also echoing the genesis of the company name: veritas, the Latin word connoting certainty and reliability, and horizon, signifying forward-looking and visionary. While Verizon is truly a 21st century company, the mergers that formed Verizon were many years in the making, involving companies with roots that can be traced to the beginnings of the telephone...

...Coupling losses between standard single-mode fibers and rectangular waveguides for integrated optics Lars O. Lierstuen and Aasmund Sv. Sudbø The butt-coupling loss between different tapered rectangular waveguides and a standard single-mode optical fiber has been calculated. Losses as low as 0.16 dB can be reached for waveguides with a refractive-index contrast in the range of 0.5% to 1.96%. The fabrication tolerances are such that practical devices with coupling losses below 0.25 dB are feasible. Key words: Coupling loss, optical waveguides, integrated optics. 1. Introduction In optical systems that contain integrated optical components, mode-field mismatch between the fundamental mode of the waveguides of an integrated optical circuit and the optical fiber that is connected to the circuit may cause unacceptable power losses. This problem becomes more important as the refractive-index contrast of the integrated optical waveguides, D, which is given by the core refractive index nco and the cladding refractive index ncl, D5 nco2 2 ncl2 2nco 2 < nco 2 ncl nco , 112 is increased. To achieve a good match to optical fibers, silica waveguides are usually designed to have D in the range 0.3–0.7%. Coupling loss as low as 0.05 dB has been reported for such waveguides.1 Increasing D, however, may be preferable because it makes a reduction of the size 1and hence the price2 of an optical component possible.2 The size reduction is mainly due to shorter coupling lengths...

The idea therefore, is to keep off unwanted persons or objects from ones premises. One’s premise is defined by a boundary which separates private property from the rest of the land. This boundary is referred to as the perimeter. The perimeter could be physical or logical. Physical security is intended to keep intruders from land and grounds around such property. Logical perimeters on the other hand, are for protection against computer sabotage or any other remote malicious activities (Fennelly, 2012). In a nutshell, perimeter security...
