Sporting Goods Company Course Project Proposal Week 3 

https://www.hiqualitytutorials.com/product/netw563-course-project-proposal/

The objective of the project is to recommend a wireless solution for a sporting goods company. This is an individual project. You will be required to submit two assignments for the project. Because of this, you may need to spend additional time and effort in Week 3 to produce the proposal which will form the basis for your project.

Plan on utilizing the Writing Source, available under Student Resources under the Course Home tab on the left, or make use of the official style guide entitled, Writing the Research Paper: A Handbook, 6th edition, by Anthony C. Winkler and Jo Ray McCuen. This handbook includes information on the following styles: APA, MLA, CEE, CMS, and Columbia Online (ISBN – 1413001785).

Scenario: The Wireless Technology Company (WTC), a company that assists organizations and businesses with issues involving network planning and design, has hired you as a consultant. The Athlete’s Shack (TAS) is a chain of sporting goods stores. Because TAS has grown in popularity, it now has 10 stores in the area. TAS is considering implementing a wireless technology that will link all of its stores through wireless broadband service, installing WLANs in each store, and providing its employees with iPads for better customer service. TAS is unsure how to start this process. They have asked WTC for help, and WTC has turned to you.

Create a technical, detailed-oriented report for TAS that explains the process of the project. The format of your technical paper should be based on the following:

Table of Contents

The Table of Contents is a key tool. Use it to format and organize your paper. You can use the headings below as the main sections of your paper.

You Decide Richton Toys Week 5 

https://www.hiqualitytutorials.com/product/netw-563-richton-toys/

Scenario Summary

Richton Toys is an independent toy designer and has been around for about 2 years. Up until now, they have occupied 1/2 of a floor in a 30-story office tower, and are currently using a CAT5 ethernet LAN that a previous tenant installed for their network. Recently, several users have installed a 802.11b network on their own. Moore H. Pschorr, the company CEO, is becoming concerned about the network setup, as corporate espionage is rampant in the toy industry, but so far, the WLAN is popular with his teams. Additionally, the sales department has been complaining about how unprofessional it is to have problems with or lose a connection during a sales meeting or conference. At this point in time, Richton Toys does not have a formal I.T. department, though Jim Coombes, a very tech-savvy user is currently managing it on the side. He also has some ideas for improving the network but may not have all of the skills to make the best decisions. Since the Human Resources department has a clearer view of the company’s future growth in the near future, CEO Moore has asked them to bring in your consulting firm to listen to some ideas from the team, and to provide them with some solid direction where to go….

Recommendation for Municipal Wifi in Bayton City Case Study Week 6 

https://www.hiqualitytutorials.com/product/recommendation-for-municipal-wifi/

Bayton is small Midwestern city of 30, 000 people. The town is located on Lake Michigan and supports a large 600 slip marina that is adjacent to the downtown business district. The downtown has been in decline for the past 15 years. There are a few restaurants, but most of the buildings are boarded up. A number of economic development projects have been tried in the past, but nothing seems to stick. However, there is small historic district surrounding the downtown that has been moderately successful in attracting some “urban pioneers” who have purchased old historic homes and performed renovations.

A telecommunications consultant has proposed a municipal WiFi network for the downtown and marina. The consultant claims that this network will bring in businesses and spark a redevelopment of the downtown.  It could also be used to connect mobile public service personnel such as police, firefighters, and the water department. The signal would blanket the marina, downtown, and offer some penetration into the historic district. The consultant is seeking a $50,000 commitment from the city to cover the initial cost of equipment and deployment and would negotiate a yearly maintenance contract. The consultant claims that new businesses, increased traffic at the marina, and the savings on the public service network would offset the cost of the network.

Currently, Internet access is available downtown through Comcast and AT&T DSL There is an adequate 3G wireless footprint throughout the city. The marina is not served by Comcast or a telco DSL service.

You are a local IT professional and the mayor has asked you to evaluate this proposal and make a recommendation to the city council. Use the information obtained in Case Study 1 to support your decision.

Subjects Covered: Information technology, Internet, Service management, Technology & operations, Telecommunications, Telecommunications industry.

In Case Study 2, focus on the following issues:

– The potential of the Municipal WiFi network to spark investment based on your previous research

– The potential to leverage the network for municipal services such as police, fire, meter reading, etc…based on your previous research

– The potential for the city to provide a internet access as a public utility, akin to the water department or garbage collection based on your previous research

Preview:

A number of municipal wifi implementations have been successful.  For example, Arcata, a town in California, has implemented free municipal wifi.  It can be accessed by…
