In order for the company to establish a long-distance, high-throughput wireless connection, 802.16 (WiMAX) technology should be used. This technology which stands for Worldwide Interoperability for Microwave Access, is able to transmit and receive signals up to 30 miles when the antennas are fixed. Its maximum downlink throughput is 120 Mbps and its maximum uplink throughput is 60 Mbps.
Some of the benefits of WiMAX compared to T3 over SONET connection are that a single WiMAX station can serve hundreds of users, it has a much faster deployment of new users comparing to wired networks, and it can reach a speed of 10 Mbps at 10 kilometers with line-of-site customers. It also supports Non line of Sight customers; it is standardized, and same frequency equipment should work together and it has short delay. Drawbacks of WiMAX are that weather conditions like rain could interrupt the signal; other wireless equipment could cause interference, multiplied frequencies are used, WiMAX is a very power intensive technology and requires strong electrical support, and it has high installation and operational costs.
The equipment needed to install WiMAX includes the Wimax base station, which consists of indoor Wimax equipments and a wimax tower. The common range of Wimax base station is up to 10km radius, while a base station can cover 50km or 30miles but in practice it is 10km and 6 miles only .Any node inside the coverage area would be capable to access the internet. Wimax base station work as a media access control layer and allocate uploading and downloading bandwidth according to the subscriber requirements. The Wimax receiver is a stand-alone box or PCMCIA cards which is located in your computer or laptop. It is also called customer promise equipments. Also neede is a Wimax antenna is also a standalone box and sits in the laptop or computer .Wimax antenna is just like a

Synopsis and Objectives

...Synopsis and Objectives This case presents the cash flows of eight unidentified investments, all of equal initial investment size. The task is to rank the projects. The first objective of the case is to examine critically the principal capital-budgeting criteria. A second objective is to consider the problem that arises when net present value (NPV) and internal rate of return (IRR) disagree as to the ranking of two mutually exclusive projects. Finally, the case is a vehicle for introducing the problem created by attempting to rank projects of unequal life and the solution to that difficulty—the equivalent-annuity criterion.

From studying the interviews of key stakeholders and their expert opinions, a collection of functions can be identified so that the HRIS deliverable’s function/purpose is defined. This initial planning will help to develop the Project Charter and set the stage for all the work that need to be performed. GenRays has subject matter experts on staff whose input it vital to produce an HRIS that meets the particular needs of the GenRays staff. We need to make sure that all of the work required to produce a HRIS product for GenRays is done. We also want to ensure extraneous work is avoided to keep GenRays costs low. We will use the interviews here to determine how the project’s scope will be defined, validated, and controlled. GenRays had reached the ROI point very early with the last on the project and defining scope well here will allow for a similar success. Decomposition of the work that needs to be done is a tool that will help aid in identifying the exact work that needs to be done and help to create the WBS. To further, ensure that the project runs smoothly and stays on track. We will use tools to track and manage the project’s completion. We can use the process of Decomposition that we have used to break down the projects’ scope into manageable...

Case Write-Up the Investment Detective

...Case Write-Up: The Investment Detective Case Summary The purpose of this case is to become a capital budgeting analyst and evaluate which set of free cash flows for 8 projects will result in the most effective investment for a firm’s capital. The objective given is to rank the four best that the company should accept. The case is broken down into three separate steps including the given information about estimated cash flows (inflows & outflows), determining the appropriate discount rate, and evaluating the cash flows using the IRR (Internal Rate of Return), MIRR (Modified Internal Rate of Return), NPV (Net Present Value), and other metrics. Each project is chosen solely on the basis of the quantitative analysis. Here are some factors to consider for this case: Each project has the same initial investment of $2 million; in addition, all are believed to be of the same risk class. The managers have determined that projects 7 and 8 are mutually exclusive. The issue is that the WACC has never been officially estimated and in the past the discount rate has been assumed at 10 percent (however, certain officers have asserted the discount rate to be higher). Ranking Projects Ranking projects simply through the inspection of cash flows is inadequate due to the time value of money and cost of capital of companies; the only piece of information that can be derived from looking at the cash flows is the amount of time it would take to be paid back (regular payback period).

The case is all about to choose one of two projects while the models that have been used gave a different recommendations with considering “a large developer of business software and application programs, had been experiencing a downturn in operating revenues over the past three quarters” Questions: 1. Phyllis has called you into her office to help her make sense of the contradictions in project evaluation. How would you explain the reasons for this divergence of opinion from one technique to the next? What are the strengths and weaknesses of each screening method? The main reason of the divergence in Score model and NPV refers to the type of each model where the score model is a non-financial and the NPV is a financial screening method. Therefore and firstly I would say that using only these two methods is insufficient and second, I would suggest to Ms. Phyllis to use another type of screening methods such as The Analytical Hierarchy Process or the IRR to give us more accurate alternative methods. Although that scoring model is easier to use in tying critical strategic goals for the company and easy to understand and comprehend; it has few disadvantages of as the following: 1- The scaling from 1 to 3 is a guesswork which is basically not very accurate. 2- We do not know by how much is the category is better than the other, as number...

The Investment Detective

...Detective 1. Can you rank the projects simply by inspecting the cash flows? The company is able to perform initial ranking based on the cash flows overview, although it will not be sufficient to determine the true profitability. In this case the ranking of the projects is the following – 3, 5, 8, 4, 1, 7, 6 and 2. This ranking is supported by the excess of cash flows (CF). 2. What criteria might you use to rank the projects? Which quantitative ranking methods are better? Why? Based on the theory of the capital budgeting evaluation techniques, the investments consideration will be analyzed upon Net Present Value (NPV), Payback period and Internal Rate of Return (IRR). The concepts will support ranking from the greatest project to less attractive one. First criteria that is used for ranking is the NPV method. It is considered as the most useful method because it is based on Cash Flows of the projects throughout their entire period. Of course it incorporates the time value of money concept and represents net value of the projects or net benefit that accrues to the company. Ranking assessment will consider as acceptable investment only projects with positive NPV. The second criterion is the IRR evaluation method. It is also an alternative to NPV method. Basically IRR is a discount rate that equates the present value of project’s expected cash flows to the initial invested amount. The successful ranking criteria for the acceptable projects, is to have IRR greater than the...
