Multiple Schools. Performing The Calculations¶
Creating A Project¶
The following process outlines how to create new project in a Broadband Calculation Tool: Schools. This program has eight different tabs, that are organized as a series of questions that provide for main user inputs. This section gives you step-by-step instructions for adding or revising data under each of the tabs.
Exploring the tabs of a Broadband Calculation Tool: Schools. Under each tab, the application presents one or more worksheets. Position the mouse pointer inside a worksheet cell, and click the mouse button to select this cell. If the cell is editable, you can then enter or change its value, for providing correct calculations for your project.
Step 1. Navigate to the Account tab on the main menu and select "Create New Project" in the center of Home page (Figure 1).

After you input initial information about your project in previous tab Project Name And Description in Project Name and Description part you'll go to "Broadband connection calculation" tab.
Figure 1. Broadband connection tab¶
This tab offers you different options for broadband connection calculation. You can select one of 3 possible options:
By selecting "Calculation only broadband connection of schools to the nearest network points of presence (PoP)" in the project it will be considered next positions: evaluation of broadband connection deployment and operation costs, estimation rates of return and selection of select suitable connection technologies (Figure 2). After selection of this option you'll go to tab Calculation Of Required Bandwidth
Figure 2. First option¶
By selecting "Calculation only broadband connection of schools to the nearest PoP with broadband connections between schools" it will be considered next positions: evaluation of broadband connection deployment and operation costs, estimation rates of return and selection of select suitable connection technologies and with calculation of an optimal (from the economic point of view) network structure where all schools are represented as interconnected network nodes. Also in this option you should select one of the following criteria that will meet your needs:
Cost of ownership - select this option if you would like us to use cost of ownership as a criterion to choose the best broadband connection options
Net present value - select this option if you would like us to use net present value as a criterion to choose the best broadband connection options (Figure 3). After selection of this option you'll go to tab Calculation Of Required Bandwidth .

If you want to define specific bandwidth value to connect your schools to the broadband network yourself select first option "I know required bandwidth" button (Figure 2). After this you skip Selecting Traffic Profile tab and you'll go straight to Selecting Broadband Connection Technologies tab.
Figure 2. "I know required bandwidth" button¶
If you need help in bandwidth calculation, select one of two other options. Here you can:
Calculate the required bandwidth and select technologies to connect your school to the broadband network (Figure 3)
Calculate the required bandwidth, but without technology related parameters calculation (Figure 4).
Figure 3. "Calculate the bandwidth" option¶
Figure 4. "Calculate only the required bandwidth" option¶
After that you'll go straight to Selecting Traffic Profile tab.
If you want to change parameters on previous tab, select "Go back" button. After that you'll go back to "Broadband connection" tab (Figure 5).
Figure 5. "Go back" button¶
Selecting Traffic Profile¶
Traffic profile gives you an option to choose necessary services consumption intensity and quality of services parameters that will be used in your network.
Figure 1. "Traffic Profile” tab¶
You can combine this two parameters to select the most sutable option among nine offered predefined variants in table (Figure 2).
Figure 2. Traffic parameters selection¶
You can also easily create your own traffic profile. Select the "User Defined Traffic Profiles" option and click on "Add new profile" button.
Figure 3. User Defined Traffic Profile¶
When you click on "Add new profile" button, you'll be redirected to traffic profile generator.
Figure 4. Traffic Profile Generator¶
There are only two types of fulfilling "Profile Service Consumption Intensities" field: "Customer service" option or "Predefined Services" option. It is important to indicate which option you need. "Predefined Services" option gives more diverse choice of services you use, when "Customer service" only include intensities of customer service device (Figure 5).
Figure 5. Service consumption intensities options¶
"Predefined Services" option. Select usage intensity of each service for the traffic source in "Service consumption intensity" field in following table "Predefined Services" option. Select "Not used" option if a service is not used. Set "Not used" option for all services if there is no such traffic source (Figure 6).
Figure 6. "Predefined Services" option¶
In "Profile quality level" table select one of three possible options (Figure 7). Here you can choose:
Low. For Schools in hard-to-reach areas (including rural) in the countries where the internal backbone is not developed now and/or the external connectivity to the international communication channels is poor.
Medium. For Schools in developing countries with existing broadband coverage for at least 50% of population & territory with more than one external international communication channel.
High. For Schools in developed countries with good broadband coverage and international communication channels.
Figure 7. "Profile quality level" option¶
In "profile name" field you write the name of your own "Traffic Profile" parameters. Which will be saved in system under the name you've selected (Figure 8).
Figure 8. "Profile name" field¶
In "Custom services" table you can add new services that are not included in "Profile Service Consumption Intensities" field including their individual parameters. Also you can do it in "Simple" or "Extended" mode. In "Simple mode" you input average parameters for your service, while in "Extended mode" you can input parameters for different quality levels for each service (Figure 9).
