Chapter 2 Introduction to WLAN Planning and Planner Wireless Local Area Networks (WLANs) connect you instantly even while you are moving. They provide convenient and increasingly flexible productivity in today’s corporate and industrial environment. However, WLANs need to be properly planned for adequate coverage and security to get these benefits. This chapter discusses the disadvantages of poorly planned WLANs and presents Planner as the solution to such problems. Planner plans the entire network with the help of various outdoor objects namely, buildings, trees, water bodies, indoor building objects namely, walls, windows, doors, elevator shafts, furniture, concrete columns, and metal objects; and devices such as Access Points (APs) and Sensors. The initial input to Planner is a layout image in any graphical format. As an output, it generates various RF views and then assembles these views into a comprehensive RF planning report. 2.1 What is Wi‐Fi? Wi‐Fi is another name for IEEE 802.11 based WLANs. These networks operate at and use 802.11a, 5 GHz, 802.11b/g, 2.4 GHz and the emerging 802.11n, 2.4 and 5 GHz. Wi‐Fi is promulgated by the Wi‐Fi Alliance. Products certified as Wi‐Fi compatible by Wi‐Fi Alliance are interoperable with each other even if they are from different manufacturers. You can use any brand of AP with any other brand of Client hardware that is built to the Wi‐Fi standard. Wi‐Fi has gaining acceptance in homes, offices, and public places like coffee shops, hotels, and airports. 2.2 Disadvantages of Poorly Planned WLANs Poorly planned WLANs have the following risks: • Low Performance: Lack of coverage, capacity, and throughput planning results in poor connectivity speeds in certain areas. This could result in low performance of the network. • High Security Risk: RF signals spill due to the very nature of the wireless network environment. For example, hackers could tap into the WLAN from the parking lot or the street. This can lead to serious security breaches. • Bad User Experience: Low performance, throughput, or coverage lead to bad user experience. • High Operational Expenses (OPEX): Network administrators have to spend a lot of time and effort in troubleshooting issues, quality of service, and security exposure after the deployment of networks. This leads to higher operational expenses. • Lower Return on Investment (RoI): A poorly planned network results in a lower RoI as the productivity gains are not as high as predicted. The current state‐of‐the‐art is to carry out a site survey (also called radio survey), use best practices for AP placement, or even perform deployment on ad hoc basis. These methods have the following limitations: • Site surveys are time consuming, expensive, and prone to errors. • Ad hoc deployments pose difficulty in visualizing network coverage, lead to security exposure, and cause channel interference. • ‘What‐If’ scenarios are not possible in site survey or ad hoc deployment methods. There is no established practice for planning WLAN security networks, an essential part of IT security in today’s network environment. Pre‐deployment enables successful WLAN deployments by: • Maximizing network coverage and throughput • Minimizing channel interference • Minimizing security exposure by ensuring minimum signal spillage outside the designated area of WLAN operation • Providing ‘What‐If’ scenarios for trade‐off between security exposure due to signal spillage and network coverage • Maximizing the detection and prevention range of WLAN security Sensors • Planning Sensors to ensure reliable location tracking of unauthorized devices • Ensuring that even the weakest transmitter is detected and prevented by the Sensors • Planning to enable live 24x7 RF monitoring • Troubleshooting remotely • Restructuring the whole plan especially while extending the existing office space or deploying new equipments 2 3Com ® AirProtect Planner User Guide Introduction to WLAN Planning and Planner 2.3 Planner: A Complete WLAN Planning Solution Planner makes the task of WLAN planning simple. Its easy‐to‐use interface provides rich visibility into security exposure, RF coverage, channel allocation, and available link speed in WLANs. This ensures security, high reliability, and optimal configuration of WLANs.

If you enter invalid data or select an invalid file, Planner displays an alert. The Planner outputs are: • Project file created and saved as an XML file with an extension ‘.prj’. • Planner file created and saved as an XML file with an extension ‘.spm’. If at a later point, you modify and save this XML output file, by editing it in a text pad, the file becomes corrupt. After that, you will not be able to open this file in Planner. A .spm file is bound to a .prj file. You cannot create a .spm file only. When you try to open a .spm file separately and not through the Project, Planner creates a default project, creates a node for that .spm file under the ‘Root’ location folder, and displays the .spm file. The project layout appears as follows. 7 3Com ® AirProtect Planner User Guide Launching Planner Figure 5. Project Layout The new Planner project layout screen is divided into three panes as follows: 1 Menu and Toolbars at the top: The Menu bar provides Planner operations. The Toolbar provides buttons for quick operations. The operations enable you to design and view the layout. Refer to the section Menu Items for more details. 2 Left pane consists of the Locations tree at the top and the Devices list below: The Locations tree contains location folders and location nodes. On launching a new project, Planner creates the Locations tree with the as the root location. The Devices list contains a list of devices placed on the floor map. You can see this device list only if the Location Node is loaded. The Locations tree and the Devices list are discussed further in the section Working with Location Tree and Devices List. 3 Right pane consists of the Planner Layout Model for the location. The Planner Layout Model is the viewable layout area for the location selected in the Locations tree. 3.3 Support for AutoCAD Planner supports AutoCAD files. An AutoCAD file contains the dimensions of the layout and also a list of layers in the layout. When imported into Planner, Planner automatically populates the Dimensions field. You can edit the dimensions. Once these dimensions are accepted, the Manage Layers screen appears where you can select the required layers. Planner selects the layers that are turned on in the AutoCAD file, by default, and based on that, imports and models all the objects from these layers. You do not have to re‐model these objects. Refer to the section Managing Layers to know more about managing layers of an AutoCAD file. Planner supports the following versions of AutoCAD files: • Autodesk DXF Release 10, 11, 12, 13, 14, 2000, 2002, 2004/2005/2006 • Autodesk DWG Release 9, 10, 11, 12, 13, 14, 2000, 2002, 2004/2005/2006 8 3Com ® AirProtect Planner User Guide Launching Planner Planner allows importing of the following information from an AutoCAD file. • Layout Dimensions • Layer Information Planner supports the following shapes of objects. All these shapes must be 2D. • Lines • Rectangles • Polygons • Circles • Arcs However, Planner does not support the following shapes: • Doughnut • Hollow Arcs • Curved Polygons • Spline • 3D objects 9 3Com ® AirProtect Planner User Guide Working with the Locations Tree and the Devices List Chapter 4 Working with the Locations Tree and the Devices List Planner enables you to model the enterprise across locations. It also enables you to place devices on a location to ensure optimum coverage. The Locations tree and the Devices list features appear on the left pane of the project layout screen. 4.1 Locations Tree The Locations tree enables you to organize the network into a list of locations and view live 802.11 RF coverage maps for each location node. The tree also helps you easily navigate through the locations and switch between different floors. The Locations tree comprises of location folders and location nodes. Location folders represent organizational components such as buildings, cities, or countries. • ¾ Root Location: This is the root location. Planner assigns the Project Name you select, as the name for the Root Location. You can rename this location. However, you cannot delete or move this location. • Location nodes represent component details such as a floor in a building. For example, Hawaii Conference Room, Bldg 15–Cubicle G2, or Executive Area. You can perform various functions like adding, deleting, renaming, moving a location, and so on from the Locations tree. 4.1.1 Adding a new Location Folder In the Locations tree, right‐click the location folder under which you wish to add a new location, and select Add Location Folder. The New Location Folder dialog box appears. Figure 6. • • • 4.1.2 Adding a New Location Folder Name: Enter the desired name for the new location folder. Location Map: Specify the location of the Location Map. Alternately, click to navigate to the graphical location map that you wish to import into the location folder. Consider Cross Floor Spillage: Select this checkbox to enable cross floor spillage. Planner pops up an alert to warn you that this action is irreversible once Cross Floor folder is created. You cannot de‐select or change this option at a later point. Adding a new Location Node In the Locations tree, right‐click the location folder under which you wish to add a new location node, and select Add Location Node. The New Location Node dialog box appears. 10 3Com ® AirProtect Planner User Guide Working with the Locations Tree and the Devices List Figure 7.

Specify the following details of the Location Node: • Name: Enter the desired name for the new location node. • Plan Type: Specify if the plan type is an Indoor or Outdoor layout. • Location Map: Specify if the Location Map is a .jpg or .gif Image, or an AutoCAD file. Click to navigate to the graphical location map that you wish to import into the location node. Once you select and import an AutoCAD file for a location node, the Manage Layers dialog box appears. 11 3Com ® AirProtect Planner User Guide Working with the Locations Tree and the Devices List Figure 8. • • Managing Layers of an AutoCAD file Ceiling Height: Enter the desired ceiling height for the layout. Ceiling Material: Select the desired ceiling material for the layout from the drop‐down list. Note: Location Map – AutoCAD option, Ceiling Height, and Ceiling Material are available only if you select Indoor Layout as the Plan Type. They are not available for an Outdoor Layout. • • • • Regulatory Domain: Different countries have regulatory agencies permitting a select number of channels for protocols. Select the relevant country from the drop‐down list for which you are doing WLAN planning. Application Environment: Select the desired application environment from the drop‐down list. Min Attenuation Factor: Specifies the minimum attenuation factors for 802.11a/n and 802.11b/g/n protocols, depending on the application environment selected. Max Attenuation Factor: Specifies the maximum attenuation factors for 802.11a/n and 802.11b/g/n protocols, depending on the application environment selected. Dimensions • Unit: Select the unit of measurement you want to use for the layout from the drop‐down list. • a: Specify the length of the layout. • b: Specify the width of the layout. • Lock Aspect Ratio: Allows you to maintain the ratio of the length and width of the layout to that of the Layout image selected earlier. To achieve this: 1. Select Lock Aspect Ratio before entering the dimensions of the layout. 2. Enter any one of the two dimensions of the layout. The value of the other dimension is automatically entered as per the default aspect ratio. • Layout Dimensions: Displays a preview of the layout map. Incase you do not know the dimensions of the layout, click . The Find Layout Dimensions screen appears. 12 3Com ® AirProtect Planner User Guide Working with the Locations Tree and the Devices List Figure 9. Finding Layout Dimensions Click one point, then drag the mouse and click another point. The Dimension dialog box appears. Figure 10. • Dimensions Distance: Specify the distance between the two selected points on this map. The unit of measurement is the one mentioned in the New Location Node dialog box. Planner uses this information to scale the dimensions of the layout, and displays the same in the corresponding fields in the New Location Node dialog box. Note: Ensure that the distance you specify in the Dimension dialog box is accurate. Otherwise, there will be drastic difference in the actual dimensions and the dimensions calculated by Planner. If you import an AutoCAD file, Planner extracts the dimensions from the AutoCAD file. It is sometimes observed that the dimensions derived from the AutoCAD file are not correct as it shows the complete canvas size. Hence, ensure that you enter the exact dimensions of the layout. Copying of Objects: • Copy Objects From: Allows you to copy all objects from the previously created layouts. Select the layout from which you want to copy objects from the drop‐down list. • Copy Options: Select the items you wish to copy: Layout Objects, Devices, and Calibration Points. Note: Planner enables Copying of Objects only if there is more than one node under a location folder and that folder has Consider Cross Floor Spillage activated. 13 3Com ® AirProtect Planner User Guide Working with the Locations Tree and the Devices List Once you are done and click , a Confirm dialog box to open the created location appears. Alternately, click to discard action. Cross Floor Location folder When you create a location folder with the Consider Cross Floor Spillage checkbox enabled, then information of all the nodes is bundled and stored in one single .spm file. By default, the name of the .spm file is the name of the first node that you create. It is possible to add a location node under a Cross Floor location folder. However, you cannot add a location folder under a Cross Floor location folder. The dimensions of all the nodes in a Cross Floor folder are the same. For example, while defining Node‐1, you specify a = 500 and b = 600. Then, Planner uses the same dimensions for all the nodes created thereafter in that folder. Since Planner extracts the dimensions automatically in case of an AutoCAD file, these extracted dimensions must match the dimensions of the first node that was created. Otherwise, Planner does not allow the import of the AutoCAD file. Additionally, when you create the second node under the Cross Floor location folder, you cannot change the regulatory domain. Note: To modify the dimensions of a node under a Cross Floor Location folder, right‐click a node and select Load Location Node. Planner automatically applies these dimensions to rest of the nodes under this folder. The Cross Floor location folder is represented by the icon. Non‐Cross Floor Location folder When you create a location folder without the Consider Cross Floor Spillage checkbox enabled, information of each node is stored in separate .spm files. You can add a Cross Floor location folder under a Non‐Cross Floor location folder. The Non‐Cross Floor location folder is represented by the 4.1.3 icon. Managing Layers The Manage Layers dialog box displays details of layers in an AutoCAD file. When you select and import an AutoCAD file for a location node, the Manage Layers dialog box appears. Figure 11. Managing Layers of an AutoCAD file 14 3Com ® AirProtect Planner User Guide Working with the Locations Tree and the Devices List In the Manage Layers dialog box, some or all the layers are selected by default. This is because every AutoCAD file stores the status of the layers that are turned on or off based on the selected checkboxes of layers. • Layer Name: Select the checkbox against the layers you want. You can override the existing status of each layer by manually selecting them based on your requirement. • Material Type: Select the material type from the drop‐down list, as populated from the material repository. Planner uses all this information to model the objects on the floor map. • Preview: Reflects the changes with the selection of layers. • Enlarge this view: Click to view the enlarged view. • Restore to normal View: Click to restore the enlarged view to normal view. Click to execute the changes made. On the Manage Layers screen, if you click , the AutoCAD file is not imported and you will see a blank image on the layout model. CHECKSUM: When you load a node with an AutoCAD file, Planner validates the attached AutoCAD file. Planner checks the CHECKSUM value of that AutoCAD file and verifies it with the CHECKSUM value stored in the .spm file for that AutoCAD file. This is the value stored when the AutoCAD file was first imported. If there is any mismatch in this value, Planner still loads the node but does not allow you to use the Manage Layers option. Planner pops up an alert to inform you about this. 4.1.4 Viewing/Loading a Location Loading the location node means opening the .spm file associated with the node. You can open only one node at a time. You cannot view a location layout unless you load it. To view/load a location, right‐click a location node from the Locations tree and select Load Location Node. Planner launches the layout on the layout model pane. The title bar of the screen reflects the path of the selected location. Note: A .spm file created with the previous versions of Planner does not have any application environment assigned to that file. When you import that file and try to load the node, then Planner pops up an alert asking if you want to assign the default application environment. 15 3Com ® AirProtect Planner User Guide Working with the Locations Tree and the Devices List Figure 12. Loading a Location Node When you load a location attached to an AutoCAD file, the background has a blank image and you can draw all the objects on that, unlike in case of an image where the layout has the .jpg or .gif as the background image. When you click a location node attached to an image, Planner displays the image on the layout model pane. 4.1.5 Closing a Location Node You can close a location node in Planner. Planner unloads the location node leaving only the layout on the layout model pane. To close a location node that you have loaded, right‐click a location node from the Locations tree and select Close Node. Additionally, if you click any other node from the locations tree, Planner closes the current node. 4.1.6 Importing a Location Planner enables import of Planner Project files (.prj), Planner files (.spm), and compressed Planner Project files (.zip) into a location. Use either of the following steps to import a file: • Go to FileÆOpen. • Right‐click a location folder from the Locations tree and select Import. The Open dialog box appears. 16 3Com ® AirProtect Planner User Guide Working with the Locations Tree and the Devices List Figure 13. Importing a Location Specify the path of the file or navigate to the file you wish to import into the location folder. Select the file type from the Files of type drop‐down list. • On importing a .prj file, the entire location hierarchy of that project is imported under the selected folder. On importing a .spm file, Planner creates a node under which the .spm file is imported. • • On importing a .zip file, Planner unzips the file at a temporary location and then imports the .prj file. The Import Project dialog box appears where Planner asks you if you would also like to import the project preferences options. Figure 14. 4.1.7 Import Options Cut/Copy/Paste a Location You can cut/copy location folders and nodes, and paste them onto other locations. 1 Right‐click a location folder or node that you want to cut/copy, from the Locations tree. Select Cut or Copy. 17 3Com ® AirProtect Planner User Guide Working with the Locations Tree and the Devices List Figure 15. 2 Copying a location Right‐click the destination location folder onto which you want to paste the location selected in the above step. Select Paste. If the location where you are pasting the location folder or node already has a folder or node with the same name, Planner renames the copied objects incrementally with a suffix ‘01’, ‘02’, and so on. Note: If a node belongs to a Cross Floor location folder, you cannot Cut/Copy and Paste that node into another folder. If you want to copy that node, you must copy the entire Cross Floor location folder. 4.1.8 Moving a Location You can move location folders and nodes within a location folder. This changes the location hierarchy of that folder in the project. Note: You cannot move a location if the location is not under the same parent location folder. Use the following steps to move a location: 1 Right‐click a location folder or node from the Locations tree. 2 Select Move Up or Move Down. 3 Repeat the above steps until you reach the destination folder under which you want to move the selected location. Figure 16. 4.1.9 Moving a location Placing Locations on a Location Folder with an attached image Planner enables you to place locations on a location folder that has an attached image. This helps you identify the physical position of each of the locations. The locations placed on the attached image are indicated by green colored circles.

The system will behave similarly with Layout Name and User defined names. 55 3Com ® AirProtect Planner User Guide WLAN Planning Wizard Chapter 6 WLAN Planning Wizard WLAN Planning Wizard is a feature in Planner that helps you plan the layout as per your requirements. The wizard helps you define objectives by seeking your inputs on Wi‐Fi network parameters. Planner uses these given parameters to make available number of APs required on a floor, assigning channels to them, and placing the same on the floor map. Go to ToolsÆWLAN Planning, or click on the Toolbar to open the wizard. Planner verifies and validates details like devices on the floor map and defined area polygons before launching the wizard. If the layout has manually placed devices, then Planner asks if you wish to delete the devices from the layout. If you select , Planner does not delete the devices. However, the WLAN Planning Wizard does not consider these devices for any calculation. It also prompts you to define area polygons before continuing with the wizard. This is not a mandatory step. Planner also displays an information pop‐up about the significance of defining area polygons. The pop‐up asks if you wish to draw the area polygon. Figure 67. Defining Area Polygon: I-Pop-up Defining the area polygon helps confirm that you place all the devices within the area polygon and not outside it. Click to draw the area polygon. Alternately, click to discard the action. Recommended: Define area polygons if you have an irregularly shaped layout, as AP placements in such layouts might not be as expected. Then, the welcome screen appears. 6.1 1 Steps in WLAN Planning The Welcome to WLAN Planning Workflow screen shows the steps in the WLAN Planning workflow. 56 3Com ® AirProtect Planner User Guide WLAN Planning Wizard Figure 68.

If the desired AP model does not exist in the device repository, click to exit the wizard and add the custom AP to the device repository by following steps in the Add AP section. Recommended: Choose a device with omni directional antenna, in order to get results that are more accurate for capacity calculations. Capacity calculation results may be incorrect when you use directional antennae. If the power values for the radios are invalid in the region for which you are planning, the planning wizard prompts you to select another radio or device. • The AP Properties table displays pre‐defined AP details like Radio(s), Active Protocol, Transmit Power (mW) and Antenna Gain (dBi). Enter the following details: ¾ Radio: Select the desired active protocol(s) of the AP you want to use on the current floor. ¾ 802.11n Properties: Click . The IEEE 802.11n Advance Parameters dialog box appears. You could either view or change the advanced 802.11n parameters for that radio.

Frame Aggregation: Select either AMSDU or AMPDU, or both checkboxes for the desired frame aggregation. For more details on the advance parameters, refer to Appendix D: Glossary of Terms. • 3 Channel Allocation Strategy: Due to limited available frequency spectrum for 802.11 WLANs, dense AP deployment often requires spatial reuse of frequencies. The strategy you chose determines the set of available channels. Planner assigns channels to minimize interference. During on‐site planning, interference from the existing APs is considered. Select either of the options for channel allocation strategy. ¾ Only non overlapping channels: These are channels that do not interfere with each other. For example, in the US, 2.4 GHz band offers three non‐overlapping channels – 1, 6, and 11. ¾ All available channels: All channels are considered. For example, in the US 2.4 GHz band offers 11 channels. Using partially overlapping channels (say 1, 4, 7, 11) can improve overall WLAN capacity. The WLAN Planning Wizard: Planning Objective screen helps you specify the planning objective for the 802.11 WLAN, while also guiding you in planning. Figure 72. WLAN Planning – Planning Objective Planner allows you to choose the focus of WLAN planning. Based on the focus, Planner considers different factors for populating the number of APs required and their placement. Select one of the following options: • Coverage Planning: Select to plan the WLAN to enable users at most locations on the floor to connect with a specified minimum data rate. • Capacity Planning: Select to plan the WLAN to ensure connectivity with focus on user and application requirements. 4 5 6 Depending on the planning focus that you chose in the previous step, Planner displays the Coverage Planning or Capacity Planning screen of the wizard. Once you are done with the WLAN planning, the WLAN Planning Wizard: Summary screen appears depending on the type of focus. If you wish to change the settings, click . Click to exit the wizard. Planner will auto‐place the APs on the floor map, and assign channels to them. Coverage Planning If you have selected Coverage Planning in the previous step of the wizard, the WLAN Planning Wizard: Coverage Planning screen appears. The maximum data rate supported by an AP depends on the quality of the signal received from that AP. Due to RF path loss, the signal quality degrades as you move away from an AP, in turn leading to connectivity at lower data rates. In a coverage‐focused plan, you define a minimum data rate for the floor. You plan a WLAN such that users at most locations 59 3Com ® AirProtect Planner User Guide WLAN Planning Wizard on the floor can connect with atleast the specified data rate. Figure 73. • • WLAN Planning – Coverage Planning AP Model: Displays the AP Model. The AP Properties table displays the Active Protocol.

The list contains available and applicable data rates for the active protocol set for each radio in the Device Selection step. Note: If you have selected the same active protocol for more than one radio in the Device Selection screen, Planner displays only one common row in the table in the above screen. Planner derives the data rate for 802.11n devices from the channel width and guard interval values. The WLAN Planning Wizard: Coverage Planning Summary screen appears. Figure 74. Coverage Planning Summary The Coverage Planning Summary screen gives you a summary of the coverage‐focused plan as per your requirements and 60 3Com ® AirProtect Planner User Guide WLAN Planning Wizard specifications. It also gives you the number of APs, as estimated by Planner to suit your requirements of coverage. Capacity Planning If you have selected Capacity Planning in the previous step of the wizard, the WLAN Planning Wizard: Capacity Planning – Parameters screen appears. Capacity of an AP refers to the maximum achievable throughput of that AP. Several factors such as number of active users, type of applications, RF interference and so on affect the capacity of an AP. To provide enough bandwidth per user, you must plan a WLAN by considering these factors in addition to coverage. Figure 75. WLAN Planning – Capacity Planning Specify the parameters for Capacity Planning: • Number of active users on the layout: The expected number of users simultaneously accessing the WLAN on the current floor. • Typical expected throughput per user: Specify the bandwidth typically required per user. The total expected WLAN capacity is a product of the number of active users and bandwidth required per user. Click to view the typical per user throughput for various application types. • Percentage uplink traffic: Specify the percentage flow of uplink traffic. Uplink traffic refers to the flow of traffic to an AP in a WLAN. The amount of uplink traffic indicates the conflict among users for medium access. Note: A high percentage of uplink traffic with a large number of active users will degrade an AP’s bandwidth due to high contention. • Provision for VoIP: Select to enable Planner to provide for VoIP. VoIP has a major impact on capacity planning and is determined by: ¾ Voice codec type: Select the voice codec type from the drop‐down list. ¾ Voice traffic: Specify the percentage voice traffic. ¾ Number of voice calls per AP: Specify the maximum number of VoIP calls that an AP can simultaneously support. The WLAN Planning Wizard: Capacity Planning – Advance Parameters screen appears. 61 3Com ® AirProtect Planner User Guide WLAN Planning Wizard Figure 76. Capacity Planning – Advance Parameters Specify the factors you would like to consider for WLAN capacity planning. These are ‘What‐If’ scenarios. • Select the effects on AP capacity: ¾ 802.11 medium access anomaly: Select to consider the proportion of active users at various data rates. ¾ 802.11 medium access contention: Select to consider bandwidth contention determined by the total number of active users per AP and the amount of uplink traffic. ¾ 802.11 bandwidth efficiency: Select to consider the impact of overhead on bandwidth efficiency. • Select either of the type of per AP capacity estimate (based on the selected factors) to plan the WLAN: ¾ Conservative: Uses the worst case per AP capacity to estimate the number of APs required. This option usually estimates more number of APs. ¾ Optimistic: Might overestimate per AP capacity than observed in practice. This usually requires less number of APs compared to the Conservative estimate. ¾ Average: Moderately estimates per AP capacity and is a balance between the Conservative and Optimistic options. This is the default selected. • Accounting for the effect of Wi‐Fi interference gives a more accurate estimate of capacity. For instance, in a scenario with densely packed APs, the inter‐AP interference may considerably degrade the capacity. In some cases, the capacity requirement may not be feasible due to high interference. Specify if you want to consider the effect of Wi‐Fi Interference. ¾ Yes ¾ No The WLAN Planning Wizard: Capacity Planning Summary screen appears. 62 3Com ® AirProtect Planner User Guide WLAN Planning Wizard Figure 77. Capacity Planning Summary The Capacity Planning Summary screen gives you a summary of the capacity‐focused plan as per your requirements and specifications, results of the ‘What‐If Scenario Analysis’, and the number of APs, as estimated by Planner to suit the user and application requirements of capacity. Planner also gives you its analysis of feasibility of capacity planning as ‘Passed!’ or ‘Failed!’, with the given settings. It estimates if the planned capacity is achievable with the current configuration; and if it is not, then it gives the potential reason for failure. • If the Capacity Feasibility Check is ‘Passed!’ (Green), it implies that the planned capacity is achieved. Figure 78. • Capacity Planning Summary – Passed! (Green) If the Capacity Feasibility Check is ‘Passed?’ (Orange), it implies that the planned capacity is achieved. However, there are some extra APs, which Planner cannot place using Auto AP placement on the layout. This screen also displays a ‘?’ link for Estimated max capacity (with Wi‐Fi interference) in the ‘What‐If Scenario Analysis’ section. This implies that Planner is unable to calculate the estimated maximum capacity with Wi‐Fi interference as all the estimated devices are not placed on the layout. Clicking or > tells you that the auto AP placement is not able to place all the APs for the selected layout. Hence, you must manually place the remaining APs at the desired locations after you exit the wizard. It also asks you to use Auto Channel Allocation to minimize interference. 63 3Com ® AirProtect Planner User Guide WLAN Planning Wizard Figure 79. • Capacity Planning Summary – Passed? (Orange) If the Capacity Feasibility Check is ‘Failed!’, Planner also gives the potential reason for the failure. Figure 80. Capacity Planning Summary – Failed! Click to view the reason for failure. The ‘What‐If Scenario Analysis’ is useful to understand the reason for failure. Conditions for failure: ¾ If the expected capacity you specified is greater than the estimated capacity without Wi‐Fi interference, the planned capacity is not feasible. ¾ If the expected capacity you specified is greater than the estimated capacity with Wi‐Fi interference, the planned capacity is not feasible. Once you click in either of the above summary screens, Planner starts Auto Device Placement explained in detail in the next section. 6.2 Auto Device Placement Planner considers the following factors during Auto Device Placement. 64 3Com ® AirProtect Planner User Guide WLAN Planning Wizard • Whether there are any Area Polygons defined. ¾ If an Area Polygon is defined, Planner tries to place the calculated number of devices within the Area Polygon. ¾ If there are no Area Polygons defined, Planner places the devices on the layout at the calculated locations. After either of the above steps, if still more devices are left, then Planner displays a message that the remaining devices cannot be placed automatically and hence you can manually place the same at any desired location on the floor map. Planner shows a list of these devices in the Devices Library dialog box under Auto AP section. You can drag and drop these devices on the floor map. The device is of the same type as was selected during Device Selection in the WLAN planning wizard. 6.3 Auto Channel Allocation Due to limited available frequency spectrum for 802.11 WLANs, dense AP deployment often requires spatial reuse of frequencies. The strategy you chose determines the set of available channels. Channels are assigned to minimize interference. If you had placed some devices manually, or had selected cross floor devices using the Filter option; Planner considers interference from these devices during Auto Channel allocation to determine the best available channel for a device. Select either of the options for channel allocation strategy. Planner enables you to automatically allocate channels once the APs are placed on the floor map. Click from the Toolbar to invoke channel allocation strategy. The Channel Allocation Strategy dialog box appears. Figure 81. Channel Allocation Strategy Specify the channels you want to assign to the devices. • Non overlapping channels: These are channels that do not interfere with each other. For example, in the US, 2.4 GHz band offers three non‐overlapping channels – 1, 6, and 11. • All available channels: All channels are considered. For example, in the US 2.4 GHz band offers 11 channels. Using partially overlapping channels (for example, 1, 4, 7, 11) can improve overall WLAN capacity. 6.4 Estimating the Capacity At any given point, if you want to estimate the capacity, click estimated capacity for the layout. on the Toolbar. Planner displays a dialog box mentioning the 65 3Com ® AirProtect Planner User Guide Device Placement on the Layout Model Chapter 7 Device Placement on the Layout Model Device placement enables you to: • Plan the location of Sensors and APs on the layout model • Create ‘What‐If’ scenarios • Generate RF views to get visibility into the security exposure and RF coverage • Use various filters to get most relevant views 7.1 Planning Device Placement Planning Device Placement is divided into: • RF View Area • Status and Control Pane 7.1.1 RF View Area The RF View Area helps plan device placement for better network and coverage for the layout. Planner allows you to view the RF View Area in the ‘Full Screen’ mode. To do so, click Ctrl+F11. In the Full screen mode, the Toolbar, Status and Control Pane, and the Locations tree are rendered invisible, thus allowing you to use the complete screen to view the RF maps. Use the same command to return to the normal mode again. Figure 82. Planning Device Placement: RF View Area RF views (also called RF maps) are classified into three groups as shown in the following table. 66 3Com ® AirProtect Planner User Guide Device Placement on the Layout Model Coverage View Channel View Access Point Views Link Speed View Interference View Redundancy View SINR View Sensor Views Coverage View Threat View Calibration View Redundancy View Calibration Note: Whenever you shift from one tab of the RF view to another, Planner displays an Information message describing that tab. 7.1.2 Status and Control Pane The Status and Control pane is divided into two. One part appears one the Toolbar at the top of the screen, while the second part appears on the lower pane at the bottom of the screen. These are described in detail in the section Planning Device Placement: Status and Control. 7.2 Planning Device Placement: Views for Indoor and Outdoor Layout Placement of devices like APs and Sensors result in Indoor and Outdoor views. You can disable an AP by right‐clicking the AP and selecting Disable AP. Similarly, you can enable an AP by right‐clicking and selecting Enable AP. An enabled AP is represented as is represented as while a disabled AP is represented as . Likewise, you can enable/disable a Sensor too. An enabled Sensor while a disabled Sensor is represented as . This is just a viewing option for ‘What‐If’ scenarios. You can also view the coverage of a device on different floors using the Filter option in all the views except the Calibration View. In case of cross‐floor, if an AP or Sensor is visible on a layout but belongs to a floor above or below, then that AP or Sensor is represented with an UP arrow 7.2.1 or DOWN arrow . AP Coverage View This view displays color‐coded RSSI distribution over the current layout. It helps you plan for available signal strength at a specific location and check the availability of RF signal at different locations on the plan. This helps you ensure that all the regions in the plan have coverage from at least one AP. In case there is more than one AP covering an area on the layout, you can see the strongest signal strength in this view. Clicking at a point on the layout displays the predicted RSSI at that point in the Status bar. 67 3Com ® AirProtect Planner User Guide Device Placement on the Layout Model Figure 83. AP Coverage View: Indoor Layout Figure 84. AP Coverage View: Outdoor Layout 68 3Com ® AirProtect Planner User Guide Device Placement on the Layout Model Color Palette Customization: Double‐click the Color Index in the Status bar. This opens the Color dialog box where you can customize the colors. Note: You can customize the Color Palette in all the other views too. Figure 85. 7.2.2 Planning Device Placement: Customize Color Dialog Box AP Channel View This view displays the channel distribution over the current layout. The operating channel of the AP that provides maximum link speed at a location decides the channel value at that location. This view helps you decide the channel that should be used at a location for the best performance. This view displays the color‐coded channel of the AP showing the maximum downlink data rate at each point on the layout. Planner helps predict the AP to which a Client should associate for better signal strength and link speed. Visual display of channel distribution also helps you resolve channel overlap conditions. If you set the AP to a particular channel, you can see the color of the coverage area changed to the corresponding channel color. You can select one or any combination or all three protocols to view the channel coverage for those protocols on the layout. 69 3Com ® AirProtect Planner User Guide Device Placement on the Layout Model Figure 86. AP Channel View: Indoor Layout Figure 87. AP Channel View: Outdoor Layout 70 3Com ® AirProtect Planner User Guide Device Placement on the Layout Model 7.2.3 AP Link Speed View This view helps you plan for available downlink connectivity speeds and the choice of wireless Clients that should be used at various locations on the layout. It displays the maximum downlink data rate that a wireless Client can expect from a connection. It shows the 802.11 downlink connection speed available at each point on the layout. This view also helps you plan for minimum link speed at all locations on the current layout. Figure 88. AP Link Speed View: Indoor Layout 71 3Com ® AirProtect Planner User Guide Device Placement on the Layout Model Figure 89. 7.2.4 AP Link Speed View: Outdoor Layout AP Interference View This view displays the level of 802.11 channel interference at various locations on the plan. The interference is based on the signal strength of different APs, operating on the same channel, at that location. This view helps you plan for minimum interference to provide better network connectivity and better throughput for higher end user satisfaction. There are Interference View checkboxes at the bottom of the AP Interference View screen. • Co Channel: Select to show interference due to channels with the same frequency • Adjacent Channel: Select to show interference due to adjacent channels • Select both the checkboxes to view the total channel interference due to both Co‐Channel and Adjacent Channel channels. The color palette displays six levels of interference: Negligible, Very Low, Low, Moderate, High, and Very High. The Network Utilization drop‐down list at the bottom right corner of the screen allows you to choose Low, Medium, or High level of network utilization with which channel interference is to be computed. Network Utilization is a measure of the amount of 802.11 activity that is the traffic generated due to communication between 802.11 devices in the network. It also depends upon the channel of the communicating devices. Communication on a channel adds load to itself and to adjacent channels (in case of 802.11b and 802.11g) due to overlap in frequency spectrum of adjacent channels. Click
