1 7signal solution 1 7signal Sapphire provides you a new way to continuously and automatically measure the health and quality of a wireless network from the user's perspective. Companies and their business processes are becoming increasingly dependent on the performance and service quality of their wireless networks. Thanks to the Sapphire solution, companies can integrate the quality management of wireless networks with their existing IT and communications technology services.
1 7signal solution 2 7signal Sapphire Carat User Guide Release 5.0 Figure 1: 7signal Sapphire installation The system components are described in chapters 2–6. The remaining chapters describe the management software. The result viewing and reporting tool (Analyzer) is described in its own user guide. 7signal Solutions, Inc., 526 S. Main Street, Akron, Ohio 44311, USA, 855-763-9526, info@7signal.com, www.7signal.
2 7signal solution 3 2.1 Sapphire Eye Sapphire Eye is a monitoring station for WLAN environments. Unlike a common access point or client, the Eye monitoring station uses advanced broadband antenna technology, which creates an exceptionally large coverage area. Consequently, one Eye can monitor several access points, or WLAN cells. The typical number of monitored cells is 5–8. There are two monitoring station variants: the Standard Eye and the Indoor Eye.
2 7signal solution 4 A monitoring station conducts both passive and active measurements in a WLAN environment. The passive measurements consist of listening to data traffic that uses the IEEE 802.11 protocol and of general analysis of the radio frequency spectrum in the coverage area. Passive measurements have no effect on the functionality or utilization rate of the target network, or the effect is very small (probe request transmissions).
3 7signal solution 5 With the Sapphire Carat management tool, you can manage the Sapphire Eye and Micro Eye monitoring stations, run interactive and real-time measurements, configure and manage automatic measurements, and generate reports of the measurement results. The reports shows measurement results in tables and charts. Sapphire Carat stores the profiles used in the automatic testing of the monitored network, and the network’s access rights information.
4 7signal solution 6 The role of the Sonar test server in 7signal Sapphire is to emulate one of the customer’s production servers. Sapphire Eye or Micro Eye connects to Sonar to measure QoS provided by the network. Measurements are performed in both directions (uplink and downlink). Uplink means traffic from end-user device (e.g. Eye) towards network (e.g. Sonar). Downlink means traffic from network towards the end-user device.
5 7signal solution Sapphire Analyzer is the performance and QoS analysis tool in the 7signal solution. Analyzer cannot be used to control Sapphire’s functions and measurements themselves. Analyzer makes the network’s key performance indicators (KPIs) available at a glance, or in more detailed form for a given time period. Starting from release 5.0, Analyzer also provides new features called “Automatic Analysis” and “Automatic Optimization”.
6 7signal solution 8 The Carat user interface (GUI) is a stand-alone java client. The purpose of the Carat user interface is to configure and manage the Sapphire solution. Several users can access and configure single Carat simultaneously. 6.1 Menus 6.1.1 Navigation The menu contents are dynamic based on context, user access rights and the current license. Table 1: Management GUI menus Menu Description File Log in / log out, lock the session, and close the application.

Database maintenance Start automated testing Stop automated testing Automated tests management Import… Export… Window Refresh the main window of the user interface. Refresh Help Read user documentation and general information about the system installation.
6 7signal solution 10 A Sapphire Eye or Micro Eye monitoring station always belongs to a service area. In this menu, you can perform Eye level tests, bind and unbind test profile to/from the Eye, report change events for this Eye and modify Eye connectivity properties (change IP configuration, SSH password etc.) Eye Wireless network This menu describes the target network, which can be located in one or more service areas. A service area can contain several target networks.
7 7signal solution 11 The access rights and user management heavily relies a group-based model. The group is the starting point: every user belongs to one of the groups and the group determines the access rights of any given user. The technical details and management instructions are in the next section. Any objects in the system – Eyes, Sonars, topology elements such as Organizations and Locations – belong to some administrative group.
7 7signal solution 12 3. Create a new configurator user to the Configurator group. Use a descriptive name, f ex LocalConfigurator1. 4. Continue using Sapphire. All other configurations related to network topology, test profiles, WLAN network keys etc. should be made by the user LocalConfigurator1 to enable proper operation of the automated object access rights management system. Some top-level operations for Solution Administrator are explained right below 7.
8 7signal solution 13 User management in 7signal Sapphire is based on user groups. A user's access rights in the system derive from the user group that the user belongs to. A user may belong to one or more user groups. In addition to normal user management the Sapphire system supports user group specific view virtualization. The system can be configured so that different user groups have access to different objects that have been created into the system.
8 7signal solution 14 The Sapphire system supports three elementary access levels for user groups: Reporter, Configurator and Administrator. Access rights are inherited from lower to higher levels: Reporter users only have their own level’s access rights, Configurator users have reporter level rights plus additional rights granted by their configurator level, and Administrator users have all rights.
8 7signal solution 15 A new user group can be added into the system in three different ways: 1. As a new root group under which to start creating a new user group hierarchy. 2. As a subgroup to an already existing user group. 3. As a symbolic (referencing) group for an already existing group.
8 7signal solution 16 1. Log in as an administrator group user 2. Open the user group and user management dialog by clicking "Manage | Users and Groups" from the top menu bar 3. Right-click on a group that satisfies the removal criteria and select "Remove" from the pop-up menu 8.5.6 User Group status In certain situations it may be desired to inactivate some user group. An inactive user group has no access rights in the system.
8 7signal solution 17 A new user can be added by right-clicking on the user group that the user is to be added into and selecting "Add user" from the pop-up menu. Steps to create a new user: 1. 2. 3. 4. From the top menu bar select “Manage | Users and Groups” to open a pane on left Right-click the relevant group to get a submenu Select “Add user” to open a pane on right Enter the relevant user information a. Username: login name for the user b. (optional) Alias: alternative name for the user c.
8 7signal solution 18 1. Log in as an administrator group user 2. Open the user group and user management dialog by clicking "Manage | Users and Groups" from the top menu bar 3. Right-click on the desired user and pick "Edit" from the pop-up menu 4. Change the desired parameters 5. Save changes by clicking "Save" 8.6.5 Removing Users A user can be removed by right-clicking on him/her and selecting "Remove" from the pop-up menu. An example of removing a user: 1. Log in as an administrator group user 2.
9 7signal solution 19 Network topology is defined in Carat to reflect geography and organization and help with reporting necessary entities separately. Network topology consists of organizations, locations, service areas, Eyes and managed access points. 9.1 Choosing networks to be monitored 9.1.1 Organization Sapphire can simultaneously manage networks in several independent organizations. A company or other organization can have many separate locations.
9 7signal solution 20 Location is used to define the network’s location in a precise or descriptive way. A location might be a city, a part of the city, a building, or a single floor in a building, depending on the coverage area of the organization’s network. A small organization might have only a single location, an office. On the other hand, a large organization might have several locations, in different cities, or a single overall location, such as “Europe,” under which countries and cities etc.
9 7signal solution 21 7signal Sapphire considers a hidden network to be a property of certain Organization. The network scans are based on listening and actively requesting beacon information on the Service Areas. The hidden networks shall not actively transmit beacons nor respond to requests with partial information only. Due to this the various scans - including the initial scan in 7signal Sapphire do not capture hidden networks.
9 7signal solution 22 7signal Sapphire Carat User Guide Release 5.0 Figure 6: All Wireless Networks view The pane "All Wireless Networks" shows all defined networks. By choosing the network it is possible to change the current data. Button "Remove" deletes the network and the related information from the system. 9.1.4 Meru networks Virtual Cell and Virtual Port technologies used in Meru networks requires additional configuration steps.
9 7signal solution 23 7signal Sapphire Carat User Guide Release 5.0 Figure 7: Selecting Meru mode In order to set correct mode: 1. Locate Meru network in Topology tree 2. Right-click and select “Edit” 3. Select the correct Meru operation mode by selecting a checkbox. 4. Click “Save” button. Access point naming As the access points cannot be distinguished by their BSSID in Meru networks, serial MAC address, Meru access point ID, and radio index of the access point are used.
9 7signal solution 24 7signal Sapphire Carat User Guide Release 5.0 Figure 8: Meru specific properties In Sapphire Analyzer, the same information can be seen in Info pop-up window. Active and passive measurements All active measurements of Meru networks work similarly to measurements executed for standard networks. Passive measurements are more problematic.
9 7signal solution NWBandEyeClient NWBandEyeAntClient 9.1.5 Avoiding band selection/steering Some WLAN vendors have implemented different kinds of methods to guide (or force) clients on a certain WLAN band, typically from 2.4 GHz to 5 GHz, which is less crowded. As monitoring stations run measurements on both bands, these band steering/selections will affect negatively to test results, usually resulting attach failures.
9 7signal solution 26 All networks managed by Sapphire are displayed in the Network topology. Networks can be deleted on the organization level. To delete a network from the Network topology: 1. From the Network topology, select the organization containing the wireless network you wish to remove 2. Right-click the organization and select “View wireless network” – then the “All Wireless Networks” view is displayed in the right-hand pane 3. Select from the list the network you want to remove 4.
9 7signal solution 27 7signal Sapphire Enterprise extends this functionality such that all access points or networks within the service area can have their own allowed and forbidden channels. This allows Sapphire to monitor the channel configuration in several networks, and to obtain information on other networks that use channels in unexpected ways. One obvious area of application for channel configuration is office hotels, which have several small wireless networks that can interfere with each other.
10 7signal solution 28 10.1 States of Monitoring Stations The Eye unit may be in an inactive state. This happens if there is no network connectivity to the monitoring station when a monitoring station is being added to the system. Also, an active monitoring station may be turned inactive. This allows exceeding the number of monitoring stations limited by the license. Only active monitoring stations may run the tests but the topology may contain unlimited number of inactive monitoring stations.

16 7signal solution 63 The IEEE 802.11e standard defines eight traffic classes. Most mission-critical access points support this standard. Traffic classes are becoming more and more important, especially on account of wireless VoIP. 7signal Sapphire Enterprise supports the 802.11e standard. Active tests can be configured to have a traffic class.
17 7signal solution 64 The tests are grouped into passive listening tests and active tests in the radio network. There are two ways to run tests in Sapphire Carat: user-initiated (manual) tests to locate a fault and automated tests for continuous monitoring and collecting of measurement results. You can run the tests from a hierarchical tree. Test menus are accessible by right-clicking a monitoring station or an access point. 17.
