SL-TVWS-1001-User Manual and Installation Guide Figure 1 TVWS GUI Application Installation On Successful installation a shortcut icon will be created on Desktop and configuration files will be copied under c:\Users\\.saankhya\.atconfig. Follow the steps indicated in Figure 2 to start the TVWS GUI Application.
SL-TVWS-1001-User Manual and Installation Guide 6) BS Installation Meghdoot BS should be installed by an authorized professional only. Installation and operation of the devices by persons other than the professional installers might cause permanent damage to the device and malfunction. Saankhya TVWS devices have 3 ports – 2 for antenna and 1 for PoE as shown in Figure 4. These devices are mounted on a pole with the help of clamps and screws provided with standard shipment.
SL-TVWS-1001-User Manual and Installation Guide Figure 4 Saankhya TVWS Device Notes: 1) The devices should be mounted vertically with the PoE port facing earth in order to reduce wind resistance 2) Clamps should be secured firmly in order to avoid any injury or damage resulting from the box slipping down the pole 7) BS Configuration Make sure that all the connections are done as described in Section 6) Launch the TVWS GUI Application by double clicking on the application icon.
SL-TVWS-1001-User Manual and Installation Guide Database services might be required as per the regulations of the country where TVWS device is being operated. One needs to configure the URL and the API-key provided by the service provider before accessing the database If you operate in a region where database services are not mandatory, this step can be skipped. Please ensure that in such a case DB query option is disabled on TVWS. On launching the gui_app_v3.
SL-TVWS-1001-User Manual and Installation Guide Figure 6 Adding WSDB provider 7.2 Provision the BS and CPE devices To use any device (BS or CPE) it should first be provisioned into the system. There are several parameters which need to be specified. Incorrect provisioning will result in the WSDB rejecting the requests and failure to operate the device.
SL-TVWS-1001-User Manual and Installation Guide Figure 7 Provisioning Base station with TVWS GUI On successful provisioning, a message is displayed in the log window at the bottom. Also ensure that the DB query parameter as shown in above figure is set to enabled. 7.3 Discover BS devices After provisioning, we need to connect to the device and apply configuration and start the radios. The devices can be discovered if they are on the same IPv4 subnet as that of the PC running the TVWS Application.
SL-TVWS-1001-User Manual and Installation Guide On successful connection to the device, the following screen appears please note the 3 important points marked on the screenshot Figure 9 TVWS BS Opening Screen Notes: 8) All devices are shipped in ‘Installation’ mode. In this mode, the device radios are not turned on unless user applies a valid configuration 9) On successful application of configuration, device moves to ‘Operational’ mode. No parameter change is allowed in this state 7.
SL-TVWS-1001-User Manual and Installation Guide Figure 10 Location Data source selection Configuration files are provided for devices with following naming convention: ______.
SL-TVWS-1001-User Manual and Installation Guide Figure 11: List of available configuration files Before applying the configuration to the device (using the ‘Apply’ button as shown in Figure 9) please double check the following: ▪ ▪ ▪ ▪ ▪ TVWSDB Query is set to Enabled The location co-ordinates are correct or if using GPS, it is in locked state (using the LED status) The Antenna Height above ground level (AGL) The range of channels is set appropriately.
SL-TVWS-1001-User Manual and Installation Guide Figure 12 Loading Configuration from INI files Once the configuration is applied, the TVWS Application queries the WSDB for available spectrum and the same is presented to user for selection as shown in Figure 13.
SL-TVWS-1001-User Manual and Installation Guide Figure 13 Frequency Selection for Base Station After selection of suitable frequency, the radios are turned on which can be seen from the items marked in figure below Figure 14 Successful Triggering of Base Station into Operational Mode Copyright Saankhya Labs Private Ltd, Bangalore
SL-TVWS-1001-User Manual and Installation Guide Notes: 1) TVWS Base Station GUI application acts as proxy for all the devices connected to it. It must be kept running all the time 2) TVWS Base Station GUI application will prompt user for frequency selection only in Installation Mode. In Operational mode it selects the last selected frequency on subsequent interactions with the WSDB. If this frequency is not available, it selects the first frequency available in the range of operation. 7.

Notes: 1) Switching to installation mode will cause the BS to reboot 8) CPE Installation Dhaval CPEs should be installed by an authorized professional only.
SL-TVWS-1001-User Manual and Installation Guide Installation of the CPE devices is identical to that of the Base station devices except for connecting the laptop directly to the Ethernet cable. In case a WiFi router is to be used, the Ethernet cable from CPE should be connected to the WAN port of WiFi router. The CPE is configured to act as a router and assign IP addresses to the devices connected to it. The IP addresses assigned by the CPE are in subnet 192.168.88.0/24.
SL-TVWS-1001-User Manual and Installation Guide Figure 19 CPE Login Screen 9.2 Configure CPE device CPE configuration files naming convention is similar to BS configuration files. Refer Section 7.4 for the naming convention and select appropriate file as indicated in Figure 20. Figure 20 Selecting CPE configuration On coming back to main screen, enter the location information manually or select GPS as source. Also enter the antenna height above ground level (AGL) and frequency bands to scan.
SL-TVWS-1001-User Manual and Installation Guide 3) Depending on the Bandwidth selected, the frequency bands will increment by multiples of the bandwidth Figure 21 Additional CPE configurations 9.3 Scan for Available Networks On applying the configurations above, CPE starts scanning for available networks. It might take a while depending on the range of scan. For entire TV band it might take as long as 15-20 minutes.
SL-TVWS-1001-User Manual and Installation Guide 4) If there are no networks found the CPE will reboot on its own 5) After moving to operational mode if CPE loses the network it will perform scan for the last registered band and then full range of frequencies automatically. 9.
