3 Installing a SkyAccess DualBand This chapter provides instructions for planning and performing the physical installation of a SkyAccess DualBand. NOTE Professional Installation is required to ensure that the proper antenna is employed such that FCC transmit power limits for this equipment are not exceeded. Planning the installation In a typical wide area wireless mesh network, a SkyAccess DualBand would be installed on a utility pole or the roof of a building.
The site survey should include an RF scan to identify available frequencies. Check the preferred frequency at all locations; a frequency that’s clear at one location may be crowded at another. Frequency planning is a critical factor in planning and implementing a wireless mesh network. The site survey process should be ongoing. To verify that a site is relatively free of interference, site audits should occur every 6 to 12 months, scheduling regular maintenance visits to coincide with the site audits.
Figure 3. Connecting CAT5 cable to the SkyAccess DualBand 5 GHz Make sure the fit is snug so that the cable does not interfere with the weather gasket. 2 Insert the weather gasket and secure the metal cover. Press the CAT5 cable into the gasket and insert the gasket into the housing, taking care not to twist or place unnecessary force on the RJ-45 connector. Fit the metal cover over the weather gasket and secure it with the four machine screws supplied in the accessory kit.

4 Attach tie wraps to the neck of the weather gasket and tighten them so that they slightly depress the neck. Figure 5. Attaching tie wraps to the gasket neck 5 GHz The tie wraps provide relief from cable strain and ensure a fully weatherproof seal. Powering on the SkyAccess DualBand Prior to mounting the SkyAccess DualBand, power on the unit to use the onboard LEDs to facilitate optimal placement. 1 Connect the SkyAccess DualBand to the power supply, as follows: a.
Figure 6. Providing power to the SkyAccess DualBand 5 GHz 2 Check the LEDs on the SkyAccess DualBand. If the connections are correct, the power LED (labeled “PWR”) and the WAN activity LED (labeled “WAN Act”) on the SkyAccess DualBand will illuminate. The WAN Act LED should blink and turn off, but the PWR LED should remain lit. Figure 7.
Optimizing location After powering on the SkyAccess DualBand, use the device’s LEDs to identify the optimal location for mounting—a location where it can easily acquire a signal from the wireless mesh network and quickly create links. Confirm signal acquisition Position the SkyAccess DualBand near the intended mounting location and watch the WAN Act LED for activity. The LED starts to blink when it has acquired a signal from the network and is attempting to set up a connection.
NOTE To optimize your SkyAccess DualBand installation, ask your network administrator (at the Network Operations Center) to measure signal strength on the node to which the SkyAccess DualBand has established a link. For more information on LED states, see Table 1.

Mounting the SkyAccess DualBand After determining an optimal location the SkyAccess DualBand can then be mounted in accordance with the procedure below. Before mounting the device, disconnect the CAT5 cable from the power injector to power down the device. 1 Connect the 2.4 GHz antenna. To provide Wi-Fi connectivity, the SkyAccess DualBand requires attachment of the 2.4 GHz antenna included with the device. Screw the antenna onto the standard N connector on the back of the SkyAccess DualBand. Figure 8.
2 Use the supplied clamps to secure the SkyAccess DualBand to the pole; then loop the Ethernet cable around the mounting pole and secure it with tie wraps. Figure 9. Securing the SkyAccess DualBand Tighten the bolts securely on the mounting hardware. 3 Reconnect the CAT5 cable to the port on the power injector to restore power to the SkyAccess DualBand.
Connecting to the wireless network After mounting the SkyAccess DualBand, set up a connection to the wireless network via a local computer or LAN. Once connected, a subscriber can use the wireless network to gain access to Internet services and applications. Connection to the SkyAccess DualBand is accomplished with Ethernet, or through the onboard access point to establish a wireless connection.
Figure 10. Connecting a SkyAccess DualBand to a computer Connect to the wireless network via a WiFi connection 1 From a Wi-Fi/WPA-PSK capable computer within operating range of the access point, open the Network control panel and set up a wireless connection with the IP address 192.168.0.10 and Netmask 255.255.255.0. 2 From the Network Connection control panel choose the default SSID provided with the SkyAccess DualBand— “SkyAccessDualBand”. 3 At the password prompt, enter “publicpublic”.
Configuring the SkyAccess DualBand A SkyAccess DualBand requires two different configurations: a network configuration that allows it to operate on the wireless mesh network, and an access point configuration that allows the device to support local wireless connections via Wi-Fi. For information about configuring both the device and the access point, see the document “SkyPilot Network Administration”, available in electronic format from the SkyPilot website at www.skypilot.com/support/.
A Accessing SkyAccess DualBand Command-Line Interfaces This appendix describes how to access the command-line interfaces that SkyPilot SkyAccess DualBand provides for provisioning and troubleshooting. You can connect to two different interfaces on the SkyAccess DualBand: an interface with the device that operates as a node on the wireless mesh network, and a separate interface with the access point that extends Wi-Fi connectivity to subscribers.
Telnet to the default IP address of the SkyAccess DualBand (192.168.0.2). 5 Log in by entering the password at the command prompt. (The default is public.) Figure 11. Example Telnet login After making an Ethernet connection to the SkyAccess DualBand, you can manage and troubleshoot the device using a wide range of commands available through the command-line interface. For detailed descriptions of the commands, as well as sample output for many of them, see SkyPilot Network Administration.
The access point component of SkyAccess DualBand ships with the default IP address 192.168.0.3. 2 Open the connection to the access point. From your Telnet application, open a connection to the access point. 3 Log in by entering the default user name (admin) and password (public) at the command prompt.
