    2.0 QUICK-START INSTRUCTIONS 2.1 Connecting to the Device Manager The Mercury transceiver contains a built-in web server, known as the Device Manager, for configuration and diagnostics. Each transceiver needs to have some basic configuration parameters set before placing the unit in service. To start the Device Manager, connect an Ethernet cable from the Mercury to the PC used for configuration.

    2.2 Configure IP Address and Identity The IP Address of the unit is configured on the Configuration - IP & page. The IP address and netmask should be set according to Networking the network configuration defined by the system administrator. Note that if the IP address is changed, the web browser session will need to be re-started with the new configuration.

  • Page 17: Setup For Maximum Throughput

    Setup for Maximum Throughput To demonstrate maximum throughput, several configuration changes must be made. In addition, the link needs to be cabled according to Figure 7, with a strong signal, that is, above -70 dBm. If necessary, the link attenuation should be adjusted to reach the desired RSSI level. The transmit power of the Base Station should be reduced to 10 dBm to ensure that the Subscriber only receives the signal through the cables and not directly from enclosure to enclosure.

    Authentication Authentication is the process by which one network entity verifies that another entity is who or what it claims to be and has the right to join the network and use its services. Authentication in wireless SCADA networks has two primary forms: User Authentication and Device Authentication.

The Base Station then continues the PKM protocol to further derive keying material that is used to secure transmissions between the Base Station and the Subscriber. The Subscriber must be configured with X.509 certificates that are appropriate for the Public Key Infrastructure (PKI) in which they are deployed.

    This determination is made based on the SNR and Packet Error Rate (PER). GE MDS sells antennas that are dual-polarized for MIMO applications. This includes sector antennas for Base Stations and panel antennas for Subscribers. Each antenna has two feed lines, one for the vertically polarized element, and one for the horizontally polarized element.

    WiMAX provides five types of service: Unsolicited Grant Service Service Types (UGS), Real-time Polling Service (RTPS), Non-real time polling Service (nRTPS), Enhanced Real-time Polling Service (eRTPS), and Best Effort (BE). The characteristics and typical uses for service type are given in Table 4 below.

    QOS Example: Prioritizing a Data Flow In order to prioritize one traffic flow over another, the service flow priority should be used. In this example, there are two VLANs on the trunk at the Base Station. Suppose the user wants to treat traffic on VLAN 5 as higher priority than traffic on VLAN 6 in the event of heavy network traffic or congestion.
  • Page 38 NOTE: When using QoS with a subscriber-specific MAC address, an uplink and downlink service flow must be created. Otherwise, no data will pass over the air. The dialog box shown in Figure 20 shows the uplink service flow for VLAN 6. Figure 20.

    Although these antennas may be more costly than omnidirectional types, they confine the transmission and reception pattern to a com- paratively narrow lobe, that minimizes interference to (and from) stations located outside the pattern. • If interference problems persist, try reducing the length of data streams.

  • Page 64: Antenna Heading Optimization

    1. Place a directional wattmeter between the radio ( connector) Procedure TX/RX and the antenna system. 2. With the transmitter keyed, measure the forward and reflected power on the wattmeter. Reflected power should be no more than 10% of the forward power. Record these readings for future refer- ence.
