1 1.1 NCL1170 Overview Introduction The NCL1170 is an intelligent, wireless Internet Protocol (IP) bridge/router that provides highcapacity 2.4 GHz connections between local- and wide-area networks via broadband radio links. Employing Direct-Sequence Spread Spectrum (DSSS) transmission techniques, the NCL1170 allows you to access the Internet at high speeds, extend Ethernet networks, and connect to remote locations without the ongoing costs of leased telephone or data lines.
1 NCL1170 Overview 1.2 2 Features • Flexible deployment—the NCL1170 can operate as either a bridge or router. In routing mode, you can set up the NCL1170 to use communications strategies such as Routing Information Protocol (RIP), and Dynamic Host Control Protocol (DHCP). • Ethernet compatibility—the NCL1170 allows users to connect with most Ethernet networks or devices.
1 NCL1170 Overview 1.3 About Spread-Spectrum Radio Technology Spread-spectrum communications systems differ from conventional narrowband communications systems because they use a much larger transmission bandwidth to send the same amount of information. There are two primary forms of spread spectrum—direct sequence and frequency hopping. The NCL1170 uses Direct-Sequence Spread-Spectrum (DSSS).

2 Network Considerations How you configure your NCL1170 depends on its intended role in your network. Before proceeding, answer the following questions: 2.
2 Network Considerations 2.1.1 Point-to-Multipoint In a typical point-to-multipoint application (see Figure 2) a designated master unit A, transmits and receives data among station units B, C, D, and E, which are programmed to communicate with each other only through their master unit. In this type of configuration, the throughput of unit A is shared among all stations.
2 Network Considerations 2.1.2 Point-to-Point In a typical point-to-point application, (see Figure 3), unit A communicates directly with unit B. The NCL1170 can perform this type of link in either bridging or routing mode. Ethernet Radio NCL1170 Ethernet NCL1170 A B Figure 3 Point-to-Point Application 2.1.3 Repeater In a typical repeater application, (see Figure 4), unit A communicates with unit B via back-toback NCL1170 units C and D, with different frequencies used for each leg of the path.
2 Network Considerations 2.2 Bridging and Routing Network Configurations 2.2.1 Point-to-Multipoint Bridging Network In a typical point-to-multipoint bridging network, (see Figure 5) unit A is installed as the network master, with units B, C, and D configured as stations, each defined by two network parameters: • Master ID—which must be the same as the Unit ID for A. • Unit ID—which must be added to the Remote Station List for A before it can be recognized as a network device.
2 Network Considerations 2.2.2 Point-to-Multipoint Routing Networks In a typical point-to-multipoint routing network, (see Figure 6), NCL1170 unit A is dedicated as a router, while NCL1170 units B through D are operating in Station mode as gateways to their respective networks. Ethernet NCL1170 Ethernet D Type: Unit ID: Radio Channel: Mode: IP Address - Ethernet: - Radio: Master ID: Station 103 1 Routing 13.0.2.103 10.0.2.
2 Network Considerations 2.3 Planning an NCL1170 Configuration Configuring each NCL1170 correctly is crucial to the proper operation of your network. Review the flowchart in Figure 7 before starting the configuration to ensure that you have the necessary information to configure the unit correctly. Record your configuration options for each unit in a configuration record similar to the one provided in Appendix F.
3 Installing the NCL1170 This section describes the steps required to connect and initialize the NCL1170 hardware prior to configuring the device as a bridge or router. WARNING! Antennas and associated transmission cable must be installed by qualified personnel. Failure to terminate the antenna port correctly can permanently damage the NCL1170. WaveRider assumes no liability for failure to adhere to this recommendation or to recognized general safety precautions.
3 Installing the NCL1170 3.1 Connecting the NCL1170 1. Attach an antenna or 50-ohm load to the antenna port at the rear of the NCL1170. Do NOT plug the NCL1170 to the power outlet until you have the antenna or load connected. NOTE: To prevent equipment damage, the NCL1170 is factory preset with its radio transmission capabilities disabled. However, as a general precaution, WaveRider recommends that you always connect the antenna or load before connecting to a power source.

5 Testing and Deployment This section describes the tests that you can perform before and after deployment to optimize the performance of your NCL1170: Before Deployment • radio connection (pinging) After Deployment 5.1 • signal strength (antenna alignment) • continuous transmit and receive • transmit and receive loopback Performing a Ping Test Use the Ping Test to verify that the NCL1170 is configured correctly and able to communicate with other bridges and routers.
5 Testing and Deployment WARNING! Antennas and associated transmission cable must be installed by qualified personnel. Failure to terminate the antenna port correctly can permanently damage the NCL1170. WaveRider assumes no liability for failure to adhere to this recommendation or to recognized general safety precautions. 2. Plug the NCL1170 back into the power source and at the terminal console keyboard, log into the NCL1170. 3.
5 Testing and Deployment 5.2 Optimizing Signal Strength 5.2.1 Running the Continuous Transmit (Tx) Test This test should only be used when setting up a Master and the first Station of a new network. The purpose of this test is to send a continuous stream of messages from an NCL1170 Master to a Station which receives and discards the messages, or to a spectrum analyzer for signal monitoring.
5 Testing and Deployment 7. When done with the antenna alignment, stop the test at the Master NCL1170. Type . 8. At the Station NCL1170, press any key to end the Radio PER output. NOTE: By default, a Master NCL1170 keeps track of the Radio PER of each Station. A Station does not track the Radio PER of another visible Station unless it is running the Continuous Receive test. Refer to section 5.2.2, Running the Continuous Receive (Rx) Test, on page 38.
5 Testing and Deployment 1. Ensure that the new Station NCL1170 has been configured and tested. 2. Deploy the Station and connect the antenna. WARNING! Antennas and associated transmission cable must be installed by qualified personnel. Failure to terminate the antenna port correctly can permanently damage the NCL1170.

5 Testing and Deployment 5.2.3 Performing the Transmit/Receive Loopback Test This test should only be used when setting up a new network. The purpose of this test is to ensure that the Master NCL1170 can “see” the Station. It also determines the quality of the links between Master and Station. The test originates at the Master NCL1170, repeatedly sending test packets to the Stations. A Station recognizes these as test packets from the Master and echoes them back to the Master.
5 Testing and Deployment The information received from Radio PER during the Transmit/Receive Loopback test will be similar to the following output. The following output is from a Master (unit ID 1) communicating with two Stations (unit IDs 2 and 3).
6 System Reporting and Diagnostics After an NCL1170 has been configured, tested, and deployed, you can generate on demand reports about its performance in key system areas: 6.1 • Receive Signal Strength Indication (RSSI) • Radio Packet Error Rate (PER) • Interface Statistics Radio Receive Signal Strength Indication (RSSI) Radio RSSI calculates the average and peak receive signal strength values based on factory set threshold (floor) value. This value can be reconfigured by the user.
6 System Reporting and Diagnostics 6.2 Radio Packet Error Rate (PER) Radio PER can be displayed at any time, including during tests. See Chapter 5.2, Optimizing Signal Strength, on page 37 for other tests that use Radio PER statistics. To display the current Radio PER for an NCL1170 during normal operation, type or . Table 1 defines how to interpret the Radio PER output. At a Master NCL1170, you will receive output similar to the following.

Table 10 NCL1170 Network Terminology Term Definition Address Resolution Protocol (ARP) The layer below the IP layer; maps the IP and MAC addresses together. Bridge A device that connects and passes packets between two network segments. A bridge operates at the MAC layer. A bridge filters or forwards an incoming frame based on the MAC address of the frame. A learning bridge listens to traffic on its interfaces and maintains a table of addresses. See also Router.
Term Definition Media Access Control (MAC) address The 6-byte low-level hardware or physical address of an Ethernet device. Radio Channel A 22 MHz wide RF channel with a center frequency specified in Appendix C. In any given network, all NCL1170s must operate on the same radio channel to communicate. Radio Type This parameter specifies the role of the NCL1170 in the radio network. Each NCL1170 is classified as either a master or a station.

Appendix D NCL1170 Antenna Recommendations The NCL1170 has been certified for use with Omni, Patch, Yagi, and Dish antenna types. The table below includes examples of each of the recommended antenna types, as well as their associated maximum antenna system gain. Table 11 NCL1170 Supported Antennas Antenna Type Manufacturer Model Number Maximum Antenna System Gain Omni Mobile Mark OD9-2400 9.0 dBi Patch Til-Tek TA-2408 10.6 dBi Yagi Astron 928-4 10.1 dBi Dish Til-Tek TA-811 10.
For example, with a Yagi antenna system, 10 m of cable, a surge protector, and a bandpass filter, you would calculate the following antenna system gain: Antenna gain: Insertion loss: - cable: - surge protector: - filter: 12.4 dBi 4 dB 0.2 dB 1.1 dB The total insertion loss is 5.3 dB, which gives an antenna system gain of 12.4 dBi minus 5.3 dB, or 7.1 dBi. Since the system gain is lower than the maximum antenna system gain of 9.1 dBi, this antenna configuration is valid.
Appendix E NCL1170 Specifications The followiing tables list the technical specifications for the NCL1170 (FCC/IC RF Regulatory Domains).
