    Notice: The changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. IMPORTANT NOTE: To comply with the FCC RF exposure compliance requirements, no change to the antenna or the device is permitted. Any change to the antenna or the device could result in the device exceeding the RF exposure requirements and void user’s authority to operate the device.

  • Page 10: Hardware Installation

    Hardware Installation 2-4 Hardware Installation The Orion-900, 900MHz ISM band radio is a radio device, so it is susceptible to common causes of interference that can reduce throughput and range. Follow these basic guidelines to ensure the best possible performance: If there is any other 900MHz RF device deployed in the area, try to set the channel to one that does not overlap the interferer.

  • Page 11: Chapter 3 Antenna And Rf Tutorial

    Configure and test the Orion-900, 900MHz ISM band radio indoors first before installing and mounting antennas. The Power Over Ethernet Injector is not a waterproof unit, and should not be exposed outdoors without protection or you may void your warranty.

  • Page 12: Site Selection

    Gain “Gain” specifies the receive and transmit performance of any antenna compared to a standard omni-directional antenna (“spherical radiator”). The objective of a directional antenna design is to achieve gain, improving sensitivity and effective radiating power to increase range or data rate. Gain is measured and stated in decibels, abbreviated dB.
  • Page 13 For this reason, a proper antenna site must meet the following criteria: 1. For optimum performance at maximum range, there must be a clear line-of-sight path among all antennas that communicate directly with each other. At shorter ranges, some degree of obstruction may be tolerated, but performance in the presence of obstruction is difficult to predict.
  • Page 14 A reasonable approximation of the radio horizon based on antenna height can be obtained from the graph below. (Note that this graph does not take atmospheric effects into account.) To use the graph, set a straight edge so that it crosses the height of one of the antennas in the column on the left and the height of the other antenna in the column on the right.
  • Page 15 Using short cables to connect the radio to the antenna reduces signal losses. The below table shows loss per 100 feet (30 meters) at 2.4 GHz for typical antenna cable types. Loss at 900 MHz for LMR Equivalent Coaxial Cable Types Cable Type Loss per 100 ft.
  • Page 16 Connector Loss Loss is introduced with each pair of cable connectors. Attenuation losses of some standard cable types are shown in the following table: Connector type Loss per connector Most RF Connectors 0.25 dB The loss of each pair of connectors on all cables must be included to determine the total signal loss (attenuation) between the antenna and ODU.

  • Page 19 Basic Setup The Wireless bridge Name is used to give a name to your Wireless bridge. This will enable you to manage your Wireless bridge more easily if you have multiple radios on your network (note: this is not the SSID of the radio). Ethernet Data Rate: you can choose the Ethernet data rate you require.

    4-2 Wireless Setup Wireless Setup / Radio Settings Operating mode: There are 3 operating modes that can be selected in this field. In a point to point environment where there are only two radios, Peer to Peer is recommended because it works more efficiently, but one radio as a base station and the other as a CPE works as well.
  • Page 22 Site Survey: Site survey only works in CPE mode, which can scan for Base stations. See above recommendation (Operating mode). The systems is optimized when the signal strength is higher that -70 dBm. A lower signal of -71dBm or lower may cause the link to fail. Base Station ID: Commonly called SSID, this station ID works only in Base station to CPE mode.
  • Page 23 Bandwidth: Set the Bandwidth of the radio. The options are 20MHz / 10MHz / 5MHz. Different bandwidth selections have different throughputs. Below is the list. Bandwidth Throughput 5MHz 5.5Mbps 10MHz 10Mbps 20MHz 20Mbps SEE OUTPUT POWER AND SPECIFICATION CHART FOR THE ABOVE SETTINGS. Bandwidth, output power and channel selection are all affected during the programming process.
  • Page 24 Time Slice: set the time slice of the VQOS / TDM. This function will allow a certain amount of time (in ms) that data will transmit to each user before it moves to the next user. This is a repetitive cycle.

Multi-point to multi-point Bridge: To activate the Multi-Point to Multi-Point Bridge mode follow the exact steps as above. However, in this case you would enter the MAC address’s of other radios within your network.
