    1 PRODUCT DESCRIPTION 1.1 Radio Overview The AR24027 Wireless Ethernet Bridge is a license free radio that can be used to bridge Ethernet LAN’s (Local Area Networks) across distances ranging from a few hundred feet to 50 miles (80 Km) and beyond.

  • Page 9: Radio Components

    AR24027 Operator’s Manual The AR24027 can be configured over a local serial interface or over the Ethernet using an “Ethernet console” program provided by Afar. Once a unit is configured with an IP address you can also configure and monitor the unit using Telnet or SNMP. The radio firmware, in non-volatile memory, can also be updated remotely.

  • Page 16: Theory Of Operation

    2.1.1 Firmware builds You may use the AR24027 to deploy a wireless network in various topologies, including Point-to- Point (PtP), Point-to-Multi-Point (PmP) and also a Linear Network topology. The radio non-volatile memory can hold various programs at any given time but only one program can be running at a time (use the >directory command to view all the files loaded into the radio memory).

  • Page 17: Point To Point Topology

    (from hub to remotes) and the second phase for inbound transmissions (from the remotes to the hub). Total cycle time is fixed at 20 ms. However the AR24027 provides great flexibility in determining the “split” between the outbound and inbound phases.

  • Page 18: Automatic Remote Association

    AR24027 Operator’s Manual When the remote radios transmit they include a bandwidth request parameter, informing the hub of how much inbound traffic they have queued up. The hub allocates slots to the remotes based on this information. On a given cycle, each remote may be allocated zero, one, or several contiguous slots to transmit.

  • Page 19: Co-Located Radios Self-Interference

    • Lower the transmit power of the interfering radio. These approaches are limited and, at most, may allow you to co-locate three of four radios. The Afar PULSAR technology implements a synchronization scheme that completely eliminates this self- interference allowing you to co-locate a much large number of radios. This is explained in the...

  • Page 20: Pulsar Network Synchronization

    2.3.3 PULSAR Network synchronization The AR24027 can be operated in a fixed TDD mode, where the complete cycle is divided into fixed length outbound and inbound phases. You can specify this cycle split to be 50/50 or asymmetric. When you co-locate multiple devices you must choose a fixed split and it must be the same for all the co-located radios.

  • Page 21: Heartbeat Packet Suppression

    AR24027 Operator’s Manual Make sure that all radios have the tdd sync-mode set to auto. If you follow the above guidelines the radios will spread the synchronization across the network and completely avoid self-interference. At any device use the “>show” command to find which radio is the source for the heartbeat at that site.

  • Page 22: Synchronization With Netcrossing Gateways

    The Afar NetCrossing Gateway (NXG) devices convert between a synchronous serial data stream and Ethernet packets. They can be paired with the AR24027 to establish wireless point to point serial synchronous links. When you have multiple of those links and need to co-locate radios, the gateways can participate in the heartbeat negotiation and site synchronization.

  • Page 23: Ethernet Bridging

    AR24027 Operator’s Manual is the synchronization source. In fact any gateway can be added or dropped without affecting the cycle timers of the remaining gateways. You must configure the three left radios as the “hub” for their RF links. Each of these three radios detects the presence of the respective gateway, which becomes the source of its heartbeat over the Ethernet.

  • Page 24: Packet Priorities

    Starting with the highest priority the packets are classified as follows: • NetCrossing Gateways Serial packets: These are SNAP encapsulated packets containing synchronous serial data generated by the Afar NetCrossing Gateway devices. • High-Priority: These includes network management packets for “ECON” command sessions, and also IP packets with a value in the “Type-Of-Service”...

  • Page 29: Earth Grounding

    AR24027 Operator’s Manual 3.2.2 Earth Grounding For an outdoor installation you must provide a solid ground connection between the AR24027 metal enclosure and the Earth ground. This will minimize possible damage due to static buildup or nearby lightning. In locations where it is warranted, you may also want to install a lightning arrestor device at the N type connector of the radio leading to the antenna (Afar part no SUP-0201).

  • Page 30: Power/Ethernet Cable

Cautions When using the anti oxidizing paste read and follow the instructions and warnings for the selected product.

  • Page 31: Antenna Installation

    These limits are described in the following sections. The AR24027 is typically attached to a pole (with the clamp provided) with the antenna connectors facing up. For optimum performance the radio must be mounted in close proximity to the antenna with a cable run typically under 2 meters (6 feet).

  • Page 32: Antenna Alignment

    Since in many applications the antenna is on a tower where it is not practical to have a terminal nearby, the AR24027 has an additional “antenna alignment aid” available at the outdoor unit. This feature uses the three pin “Auxiliary port” connector to output an audio signal with a pitch proportional to the receive signal strength.

  • Page 33: Spectrum Analysis And Channel Selection

    In addition, the AR24027 includes several features, described below, to identify and overcome sources of interference. The AR24027 can be commanded to perform a spectrum analysis of the ISM band and report the results in either a graphical or tabular form. The command: >spectrum-analysis input=a-antenna dwell=xx...

    10 dBm per MHz maximum EIRP. Of these two limits the power density is the most restrictive for this radio. The installer must reduce the output power of the AR24027 so that the EIRP of the radio does not exceed 10 dBm. The antenna gain, cable and connector losses must be taken into account when computing the maximum output power.

  • Page 35: Upgrading The Firmware

    3.3.1 Description The operational firmware for the AR24027 is stored in Flash PROM and can be easily updated. The Flash PROM can hold multiple versions of the firmware simultaneously.

  • Page 68: Gain

    For omnidirectional coverage from fixed locations, AFAR Communications Inc. provides collinear antennas. The collinear design achieves gain by increased focus in comparison with the dipole design. The standard collinear antenna used with the AR24027 provides 9 dBi gain, representing an eight-fold power and sensitivity increase.

  • Page 69: Site Selection

    In setting up the AR24027 system, either vertical or horizontal polarization can be used, as long as polarization is the same at both ends of each link. For any given pair of line-of-sight antennas, it is essential that they both have the same polarization.

  • Page 70: Radio Horizon (Maximum Line-Of-Sight Range)

    AR24027 Operator’s Manual 6.3.2 Radio Horizon (Maximum Line-of-Sight Range) In visual terms, the horizon is the point in the distance where an object drops out of sight because it is blocked by the earth’s curvature. If the observer or object is elevated, the visual horizon is extended, that is, the object can be seen at a greater distance before it drops out of view.

  • Page 71: Antenna Orientation

    Performance of the system can be seriously degraded by mis-aligned directional antennas. The AR24027 has a built in feature that allows the operator to use an audio signal to assist in aligning the antenna. Refer to chapter 5 on the use of this built-in antenna alignment feature.

  • Page 72: Cable Loss (Attenuation)

    6.3.4 Cable Loss (Attenuation) The AR24027 is housed in a watertight enclosure so that it may be mounted in very close proximity to the antenna. Using short cables to connect the radio to the antenna reduces signal losses. Table 3.2 shows loss per 100 feet (30 meters) at 2.4 GHz for typical antenna cable types.
