  • Page 3: Scope

    This User guide is the primary document for installation and operation of the System. It provides basic information and product background for system integrators and designers evaluating one or more of MeshLinx’s technologies related to the MWI-5000 Spatial Division Multiple Access (SDMA).

  • Page 4: Guide Content

    • Glossary of important terms 2.0 Introduction The MWI-5000 System is designed to help in the testing and evaluation of the MeshLinx MWI-5000, a tri-channel IEEE 802.11 MAC/Base Band processor. The system is a complete operating three channel Access Point that can be configured as a three sector SDMA AP or a dual-band (2.4 and 5GHz) AP with a monitoring...

    3.1.2 User Distribution As a general rule, it is a good idea to locate the MWI-5000 System in the center of the distribution of users, but this assumes a fairly even distribution. Because configuration (and reconfiguration) of the sectors is so simple, and MeshLinx’s...

  • Page 6: Obstacles

    The ideal location must also provide for power and network connections for the MWI-5000 System. Because it is 802.3af compliant, a single Power over Ethernet cable will provide both. If PoE hubs are not in use, the MWI-5000 System must be located where a source of AC power is available.

  • Page 7: Power-Over-Ethernet Connection

    3.2.3 Using the External Power Supply If you are not using powered Ethernet, the MWI-5000 System is powered by the included external power supply. Plug the external supply into an AC source (100– 250V, 50–60Hz) and plug the DC side into the MWI-5000 System External Power Supply connector.

    This section explains the Command Line Interface (CLI) used with the MWI-5000 System. Note: Although the CLI can be used to change settings while the MWI-5000 System is running, we recommend that it be stopped before making changes and restarted once the changes have been made. Changes do not take affect until the system is restarted.

  • Page 84: Mode

    The MWI-5000 will automatically monitor for known radar signatures when Spectrum Management is enabled (see discussion of this parameter below). If radar signatures are detected, the MWI-5000 will switch to a radar-free channel. The process of switching channels may disrupt the quality of time-sensitive services like voice. Since radar avoidance is required by law (see the 802.11h standard and associated FCC and ETSI...

  • Page 85: Channel

    If the Listen + Learn feature is enabled, the process of channel selection is continuous and fully automatic. The MWI-5000 monitors for interference in all channels and either stays on the current channel or switches channels if overall performance would benefit from the switch.

  • Page 86: Transmit Power

    It is recommended that this parameter be set to Max54 and not modified by the user, as doing so guarantees the MWI-5000 will never transmit a distorted frame due to an excessive transmit power level (optimizes range and throughput together).

  • Page 87: Sensitivity

    The sensitivity parameter is set to “high” by default, to ensure that distant stations are “heard” by the MWI-5000. If it is known that all stations needing network access through the MWI-5000 are relatively close the receive sensitivity can be set to “medium” or “low”.

    MeshLinx MWI-5000 User Guide 7.1.10 Diversity Diversity controls the use of antennas on the MWI-5000. Each wireless interface has a primary antenna (Antenna 1, default) and a secondary antenna (Antenna 2). Either of these antennas can be selected manually for an interface. The setting applies to both receive and transmit operations.

    7.1.14 RTS/CTS The RTS/CTS parameter determines whether or not the MWI-5000 MAC will initiate an RTS/CTS sequence preceding transmission of certain data frames, as indicated by the RTS/CTS Threshold parameter. Typically, RTS/CTS exchanges are done to ensure the medium is clear prior to transmitting data.
