  • Page 5: Section 1 Introduction

    The M900S system consists of two types of radios: Access Points (AP) and Subscriber Units (SU). The AP unit acts as a hub in a star configuration wireless multipoint network supporting up to 126 subscriber units. The AP delivers wireless broadband service (Ethernet connectivity) to one or more SUs according to a proprietary adaptive dynamic polling algorithm called SMARTPolling™...
  • Page 6 Introduction Each of the above parameters are set in the AP by the system administrator and cannot be controlled at the SU. These parameters will be covered in greater detail later in this text. When power is first applied to a properly installed SU, it will scan all available channels, searching for an AP with matching Base ID and MAC in its SU Database.

    Switch Settings M900S firmware includes several “switches” which are used to set certain operational parameters of the radios. Switch settings can be changed via the HTTP browser interface or the Command Line Interface. For purposes of radio TCP/IP management, the following three switches are important: SU Switch 2 - TCP/IP access to SU from AP side of network requires that the SU’s switch 2 (SW 2 –...

    Getting Started AP and SU Switch 5 – In order to utilize the radio’s HTTP Browser interface, switch 5 (SW 5) must be “ON”. Default seting for SW 5 (from factory) is “ON”. SU Switch 6 - TCP/IP access direct to SU from SU side of network requires that switch 6 (SW 6) be “ON”. Default setting for SW 6 (from factory) is “ON”.

    Basic Configuration via Browser Interface RFRx Threshold: Sets the receive threshold of the radio. The radio will not process signals received below this level, so it is very useful for interference mitigation. For smaller radius of operation use a higher threshold (-65 is higher than -70). Broadcast Packet: This software switch (0) enables/disables the blocking of Ethernet control packet except ICMP and ARP to reduce the amount of unnecessary overhead introduced to the wireless link.
