  • Page 5: Section 1 Introduction

    Technical Support for access to the Professional Installation Guide. The M900S system consists of two types of radios: Access Points (APs) and Subscriber Units (SUs). Up to 126 subscriber units can be supported by a single AP, which acts as a hub in a star configuration. 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: Smartpolling™ & Bandwidth Throttling

    SmartPolling™ & Bandwidth Throttling One of the major advantages of the M900S system is the ability of the AP to handle multiple SU connections and share the 3 Mbps data throughput efficiently. Bandwidth allocation is managed by the AP’s SMARTPolling algorithm according to provisioning rules set up by the system administrator.

    Figure 3: Bottom of Radio At the bottom of the M900S are two access ports: a twist-on weatherproof cable port for RJ-45 Ethernet (and PoE), and a translucent access cover plug over the unit’s diagnostic LEDs and reset button. The LEDs will be discussed later in this text.

    Evaluate Link Quality The M900S uses the concept of “association” to indicate that the APs and SUs are communicating. If all parameters are properly set, the AP will begin actively searching for the SUs in its SUDB. Once an active SU is detected, the authentication and association process will begin.
