  • Page 5: Section 1 Introduction

    Contact Technical Support for access to the Professional Installation Guide. The M2400S 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 M2400S system is the ability of the AP to handle multiple SU connections and share the 5 Mbps data throughput efficiently. Bandwidth allocation is managed by the AP’s SMARTPolling™...
  • Page 7: Section 2 Hardware Overview

    Section 2 Hardware Overview This section provides detail about each radio in the M2400S family. Each radio in the M2400S family includes a built-in, electronically switchable, dual-polarized antenna, as well as a reverse polarity SMA connector for the attachment of an external antenna. For ease of installation all units are designed for outdoor installation and powered by power-over-Ethernet (POE).

    Passwords In order to log into an M2400S radio (either through telnet or through the web browser interface), the user must know the IP address and password. Both AP’s and SU’s feature two levels of passwords: Read Write (RW) and Read Only (RO).

    Evaluate Link Quality The M2400S uses the concept of “association” to indicate that the AP and SU’s are communicating. If all parameters are properly set, the AP will begin actively searching for the SU’s in its SUDB. Once an active SU is detected, the authentication and association process will begin.

    Allow approximately 60 seconds for the radios to complete the boot-up cycle and to associate. If the AP is busy servicing many SUs, the association process may take slightly longer. Trango Broadband Wireless — User Manual M2400S Rev A Page...
  • Page 20: Link Control Page

    The radio’s firmware includes several useful tools to assist in determining which SUs are associated, and the quality of each link. One method for verifying link quality is by using the Link Control page. Trango Broadband Wireless — User Manual M2400S Rev A ASSOCIATION LED (GREEN) Blinking once every second in Opmode "OFF"...
