Introduction

Section 1 Introduction

Your Trango Broadband M2400S radio system provides a reliable and robust means to deliver broadband access to a wide geographic region through wireless Ethernet connectivity. This section will familiarize you with basic operational concepts, as well as an overview of the various components and hardware of the M2400S system.

Overview

The M2400S is a highly versatile and cost effective outdoor point-to-multipoint solution for wireless broadband service providers’ enterprise connectivity applications. The M2400S delivers 5 Mbps over the air, and operates in the 2.4 GHz license free ISM band. Each radio includes an integrated dual polarized (horizontal and vertical) antenna, as well as a connector for the attachment of an external antenna, such as a Yagi or an omni style antenna.

Note: If you are going to install an external antenna, refer to the M2400S Professional Installation Guide. 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™. Network operators can co-locate multiple APs at a single cell site, thus increasing the aggregate throughput available at each wireless point-of-presence (POP).

The AP typically resides at the center of the point-to-multipoint (PMP) network. It performs all management functions, including the allocation of bandwidth for all associated SUs. The M2400S AP provides a host of comprehensive tools and functions.

The M2400S system is classified as a Layer 2 multi-point bridge, thus all forms of Ethernet traffic will pass seamlessly over the system. There is no limitation on the number of IP addresses or hardware devices to which an individual subscriber unit may be connected.

Authentication of Subscriber Units is performed using a secure proprietary method, which is based on the MAC address of the Subscriber Unit. In order to establish a wireless link the MAC address of the SU must be present in the Access Point’s Subscriber Unit Database (SUDB).

Both APs and SUs are IP addressable and can be managed remotely across the network. Users can manage the radios using the telnet command line interface or the graphical HTTP browser interface. The M2400S also provides remote firmware upgrade capability utilizing TFTP. APs include a full featured SNMP agent for the monitoring and controlling of both APs and SUs via SNMP.

The M2400S radios are powered using "power-over-Ethernet" for ease and low-cost installation. A single Cat-5 cable carries both Ethernet and DC power to the radio.
