Section 2 Introduction
Your Trango Broadband Access5830 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 Access5830 system.
Overview
The dual-band Access5830 is a highly versatile and cost effective outdoor point-to-multipoint solution for wireless
broadband service providers and enterprise connectivity applications. The Access5830 delivers 10 Mbps over the
air, and operates in the 5.8 GHz ISM band
The Access5830 system is classified as a Layer 2 multi-point bridge. Authentication of the SUs is performed using
a secure, proprietary method at the MAC level, and thus all forms of Ethernet traffic and unlimited IP addresses
will pass seamlessly over the system. There is no limitation on the number of IP addresses or hardware devices that an
individual SU may have physically connected to it.
Both APs and SUs can be easily configured and managed through built in serial and Ethernet interfaces. A web
browser can be used for quick set up and deployment. The Access5830 radios are powered using "power-over-
Ethernet" for ease and low-cost installation. Both APs and SUs feature a handy "site survey" tool to check for
interference.
The Access5830 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 512 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™. 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).
Figure 2-1: Typical Point-to-Multipoint Deployment
The Access5830 AP provides a host of comprehensive tools and functions. The AP typically resides at the center of the
point-to-multipoint (PMP) network, and performs all management functions including the allocation of bandwidth for all
associated SUs.
