LiteBeam®
5 GHz, 23 dBi airMAX® CPE with InnerFeed Technology
Models: LBE-M5-23, LBE-5AC-23
Introduction
The LiteBeam® is the latest evolution of a lightweight and compact, outdoor wireless broadband product from Ubiquiti Networks. Each of these models was designed to be an affordable cost/performance solution for long-distance, wireless broadband bridging. It operates in the worldwide, license-free 5 GHz frequency range with high-performance speeds.
The LiteBeam combines proprietary hardware and software technologies to deliver its breakthrough combination of throughput and range with cost-effective value.
The InnerFeed® technology integrates the entire radio system into the antenna feed, and our revolutionary airMAX TDMA protocol enhances network performance and scalability.
Integrated airMAX® Technology
Unlike standard Wi-Fi protocol, the exclusive Ubiquiti Networks® airMAX Time Division Multiple Access (TDMA) protocol allows each client to send and receive data using pre-designated time slots managed by an intelligent AP controller. This "time slot" method eliminates hidden node collisions and maximizes airtime efficiency.
Compared to other systems in its class, the LiteBeam products deliver superior performance in reduced latency, throughput, and scalability.
- Intelligent QoS: Priority is given to voice/video for seamless access.
- Scalability: High capacity and scalability.
- Long Distance: Capable of high-speed, 30+ km links.
Application Examples
In a cost-effective WISP deployment, the LiteBeam acts as a CPE in an airMAX Point-to-Multipoint network.
A LiteBeam on each side of a Point-to-Point link.
Up to 100 airMAX stations can be connected to an airMAX Sector; four airMAX stations are shown to illustrate the general concept.
Hardware Overview
Full Adjustment Flexibility
The LiteBeam features a unique ball joint mount that provides adjustment flexibility along three axes for versatile mounting options. The mounting system, coupled with the built-in bubble level, enables quick and easy alignment.
Quick, Snap-and-Lock Assembly
The all-new mechanical design makes assembling the LiteBeam – literally – a snap. No tools are required. Simply snap the feed, antenna panels, rear housing, and ball joint mount together for a secure, solid assembly.
