Wireless Optical Communication

Overview

Taara uses Wireless Optical Communication (WOC), a line-of-sight technology, to transmit video, voice and data at high speeds of up to 20 Gbps. A single link can cover distances up to 20 km. The effective range may be increased by relaying links. Taara's wireless links can be used to provide fiber backhaul, rapidly extend existing architecture, and create local area networks. Key advantages include:

  1. 1

    Quick deployment

    • Can be installed and uninstalled in less than a day
    • Easy to transport and requires limited support equipment
    • May be mounted on poles, towers, or rooftops
  2. 2

    Connectivity across difficult terrain

    • Sites located around water bodies
    • Forested region
    • Railway tracks and dense urban areas
  3. 3

    No right of way permits

    • No right of way permits or spectrum license
    • Data is transmitted wirelessly with Class 1M eye-safe lasers in the unlicensed infrared band ( 193 THz)
  4. 4

    Cost competitive & easy to integrate

    • Significantly favorable economics on a cost per GB/km compared to traditional alternatives
    • Based on open standards to work with existing infrastructure
