Wireless Networks Bridge Past and Present in S. Korea’s River Restoration Project

Even though we are headquartered in the US, our most innovative and creative projects seem to happen in Asia Pacific first, and specifically in Korea. The latest example of this trend is the “4 Rivers” restoration project, which takes advantage of Firetide’s extensive product line – mesh, access points and customer premises equipment. The network is also multi-service, supporting a variety of applications: from public safety and emergency preparedness to free public Wi-Fi.

Billion dollar river restoration project

The South Korean government is undertaking a two billion dollar restoration project of the country’s four major rivers – the Han River, the Yeongsan River, the Nakdong River and the Seomjin River – and surrounding recreational areas. When completed in 2012, the multi-service wireless infrastructure will provide a sensor network for water level, temperature and pollution measurement; a video surveillance network to monitor the dams; and public Wi-Fi service for adjacent riverside parks.  Funded by the government, the project’s main objective is to prevent disasters caused by flooding, while supporting environmental preservation and attracting more visitors to the area.

240 miles of rivers to be covered

The four major rivers are over 240 miles in length combined. To cover this area, more than 200 Firetide MIMO and non-MIMO mesh nodes along with 300 cameras from Sony, Axis Communications and Samsung will be deployed to support the sensor and video surveillance applications. In addition, free public Wi-Fi service will be provided in adjacent parks using Firetide’s 802.11n wireless access points and customer premise equipment (CPEs).

Unique wireless mesh design

This projects illustrates the convergence of voice, video and data services over a wireless network – deployed in areas previously thought impossible or impractical to connect. The diagram below shows a section of the network, deployed in a redundant linear loop topology. Where the bends of the river allow, additional redundant links are built in to connect nodes within the chain. The section depicts about 10 km of a river “as the crow flies.”

Backbone for ‘u-Korea’ projects

The wireless mesh technology being used in the ‘4 Rivers’ project has also been deployed in other South Korean wireless projects such mobile video surveillance at Seoul Subway, “children safety zones” in Seoul, and parks,  beaches and other recreational areas is Korea’s largest cities. We can even say that Firetide is the de facto wireless mesh standard for the backbone of South Korea’s ‘u-City’ government-supported programs to bring ubiquitous digital services to residents, tourists, employees and businesses throughout the country.

Jan 26 Seminar: Designing and Specifying High-performance Wireless Infrastructure

Filed under: Physical Security,Technology,Wireless backhaul,Wireless Mesh,WLAN — kseniacoffman @ 9:20 am

If you are our neighbors in the San Francisco Bay Area, or willing to drive/fly, join us for an upcoming seminar organized by Firetide in Pleasanton, California on January 26.

Specifying and Designing High-Performance Wireless Infrastructure
Wednesday January 26, 9:00 AM – 4:45 PM

Why is wireless infrastructure essential?

Wireless is gaining acceptance as a reliable transport and an alternative to cable and fiber in municipal video surveillance, transportation, government, education and industrial installations. Did you know that deploying wireless instead of fiber can save up to 90% of network infrastructure costs? This translates to projects moving forward, rather than being bogged down in funding discussions.

Who should attend?

If you are researching, planning or specifying a wireless infrastructure projects – don’t miss this event. The seminar is designed for security and IT network integrators, A&E and infrastructure consultants, public safety technology leaders, security directors, network and IT managers tasked with managing wireless infrastructure initiatives, or extending reach of security and IT networks to areas where wired infrastructure does not exist.

What information will you receive?

This full day seminar will provide essential information about wireless technology options and design considerations for high-performance wireless infrastructure for real-time video surveillance, voice and data applications:

  • Design considerations for wireless IP networking
  • Wireless technology options, and how to pick the right one for the project
  • Mistakes to avoid during specification and design

What topics will be covered?

  • Designing for High-performance Wireless; Wireless Trends
  • RF Basics for Successful Project Design
  • Wireless applications; Mesh and mobility
  • Wireless Infrastructure: Project Fit and Key Differentiators
  • Specification & Design: Approaches; Tools; Best Practices

What past attendees have been saying?

“Enjoyed interaction and two-way communications. It was not just a lecture, but back-and-forth.”

“Good mix of content, technical vs. applications.”

“All of the presenters were very knowledgeable, and were able to answer our questions effectively.”

Sounds interesting?

The seminar will be focused on wireless for government, commercial and transportation applications (i.e. we will not be covering in-home, consumer-grade Wi-Fi) and will use Firetide’s technology and deployments as examples. If you have an interest in industrial-grade wireless technology, mesh networking or Firetide, you will benefit from this event. This seminar is approved for BICSI Continuing Education Credits (CEC); you will receive 4 to 6 CECs (details on BICSI web site).

If you are interested in this event, please send an email to Ksenia Coffman (kcoffman-at-firetide-dot-com).

Cannot make it to Pleasanton? We will host this seminar in other locations throughout the United States in 2011. Stay tuned!
