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.
