IBM has tested the mesh network to restore communication after a disaster

IBM has tested a system to quickly deploy a network for data transmission in areas with damaged infrastructure after natural disasters. It consists of a waterproof Autonomous devices that form a mesh network that allows users to connect to the Internet via Wi-Fi, reported in the IBM blog.

Often when natural disasters destroyed critical infrastructure, including telecommunications, making it difficult for rescuers to gather information on the status of people and infrastructure. For example, in 2017, Puerto Rico was hit by hurricane Maria, which almost the entire island was left without electricity and communication. For fast partial recovery when the American company proposed to use different approaches. AT&T has launched a Telecom drone, and company X, part ofn Alphabet, unfurled over the island a network of telecommunication of the stratosphere.

Engineers from IBM proposed to use for such situations another approach is to deploy a large network for data transfer without significant cost. Under the project OWL, they have developed a network consisting of individual small devices that can be placed on trees, road signs and even on the water due to the waterproof casing. They can be placed not only manually, but also, for example, dropping from drones or helicopters. Each device has its own battery and is able to work autonomously.

The network proposed by IBM, consists of three device levels. Device type DuckLink responsible for liaising with end users via Wi-Fi. Once connected, the user is taken to a page similar to the login page in the public networks. In it, he can send the rescue message and the images of destruction, as well as to access the area map with plotted points of assistance. The data received from the users fall into a single tracking system, which was also developed by the project participants.
