Red Hook Wi-Fi

Red Hook Wi-Fi is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Red Hook Wi-Fi rather than just read about it. In short: Red Hook Wi-Fi is a free-to-use, Wi-Fi mesh network that provides internet access to the Red Hook neighborhood of Brooklyn, New York. It is operated by the Red Hook Initiative.

Key takeaways

  • Red Hook Wi-Fi belongs to computer science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Red Hook Wi-Fi to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Red Hook Wi-Fi from memory before moving on to harder problems.

Reference excerpt

Red Hook Wi-Fi is a free-to-use, Wi-Fi mesh network that provides internet access to the Red Hook neighborhood of Brooklyn, New York. It is operated by the Red Hook Initiative.

Background

Due to the location of Red Hook, Brooklyn, between the Red Hook Channel and the Buttermilk Channel, many of its residents face various challenges in accessing broadband service. A survey found out that many people in the area accessed the internet primarily through mobile phones and that over 30% of the population did not have broadband access at home.

Beginning in Fall 2011, the Red Hook Initiative (RHI), a Brooklyn-based 501(c)(3) nonprofit organization, approached the Open Technology Institute about collaborating on a community wireless network. RHI wanted a way to communicate with the residents immediately around its community center. When the network was initially launched, it had support for up to 150 simultaneous users and ran on an open-software platform called Commotion.

Hurricane Sandy In 2012, after Hurricane Sandy struck the area, and many internet and communication systems were down throughout much of the city, Red Hook remained connected through its mesh network and the headquarters of the Red Hook Initiative became a hub for volunteer coordination, donation collections food distribution as residents came to the Red Hook Initiative's office to charge their devices and connect to the internet. Shortly afterwards, the Federal Emergency Management Agency (FEMA) connected Red Hook Wi-Fi to its satellite system, linking itself, the residents and the Red Cross into a communication matrix that could be used to find out about emergency relief, food banks as well as shelter locations. After the relief efforts had finished, a team led by the Red Hook Initiative continued to make improvements to the mesh network by installing nano stations powered by solar panels on rooftops around the Red Hook neighborhood. Though the Red Hook Wi-Fi project was already in the works before Hurricane Sandy struck, it gained additional media attention after the storm. In 2015, Red Hook Wi-Fi was selected to be part of the city's resiliency initiative from a group of 27 finalists competing in the Resiliency Innovations for a Stronger Economy.

Worked examples

Example 1 — a first encounter with Red Hook Wi-Fi

Start with the simplest possible case. Write down what Red Hook Wi-Fi claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Red Hook Wi-Fi before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Red Hook Wi-Fi ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Red Hook Wi-Fi

In research
Red Hook Wi-Fi appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Red Hook Wi-Fi in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Red Hook Wi-Fi is common in secondary-school and first-year university syllabi. It links to neighbouring topics Community networks, Mesh networking, Red Hook, Brooklyn, so understanding it makes those chapters shorter.
In everyday life
Look for Red Hook Wi-Fi outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
