GoTenna

GoTenna 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 GoTenna rather than just read about it. In short: goTenna (goTenna Inc.) is a technology company that creates mesh networking devices that pair with smartphones, allowing users to send texts and share locations on a peer-to-peer basis without needing active cell networks History The idea for goTenna came about after Hurricane Sandy knocked out 25 percent of cell towers, and caused outages for 25 percent of Internet services, across 10 states on the East Coast.

Key takeaways

GoTenna 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 GoTenna to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of GoTenna from memory before moving on to harder problems.

History

The idea for goTenna came about after Hurricane Sandy knocked out 25 percent of cell towers, and caused outages for 25 percent of Internet services, across 10 states on the East Coast. Officially incorporated in April 2013, In 2014, goTenna rolled out its first consumer product, the goTenna, a pocket-size communication tool that lets off-grid travelers talk to one another without cell service. In September 2016, goTenna launched goTenna Plus, a, subscription-based upgrade to the goTenna applications, which includes the capability to use other goTenna users as gateways to relay messages through to traditional SMS networks. The company also released its software development kit, enabling developers to create new applications using goTenna hardware. However, its license does not permit use with open source copyleft licenses. Around the same time, goTenna unveiled a second-generation device: goTenna Mesh, the first consumer-ready mesh network of its kind, available to 49 countries.

goTenna Pro In March 2017, the company announced its goTenna Pro line, for professional mobile radio communications needs, leaving the consumer market for government markets. To finance its pivot, the company raised $24M in Series C equity and debt funding in 2019

Worked examples

Example 1 — a first encounter with GoTenna

Start with the simplest possible case. Write down what GoTenna 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 GoTenna 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 GoTenna 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 GoTenna

In research: GoTenna 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 GoTenna 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: GoTenna is common in secondary-school and first-year university syllabi. It links to neighbouring topics Companies based in Brooklyn, Companies based in New York City, Networking hardware companies, so understanding it makes those chapters shorter.
In everyday life: Look for GoTenna 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.

Frequently asked questions

What is GoTenna in simple terms?

Why does GoTenna matter?

Because it connects several computer science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study GoTenna?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
