Joel S. Engel

Joel S. Engel is a engineering 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 Joel S. Engel rather than just read about it. In short: Joel Stanley Engel (born February 4, 1936) is an American electrical engineer who made fundamental contributions to the development of cellular networks. Born in New York City, he obtained a B.Sc. in engineering at City College of New York (1957).

Key takeaways

Joel S. Engel belongs to engineering; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Joel S. Engel to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Joel S. Engel from memory before moving on to harder problems.

Reference excerpt

Joel Stanley Engel (born February 4, 1936) is an American electrical engineer who made fundamental contributions to the development of cellular networks. Born in New York City, he obtained a B.Sc. in engineering at City College of New York (1957). While working at the Massachusetts Institute of Technology in the research staff at Draper Laboratory on inertial guidance and stabilization systems, he also obtained an M.Sc. in electrical engineering (1959). He then moved to New Jersey and worked for Bell Labs most of his active research career (1959–83), and also earned a Ph.D. from Polytechnic Institute of Brooklyn on a thesis on data transmission over telephone lines (1964). He then worked at Bellcomm on guidance systems for the Apollo Program (1965) and at Page Communications Engineers in Washington, D.C. (1965–67) before returning to Bell Labs where he joined the mobile phone system research group. He also lectured at Polytechnic Institute of Brooklyn. After the Federal Communications Commission (FCC) opened up new frequencies (1968), his engineering team developed the architecture for cellular network and its parametrization (1971), which was the basis for Advanced Mobile Phone System, eventually commercialized (1983). After a rotation at AT&T (1973–75), Engel returned to Bell Labs as a Department Head with responsibilities for a broad range of projects. Engel later joined Satellite Business Systems (1983–86) as VP of engineering, and became VP of research and development at MCI Communications (1986–87), when MCI acquired SBS. He was VP of technology and Chief Technology Officer at Ameritech (1987–97). Engel was elected a member of the National Academy of Engineering in 1996 for contributions to the theory and design of cellular telecommunications systems.

Worked examples

Example 1 — a first encounter with Joel S. Engel

Start with the simplest possible case. Write down what Joel S. Engel claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, 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 Joel S. Engel 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 Joel S. Engel 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 Joel S. Engel

In research: Joel S. Engel appears in engineering 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 Joel S. Engel 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: Joel S. Engel is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1936 births, American chief technology officers, American electrical engineers, so understanding it makes those chapters shorter.
In everyday life: Look for Joel S. Engel 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.
