UTStarcom is a astronomy 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 UTStarcom rather than just read about it. In short: UTStarcom Holdings Corp. (UT斯达康) is a Chinese global telecom infrastructure provider headquartered in Beijing.

Key takeaways

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

Reference excerpt

UTStarcom Holdings Corp. (UT斯达康) is a Chinese global telecom infrastructure provider headquartered in Beijing. The company develops and supplies a broad range of telecommunication devices to communications service providers and network operators including fixed and mobile network operators, as well as to enterprises. Traditionally, the company had focused on markets in China, Japan, and India, but has expanded to markets in Africa, Central and Latin America, and the Middle East. The company's products are designed to work with existing telecommunications infrastructure to provide low-cost voice and data services for access to both wireless (Wi-Fi) and fixed line products, optimized for mobile backhaul, metro aggregation, broadband access and Wi-Fi data. As of 2015, the company focuses on two core areas: broadband and next-generation network (NGN). The company has offices worldwide with business and R&D centers located in China, Japan, South Korea, India, the Middle East and Europe. It is listed on the NASDAQ since 2000.

History The company was founded in 1995 as a merger between Unitech and Starcom Networks to form UTStarcom. Unitech was founded in 1991 by Hong Liang Lu (陆弘亮), a Chinese entrepreneur with a BS degree from UC Berkeley, as Unitech Telecom. It was focused on the telecommunications markets in China, Japan, United States and India, with its initial presence in China established in 1993 in Hangzhou, Zhejiang. Starcom Networks was founded in 1991 by Ying Wu (吴鹰) and a team who had worked together at the Bell Labs in New Jersey, United States. After several years of trying to expand its business globally, UTStarcom launched the Personal Handy-phone System, also known as the Personal Access System, a technology originally developed in Japan. In March 2000, UTStarcom went public on the NASDAQ. In July 2008, UTStarcom sold its Personal Communications Division to AIG.

Worked examples

Example 1 — a first encounter with UTStarcom

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

In research: UTStarcom appears in astronomy 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 UTStarcom 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: UTStarcom is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1991 establishments in China, 1991 in Beijing, Chinese brands, so understanding it makes those chapters shorter.
In everyday life: Look for UTStarcom 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.
