Vislink Technologies

Vislink Technologies is a 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 Vislink Technologies rather than just read about it. In short: Vislink Technologies, Inc. is an American technology company that specializes in the collection, delivery, management and distribution of high quality live video and data. Founded as xG Technology in Sarasota, Florida in 2002, the company had acquired both Vislink and Integrated Microwave Technologies by 2017.

Key takeaways

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

Reference excerpt

Vislink Technologies, Inc. is an American technology company that specializes in the collection, delivery, management and distribution of high quality live video and data. Founded as xG Technology in Sarasota, Florida in 2002, the company had acquired both Vislink and Integrated Microwave Technologies by 2017. In February 2019, xG Technology formally changed its name to Vislink Technologies. The company is headquartered in Hackettstown, New Jersey and has regional offices in Billerica, Massachusetts and Anaheim, California, as well as global offices in the United Kingdom, Dubai and Singapore. Vislink is a publicly traded company listed on the NASDAQ Capital Market. Vislink has created a portfolio of intellectual property that includes cognitive radio, interference mitigation and self-organizing wireless network technologies for mobile services using licensed or unlicensed radio spectrum. In November 2020, Vislink was named a Deloitte Technology Fast 500 winner, and was among the fastest-growing North American technology companies. In February 2021, the company announced its "Connected Edge" strategy and began a pivot towards edge computing aimed at further expansion into sporting events, military contracts, satellite communications and first responder networks.

XMax xMax developed by xG Technology, Inc. is a cognitive radio based mobile VoIP and computer networking system operating in the license-free ISM 900 MHz band (902–928 MHz). xMax is built upon an end-to-end Internet Protocol (IP) system infrastructure that includes a line of base stations, mobile switching centers (MSC), handsets and modems. xMax currently operates in the unlicensed 900 MHz ISM band, although it has been designed to be programmed for operation in any licensed or unlicensed frequency from approximately 300 MHz to 3 GHz. The xMax system is designed to allow mobile operators to utilize free, unlicensed 902–928 MHz spectrum, which is available in most of the Americas. Unlicensed spectrum is an affordable alternative to licensed spectrum – such as what broadcasters use to transmit their signals. Any company or consumer can use unlicensed spectrum simply by following well-known rules.

Performance claims A press report was published in 2005 quoting inventor Joseph Bobier. The technology was said to compete with WiMax, but details were initially not disclosed. By 2006, the company announced it had "completed" the technology after six years of development. In 2009, a blogger wrote that he witnessed a xMax mobile VoIP pilot network operated by the company in Fort Lauderdale: "xMax worked well and is real. When you realize that this company may have found a way to take a frequency riddled with wireless garbage and turn it into a fully functioning wireless voice and data network you start to see how much of a game changer this could be for the wireless industry."

Antenna: commercially off the shelf antenna Range: typically 2–5 miles depending upon tower height and terrain. Data rate: 18 Mbit/s per basestation Spectrum used: Unlicensed 902–928 MHz band Interference: Ability to accept interference found on 902–928 MHz band Power: Less than 1 W From 2007 through 2009, Phil Karn published some analysis of the technology claims.

Worked examples

Example 1 — a first encounter with Vislink Technologies

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

In research: Vislink Technologies appears in 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 Vislink Technologies 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: Vislink Technologies is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2002 establishments in Florida, 2017 mergers and acquisitions, Broadband, so understanding it makes those chapters shorter.
In everyday life: Look for Vislink Technologies 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.
