THE SHIFT TO DIGITAL, why NASCAR choose Motorola

NASCAR officials have enthusiastically embraced MOTOTRBO, and they applaud the benefits it has brought to the NASCAR experience. Smooth Management of Communications Traffic MOTOTRBO “does a super job for us,” according to Kerry Tharp, Director of Communications, NASCAR. “You have to communicate pre-race, during the race, and most importantly for us, post-race because when the race is over, that’s when our media operation kicks in for us full-bore. We bring in our top three drivers for interviews; we bring in our winning driver to the victory lane, and we also check in on the garage to make sure that post-race is going along as it should. We have to make sure we’re communicating quickly and concisely. Through MOTOTRBO, we’re able to do our jobs a whole lot better than we have in the past.” Read more ›

Bone conducting comminications, how this trumps every other type of earpiece

Music is a huge part of daily life but it has been for nearly as long as Human beings have been on this planet. I often point to a discovery of the 40,000-year-old flute dating back to the ice age as evidence for this, but in fact, all the evidence you need is all around you, every day. We bear in mind ballads and songs long after the folks who first composed them have died and rotted away (a plan which I find curiously soothing) and the music industry, love it or hate it, is definitely a big business.

Does the Walkie talkie tower actually appear like 2 way radio, and what else does it hold?

I’m happy you asked. 20 Fenchurch Street, affectionately named as the ‘Walkie Talkie Tower’ and maybe less affectionately identified as the ‘Walkie Scorchie’ (yeah, that’s a reputation that’s in no way catching on), is a commercial skyscraper in inner London. It’s presently under development and isn’t expected to be finished until next year. When all is said and done, it will eventually have cost some £200 Million to build.

Innovative or Simply Post-Modern? New Paradigms in the Study of “Radio”

Radio is the wireless transmission of signals through free space by electromagnetic radiation of a frequency significantly below that of visible light, in the radio frequency range, from about 30 kHz to 300 GHz. These waves are called radio waves. Electromagnetic radiation travels by means of oscillating electromagnetic fields that pass through the air and the vacuum of space.
Information, such as sound, is carried by systematically changing some property of the radiated waves, such as their amplitude, frequency, phase, or pulse width. When radio waves strike an electrical conductor, the oscillating fields induce an alternating current in the conductor. The information in the waves can be extracted and transformed back into its original form.
The etymology of “radio” or “radiotelegraphy” reveals that it was called “wireless telegraphy”, which was shortened to “wireless” in Britain. The prefix radio- in the sense of wireless transmission, was first recorded in the word radioconductor, a description provided by the French physicist Édouard Branly in 1897. It is based on the verb to radiate .
The word “radio” also appears in a 1907 article by Lee De Forest. It was adopted by the United States Navy in 1912, to distinguish radio from several other wireless communication technologies, such as the photophone. The term became common by the time of the first commercial broadcasts in the United States in the 1920s. The term was adopted by other languages in Europe and Asia. British Commonwealth countries continued to commonly use the term “wireless” until the mid-20th century, though the magazine of the BBC in the UK has been called Radio Times ever since it was first published in the early 1920s.
In recent years the more general term “wireless” has gained renewed popularity through the rapid growth of short-range computer networking, e.g., Wireless Local Area Network, Wi-Fi, and Bluetooth, as well as mobile telephony, e.g., GSM and UMTS. Today, the term “radio” specifies the actual type of transceiver device or chip, whereas “wireless” refers to the lack of physical connections; one talks about radio transceivers, but another talks about wireless devices and wireless sensor networks.
Radio systems used for communications will have the following elements. With more than 100 years of development, each process is implemented by a wide range of methods, specialized for different communications purposes.
Transmitter and modulation
Each system contains a transmitter. This consists of a source of electrical energy, producing alternating current of a desired frequency of oscillation. The transmitter contains a system to modulate some property of the energy produced to impress a signal on it. This modulation might be as simple as turning the energy on and off, or altering more subtle properties such as amplitude, frequency, phase, or combinations of these properties. The transmitter sends the modulated electrical energy to a tuned resonant antenna; this structure converts the rapidly changing alternating current into an electromagnetic wave that can move through free space.
Amplitude modulation of a carrier wave works by varying the strength of the transmitted signal in proportion to the information being sent. For example, changes in the signal strength can be used to reflect the sounds to be reproduced by a speaker, or to specify the light intensity of television pixels. It
was the method used for the first audio radio transmissions, and remains in use today. “AM” is often used to refer to the mediumwave broadcast band .
Frequency modulation varies the frequency of the carrier. The instantaneous frequency of the carrier is directly proportional to the instantaneous value of the input signal. Digital data can be sent by shifting the carrier’s frequency among a set of discrete values, a technique known as frequency-shift keying.
FM is commonly used at VHF radio frequencies for high-fidelity broadcasts of music and speech . Normal TV sound is also broadcast using FM.
Angle modulation alters the instantaneous phase of the carrier wave to transmit a signal. It is another term for Phase modulation.

how to buy a laptop computer

There are a great many laptops on the market; it is a very crowded marketplace indeed. This is all very well and good for the techie types out there who live on a diet of stats, acronyms and data, but what about those of us who really haven’t a clue? (And believe me, I am firmly in this category) 

Well, I recently set out to try and buy myself a laptop so that I can write whilst travelling, have regular access to the Internet (without fiddling with the tiny keys on an overpriced phone) and generally update my operations beyond late 19th century age-of-steam standards. To this end, I have talked to a couple of my more ‘technically minded’ friends and compiled for you a list of three questions that all prospective laptop owners should ask, before you get into anything even remotely technical.  Read more ›

Truly Communication? The Modern Communication : A Normative Critique.

Communication is the activity of conveying information through the exchange of thoughts, messages, or information, as by speech, visuals, signals, writing, or behavior. It is the meaningful exchange of information between two or more living creatures.
One definition of communication is “any act by which one person gives to or receives from another person information about that person’s needs, desires, perceptions, knowledge, or affective states. Communication may be intentional or unintentional, may involve conventional or unconventional signals, may take linguistic or non-linguistic forms, and may occur through spoken or other modes.”
Communication requires a sender, a message, and a recipient, although the receiver doesn’t have to be present or aware of the sender’s intent to communicate at the time of communication; thus communication can occur across vast distances in time and space. Communication requires that the communicating parties share an area of communicative commonality. The communication process is complete once the receiver understands the sender’s message.
Communicating with others involves three primary steps:
Thought: First, information exists in the mind of the sender. This can be a concept, idea, information, or feelings.
Encoding: Next, a message is sent to a receiver in words or other symbols.
Decoding: Lastly, the receiver translates the words or symbols into a concept or information that a person can understand.
There are a variety of verbal and non-verbal forms of communication. These include body language, eye contact, sign language, haptic communication,and chronemics. Other examples are media content such as pictures, graphics, sound, and writing. The Convention on the Rights of Persons with Disabilities also defines the communication to include the display of text, Braille, tactile communication, large print, accessible multimedia, as well as written and plain language, human-reader, augmentative and alternative modes, means and formats of communication, including accessible information and communication technology. Feedback is a critical component of effective communication.
Verbal communication
Human spoken and pictorial languages can be described as a system of symbols and the grammars by which the symbols are manipulated. The word “language” also refers to common properties of languages. Language learning normally occurs most intensively during human childhood. Most of the thousands of human languages use patterns of sound or gesture for symbols which enable communication with others around them. Languages seem to share certain properties although many of these include exceptions. There is no defined line between a language and a dialect. Constructed languages such as Esperanto, programming languages, and various mathematical formalisms are not necessarily restricted to the properties shared by human languages. Communication is the flow or exchange of information within people or a group of people.
Nonverbal communication
Nonverbal communication describes the process of conveying meaning in the form of non-word messages. Some forms of non verbal communication include chronemics, haptics, gesture, body language or posture, facial expression and eye contact, object communication such as clothing, hairstyles, architecture, symbols, infographics, and tone of voice, as well as through an aggregate of the above. Speech also contains nonverbal elements known as paralanguage. These include voice lesson quality, emotion and speaking style as well as prosodic features such as rhythm, intonation and stress. Research has shown that up to 55% of human communication may occur through non verbal facial expressions, and a further 38% through paralanguage. Likewise, written texts include nonverbal elements such as handwriting style, spatial arrangement of words and the use of emoticons to convey emotional expressions in pictorial form.
Oral communication
Oral communication, while primarily referring to spoken verbal communication, can also employ visual aids and non-verbal elements to support the conveyance of meaning. Oral communication includes speeches, presentations, discussions, and aspects of interpersonal communication. As a type of face-to-face communication, body language and choice tonality play a significant role, and may have a greater impact upon the listener than informational content. This type of communication also garners immediate feedback.
Business communication
A business can flourish only when all objectives of the organization are achieved effectively. For efficiency in an organization, all the people of the organization must be able to convey their message properly.
Written communication and its historical development
Over time the forms of and ideas about communication have evolved through the continuing progression of technology. Advances include communications psychology and media psychology, an emerging field of study.
The progression of written communication can be divided into three “information communication revolutions”:
# Written communication first emerged through the use of pictographs. The pictograms were made in stone, hence written communication was not yet mobile.
# The next step occurred when writing began to appear on paper, papyrus, clay, wax, etc. with common alphabets. Communication became mobile.
# The final stage is characterized by the transfer of information through controlled waves of electromagnetic radiation and other electronic signals.
Communication is thus a process by which meaning is assigned and conveyed in an attempt to create shared understanding. This process, which requires a vast repertoire of skills in interpersonal processing, listening, observing, speaking, questioning, analyzing, gestures, and evaluating enables collaboration and cooperation.
Misunderstandings can be anticipated and solved through formulations, questions and answers, paraphrasing, examples, and stories of strategic talk. Written communication can be clarified by planning follow-up talks on critical written communication as part of the every-day way of doing business. A few minutes spent talking in the present will save valuable time later by avoiding misunderstandings in advance. A frequent method for this purpose is reiterating what one heard in one’s own words and asking the other person if that really was what was meant.
Effective communication
Effective communication occurs when a desired effect is the result of intentional or unintentional information sharing, which is interpreted between multiple entities and acted on in a desired way. This effect also ensures the messages are not distorted during the communication process. Effective communication should generate the desired effect and maintain the effect, with the potential to increase the effect of the message. Therefore, effective communication serves the purpose for which it was planned or designed. Possible purposes might be to elicit change, generate action, create understanding, inform or communicate a certain idea or point of view. When the desired effect is not achieved, factors such as barriers to communication are explored, with the intention being to discover how the communication has been ineffective.
Barriers to effective human communication
Barriers to effective communication can retard or distort the message and intention of the message being conveyed which may result in failure of the communication process or an effect that is undesirable. These include filtering, selective perception, information overload, emotions, language, silence, communication apprehension, gender differences and political correctness
This also includes a lack of expressing “knowledge-appropriate” communication, which occurs when a person uses ambiguous or complex legal words, medical jargon, or descriptions of a situation or environment that is not understood by the recipient. Read more ›

Say I’m in a high-speed car chase, what’s the best way to escape the police?

(Asked by Nick from Kent)

In my experience, the weapons cheat usually works a treat. I find that a roadblock is considerably less of an issue if you’re armed with a rocket launcher and twin uzis…

As for the real world, one wonders just why you’re asking me, Nick? (I really don’t want this article popping up as evidence at your trial while I go down for aiding an abetting you). Still, I must answer the questions my editor selects for me, so I’ll give this one a go (but don’t come crying to me if you end up serving several consecutive life sentences, OK?) Read more ›
