The binary data 510 identifying the locations of the ABS subframes 502a, and non-ABS subframes, can then be interpreted by a decoder 512 using index modulation to obtain output bits representing commands and/or data. RECEIVER:> The receiver is the destination of the message. If the 0th and 5th subframes are “don't care” subframes as they are in the LTE protocol, the subsequent twenty subframes using a combination of remaining five low energy subframes can represent a unique ID corresponding to 15,504 different devices. Please permit … 8 illustrates a code detection and correction mechanism, according to an example embodiment. This approach works with any number of ABS settings chosen by the LTE eNB, and accordingly adjusts the encoding of control messages at maximum possible transmission rates. In order to find these reference points, in some embodiments, the receiver finds dominant peaks across the moving average output. 3 is a circuit schematic for an Internet of Things (IoT) energy sensor used to detect an energy pattern of a wireless signal, such as an LTE signal, according to an example embodiment. FIG. It can be observed that the SER is much higher for the sensors located in an added test conducted in a stadium environment, which is due to the presence of a high number of sensors at locations with low input power around the stadium areas, such as parking lots. The example diode-based voltage rectifier 303 removes the carrier frequency from the received LTE signal and converts the incident power into electrical current. 1. The entire teachings of the above application are incorporated herein by reference. Hence, it is nothing but digital modulation. It consists in changing the information into some form of logical and coded message. While example embodiments have been particularly shown and described, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the scope of the embodiments encompassed by the appended claims. Chunking and mnemonics (discussed below) aid in semantic encoding; sometimes, deep processing and optimal retrieval occurs. “SYNC” may refer to a SYNC reserve control signal in session-oriented communication management to synchronize IoT devices. In the word \"bat,\" for example, “b” is the start of the syllable and the letters “at” form the end of the syllable. The encoding/decoding model of communication was proposed by Stuart Hall in 1973. On the other hand, in oral communication, decoding includes listening and understanding. FIG. An XOR operation is performed on ‘0001’ and ‘1111’, and then the resultant XORed data ‘1110’, 802c, is encoded using index modulation by placing low energy subframes at locations 3 and 6 of the third frame 801c. Encoding can be a very effective form of integrated marketing communication when it is executed well. Circuit 300 may create the output current and perform energy harvesting using a RF energy harvester circuit that is designed to operate in the LTE frequency band of 700 MHz with high sensitivity to the changing signal patterns within the LTE subframes. There are many forms of encoding to choose from including verbal, graphic, musical, and animation. Fortunately in most mobile communication system, somebody else has already determined the answer to these questions. 3 while detecting energy of a signal transmitted by an RF source in alternate 1-millisecond periods using ON-OFF keying (OOK) modulation. As the range increased, the throughput gradually decreased. Other types of codes include BinHex, Uuencode (UNIX to UNIX encoding) and Multipurpose Internet Mail Extensions (MIME). Alternatively, circuit 300 may not include analog-to-digital converter 304 and micro-controller 305, and instead use passive gate logic to convert the output current to binary data that represent commands. FIG. 1. It designates each quantized level by a binary code. Rob Toulson, Tim Wilmshurst, in Fast and Effective Embedded Systems Design (Second Edition), 2017. Noise. With error correction, this range extended to 21 feet. 62/577,509, filed on Oct. 26, 2017. For example, in LTE or WCDMA system.. 3GPP specification specifies all the details of Encoding/Decoding process and you don't have to worry about these questions. This method of piggybacking overlaid signal 102c onto an existing signal 102a is not limited to LTE protocols. Encoding can be a very beneficial form of marketing when time and thought are put into it. A.C. Problems Associated with Decoding Decoding is often difficult to achieve because factors such as education, opinions, and emotional states shape how a receiver interprets a message. Upward communication c. Diagonal communication d. Horizontal communication 22. One of the first things that the sender must determine is the channel that s/he will use to convey the message.For our purposes as public speakers, the channel is the spoken word sent through the sound waves of the human voice. The decision threshold may be set to half of the peak amplitude, whereas the peaks give the best sample instances (decision instances) for the decision. 10A and 10B are graphs illustrating Symbol Error Rate (SER) over a range of distances for a set of outdoor receiver scenario experiments and for indoor receiver scenario experiments. Down ward communication and Upward communication are : a. Vertical communication b. Horizontal communication c. Diagonal communication d. None of these 23. Furthermore, the cost of building and maintaining an IoT control infrastructure can be prohibitive. Circuit 300 must have high enough sensitivity and fast enough responsiveness to detect the alteration of energy levels that occurs during the transmission of a frame in existing protocols such as LTE. It can be observed that for the given experimental set up, IoT achieves maximum throughput for communication ranges up to 9 feet. This can be accomplished with any signal that is governed by a protocol that defines a frame that contains subframes of varying energy level. However, to update the threshold value periodically, the peak detection function may be enabled after an interval of a set number of subframes. Selecting the right language is essential for effective encoding. 2. Feedback can also be formally documented and communicated as part of business processes such as performance management.The following are illustrative examples of feedback. Two sensor deployments were studied, both indoor and outdoor, with the BS fixed at the outdoor location. 1, frame 501 can be part of signal 102a transmitted by station 101 and is governed by an existing communications protocol, such as LTE. The term requires an element of success in transmitting or imparting a message, whether information, ideas, or emotions.A communication therefore has three parts: the sender, the message, and the recipient.The sender ‘encodes’ the message, usually in a mixture of words and non-verbal communication. Richard Nordquist. The ⦠For example, you might smile to reinforce your message's happy tone. In some embodiments, the first frame 601a is allocated four ABS to be able to represent the different types of R-preamble. Encoding can have two meanings: In computer technology, encoding is the process of applying a specific code, such as letters, symbols and numbers, to data for conversion into an equivalent cipher. This example embodiment may additionally include dynamically adjusting to the number of ABSs chosen by the eNB seamlessly through automatic rate adaptation methodology and a session management protocol to maintain contextual information and handle possible interruptions caused by complete absence of ABS or any change of ABS settings. In this case, the experiments achieved less than 6% SER up to a range of 15 feet. Decoding is step two of a process first described by communication scholar Stuart Hall. If the ID is not a match, the device will wait for the next SYNC command. This is known as phonological awareness. The Ethernet communication protocol is evaluated, introducing the Manchester encoding method.Local and wide area networks are discussed and a number of Internet protocol concepts are introduced, particularly the use of IP addresses for configuring and sharing data over a network. Therefore, the peak detection function can be disabled for a period of time, once the dominant peak is found. Furthermore, circuit 300 must be sensitive enough to register the difference between a “high” energy subframe representing a ‘0’, for example, containing cell data and a “low” energy subframe such as an ABS representing a ‘1’, for example. Session management allows for the targeting of a single device in a wide-spread network of IoT devices when overlaying signal 102c on a city-wide scale transmission 102a. For example, many URI schemes and protocols based on RFCs 1738 and 2396 presume that the data characters will be converted to bytes according to some unspecified character encoding before being represented in a URI by unreserved characters or percent-encoded bytes. A communication medium is a means of conveying meaning to people. After generating an idea, the sender encodes it in a way that can be comprehended by the receiver. Windows Communication Foundation (WCF) includes three types of encoding for SOAP messages: Text, Binary and Message … âEncodingâ can be defined as transforming an abstract idea into a communicable message. FIG. The average subframe energy levels can be detected in time relative to a synchronization indicator associated with a frame or respective synchronization indicators associated with the frame and a successive frame, and the pattern of energy levels can be defined by a time sequence of average energy levels relative in time to a synchronization indicator associated with the frame or respective synchronization indicators associated with the frame and a successive frame. In one embodiment, passive electrical elements compose the decoder. It converts encoded data communication transmissions and files to their original states. The session management protocol can allow encoding of information across a span of multiple frames (e.g., sequential frames or every other frame), or when the existing protocol operator temporarily reduces the number of low energy subframes. The sensor-BS separation distance was increased from 2 feet to 70 feet. In communications and information processing, encoding is a system of rules to convert information—such as a letter, word, sound, image, or gesture—into another form or representation, sometimes shortened or secret, for communication through a channel or storage in a medium. ...10 Encoding/decoding* Stuart Hall Traditionally, masscommunications research has conceptualized the process of communication in terms of a circulation circuit or loop. ABSs have a lower average energy level than subframes that carry data. 12A-C are heatmaps of received power distributions of three example city-scale environments, including a residential area, a stadium, and a city downtown, according to an example embodiment. Decoding is the reverse process. As we have already discussed, sampling and quantizati… IoT device 103c can detect overlaid signal 102c by monitoring the average energy levels of signal 102a. Identify your audience, albeit a single person or a large crowd, and research your audience's background. FIG. LTE signal 102a includes a frame containing ten subframes (labeled #0-#9) separated by control signals (e.g., control signal 204). An act of communication requires encoder- the speaker and decoder- the listener. In all communication processes, there is a natural belief or fear that the full magnitude of the message will not be received. There are many forms of encoding to choose from including verbal, graphic, musical, and animation.⦠Each subframe can be a high energy subframe, containing cell data, or a low energy subframe, ABS. Encoding is also used to reduce the size of audio and video files. Error detection and correction can be performed on the pattern of energy levels. The Encoding property was set to an encoding that is not ASCIIEncoding, UTF8Encoding, UTF32Encoding, UnicodeEncoding, one of the Windows single byte encodings, or … The disclosed apparatus and methods can be used to provide an energy efficient Internet of Things (IoT) communication method that can be deployed on a city-wide scale using existing infrastructure and that can target individual sensors or devices. The second representation of data can further include an identification indicator, and the command can induce a response in the IoT device if the identification indicator matches a unique identification indicator of the IoT device. The energy detector is configured to detect average subframe energy levels of a plurality of subframes during reception of at least one frame of data defined by a first communications protocol (e.g., Long-Term Evolution (LTE)). Communication will be interpreted in different ways based on the general feeling of the audience as well as the zeitgeist of the time. 1. is a diagram of an embodiment using existing Long-Term Evolution (LTE) network infrastructure. Using Huffman Encoding To Compress A File Can Reduce The Storage It Requires By A Third, Half, Or Even More, In Some Situations. Furthermore, because the relative location of the subframes within frames 601a -d does not affect signal 102a, the subframes can be positioned in the desired locations to encode a wide range of data in overlaid signal 102c without creating any interference with signal 102a. This is done using words, symbols, pictures, symbols and sounds.In regards to promotion/marketing communication encoding involves transforming the organizations ideas about a product into various forms/types of promotion: advertisements, press releases, sales promotions or a personal sales pitch. The IoT paradigm relies on an ability to deploy sensors and other devices at scale, in the order of thousands of devices spread across a city, and communicate, only when needed, with those devices in a coordinated and efficient manner to control their operations, retrieve data of interest, and/or preform other functions. This is because the probability of errors in detecting ABS increases with increase in the number of ABSs, which results in higher SER for higher rate R. The impact on SER of the error detection and correction technique (“EC”), illustrated in FIG. So decoding means interpreting the meaning of the message. Encoding is the process of transforming a set of Unicode characters into a sequence of bytes. FIG. Visual encoding is the process of encoding images and visual sensory information. This is where decoding enters into the equation. An example apparatus is a decoder including an energy detector and a processor. FIG. The ability to encode data comprising an additional signal 102c overlaid onto a primary signal 102a governed by existing communications protocol and produced by existing infrastructure is adaptable to a wide range of embodiments. (Novinger, 2001, p. 153). As we have already discussed, sampling and quantiza⦠The mapping table for R=2, 602b shows that locations of ABSs at subframes 1 and 4 in frame 601b is mapped to bits ‘0010,’ the location of ABS at subframes 3 and 7 in frame 601c is mapped to bits ‘1111,’ and the location of ABS at subframes 2 and 3 are mapped to bits ‘0111.’ Therefore, using the R-preamble conveyed by the ABS locations in frame 601a, the ABS locations for frames 601b -601d can be interpreted as encoding data ‘00111110111’ which comprises the overlaid signal 102c within signal 102a. In the case of software, the software may be any language capable of configuring a processor to perform operations disclosed herein. In the example embodiment, signal 102a contains four sets of four frames 701a -d and an additional frame 701e. For example, the location of ABSs 203a-d at positions 1, 3, 7 and 8 of the frame of LTE signal 102a can be represented by ‘0101000110’. FIGS. The example method includes generating a communications frame, in accordance with a first communications protocol (e.g., LTE), where the frame includes (i) a synchronization indicator, (ii) a first representation of data contained within at least one given subframe that, during transmission of the frame, has a subframe average energy, and (iii) at least one other subframe that, during transmission of the frame, has a subframe average energy less than the subframe average energy of the at least one given subframe. FIG. Sensors may have any type of on-board radio, ranging from ultra-low power Bluetooth Low Energy chips for proximity-based data reporting or long-range narrow-band transmission radios, such as, for example, LORA/Sigfox.

In an example embodiment, the first frame 601a is configured to have the locations of the low energy subframes encode information that conveys a rate-defining preamble, called the R-preamble. SER is much lower when error correction was used, giving less than 6% SER for a range up to 39 feet.
