This document provides an overview and comparison of LoRa and NB-IoT low-power wide area network (LPWA) technologies. It discusses that both technologies were developed for applications requiring long battery life and low data rates. LoRa is an unlicensed standard based on chirp spread spectrum modulation, while NB-IoT is a licensed narrowband cellular standard developed by 3GPP. Key differences are that LoRa has lower device costs and supports higher latencies, while NB-IoT can leverage existing cellular networks and has higher data rates. In conclusion, LoRa is a new dedicated technology for IoT platforms, while NB-IoT uses existing cellular infrastructure.Understand LPWA tetchnologies (Sigfox and LoRa)

Rapid technological advances in the past made possible the miniaturization of network devices to meet the cost and power consumption requirements in IoT and M2M scenarios. What is missing in this picture is a radio technology with both long range capability and a very low cost footprint. Existing radio technologies such as 3G/4G or Short Range Radio do not aptly meet the requirements of IoT scenarios because they are either too expensive or are not able to provide the required range. Other wireless technologies are geared towards high bandwidth which is in most cases not a requirement for IoT.
Emerging LPWAN technologies such as ETSI LTN or LoRAWAN are poised for filling the gap by providing long range (up to 40km) and low power connectivity. These technologies allow low cost radio devices and operation thus enabling scaling up IoT applications.Wireless communication

Wireless communication allows for freedom from wires and instantaneous communication without physical connections. It provides global coverage for communication that can reach areas where wiring is infeasible or costly. Wireless communication transmits voice and data using radio waves without wires. It uses different frequency channels that can transmit information independently and in parallel. While wireless communication provides mobility and flexibility, it also faces security and physical obstruction issues compared to wired communication.

The document discusses N-gram graphs, which represent the proximity or co-occurrence of items in a text by modeling them as a graph. An N-gram graph is constructed by extracting n-grams from a text, determining their neighborhood based on a window size, and assigning edge weights based on co-occurrence frequencies. The document outlines the process for constructing N-gram graphs and describes their potential uses, including representing sets of items with a single graph, comparing graphs through clustering, and defining similarity measures between graphs. N-gram graphs aim to capture proximity information in a way that is domain-agnostic, allows different analysis levels, and can represent multiple texts with a single graph structure.Accurate indoor positioning system based on modify nearest point technique

In recent years, majority of researches are focused on localization system for wireless environment. These researches rely on localization using devices to track the entities. In this paper, we use, a recently proposed Device-free Passive (DfP) that uses Probabilistic techniques to track locations in large-scale real environment without the need of carrying devices. The proposed system uses the Access Points (APs) and Monitoring Point (MPs) that works by monitoring and processing the changes in the received physical signals at one or more monitoring points to detect changes in the environment. The system uses continuous space estimator to return multiple location while the mortal is in motion. Our results show that the system can achieve very high probability of detection and tracking with very few false positives.REDTACTON

This document discusses radar echo signals and multipath fading. It begins with an abstract that introduces multipath propagation as a phenomenon where radar signals take multiple paths upon reflection, in addition to the direct line of sight path. This can cause interference and fading effects. The document then provides background on radar systems and the radar range equation. It presents an approach to process received radar signals to isolate the main line of sight echo and discard weaker multipath signals. This involves analyzing signal amplitudes and retaining the highest value signal. The system components for implementing this approach include a fast microcontroller, computer, and lab link cable for programming the microcontroller using BASIC language software.Radar target detection simulation

It analyzes the performance of these techniques based on probability of detection and probability of false alarm under different signal-to-noise ratio levels and fading channel models (AWGN, flat fading, Rayleigh fading). The key findings are that matched filter detection has better performance than energy detection, but requires prior knowledge of the primary signal. Energy detection has lower complexity but performs poorly in low SNR scenarios.

In our previous research, we addressed the problem of automating the design of passive radio-frequency (PRF)
services. An optimal PRF surface is one that offers a maximum probability of localization at a minimum instrumentation
cost, i.e., a minimum number of surface-embedded passive RFID transponders. Our previous results were based on the
assumption that the signal distribution model of an individual RFID transponder can be approximated as a circle. The
problem of automated PRF surface design was then formulated as the problem of packing a surface with circles of a
given radius. However, in practice, this approach leads to some loss of optimality: some areas of the surface may not
be covered or too many transponders may be required. More exact methods are need for verifying and constructing signal
distribution models of surface-embedded RFID transponders that can be used by surface packing algorithms to optimize the
design. In this paper, we present the design and implementation of a Cartesian robot for verifying and constructing signal
distribution models of surface-embedded RFID transponders. A model is characterized by four high-level parameters: an
RFID transponder, an RFID antenna, an RFID reader, and a surface type. The robot moves an RFID reader-antenna unit
over a PRF surface, e.g. a carpet, and systematically collects readings for various antenna positions over the surface. The
collected readings are subsequently processed to verify or construct signal distribution models. We describe experiments
with the robot to verify the localization probability of automatically designed PRF surfaces. We also present experiments
with the robot to verify and construct the signal distribution models of a specific RFID transponder.Lightweight Neighborhood Cardinality Estimation in Dynamic Wireless Networks ...

Automatic target recognition (ATR) using recurrent neural networks (RNN) is being proposed in this work. When electromagnetic waves from radar illuminate the targets, surface currents are produced which result in scattering of incident energy. The scattered signal in the direction of radar is received as the radar signature of the target. The radar cross-section (RCS) is an important feature extracted from the radar signature that is used for target identification. The RCS values for each set of azimuth and elevation angles for a mono-static configuration serves the purpose of the dataset for the recurrent neural network (RNN)/long short-term memory (LSTM) model. The classification accuracy of 93 per cent was achieved using the RNN/LSTM model.

DASH7 is a wireless sensor network protocol that originated from ISO/IEC 18000-7 and was enhanced by the DASH7 Alliance to enable ultra low power, mid-range wireless sensor communication using sub-1GHz frequencies. It uses an asynchronous communication method involving command-response transactions and file notifications to allow for bursty, light, asynchronous, stealth, and transitional data transfer between sensors and gateways. An open source DASH7 protocol stack has been developed by CoSys-Lab and the DASH7 Alliance to support its use cases and provide a hardware-independent, full-stack solution for long range, low power, mobile wireless sensor applications.DASH7 Alliance Protocol Technical Presentation
DASH7 Alliance Protocol Technical PresentationMaarten Weyn

The Dash7 Alliance Protocol is based on ISO/IEC 18000-7, which describes parameters for active RFID communications at 433 MHz. It builds on an asynchronous wireless sensor network MAC protocol, with functionality optimized for RFID and support for fixed and mobile nodes to upload or retrieve small amounts of data. Dash7 uses GFSK modulation in the 433 MHz band and supports tag-to-tag communication through a simple routing protocol with a range that can be extended using subcontrollers.Multimodal Localization as the Key for Ambient Intelligent Applications
