ZigBee is a wireless networking standard used for control and sensor applications that requires low data rates, low power consumption, and secure networking. It is based on the IEEE 802.15.4 standard and allows for up to 65,000 nodes to connect in a mesh network topology. ZigBee operates in the 2.4GHz, 868MHz, and 915MHz frequency bands and is designed for use in personal area networks for applications like home automation, lighting control, and wireless sensor networks. Research is ongoing to expand ZigBee's uses in fields like wireless communications and neuroengineering.

GI-FI (Gigabit Fidelity) or Giga bit wireless refers to wireless communication at a data rate of more than one billion bits (gigabits) per second. GI-FI offers some advantages over WI-FI, a similar wireless technology. In that it offers faster information rate in GBPS, less power consumption and low cost for short range transmission as compare to current technology. GI-FI consists of a chip which has facility to deliver short-range multi gigabit data transfer in a local environment and compared to other technologies in the market it is ten times faster. GI-FI has the data transfer speed up to 5 GBPS within a short-range of 10 metres. It operates in 60 GHZ frequency band. GI-FI is developed on an integrated wireless transceiver chip. It has both transmitter and receiver, integrated on a single chip which is fabricated using the CMOS (complementary metal oxide semiconductor) process and it also consists of a small antenna. GI-FI allows transferring large videos, audio files, data files etc. within few seconds.

A SURVEY OF THE S TATE OF THE A RT IN Z IG B EEIJCI JOURNAL
ZigBee is one of the most widely used wireless comm
unication technologies. ZigBee is being widely used
for sensor communications and many other research f
ields. Why consider ZigBee? Because it is cheap and
has better compatibility when compared to other com
munication technologies. We have given a detailed
description on comparison between all the available
technologies. In this paper, we have discussed so
me
basic concepts about ZigBee and its security aspect
s in networking. We have also listed out the major
manufacturers who are into the production of the tr
ansceivers for ZigBee
Gas leakage is an important problem. It wastes energy and sometimes it causes harmful effects to lives. We have limited energy resources. Proper utilization of resources is need of the time. We have proposed a gas safety management system
using ZigBee to monitor flow and pressure of gas, earthquake, temperature, smoke and leak of methane. It also provides a health safety system simultaneously by automating the associated devices with its embedded programmed feature to procure the environment by completely eradicating the harmful source. Through this dynamic technology, we can establish a well economic and health caring system in this
rapidly developing era to excel our country.
ZigBee is the name of a specification for a suite of high level communication protocols using small, low-power digital radios based on the IEEE 802.15.4-2006 standard for wireless personal area networks (WPANs), such as wireless headphones connecting with cell phones via short-range radio. The technology is intended to be simpler and less expensive than other WPANs, such as Bluetooth. ZigBee is targeted at radio-frequency (RF) applications that require a low data rate, long battery life, and secure networking.
After the read, you will learn the characteristics of the 6 wireless protocols IEEE protocols: LoRa, NB-IoT, ZigBee, Wi-Fi, BLE, WiMax.
In the field of IoT, a wide range of communication technologies wireless protocols exist simultaneously. In terms of transmission distance, there are BLE, WI-FI, ZigBee, sub1G, etc., which are widely used in the context of local wireless networks, such as wearable, home, and enterprise applications.
Zigbee operates in the industrial, scientific and medical radio bands; 868 MHz in Europe, 915 MHz in countries such as USA and Australia and 2.4 GHz in most jurisdictions worldwide. The technology is intented to be simpler and less expensive than other WPANS such as bluetooth. Radios are also avaiable stand lone to be used with any processor or microcontroller.
Implementation of MSK Modulation Scheme for Zigbee System / IEEE 802.15.4 Phy...ijtsrd
In this work physical layer simulation of IEEE 802.15.4 / ZigBee protocol has been done. The proposed work is the implementation of ZigBee system according to the protocol description. In this work we have simulated ZigBee system first with conventional OQPSK modulation technique, then the simulations are performed for MSK modulation, which is through OQPSK modulation. Simulation results for BER showing the average 79.43 % improvement in BER for Proposed MSK compared with OQPSK modulation scheme. For a target BER of 10-2 the SNR required is 4 dB for this work i.e. for MSK, as compared to 10 dB for conventional OQPSK. Hence, an improvement of 6 dB less SNR. For a target BER of 10-2 the SNR required is 4 dB for this work i.e. for MSK, as compared to 5.2 dB with [1]. Hence, an improvement of 1.2 dB less SNR.

Impact of Frequency Offset on Interference between Zigbee and Wifi for Smart ...IOSR Journals
Abstract: The Zigbee is a low cost communication technology used for low data rate communication system such as industrial automation etc. Because of its low complexity it is widely adopted for many applications. But the utilization of the same spectrum band by the WLAN system causes interference between both the systems. The proposed approach presents an analysis of this interference effect on Zigbee system when operated with WLAN sources at different distances and different power. It also analyzes the effect when a frequency offset is established between both systems. The simulation results shows that a small offset can provide sufficient improvement in the performance.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.
