Gi fi
Gi-Fi or gigabit wireless refers to a wireless communication at a data rate of more than one billion bits (gigabit) per second.
By 2004 some trade press used the term "Gi-Fi" to refer to faster versions of the IEEE 802.11 standards marketed under the trademark Wi-Fi.[1]
In 2008 researchers at the University of Melbourne demonstrated a transceiver integrated on a single integrated circuit (chip) that operated at 60 GHz on the CMOS process.[2] It will allow wireless transfer of audio and video data at up to 5 gigabits per second, ten times the current maximum wireless transfer rate, at one-tenth the cost. Researchers chose the 57–64 GHz unlicensed frequency band since the millimetre-wave range of the spectrum allowed high component on-chip integration as well as the integration of very small high gain arrays. The available 7 GHz of spectrum results in very high data rates, up to 5 gigabits per second to users within an indoor environment, usually within a range of 10 metres.[2] Some press reports called this "GiFi".[3][4] It was developed by Melbourne University-based laboratories of NICTA (National ICT Australia Limited), Australia’s Information and Communications Technology Research Centre of Excellence.[3]
In 2009, the Wireless Gigabit Alliance was formed. It used the term "WiGig" which avoided trademark confusion
Timeline: History of the Internet
- In the 1960s, J.C.R. Licklider wrote about his concept of an Intergalactic Network that would connect everyone globally, and the ARPANET was developed beginning in 1967 to link computers between research institutions.
- By the 1970s, the ARPANET had grown to connect over 30 institutions across industry, government, and academia.
- In the 1980s, the ARPANET transitioned to TCP/IP and was split between the public ARPANET and classified MILNET, personal computers like the Apple II expanded the consumer market, and networks like CSNET and BITNET connected additional institutions.

A futuristic approach for towerless mobile networks wheezy pi
It is an attempt to develop the mobile networks to
have a wireless voice call happening without the help of the
towers. Our main aim is to remove the towers in the
communication process. The towers have been hazardous to
Living Organism. This project mainly consists of Raspberry pi
and Wi-Fi router. We used two raspberry pi kits of version 3
with Wi-Fi inbuilt on it which can access till the distance of 30
meters,which is used to develop a voice call application to
transfer the voice through the Wi-Fi communication. It would be
possible to expand this communication by the use of WIMAX
which would be able to communicate in the range of kilometers.
For live transmission of audio and video, we have used VOIP
(voice over internet protocol) with the help of gstreamer and gstlaunch
libraries, IEEE standard 802.11 for wireless network,
LCD screen for GUI interface ,programmed in Python language
as it is recommended by Raspberry pi foundation and is freely
available for LINUX, Windows operating system. A hardware
implementation is developed and the results were analyzed for
performance.

The Japanese yen has strengthened significantly against other currencies like the US dollar in recent years. This poses challenges for Japan's export-driven economy. A strong yen makes Japanese exports more expensive overseas, reducing demand. It also decreases the value of overseas earnings for Japanese companies. Additionally, a strong yen contributes to deflationary pressures in Japan by making imports cheaper, weakening domestic consumption. The Japanese government has implemented measures like monetary easing and stimulus spending to support small businesses and domestic industries affected by the appreciating yen.

Mutation Testing for Task-Oriented Chatbots
Conversational agents, or chatbots, are increasingly used to access all sorts of services using natural language. While open-domain chatbots - like ChatGPT - can converse on any topic, task-oriented chatbots - the focus of this paper - are designed for specific tasks, like booking a flight, obtaining customer support, or setting an appointment. Like any other software, task-oriented chatbots need to be properly tested, usually by defining and executing test scenarios (i.e., sequences of user-chatbot interactions). However, there is currently a lack of methods to quantify the completeness and strength of such test scenarios, which can lead to low-quality tests, and hence to buggy chatbots.
To fill this gap, we propose adapting mutation testing (MuT) for task-oriented chatbots. To this end, we introduce a set of mutation operators that emulate faults in chatbot designs, an architecture that enables MuT on chatbots built using heterogeneous technologies, and a practical realisation as an Eclipse plugin. Moreover, we evaluate the applicability, effectiveness and efficiency of our approach on open-source chatbots, with promising results.
