WLAN allows devices to connect to the internet and each other wirelessly using radio waves or infrared signals. It provides flexibility, portability, mobility, and ease of installation compared to wired networks. Common applications of WLAN include use in medical, education, temporary situations, airlines, and emergency centers. WLANs operate in either ad hoc mode for direct peer-to-peer connections or infrastructure mode which uses an access point to connect to other networks. Technologies used include infrared, radio waves that comply with FCC regulations, and microwaves. WAP allows access to internet content and services on mobile devices by compressing web pages for smaller screens.

Conclusion
Wireless phone standards have a life of their own. You can tell, because they are spoken of reverently in terms of generations. There's Great-Granddad, whose pioneering story pre-dates cellular; Grandma and Grandpa 1G, or analog cellular, Mom and Dad 2G, or digital cellular; 3G wireless, 4G, 5G and so on. This is a survey report PPT on these technology.
Many more useful measurements could be taken in discrete manufacturing and process plant applications without the expense and labor related to wire and cables for some hard-to-reach applications. Wiring in manufacturing or process-plant settings, with the accompanying complex supporting infrastructure and labor, drops from high ceilings or trenching can add 10-fold or more to installation costs. It doesn’t have to be that way. Industrial wireless technologies can provide cost-effective reliable communications. Key considerations and application examples will be discussed by Dan Capano, owner and president of Diversified Technical Services Inc. Mark T. Hoske, content manager and editor with Control Engineering, will explain wireless trends based on Control Engineering research and will moderate the webcast.

WAP, HTTP and HTML5 Web Socket Architecture Analysis in Contemporary Mobile A...Editor IJCATR
Accessing current and accurate information anywhere and at anytime is becoming a growing interest nowadays. Wireless
Application Protocol (WAP) is an application protocol that creates an opportunity to access information of any interest from WAP
servers using mobile phones. WAP is an enabling technology based on the Internet client server architecture model, for developing
client application for handheld devices or other wireless terminal which usually have less powerful CPU’s, less memory, very
restricted power consumption, smaller and variant displays, phone keypads etc. This paper analyses the features of WAP in relation to
the well established HyperText Transfer Protocol (HTTP) technology, the web socket API innovations introduced in HTML5, the
recent improvements in mobile devices processing capacity by connecting to cloud services and how application can be developed on
them using modern tools. The features that are more adapted to client development of micro-devices are used for the technology
application test.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

2. WLAN
A wireless local area network (WLAN) links two or more devices using some
wireless distribution method (typically spread-spectrum ), and usually
providing a connection through an access point to the wider Internet.
WLAN uses the unlicensed Industrial, Scientific, and Medical (ISM) band that
different products can use as long as they comply with certain regulatory
rules.
WLAN is also known as Wireless Fidelity or WiFi in short.
There are many products which use these unlicensed bands along with
WLAN.
3. Wireless LANs provide
Flexibility
Portability
Mobility
Ease of Installation
5. Types of WLANS
The IEEE 802.11 has two basic modes of operation:
1. Ad hoc mode
2. Infrastructure mode
6. Ad hoc mode- In ad hoc mode, mobile units
transmit directly peer-to-peer.
7. Infrastructure mode- In infrastructure mode, mobile
units communicate through an access point that serves
as a bridge to other networks (such as Internet or LAN)
8. WIRELESS LAN TECHNOLOGIES:
In general , wireless LANs are categorized according to
the transmission technique which is employed.
Mainly 3 technologies are use din wireless LANs:
i. Infrared (IR) LANs
ii. Radio Waves LANs
iii. Microwave
9. 1. Infrared (IR) LANs
They use the same signal frequencies used on fiber optic links. IR
systems detect only the amplitude of the signal and so interference is
greatly reduced.
These systems are not bandwidth limited and thus can achieve
transmission speeds greater than the other systems.
Infrared transmission does not require a license from the FCC to
operate.
IR signals cannot penetrate opaque objects. This means that walls,
dividers, curtains, or even fog can obstruct the signal.
IR technology was initially very popular because it delivered high data
rates and relatively cheap price.
The drawbacks to IR systems are that the transmission spectrum is
shared with the sun and other things such as fluorescent lights.
10. 2. Radio Frequency
This type of LAN makes use of spread spectrum
transmission technology.
In general, these LANs operate in the ISM(Industrial,
Scientific and Medical) bands so that no FCC licensing
in needed for their use in United States.
Radio frequency systems must use spread spectrum
technology in the United States.
11. 3. Microwave
This type of LAN does not use spread spectrum.
These LANs operate at microwave frequencies.
Some of these products operate at frequencies that need
FCC licensing, while others use one of the unlicensed ISM
bands.
The big advantage to MW systems is higher throughput
achieved because they do not have the overhead involved
with spread spectrum systems.
12. Wireless Local Loop
WLL stands for Wireless Local Loop and it is basically the use of radio
to provide a telephone connection to the home. It is sometimes called
radio in the loop (RITL) or fixed-radio access (FRA).
WLL is a system that connects subscribers to the local telephone station
wirelessly.
When WLL connects subscribers to the public switched telephone
network (PSTN), radio signals are used as a substitute for copper for all
or part of the connection between the subscriber and the switch.
Included in this is: cordless access systems, proprietary fixed radio
access, and fixed cellular systems.
14. WAP- Wireless Application/
Access Protocol
An open, global specification that empowers mobile users with wireless devices to
easily access and interact with internet information and services instantly.
The wireless industry came up with the idea of WAP. The point of this standard was
to show internet contents on wireless clients, like mobile phones.
Wireless: Lacking or not requiring a wire or wires pertaining to radio
transmission.
Application: A computer program or piece of computer software that
is designed to do a specific task.
Protocol: A set of technical rules about how information should be
transmitted and received using computers.
15. WAP stands for Wireless Application Protocol
o WAP is an application communication protocol
o WAP is used to access services and information
o WAP is inherited from Internet standards
o WAP is for handheld devices such as mobile phones
o WAP is a protocol designed for micro browsers
o WAP enables the creating of web applications for mobile
devices.
o WAP uses the mark-up language WML (not HTML) WML
is defined as an XML 1.0 application
16. The basic AIM of WAP is to provide a web-like
experience on small portable devices - like mobile phones
and PDAs.
17. Purpose of WAP
To enable easy, fast delivery of relevant information and services to mobile users.
Type of devices that use WAP
Handheld digital wireless devices such as mobile phones, pagers, two-way radios,
smart phones and communicators -- from low-end to high-end.
WAP works with most Wireless networks such as:
CDPD, CDMA, GSM, PDC, PHS, TDMA, FLEX, ReFLEX, iDEN, TETRA, DECT,
DataTAC, Mobitex.
18. Operating systems that are compatible with WAP
•WAP is a communications protocol and an application environment.
•WAP is independent of OS that means WAP can be implemented on any
OS.
•It can be built on any operating system including Palm OS, EPOC 32,
Windows CE, FLEXOS, OS/9, Java OS, etc. It provides service interoperability
even between different device families.
19. Architecture Overview
WWW programming model is optimized and extended
to match characteristics of the wireless environment
Utilizes proxy technology to connect between the
wireless domain and WWW.
Before we describe WAP model, first we would like
you to understand how Standard Internet works.

The figure below shows the WAP programming model. Note, the
similarities with the Internet model. Without the WAP
Gateway/Proxy, the two models would have been practically
identical.
22. How WAP Model Works?
When it comes to actual use, WAP works like this:
The user selects an option on their mobile device that has a URL with Wireless
Markup language (WML) content assigned to it.
The phone sends the URL request via the phone network to a WAP gateway
using the binary encoded WAP protocol.
The gateway translates this WAP request into a conventional HTTP request for
the specified URL and sends it on to the Internet.
The appropriate Web server picks up the HTTP request.
The server processes the request just as it would any other request.
The Web server adds the HTTP header to the WML content and returns it to
the gateway.
The WAP gateway compiles the WML into binary form.
The gateway then sends the WML response back to the phone.
The phone receives the WML via the WAP protocol.
The micro-browser processes the WML and displays the content on the screen.
23. WAP Device
- Is used to access WAP applications and
content. It might be a PDA, handheld computer.
WAP Client
- Entity that receives content from Internet via a
WAP Gateway. This is usually the WAP Browser.
WAP Content/Origin/Application Server
- Element in the network where the information
or web/WAP applications resides.
24. WAP Proxy
- Acts both as a client and as a server in the network.
Typically has
Protocol gateway : translates requests from the WAP
protocol stack to WWW protocol stack
Content encoders and decoders : translate WAP content
into compact encoded formats to reduce the size of data
over the network
It allows content and applications to be hosted on
standard WWW servers and developed using proven
WWW technologies such as CGI scripting
25. WAP Gateway
- Intermediary element used to connect two different
types of network. It receives request directly from
the clients as if it actually were the origin server that
clients want to receive the information form. The
clients are usually unaware that they are speaking to
the Gateway.
WAP Browser
Software running on the WAP device that interprets the
WAP content arriving from the internet and decides how
to display it on WAP device.
26. WML
WML – Wireless Markup Language formerly
called HDML (Handheld Devices Markup
Language)
Is a tag language that allows the text portions of
Web Pages to be presented on cellular phones and
Personal Digital Assistants (PDAs) via wireless
access.
WML is used for delivering data to WAP.
27. ADVANTAGES
The ADVANTAGES that WAP can offer over these other methods are the following:
•open standard, vendor independent
•network-standard independent
•transport mechanism–optimized for wireless data bearers
•application downloaded from the server, enabling fast service creation and
introduction, as opposed to embedded software
28. DISADVANTAGES of WAP
Small screens: For web phones, there's an incredibly small viewing
area; palmtops are barely better.
Speed of access: All devices have slow access.
Limited or fragmented availability: Wireless web access is sporadic in
many areas and entirely unavailable in other areas.
Price: Many technology limitations are being addressed by higher-end
devices and services. But the entry price for a good wireless web
palmtop with decent display, keyboard, and speed is easily $700 to
$900, not including monthly access.
Lack of user habit: It takes some patience and overcoming the learning
curve to get the hang of it -- connecting, putting in an address, typing.
Users just aren't used to the idea and protocol yet.
