Wi-Fi is a wireless technology that allows devices to connect to the internet or communicate with one another wirelessly. It uses radio waves to transmit data over short distances without wires. Wi-Fi networks rely on access points that connect wireless devices to a wired network. Access points work by sending and receiving radio signals that enable wireless devices on the network to share internet connections. Wi-Fi offers benefits like mobility and lower installation costs compared to wired networks. Its popularity continues to grow as more devices become Wi-Fi enabled.
Wi-Fi (Wireless Fidelity) is a generic term owned by "WiFi Alliance" which refers to any Wireless Local Area Networks (WLANs) based on IEEE 802.11 standard.

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

4. What is Wi-Fi?
Wi-Fi is the commercial name given to the
IEEE 802.11b communications standard for
Wireless Local Area Networks (WLANs).
Wi-Fi allows you to connect to the Internet
from an airport or coffee shop, or retrieving
files or presentations from the corporate
network or sending instant messages to co-
workers while sitting in a conference room at
work without wires.
5. Types of Wi-Fi technology
802.11a – It provides speed up to 54
Mbps in the 5GHz band.
802.11b (also referred to as 802.11
High Rate or Wi Fi) – It provides 11
Mbps transmission in the 2.4 GHz band.
802.11g – It provides 20+ Mbps in the
2.4 GHz band
7. Types of Wi-Fi Radios
PC Card Radio - Many laptop
computers and mobile
computing devices come with
a Wi-Fi radio built in. For
most other laptops you will
insert a Wi-Fi radio
embedded in a simple PCMCIA
card, commonly called a PC
Card, into the laptop's
expansion slot.
USB Radio - Most vendors
don't provide slots for PC
Cards, so the simplest method
is to use a USB Wi-Fi radio
that plugs into an available
USB port on your desktop
computer. Install the
software and you're up and
running.
8. Access Points
Access point - a
hardware device that
serves as a hub to
provide a wireless
connection to a wireless-
enabled computer.
Currently have range of
up to 300 feet.
9. Unlike hardware solutions, Software access
points have extensive configuration
flexibility but may not offer the full range of
wireless features defined in the 802.11
standard.
Fig.2 Software Access PointFig.1 Hardware Access Point
10. How do Access Points work?
The base station sends
and receives radio
signals to and from the
Wi-Fi radio in your
laptop or PC, through
access point enabling
you to share your
Internet connection
with other users on
the network.
Fig.3 Working of Access
Point
11. Multiple access points or extension points can be
used which extend the range of a single access point.
.
A user can move from Area 1 to Area 2
transparently making use of the concept of roaming
Fig.4 Extension
Point
Fig.5 Roaming
12. Security Features
VPN - Works by creating a secure virtual
"tunnel" from the end-user's computer
through the end-user's access point or
gateway, through the Internet, all the way
to the corporation's servers and systems.
Fig.6 Virtual Private
13. Firewalls - Firewalls can
make your network appear
invisible to the Internet,
and they can block
unauthorized and unwanted
users from accessing your
files and systems.
MAC Filtering - Every Wi-Fi radio has its unique MAC
number. Wi-Fi access points are programmed to accept only
certain MAC addresses and filter out all others.
RADIUS - RADIUS is a user name and password scheme
that enables only approved users to access the network; it
does not affect or encrypt data.
Hardware Firewall
14. Benefits of Wi-Fi
Wi-Fi can become one of the main enablers
to the vision of omnipresent computing.
Wi-Fi is one of the leading candidates to
bring Internet access to new environments
that were previously limited by the cost of
physically connecting through cables.
If you don't want to have each computer
on the network all the time, you can save
money by sharing the PC Cards or the USB
radio/adaptors for your laptops and other
mobile computing devices.
15. Comparative Study
Bluetooth has a shorter range restricted to
just 10 meters (40 feet) & maximum data
transfer capacity is around 1 Mbps.
Bluetooth seems to be the king in the very
short range.
Bluetooth is just a cable replacement and
not a real technology like Wi-Fi.
3G has strong qualities in truly Mobile
connectivity, but at a high cost and low data
transfer rates.
16. Wi-Fi’s strengths are
speed & range, which
makes it well suited to
networking.
Bluetooth’s low power
consumption makes it
great for mobile devices.
Bluetooth is for wireless
point to point connections
& Wi-Fi is for wireless
network connectionsFig.7 Comparison of Wi-Fi,
Bluetooth and 3G
17. And Lastly…The Inference
As a concluding note it is important for us
to know that getting a secure network with
fast processes is necessary irrespective of
the technology implemented. Wi-Fi not only
allows us to send and receive data or surf
the net from out of the office or while
waiting for a flight at the airport, at a
coffee shop , while holidaying at a resort ,
but also is cost effective as the wiring costs
are saved !
Thus, the best thing of all Wi-Fi is fast. In
fact its several times faster than the
fastest cable-modem connection.
