Light Fidelity Technology

Li-Fi: The Future of Wireless Communication Through Light

Present Scenario

The demand for wireless data is skyrocketing — doubling every year — as billions of connected devices, from smartphones to smart homes, compete for limited radio bandwidth. Traditional Wi-Fi and cellular networks are now facing congestion like never before.

This growing challenge raises a critical question:
What technology can meet the future demand for high-speed, secure, and interference-free wireless communication?

The answer lies in Li-Fi (Light Fidelity) — an innovative technology that transmits data through light instead of radio frequencies.

How Li-Fi Works

The concept of Li-Fi is simple yet revolutionary.

Li-Fi uses LED lights to transmit data. When an LED is on, it transmits a digital 1. When it is off, it transmits a digital 0. These rapid on-off light variations (which are too fast for the human eye to detect) form binary data signals.

A Li-Fi controller encodes the data into the LED’s light waves, and a receiver — such as a photodiode — decodes these light signals back into digital information.

Essentially, any space illuminated by LED lights can become a high-speed data zone, transmitting information seamlessly and securely.

All that’s needed are LED light sources and intelligent controllers to modulate the light.

Why Visible Light Communication (VLC)?

The electromagnetic spectrum offers many forms of energy, but only the visible light spectrum is ideal for daily, human-safe data transmission. Here’s why:

• Gamma rays and X-rays are highly dangerous to human health.

• Ultraviolet light (UV) can cause biological damage.

• Infrared light (IR) is limited by eye-safety regulations and power restrictions.

The visible light spectrum — safe, abundant, and license-free — offers a clean and secure alternative.
This makes Visible Light Communication (VLC) the foundation of Li-Fi, paving the way for the next generation of wireless connectivity.

About Luxim (LAXIM)

Luxim, a clean-tech company based in Sunnyvale, California, was founded in 2000 and has been at the forefront of advanced lighting and Li-Fi solutions.

3. LIFI4KU – A mercury-based light source with strong UV spectral emission (down to 320 nm), used in UV curing, fluorescence imaging, and UV printing.

These technologies demonstrate how light-based systems can go beyond illumination — offering powerful, real-time data communication.

Potential Applications of Li-Fi

Li-Fi’s versatility opens up new possibilities across industries. Here are some key areas where it’s making an impact:

1. Smart Traffic Systems

Traffic lights equipped with Li-Fi can communicate with vehicles and nearby signals.
Cars using LED headlights and taillights can exchange data, preventing collisions and optimizing traffic flow — making roads safer and smarter.

2. Safe Industrial Environments

In sensitive zones like petrochemical plants, hospitals, and aircraft, where radio waves can interfere with equipment or pose hazards, Li-Fi provides a safe communication channel using harmless visible light.

3. Public Internet Hotspots

Imagine streetlights acting as high-speed internet hubs.
By integrating Li-Fi technology into street lamps, cities can create public data zones, offering connectivity wherever there’s light — a cost-effective step toward truly smart cities.

Conclusion

Li-Fi represents a transformational shift in wireless communication. By harnessing the power of light, it offers an ultra-fast, secure, and interference-free alternative to traditional Wi-Fi.

As research continues and infrastructure evolves, Li-Fi could soon redefine how the world connects — turning every beam of light into a gateway to the digital universe.

What is Blue Jacking?

Know Bluetooth Technology:

žBluetooth is a wireless networking standard created for personal area networks (PANs). Is was founded in 1994,as wireless data transmission technology using radio transmissions.žBluetooth is a cable replacement technology.

žBluetooth is an IEEE standard under the denomination of 802.15 WPANs.žž Bluetooth provides cheap connection between two or more devices.žžBluetooth has a short range of approximately 10 meters up to 25 meters.žžBluetooth offers low speeds of approximately 1Mbps.

What is Blue Jacking:

žBlue jacking exploits a Bluetooth device’s ability to discover other nearby devices to send unsolicited messages.žThe unsolicited message is then displayed on the victim’s device, potentially causing confusion or at least annoyance. Actually blue jacking allows individ

uals to send business cards anonymously using Bluetooth wireless technology. Bluejacking does not involve the removal or alteration of any data from the device. These business cards often have a clever or flirtatious message.

Features of Blue Jacking:

• žBluejacking does not involve the removal or alteration of any data from the device.ž
• žA bluejacker normally send only a text message, but now it has now become possible to send images or sounds also.ž
• ž Bluejacking exploits a Bluetooth device’s ability to discover other nearby Bluetooth devices.

How to Blue Jacking Done:ž

žIt is done with the help of OBEX protocol.ž

žTo choose the recipients of bluejacks, senders complete a scan using their mobile phones to search for the available Bluetooth-enabled devices in the immediate area.ž

žA bluejacker then picks one of the various available devices (that have their Bluetooth on), composes a message within the body of the phone’s contact interface, then sends the message to the receiver and stays close to the receiver to observe any reactions expressed by the person.ž

žThe message is sent via vCard functionality. It has a name field for bluedating or bluechat to another Bluetooth enabled device.žž

žIt also allows phone users to send business cards secretly using Bluetooth. These business cards can even contain clever or flirtatious messages instead of simply the phone number and name.ž

žBluejackers look for the receiving phone to ping or to react.

Fig. 1 how the sender sends the bluejack message

Fig. 2 what does receiver sees on the screen as it receives the bluejack message

Advantages of Blue jacking:ž

• žUsually, a bluejacker will only send a text message, but with modern phones it’s possible to send images or sounds as well.
• žWe can easily transfer data from mobile to laptop or from mobile to mobile in a short period.
• žWe can even enjoy music by wireless headphones through Bluejacking.

Disadvantages of Blue jacking:

• žIncrease in the availability of Bluetooth enabled devices, these devices have become vulnerable to virus attacks and even complete takeover of devices through a Trojan horse program.ž
• žThese may even cause irritation in any person as these are just unwelcomed messages or some jokes.ž
• žThey can annoy anyone very easily.

Usages of Blue Jacking:ž

žIt can be used in malls for advertisement purposes. As you cross their shop, you can get a message or any latest scheme they are providing on that day, etc.ž

žThey can be used at railway station to give you information about various general rules and about train timings, etc. Someone can even annoy you by sending useless messages. So, it is advisable to keep it off at these public places.ž

ž It can also be used at café, restaurant, cinema, mobile phone shop or at any electronic shop to provide you various information regarding them but any other random person can also send you the Bluejack messages and hence can even annoy you.

žHow to prevent yourself from Blue Jackers:

žPhone owners who receive bluejack messages should refuse to add the contacts to their address book. This means they must be fully ignored.ž

žDevices could be set in the non-discoverable, hidden or invisible mode in the menu. They are not prone to bluejacking.ž

žYou can turning off your Bluetooth device off at certain public areas like various shopping centers, coffee shops, movie theaters, bars and clubs, public transport vehicles, phone, at various electronic stores and even in parks.

There are two kinds of Cyber Bullying:

• Direct Attacks- messages sent directly to the victim.
• Cyber Bullying by Proxy– Using someone else to cyber bully a victim, this proxy may know they are cyber bullying and they may not.

1. Direct Attacks:

• Instant Messaging
• Text Messaging
• Blogs
• Websites
• Emailing Pictures
• Stealing Passwords
• Internet Polling- Hot or Not!
• Hacking or sending spyware

2. By Proxy:

• Someone else does the dirty work for the main cyber bully.
• Bullies may hack into the victim’s account or steal their password. They may set up a new account pretending to be the victim.
• Friends get angry with the victim.
• This form of cyber bullying is very dangerous because many people are involved, not just the bully and the victim.

Direct Attach Storage (DAS)

Introduction:

DAS is a type of storage that is connected directly to the server which enables quick access to the data but only through the server.

Direct-attached storage (DAS) is a basic level storage in which the host computer holds the storage devices or these can be connected to one server at a time. Networked workstations can access the data only through the host. DAS was the first storage model that gained widespread acceptance and is widely used. Even though networked storage models are gaining popularity, DAS still finds takers because it is easy to deploy and has a low initial cost of deployment. It helps if you have an idea of what your data availability needs are at present and what they will be in the future.

Storage System:

DAS is the most basic storage subsystem that provides block-level storage, and it’s the building block for SAN and NAS. The performance of a SAN or NAS is ultimately dictated by the performance of the underlying DAS, and DAS will always offer the highest performance levels because it’s directly connected to the host computer’s storage interface. DAS is limited to a particular host and can’t be used by any other computer unless it’s presented to other computers over a specialized network called a SAN or a data network as a NAS server.

There are the three basic types of storage.

• Direct Attached Storage (DAS),
• Storage Area Network (SAN),
• Network Attached Storage (NAS)

DAS is the basic building block in a storage system, and it can be employed directly or indirectly when used inside SAN and NAS systems. NAS is the highest layer of storage and can be built on top of a SAN or DAS storage system. SAN is somewhere between a DAS and a NAS.

SCSI — Small computer system interface is one of the oldest forms of storage interfaces traditionally used in server or workstation class computers.

PATA — Parallel advanced technology attachment (originally called ATA and sometimes known as IDE or ATAPI) was the most dominant desktop computer storage interface from the late 1980s until recently, when the SATA interface took over.

SATA — Serial advanced technology attachment is the official successor to PATA. So far, there have been two basic versions of SATA, with SATA-150 and SATA-300.

SAS — Serial Attached SCSI is the latest storage interface that’s gaining dominance in the server and storage market. SAS can be seen as a merged SCSI and SATA interface, since it still uses SCSI commands yet it is pin-compatible with SATA.

FC — Fibre channel is both a direct connect storage interface used on hard drives and a SAN technology. FC offers speeds of 100, 200, and 400 MB/s.

Flash — Flash memory isn’t a storage interface, but it is used for very high-end storage applications because it doesn’t have the mechanical latency issues of hard drives.

RAM — Random access memory is also not traditionally seen as a storage medium, but it can be used as an ultra-fast storage device.

The Surface Experience:

There are many features of windows surface some of the specials features ,i am showing here-

Direct Interaction-User can “grab” items with their hands and move data to different location on the hard disk or to removable devices. Easy touch navigation-without the use of a mouse and keyboard.

Object Recognition-Users can place physical objects such as drinks, cell phones, cameras, wines, food,laptops,mp3 players on the table to activate digital responses. And to see contents.

Multi-Touch Friendly-Recognizes several points of contact simultaneously as opposed to average single point of contact touch screens. Gives users the ability to be completing unrelated tasks simultaneously.

Multi-USer-Friendly- It’s design multi-touch capabilities make it a great gathering spot to share data, exchange ideas, and inspire group collaboration.

Internal Specification:

1)Screen: The Surface has an acrylic table top which a diff user makes capable of processing multiple inputs from multiple users. Objects can also be recognized by their shapes or reading.

2) Infrared: Infrared light is projected onto the underside of the diff user. Objects or fingers are visible through the diff user by series of infrared-sensitive cameras which are positioned underneath the surface of the tabletop.

3) CPU: This is similar to a regular desktop. The underlying operating system is a modified version of Microsoft Vista.

4) Projector: The Surface uses the same DLP light engine in many rear-projection tvs.

5) Cameras: 4 infrared cameras place inside the tabletop and that focus on screen and reads user interaction from four side and cover the whole screen.

How Does it works:

Digital Light processing is a technology used in newer Surface devices.

It allows recognition of fingers, hands, and objects that are placed on the screen, enabling vision-based interaction. Sensors in the individual pixels in the display register what is touching the screen.

A step-by-step look at how Pixel Sense works:

* When An object is placed on the display.

* An infrared back light illuminates the object.

* Light reflected back from the object is registered by cameras.

* Values reported from all of the cameras are used to create a picture of what is

on the display.

* The picture is analyzed using image processing techniques creating a

corrected image.

* The corrected sensor image and information about the objects placed on the

display are sent to the PC.

* And then surface system react according to the user requirement.

Hadoop Technology

Introduction:-

       Hadoop is a new technology. Hadoop is an open-source software framework for storing data and running applications on clusters of commodity hardware. It provides massive storage for any kind of data, processing power and the ability to handle virtually limitless concurrent tasks or jobs.

History:-

        As the World Wide Web grew in the late 1900s and early 2000s, search engines and indexes were created to help locate relevant information amid the text-based content. In the early years, search results were returned by humans. But as the web grew from millions of pages, automation was needed.

Why is Hadoop important?

• Ability to store and process huge amounts of any kind of data, quickly. With data volumes and varieties constantly increasing.
• Computing power.
• Fault tolerance.
• Flexibility.
• Low cost. The open-source framework is free and uses commodity hardware to store large quantities of data.
• Scalability. You can easily grow your system to handle more data simply by adding nodes. Little administration is required.

What are the challenges of using Hadoop?

• MapReduce programming is not a good match for all problems.
• There’s a widely acknowledged talent gap.
• Data security– it is also provide data security for hadoop and big data users.
• Full-fledged data management and governance. Hadoop does not have easy-to-use, full-feature tools for data management, data cleansing, governance and metadata.

How Is Hadoop Being Used?

• low-cost storage and data archive.

  

• Sandbox for discovery and analysis.
• Data Lake.
• Complement your data warehouse.
