Wireless USB products are finally arriving at the market and in this article you will learn more about this technology and see some usage examples. The goals of wireless USB is to connect peripherals such as printers, externals hard disk drives, sound cards, media players and even video monitors to the PC wirelessly. This can be done by to forms.
If the PC and the device don’t have native support to WUSB, you must install a dongle to convert are standard USB ports in to WUSB.
The maximum theoretical transfer rate from WUSB in this same as USB 2.0:480mpbs if the device is within 3 meters from the PC or 110mpbs from the PC. As you can see, the more distant the devices are from the PC, lower is the transfer rate.
Bluetooth is another wireless technology that allows the connection between the PC and peripherals without wires. At this time, however, Bluetooth is targeted to low speed devices only, as its maximum transfer rate is of 1 Mpbs (128 kb\s) or 3Mpbs (384MB\s), depending on the Bluetooth generation.
The next Bluetooth generation is scheduled to have the same transfer rate as WUSB, but this technology is not yet available. Wireless USB works on the UWB frequency range, while Bluetooth technology works on 2.4GHz frequency, the same use by IEEE 802.11 wireless network.
The first Wireless USB implementations will likely be in the form of discrete
silicon that will be introduced in a number of form factors. These may include add-in
cards and dongles along with embedded solutions to support the technology's
introduction and subsequent rapid ramp up.
But the wireless future will arrive once WUSB, along with the common ultra
wideband platform, becomes a standard part of every processor and chipset and is
integrated in CMOS silicon.
As the latest iteration of USB technology, wireless USB (WUSB) will offer
the same functionality as standard wired USB devices but without the cabling. As the
new Wireless USB Promoter Group prepares to develop the specifications that will
help standardize the technology, the industry is planning products that can take
advantage of the convenience and mobility that this new device interconnect will
offer.

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.

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.

3. USB
• USB, short for Universal Serial Bus
• it is a standard plug-and-play type of connection for many kinds of devices.
• • USB is intended to replace many varieties of serial and parallel ports
• USB refers to the types of cables and connectors used to connect many types of
external devices to computers.
• setting up communication between a computer and peripheral devices.
• USB has become the standard connection method. USB was designed for personal computers
, as a power cord between a device and an adapter plugged into a wall plug for charging with
help of cable.

4. WUSB
• Wireless USB is sometimes abbreviated as "WUSB”
• Wireless USB is a short-range, high-bandwidth wireless radio communication protocol
created by the wireless USB promoter group.
• which is capable of sending 480 Mbit/s at distances up to 3 metres (9.8 ft) and 110 Mbit/s
at up to 10 meters (33 ft). It was designed to operate in the 3.1 to 10.6 GHz frequency
range.
• The basic transport mechanism for Wireless USB is the ultra-wide band (UWB) radio
platform.

All devices that use RF signals for
communication are known as wireless devices.
Some examples of these devices are walkie-talkies,
baby monitors, phones, tablets, Bluetooth mice and
keyboards, wireless routers, etc.. 6
7. Features of WUSB
• Wireless USB will build on the success of Wired USB. An important goal of
the WUSB Promoter Group is to ensure that wireless USB offers users the
experience they have come to expect from wired USB. Toward that end, the
Wireless USB standard is being designed to support the following features:
Easy Migration Path : -
• To enable an easy migration path from wired USB, Wireless USB will maintain the
same usage models and architecture as wired USB.
7
8. High performance:-
• At launch, Wireless USB will provide speeds up to 480 Mbps within 10 feet beyond will
be 110 Mbps , a performance comparable to the wired USB 2.0 standard
• High enough to provide wireless transfer of rich digital multimedia formats. As UWB
technology and process technologies evolve, bandwidth may exceed 1 Gb per second.
Simple, Low Cost Implementation:-
• Implementation will follow the wired USB connectivity models as closely as possible
to reduce development time and preserve the low-cost, ease-of-use model that has
made wired USB the interconnect of choice.
8
9. Backward compatibility : -
• Wireless USB will be fully backward compatible with the one billion wired USB
connections already in operation. Checking whether a devolved software is
compatibility with older version of other software .
• allows up to 127 devices to connect directly to a host. Because there are no wires or
ports, there is no longer a need for hubs.
• However, to facilitate the migration from wired to wireless, Sometimes referred to as a
"WUSB hub", allows existing USB 2.0 devices to be used wirelessly with a WUSB host.

10. Typical Home Applications
• PCs and peripherals
• PDAs
• External storage devices (HDDs)
• HDTV's and STB’s
• Game consoles
• Digital cameras
• Digital camcorders
• DVD players
• MP3 players
• CD players
• Wireless speakers
10
12. Wi-Fi Wireless USB Adapters
• Essential for a high-quality Internet connection – WiFi
adapters are designed to offer the best connections
available. External Wi-Fi adapters commonly plug into
the USB port of a computer.
• These adapters are casually called "wireless USB"
although the protocol used for signalling is Wi-Fi.
• The network adapter allows the device to communicate
over the local area network (LAN), connecting to the
internet or to other computers. Wireless network
adapters, such as those on laptop computers and
tablets, take the computer's signals and convert them
into radio waves that transmit via antenna (visible or
hidden).
12
13. Other Wireless USB Technologies
Various wireless USB adapters also exist supporting alternatives to Wi-Fi:
• Bluetooth
• IrDA infrared
• Other proprietary signalling technology
13
14. SECURITY & DEVICE ASSOCIATION
• WUSB security will ensure the same level of security as wired USB.
• wireless interconnect is that it is easy to install and use.
• Higher levels of security involving encryption should be implemented at the
application level.
14
15. Advantage
• You can connect wirelessly.
• It is the easy and secure from plugging it in / unplugging it
• You do not need to have a network cable between the device and the network.
• You can connect fairly easily at home, work, multiple offices (since there is no
cable to carry around or leave behind).
• You can move around or work at any available or suitable location without having
to be near a socket.
15
16. DISADVANTAGES
• Unless the security is not properly setup, both your laptop or desktop and the
network you are connecting to cannot be compromised and your data can be
accessed and read by others.
• The hardware is small, it can get damaged, lost or stolen.
• Reception is limited by distance and concrete and natural structures between
you and the antenna (radio waves don't always propagate in a linear fashion in
building, they get blocked by steel or concrete structures).
• Some older wireless networks can get very slow if there are lots of people in
the same area, all trying to use the network (effectively trying to use the same
radio bandwidth). 16
