2. Wireless….
• Wireless communication is the transfer of information or power between
two or more points that are not connected by an electrical conductor. The
most common wireless technologies use radio. With radio waves distances
can be short, such as a few meters for television or as far as thousands or
even millions of kilometers for deep-space radio communications. It
encompasses various types of fixed, mobile, and portable applications,
including two-way radios, cellular telephones,personal digital
assistants (PDAs), and wireless networking. Other examples of applications
of radio wireless technologyinclude GPS units, garage door openers,
wireless computer mice, keyboards and headsets, headphones, radio
receivers,satellite television, broadcast television and cordless
telephones.

3. Mobile Telephones….
• One of the best-known examples of wireless technology is
the mobile phone, also known as a cellular phone, with more than
4.6 billion mobile cellular subscriptions worldwide as of the end of
2010. These wireless phones use radio waves from signal-
transmission towers to enable their users to make phone calls
from many locations worldwide. They can be used within range of
the mobile telephone site used to house the equipment required
to transmit and receive the radio signals from these instruments

5. Data Communications…
• Wireless data communications are an essential component of mobile
computing. The various available technologies differ in local availability,
coverage range and performance, and in some circumstances, users must
be able to employ multiple connection types and switch between
them. To simplify the experience for the user, connection manager
software can be used, or a mobile VPN deployed to handle the multiple
connections as a secure, single virtual network.Supporting technologies
include:
• Wifi
• Cellular Data Services
• Mobile Satellite Communications
• Wireless Sensor Networks

6. Wi-Fi
• Wi-Fi is a wireless local area network that enables portable
computing devices to connect easily to the Internet. Standardized
as IEEE 802.11 a,b,g,n, Wi-Fiapproaches speeds of some types of
wired Ethernet. Wi-Fi has become the de facto standard for access
in private homes, within offices, and at public hotspots.Some
businesses charge customers a monthly fee for service, while
others have begun offering it for free in an effort to increase the
sales of their goods

8. Other Data Communications….
• Cellular data service offers coverage within a range of 10-15 miles from
the nearest cell site.Speeds have increased as technologies have evolved,
from earlier technologies such as GSM, CDMA and GPRS, to 3G networks
such as W-CDMA, EDGE or CDMA2000.
• Mobile Satellite Communications may be used where other wireless
connections are unavailable, such as in largely rural areas or remote
locations.Satellite communications are especially important
or transportation, aviation, maritime and military use.
• Wireless Sensor Networks are responsible for sensing noise, interference,
and activity in data collection networks. This allows us to detect relevant
quantities, monitor and collect data, formulate clear user displays, and to
perform decision-making functions

9. Wireless Energy Transfer….
• Wireless energy transfer is a process whereby electrical energy is
transmitted from a power source to an electrical load (Computer
Load) that does not have a built-in power source, without the use
of interconnecting wires. There are two different fundamental
methods for wireless energy transfer. They can be transferred
using either far-field methods that involve beaming power/lasers,
radio or microwave transmissions or near-field using induction.
Both methods utilize electromagnetism and magnetic fields

11. Medical Technology….
• New wireless technologies, such as mobile body area networks
(MBAN), have the capability to monitor blood pressure, heart rate,
oxygen level and body temperature. The MBAN works by sending
low powered wireless signals to receivers that feed into nursing
stations or monitoring sites. This technology helps with the
intentional and unintentional risk of infection or disconnection
that arise from wired connections.

12. Computer interface devices….
• Answering the call of customers frustrated with cord clutter, many manufacturers of
computer peripherals turned to wireless technology to satisfy their consumer
base.Originally these units used bulky, highly local transceivers to mediate between
a computer and a keyboard and mouse; however, more recent generations have
used small, high-quality devices, some even incorporating Bluetooth. These systems
have become so ubiquitous that some users have begun complaining about a lack of
wired peripherals. Wireless devices tend to have a slightly slower response time
than their wired counterparts; however, the gap is decreasing.
• A battery powers computer interface devices such as a keyboard or mouse and send
signals to a receiver through a USB port by the way of a radio frequency (RF)
receiver. The RF design makes it possible for signals to be transmitted wirelessly
and expands the range of efficient use, usually up to 10 feet. Distance, physical
obstacles, competing signals, and even human bodies can all degrade the signal
quality. Concerns about the security of wireless keyboards arose at the end of 2007,
when it was revealed that Microsoft's implementation of encryption in some of its
27 MHz models was highly insecure

13. Tablet Computers….
• A tablet computer, commonly shortened to tablet, is a thin, flat mobile
computer with a touchscreen display, which in 2016 is usually color,
processing circuitry, and a rechargeable battery in a single device. Tablets often
come equipped with sensors, including digital cameras, a microphone, and
an accelerometer. The touchscreen display uses the recognition of finger or
stylus gestures to replace the mouse, trackpad and keyboard used in laptops.
They usually feature on-screen, pop-up virtual keyboards for typing and
inputting commands. Tablets may have physical buttons for basic features such
as speaker volume and power, and ports for plugging in network
communications, headphones and battery charging. Tablets are typically larger
than smartphones or personal digital assistants with screens 7 inches (18 cm) or
larger, measured diagonally.Tablets have Wi-Fi capability built in so that users
can connect to the Internet and can have cellular network capabilities

15. Wireless Security….
• Wireless security is the prevention of unauthorized access or damage to
computers using wireless networks. The most common types of wireless
security are Wired Equivalent Privacy (WEP) and Wi-Fi Protected
Access (WPA). WEP is a notoriously weak security standard. The password
it uses can often be cracked in a few minutes with a basic laptop
computer and widely available software tools. WEP is an old IEEE 802.11
standard from 1999, which was outdated in 2003 by WPA, or Wi-Fi
Protected Access. WPA was a quick alternative to improve security over
WEP. The current standard is WPA2; some hardware cannot support WPA2
without firmware upgrade or replacement. WPA2 uses an encryption
device that encrypts the network with a 256-bit key; the longer key
length improves security over WEP.

16. Wireless Security Cameras….
• Wireless security cameras are closed-circuit television (CCTV) cameras that
transmit a video and audio signal to a wireless receiver through a radio band.
Many wireless security cameras require at least one cable or wire for power;
"wireless" refers to the transmission of video/audio. However, some wireless
security cameras are battery-powered, making the cameras truly wireless from
top to bottom.
• Wireless cameras are proving very popular among modern security consumers
due to their low installation costs (there is no need to run expensive video
extension cables) and flexible mounting options; wireless cameras can be
mounted/installed in locations previously unavailable to standard wired
cameras. In addition to the ease of use and convenience of access, wireless
security camera allows users to leverage broadband wireless internet to provide
seamless video streaming over-internet.

18. E-Books….
• An electronic book (or e-book) is a book publication made available in digital
form, consisting of text, images, or both, readable on the flat-panel display of
computers or other electronic devices. Although sometimes defined as "an
electronic version of a printed book“, some e-books exist without a printed
equivalent. Commercially produced and sold e-books are usually intended to be
read on dedicated e-reader devices. However, almost any sophisticated
computer device that features a controllable viewing screen can also be used to
read e-books, including desktop computers, laptops, tablets andsmartphones.
• In the 2000s, there was a trend of print and e-book sales moving to
the Internet, where readers buy traditional paper books and e-books
on websites using e-commerce systems. With print books, readers are
increasingly browsing through images of the covers of books on publisher or
bookstore websites and selecting and ordering titles online; the paper books are
then delivered to the reader by mail or other delivery service (e.g., FedEx).

19. Wireless USB….
• Wireless USB is a short-range, high-bandwidth wireless radio communication
protocol created by the Wireless USB Promoter Group which intends to further
increase the availability of general USB-based technologies. It is maintained by
theWiMedia Alliance and (as of 2009) the current revision is 1.0, which was
approved in 2005. Wireless USB is sometimes abbreviated as "WUSB", although
the USB Implementers Forum discouraged this practice and instead prefers to
call the technology Certified Wireless USB to distinguish it from the competing
UWB standard.
• Wireless USB was based on the (now defunct) WiMedia Alliance's Ultra-
WideBand (UWB) common radio platform, 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
metres (33 ft). It was designed to operate in the 3.1 to 10.6 GHz frequency
range, although local regulatory policies may restrict the legal operating range
in some countries.

20. Wireless Sensor Network….
• Wireless sensor networks (WSN), sometimes called wireless
sensor and actuator networks (WSAN),are spatially
distributed autonomous sensorsto monitor physical or
environmental conditions, such as temperature, sound,pressure,
etc. and to cooperatively pass their data through the network to a
main location. The more modern networks are bi-directional, also
enablingcontrol of sensor activity. The development of wireless
sensor networks was motivated by military applications such as
battlefield surveillance; today such networks are used in many
industrial and consumer applications, such as industrial process
monitoring and control, machine health monitoring, and so on.
