    WIRELESS TEC H NOLOGIES

    Wireless is a term used to describe telecommunications in which electromagnetic waves

    (rather than some form of wire) carry the signal over part or all of the communication path.

    Some monitoring devices, such as intrusion alarms, employ acoustic waves at frequencies

    above the range of human hearing; these are also sometimes classified as wireless. In simple

    words transformation of data without any wire.

    The first wireless transmitters went on the air in the early 20th century using radiotelegraphy

    (Morse code). Later, as modulation made it possible to transmit voices and music via

    wireless, the medium came to be called "radio." With the advent of television, fax, datacommunication, and the effective use of a larger portion of the spectrum, the term "wireless"

    has been resurrected.

    Common examples of wireless equipment in use today include:

    Cellularphones and pagers -- provide connectivity for portable and mobile applications,

    both personal and business

    Global Positioning System (GPS) -- allows drivers of cars and trucks, captains of boats

    and ships, and pilots of aircraft to ascertain their location anywhere on earth

    Cordless computer peripherals -- the cordless mouse is a common example; keyboards

    and printers can also be linked to a computer via wireless

    Cordless telephone sets -- these are limited-range devices, not to be confused with cell

    phones

    Home-entertainment-system control boxes -- the VCR control and the TV channel

    control are the most common examples;

    Wifi

    Bluetooth

    WIFI

    Wi-Fi is a mechanism that allows electronic devices to exchange data wirelessly over

    a computer network. A device enabled with Wi-Fi, such as a personal computer, video game

    console, smartphone, tablet, or digital audio player, can connect to a network resource such

    as the Internet via a wireless networkaccess point. An access point (orhotspot) has a range

    of about 20 meters (65 ft) indoors and a greater range outdoors. Hotspot coverage can

    comprise an area as small as a single room with walls that block radio signals or a large area,

    as much as many square miles, covered by multiple overlapping access points.

    "Wi-Fi" is a trademarkof the Wi-Fi Alliance and the brand name for products using the IEEE802.11 family of standards. Only Wi-Fi products that complete Wi-Fi

    Alliance interoperabilitycertification testing successfully may use the "Wi-Fi CERTIFIED"

    designation and trademark.

    Wi-Fi has had a checkered security history. Its earliest encryption system, WEP, proved easy

    to break. Much higher quality protocols, WPA and WPA2, were added later. However, an

    optional feature added in 2007, called Wi-Fi Protected Setup (WPS), has a flaw that allows a

    remote attacker to recover the router's WPA or WPA2 password in a few hours on most

    implementations.[1]Some manufacturers have recommended turning off the WPS feature. The

    Wi-Fi Alliance has since updated its test plan and certification program to ensure all newly-

    certified devices resist brute-force AP PIN attacks.

    HISTORY

    802.11 technology has its origins in a 1985 ruling by the US Federal Communications

    Commission that released the ISM band for unlicensed use. In 1991 NCR

    Corporation with AT&T invented the precursor to 802.11 intended for use in cashier systems.

    The first wireless products were under the name WaveLAN.

    Vic Hayes has been called the "father of Wi-Fi". He was involved in designing the initial

    standards within the IEEE.

    In 1992 and 1996, Australian organisation the CSIRO obtained patents for a method later

    used in Wi-Fi to "unsmear" the signal. In April 2009, 14 tech companies agreed to pay

    CSIRO for infringements on the CSIRO patents. This lead to WiFi being attributed as

    anAustralian invention.

    In 1999, the Wi-Fi Alliance was formed as a trade association to hold the Wi-Fi trademark

    under which most products are sold.

    USES

    To connect to a Wi-Fi LAN, a computer has to be equipped with a wireless network interface

    controller. The combination of computer and interface controller is called a station. All

    stations share a single radio frequency communication channel. Transmissions on this

    channel are received by all stations within range. The hardware does not signal the user that

    the transmission was delivered and is therefore called abest-effort delivery mechanism. A

    carrier wave is used to transmit the data in packets, referred to as "Ethernet frames". Each

    station is constantly tuned in on the radio frequency communication channel to pick up

    available transmissions.

    1) Internet access

    A Wi-Fi-enabled device can connect to the Internet when within range of a wireless

    networkconnected to the Internet. The coverage of one or more (interconnected) access

    pointscalled hotspotscomprises an area as small as a few rooms or as large as many

    square miles. Coverage in the larger area may depend on a group of access points with

    overlapping coverage. Outdoor public Wi-Fi technology has been used successfully

    in wireless mesh networks in London, UK.

    Wi-Fi provides service in private homes, high street chains and independent businesses, as

    well as in public spaces at Wi-Fi hotspots set up either free-of-charge or commercially.Organizations andbusinesses, such as airports, hotels, and restaurants, often provide free-use

    hotspots to attract customers. Enthusiasts or authorities who wish to provide services or even

    to promote business in selected areas sometimes provide free Wi-Fi access.

    Routers that incorporate a digital subscriber line modem or a cable modem and a Wi-Fi

    access point, often set up in homes and other buildings, provide Internet access

    and internetworking to all devices tuned into them, wirelessly or via cable. With the

    emergence ofMiFi andWiBro (a portable Wi-Fi router) people can easily create their own

    Wi-Fi hotspots that connect to Internet via cellular networks.Now Android,Bada,iOS (iPhone), and Symbian devices can create wireless connections.

    One can also connect Wi-Fi devices in ad-hoc mode for client-to-client connections without a

    router. Wi-Fi also connects places that normally don't have network access, such as kitchens

    and garden sheds.

    2) City-wide Wi-FiIn the early 2000s, many cities around the world announced plans to construct city-wide Wi-

    Fi networks. There are many successful examples; in 2005 Sunnyvale, California, became the

    first city in the United States to offer city-wide free Wi-Fi, ] and Minneapolis has generated

    $1.2 million in profit annually forits provider.

    In 2004, Mysore became India's first Wi-fi-enabled city and second in the world after

    Jerusalem. A company called WiFiyNet has set up hotspots in Mysore, covering the complete

    city and a few nearby villages.

    In May 2010, London, UK, Mayor Boris Johnson pledged to have London-wide Wi-Fi by

    2012. Several boroughs including Westminster and Islington already have extensive outdoor

    Wi-Fi coverage.

    3) Campus-wide Wi-Fi

    Many traditional college campuses provide at least partial wireless Wi-Fi Internet

    coverage. Carnegie Mellon University built the first campus-wide wireless Internet network,

    called Wireless Andrew at its Pittsburgh campus in 1993 before Wi-Fi branding originated.

    In 2000, Drexel University in Philadelphia became the United States's first major university

    to offer completely wireless Internet access across its entire campus.

    4) Direct computer-to-computer communications

    Wi-Fi also allows communications directly from one computer to another without an access

    point intermediary. This is calledad hoc Wi-Fi transmission. This wireless ad hoc

    networkmode has proven popular with multiplayerhandheld game consoles, such as

    theNintendo DS,digital cameras, and otherconsumer electronics devices.

    Similarly, the Wi-Fi Alliance promotes a specification called Wi-Fi Directfor file transfers

    and media sharing through a new discovery- and security-methodology. Wi-Fi Direct

    launched in October 2010.

    Some devices can also share their Internet connection using ad-hoc, becoming hotspots or

    "virtual routers".

    The popularity of wireless LANs is a due to their convenience, cost efficiency, and ease of

    integration with other networks and network components. The majority of computers sold to

    consumers today come pre-equipped with all necessary wireless LAN technology.

    Convenience The wireless nature of such networks allows users to access network

    resources from nearly any convenient location within their primary networking environment(a home or office). With the increasing saturation of laptop-style computers, this is

    particularly relevant.

    Mobility With the emergence of public wireless networks, users can access the internet

    even outside their normal work environment. Most chain coffee shops, for example, offer

    their customers a wireless connection to the internet at little or no cost.

    Productivity Users connected to a wireless network can maintain a nearly constant

    affiliation with their desired network as they move from place to place. For a business, this

    implies that an employee can potentially be more productive as his or her work can beaccomplished from any convenient location.

    Deployment Initial setup of an infrastructure-based wireless network requires little more

    than a single access point. Wired networks, on the other hand, have the additional cost and

    complexity of actual physical cables being run to numerous locations (which can even be

    impossible for hard-to-reach locations within a building).

    Expandability Wireless networks can serve a suddenly-increased number of clients with

    the existing equipment. In a wired network, additional clients would require additional

    wiring.

    Cost Wireless networking hardware is at worst a modest increase from wired counterparts.

    This potentially increased cost is almost always more than outweighed by the savings in cost

    and labor associated to running physical cables.

    Disadvantages

    9/15

    For a given networking situation, wireless LANs may not be desirable for a number of

    reasons. Most of these have to do with the inherent limitations of the technology.

    Security To combat this consideration, wireless networks may choose to utilize some of the

    various encryption technologies available. Some of the more commonly utilized encryption

    methods, however, are known to have weaknesses that a dedicated adversary cancompromise.

    Range The typical range of a common 802.11g network with standard equipment is on the

    order of tens of meters. While sufficient for a typical home, it will be insufficient in a larger

    structure. To obtain additional range, repeaters or additional access points will have to be

    purchased. Costs for these items can add up quickly.

    Reliability Like any radio frequency transmission, wireless networking signals are subject

    to a wide variety of interference, as well as complex propagation effects that are beyond the

    control of the network administrator.

    Speed The speed on most wireless networks (typically 1-54 Mbps) is far slower than even

    the slowest common wired networks (100Mbps up to several Gbps). However, in specialized

    environments, wired network might be necessary.

    BLUETOOTH

    Bluetooth is a proprietaryopen wireless technology standard for exchanging data over short

    distances from fixed and mobile devices, creatingpersonal area networks (PANs) with high

    levels of security. Created by telecoms vendorEricsson in 1994, it was originally conceived

    as a wireless alternative to RS-232data cables. It can connect several devices, overcoming

    problems of synchronization.

    Bluetooth is managed by the Bluetooth Special Interest Group (SIG), which has more than

    15,000 member companies in the areas of telecommunication, computing, networking, and

    consumer electronics. The SIG oversees the development of the specification, manages the

    qualification program, and protects the trademarks. To be marketed as a Bluetooth device, it

    must be qualified to standards defined by the SIG. A network of patents is required to

    implement the technologyand are only licensed to those qualifying devices; thus the protocol,

    whilst open, may be regarded as proprietary

    Bluetooth Technology Over the Years

    1998 - Bluetooth technology is officially introduced and the Bluetooth SIG is formed.

    Bluetooth technology's intended basic purpose is to be a wire replacement technology in

    order to rapidly transfer voice and data.

    1999 - Bluetooth 1.0 Specification is introduced.

    2003 - The Bluetooth SIG overhauls the Bluetooth Core Specification with the announcement

    of Version 2.1.

    2004 - Bluetooth Version 2.0 + EDR (Enhanced Data Rate) is introduced.

    2005 - Devices using Version 2.0 + EDR begin to hit the market in late 2005.

    2007 - Bluetooth Core Specification Version 2.1 + EDR is adopted by the Bluetooth SIG.

    2009 - Bluetooth Core Specification Version 3.0 + HS (High Speed) is adopted by the

    Bluetooth SIG.

    Dial-up internet access on personal computers or PDAs using a data-capable mobile

    phone as a wireless modem.

    Short range transmission of health sensor data from medical devices to mobile

    phone, set-top box or dedicated telehealth devices. Allowing a DECT phone to ring and answer calls on behalf of a nearby cell phone

    Real-time location systems (RTLS), are used to track and identify the location of objects

    in real-time using Nodes or tags attached to, or embedded in the objects tracked, and

    Readers that receive and process the wireless signals from these tags to determine their

    locations

    Personal security application on mobile phones for prevention of theft or loss of items.

    The protected item has a Bluetooth marker (e.g. a tag) that is in constant communication

    with the phone. If the connection is broken (the marker is out of range of the phone) then

    an alarm is raised. This can also be used as a man overboard alarm. A product using this

    technology has been available since 2009.

    Advantages & Disadvantages of Bluetooth

    While using the Bluetooth feature, you can run through a lot of advantages to and at the same

    time and run to a lot of disadvantages also. With about every great technology, there has to be

    something in there that makes it not perfect. There's probably no such thing of a perfect

    product. A few advantages and disadvantages of Bluetooth includes the following.

    Advantages:

    Widely Used: Bluetooth is now really popular and keeps getting more popular as time passes

    by. It is now widely used across countries and almost by everyone. Companies are taking the

    benefit by using this in their new and future products to make life much easier for everyone.

    Pretty much very soon, you will be noticing quite a bit of technology will be wireless due to

    Bluetooth. As it is already, but most likely it will be more dominant. You can use Bluetooth

    on laptops, cell phones, music players, headsets, printers and a lot more other products.

    Feature Simplicity: You do not need to know much about technology in order to run

    Bluetooth. Anyone that doesn't have no knowledge about the new technology can still be able

    to use the Bluetooth feature due to its simplicity and the ease of use. I think that the

    simplicity of it and the fact that it's wire free makes it very widely used and utmost popular.

    Free of Charge: Best of all, you do not have to pay a penny for the service! It's not an extra

    cell phone or cable bill that you have to add to your budget. Simply by the technology and

    you're done! All you need to do is connect it with what you are using. There hasn't been any

    reporting lately on companies charging a monthly fee or any fee for people to use the

    Bluetooth feature and I don't expect it.

    Go Wireless!: It allows you to stay cord free and do not have to worry about finding the

    correct place to connect that extra long cord. Avoid having to have a ton of cords wherever

    you go. You may still need a few cords but not as much as you would without Bluetooth.

    You can also go to the internet wirelessly with this feature when you're out somewhereoutside of yourhome.

    Your in Control: Even though you are able to exchange data across your cell phones, you

    still have the ability to keep your information private. In order to make a transfer or allow

    someone to access the files on your phone, you will have to give them access by accepting or

    rejecting the request through your phone. If you have the Bluetooth feature enabled on your

    phone and not disabled while using it, others that you may not even know request to send you

    a file.

    Disadvantages:

    Battery Use: This occurs mostly on your cell phone but also occurs in other technology such

    as music players. You're using up more battery power when you leave your Bluetooth

    enabled on your phone all day. To disregard all this, the best thing that you can possibly do is

    disable it once you are completed with the transfer. It only takes a few seconds to enable and

    disable so it wouldn't hurt to disable it once you are done using it.

    Bluetooth Internet: Throughout all devices, when using Bluetooth internet, the connection

    can sometimes run very slow so Bluetooth internet is not highly suggested for all cases.

    As you can notice that there are quite a bit of advantages and fewer disadvantages. Overall,

    Bluetooth is a great thing to be using on all your devices that supports it. You can do so much

    with it and includes cutting all the cords attached to your devices.

    Bluetooth vs. Wi-Fi (IEEE 802.11)

    Bluetooth and Wi-Fi (the brand name for products using IEEE 802.11 standards) have some

    similar applications: setting up networks, printing, or transferring files. Wi-Fi is intended as a

    replacement for cabling for general local area networkaccess in work areas. This category of

    applications is sometimes called wireless local area networks (WLAN). Bluetooth was

    intended for portable equipment and its applications. The category of applications is outlined

    as the wirelesspersonal area network(WPAN). Bluetooth is a replacement for cabling in a

    variety of personally carried applications in any setting and can also support fixed location

    applications such as smart energy functionality in the home (thermostats, etc.).

    Wi-Fi is a wireless version of a common wired Ethernet network, and requires configurationto set up shared resources, transmit files, and to set up audio links (for example, headsets and

    hands-free devices). Wi-Fi uses the same radio frequencies as Bluetooth, but with higher

    power, resulting in higher bit rates and better range from the base station. The nearest

    equivalents in Bluetooth are the DUN profile, which allows devices to act as modem

    interfaces, and the PAN profile, which allows for ad-hoc networking
