Wireless trends

Wireless communication Wireless communicationis thetransfer of informationorpowerbetween two or more points that are not connected by an electrical conductor. The most common wireless technologies useradio. With radio waves distances can be short, such as a few meters fortelevisionor as far as thousands or even millions of kilometers for deep-space radio communications. It encompasses various types of fixed, mobile, and portable applications, includingtwo-way radios,cellular telephones,personal digital assistants(PDAs), andwireless networking. Other examples of applications of radiowireless technology includeGPSunits,garage door openers, wirelesscomputer mice,keyboardsandheadsets,headphones,radio receivers,satellite television,broadcast televisionandcordless telephones.Wireless operations permit services, such as long-range communications, that are impossible or impractical to implement with the use of wires. The term is commonly used in thetelecommunicationsindustry to refer to telecommunications systems (e.g. radio transmitters and receivers, remote controls, etc.) which use some form of energy (e.g.radio waves, acoustic energy,) to transfer information without the use of wires.

Wireless Trends Understanding wireless technology trends will allow you to position yourself and ride the coming wave of change... the tide is already rising.One trend is very clear...Its the overall rapid growth of wireless technology itself, driven by demand and innovation, as it changes our lives in all sorts of useful ways.

Applications may involvepoint-to-point communication,point-to-multipoint communication,broadcasting,cellular networksand otherwireless networks, Wi-Fi technology

Phones..Asmartphoneis amobile phonewith an advancedmobile operating systemwhich combines features of apersonal computer operating system with other features useful for mobile or handheld use.Smartphones, which are usually pocket-sized, typically combine the features of acell phone, such as the abilities to place and receive voice calls and create and receivetext messages, with those of other popular digitalmobile deviceslikepersonal digital assistants(PDAs), such as an event calendar,media player,video games,GPS navigation,digital cameraanddigital video camera. Most smartphones can access theInternetand can run a variety ofthird-party software components("apps"). They typically have a colordisplaywith agraphical user interfacethat covers 70% or more of the front surface. The display is often atouchscreen, which enables the user to use avirtual keyboardto type words and numbers and press onscreen icons to activate "app" features.It is a camera, phone, mp3, workplace, everything in pocket.It is one of the major reforms in wireless technology

Bluetooth ConnectivityOne of the most common connectivity options

Bluetooth technology is the global wireless standard enabling the Internet of Things (IoT).Created in 1994,Bluetoothtechnology was conceived as a wireless alternative to data cables by exchanging data using radio transmissions. The name Bluetooth came from a tenth century Danish King, Harald Bltand or, in English, Harold Bluetooth. As the story goes, King Bltand helped unite warring factions in parts of what are now Norway, Sweden and Denmark. Similarly, Bluetooth technology was created as an open standard to allow connectivity and collaboration between disparate products and industries.Bluetooth allows high quality streamingOne of the most popular applications for Bluetooth historically has been wireless audioheadsets and hands-free connectivity in cars to wireless speakers and headphones that stream music from your phone or tablet. This uses a version of Bluetooth calledBR/EDR(bit rate/enhanced data rate) that is optimized for sending a steady stream of high quality data (i.e. music) in a power efficient way.

Wireless Services

Common examples of wireless equipment include:Infrared and ultrasonic remote control devicesProfessional LMR (Land Mobile Radio) and SMR (SpecializedMobile Radio) typically used by business, industrial and Public Safety entities.ConsumerTwo-way radioincluding FRSFamily Radio Service, GMRS (General Mobile Radio Service) and Citizens band ("CB") radios.TheAmateur RadioService (Ham radio).Consumer and professionalMarine VHF radios.Airbandandradio navigationequipment used byaviatorsandair traffic controlCellular telephonesand 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 earthCordless computer peripherals: the cordless mouse is a common example; wireless headphones, keyboards, and printers can also be linked to a computer via wireless using technology such asWireless USBorBluetoothCordless telephonesets: these are limited-range devices, not to be confused with cell phones.

Satellite television: Is broadcast from satellites ingeostationary orbit. Typical services usedirect broadcast satelliteto provide multipletelevisionchannels to viewers.

Ways to get wireless access to the Internet

There are three main ways you can get wireless access to the Internet...Local WiFi NetworkWide Area Cellular networkGlobal Area Satellite networkLet's look at each of these in more detail...

WLANs are often used to establish wireless Internet access points. But as the name suggests, they usually provide local short-range connections and are typically intended for use within (though not constrained by) a building.So while there are lots of WiFi networks around, many in public places and easy to access, you really cant move very far and expect to get continuous coverage. With Wi-Fi its more a case of wireless Internet 'in some places rather than anywhere.If you do use public WiFi, be aware that you may be working on an unsecured network that could expose your computer and information to online risks. However there are ways to minimize these risks.f you want Internet access, but dont need to move around much, public WiFi hotspots may be anywhere enough for you. However, if you are more mobile, and want to access the Internet even when you arent within Wi-Fi coverage, it may not be enough. Maybe you want continuous Internet when you are moving, in a train or a car...

Wireless Local Area network (WLAN)

Wi Fi ConnectivityToday found everywhereConvenience The wireless nature of such networks allow 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 be accomplished 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.

Mobile Hotspot.

Ahotspotis a physical location where people may obtainInternet access, typically usingWi-Fitechnology, via awireless local area network(WLAN) using arouterconnected to aninternet service provider.Public hotspots may be found in a number of businesses for use of customers in many developed urban areas throughout the world, such ascoffee shops. Many hotels offer wifi access to guests, either in guest rooms or in the lobby. Hotspots differ fromwireless access points, which are the hardware devices used to provide a wireless network service. Private hotspots allow Internet access to a device (such as a tablet) via another device which may have data access via say a mobile device.The public can use alaptopor other suitable portable device to access the wireless connection (usuallyWi-Fi) provided. Of the estimated 150 million laptops, 14 millionPDAs, and other emerging Wi-Fi devices sold per year for the last few years, most include the Wi-Fi feature.For venues that havebroadband Internet access, offering wireless access is as simple as configuring oneaccess point(AP), in conjunction with a router and connecting the AP to the Internet connection. A single wireless router combining these functions may suffice.

Wireless Gaming..Today gaming has gone wireless. Wireless gaming consoles, keyboard, mouse are easily available at an affordable price. One can also work by just sitting relaxed back on his/her computer. It has brought reforms in day to day life. It has helped people to get rid of the wires limitation but can sit and relax..Amotion controllercontrols the motionof some object. Frequently motion controllers areimplementedusing digitalcomputers, but motion controllers can also be implemented with onlyanalogcomponents as well. Motion controllers are used to achieve some desired benefit(s) which can include:increased position and speedaccuracyhigher speedsfasterreaction timeincreasedproductionsmoother movementsreduction in costsintegrationwith otherautomationintegration with other processesability to convert desired specifications into motion required to produce a productincreased information and ability diagnose andtroubleshootincreased consistencyimproved efficiencyelimination of hazards to humans or animals

Wireless power transfer!!!!Wireless power transfer(WPT) orwireless energy transmissionis the transmission ofelectrical energyfrom apower source Wireless power is a generic term that refers to a number of different power transmission technologies that use time-varyingelectric,magnetic, orelectromagnetic fields. In wireless power transfer, a wireless transmitter connected to a power source conveys the field energy across an intervening space to one or more receivers, where it is converted back to an electrical current and then used. Wireless transmission is useful to power electrical devices in cases where interconnectingwiresare inconvenient, hazardous, or are not possible. Innon-radiativetechniques, power is typically transferred bymagnetic fieldsusinginductive couplingbetweencoils of wire. Applications of this type includeelectric toothbrushchargers,RFIDtags,smartcards, and chargers for implantable medical devices likeartificial cardiac pacemakers, and inductive powering or charging ofelectric vehicleslike trains or buses. A current focus is to develop wireless systems to charge mobile and handheld computing devices such ascellphones,digital music playersand portable computers without being tethered to a wall plug.

Wireless Printing.HP ePrint via Email is a feature of mostHPprinters and MFPs that enables printing documents attached to email messages sent to the device. The HP ePrint-capable printer or MFP must be registered to an HP ePrint cloud service calledHP ePrint Center, which assigns a uniqueemail addressto the printer or MFP. The assigned email address is customizable but by default is arbitrarily set to promote security since only those who know the email address can use it to print. HP ePrint via Email does not require aprint driverinstalled on the client. The HP ePrint public cloud renders the printing data from each separate attachment into a suitable print data stream, such as PCL3,PCL 5, orPostScript, and, subsequently, sends it to the HP ePrint enabled printer. For this to work, the attachments for printing must be in a native plain format, such as any of the following:MS Word documentMS PowerPoint presentationMS Outlook documentImage file (JPEG,BMP,GIF,PNG,TIFF)Adobe Acrobat file (PDFs)Text file andRich Text Format(RTF)HTMLfile
