Wireless network refers to any type of computer network that is wireless, and is commonly associated with a telecommunications network whose interconnections between nodes are implemented without the use of wires.[1] Wireless telecommunications networks are generally implemented with some type of remote information transmission system that uses electromagnetic waves, such as radio waves, for the carrier and this implementation usually takes place at the physical level or "layer" of the network.

A wireless local area network (WLAN) links two or more devices using some wireless distribution method (typically spread-spectrum or OFDM radio), and usually providing a connection through an access point to the wider internet. This gives users the mobility to move around within a local coverage area and still be connected to the network

Wireless technology has evolved. At first, the goal was to expedite the communications between humans. Now, however, the new wave  of wireless technology focuses on machine-to-machine(M2M) interactions. "The M2M phenomenon is part of the larger drive to create an "Internet of Things" - a global network that not only links computers, tablets and phones but that connects everything from bikes to washing machines to thermostats. Machina Research, a British firm, believes there will be 12.5 billion "smart" connected devices, excluding  phones, PCs and tablets, in the world in 2020, up from 1.3 billion today."

"Wireless operations permits services, such as long range communications, that are impossible or impractical to implement with the use of wires."

"One of the best-known examples of wireless technology is the mobile phone"

This is article has some good information on what is wireless connection!

I enjoyed reading this article it has some good information on what is wireless connection and communication and how it works!

Wireless Connections Keep Increasing 3/21/2012 Connected devices are growing at a fast pace, and the increasing number of mobile devices is adding to the number of worldwide wireless connections. Soon, there may be nearly as many connections as people on the planet. The day when there is a wireless connection for every person is coming soon.

Commotion Wireless offers a new interface for wireless connectivity that does not require and Internet Service Provider(ISP). This is useful to circumnavigate Internet restrictions and to enable mobile phones a greater degree of freedom. To work this technology only requires to WiFi capable devices. Thus, this technology can be readily used by a population that does not possess access to the Internet to share files, media, and other documents to collaborate.

This site shows how wireless connectivity is popping up in colleges around the world.

"Mobile technology is exactly what the name implies - technology that is portable. Examples of mobile IT devices include: laptop and netbook computers palmtop computers or personal digital assistants mobile phones and 'smart phones' global positioning system (GPS) devices wireless debit/credit card payment terminals Mobile devices can be enabled to use a variety of communications technologies such as: wireless fidelity (Wi-Fi) - a type of wireless local area network technology Bluetooth - connects mobile devices wirelessly 'third generation' (3G), global system for mobile communications (GSM) and general packet radio service (GPRS) data services - data networking services for mobile phones dial-up services - data networking services using modems and telephone lines virtual private networks - secure access to a private network It is therefore possible to network the mobile device to a home office or the internet while travelling. Benefits Mobile computing can improve the service you offer your customers. For example, when meeting with customers you could access your customer relationship management system - over the internet - allowing you to update customer details whilst away from the office. Alternatively, you can enable customers to pay for services or goods without having to go to the till. For example, by using a wireless payment terminal diners can pay for their meal without leaving their table. More powerful solutions can link you directly into the office network while working off site, for instance to access your database or accounting systems. For example, you could: set up a new customer's account check prices and stock availability place an order online This leads to great flexibility in working - for example, enabling home working, or working while travelling. Increasingly, networking 'hot spots' are being provided in public areas that allow connection back to the office network or the internet.

Wireless Connectivity Overview Article

Wireless growth and usage show no signs of slowing as more Americans are increasingly using mobile to connect. In 2011 alone, wireless data traffic grew 133%, and with more wireless subscriptions than people in the U.S.

"Going wireless generally requires connecting an internet "access point""

Wired or wireless Connecting your devices to a home network is really easy. You can use a wired network, a wireless network or, if you're using more than one device, a combination of the two.

"A personal digital assistant (PDA), also known as a palmtop computer,[1][2] is a mobile device that functions as a personal information manager. Current PDAs often have the ability to connect to the Internet. A PDA has an electronic visual display, enabling it to include a web browser, but some newer models also have audio capabilities, enabling them to be used as mobile phones or portable media players. Many PDAs can access the Internet, intranets or extranets via Wi-Fi or Wireless Wide Area Networks. Many PDAs employ touchscreen technology. The term PDA was first used on January 7, 1992 by Apple Computer CEO John Sculley at the Consumer Electronics Show in Las Vegas, Nevada, referring to the Apple Newton. In 1996, Nokia introduced the first mobile phone with full PDA functionality, the 9000 Communicator, which grew to become the world's best-selling PDA. The Communicator spawned a new category of mobile phones: the smartphone. Today, the vast majority of all PDAs are smartphones. Over 150 million smartphones are sold each year, while "stand-alone" PDAs without phone functionality sell only about 3 million units per year.[specify] Popular smartphone brands include HTC, Apple, Palm, Nokia N-Series, and RIM BlackBerry."
