Wireless is a term used to describe telecommunications where electromagnetic waves, instead of a physical wire, carry the signal over some, or all of the communication path.
WAP (Wireless Application Protocol) are communication protocols that standardize the way wireless devices, such as cell phones and radio transceivers, are used for Internet access, including e-mail, the Web, newsgroups, and instant messaging. While Internet access has been possible in the past, different manufacturers have used different technologies. In the future, devices and service systems that use WAP will be able to interoperate.
WAP layers are:
* Wireless Application Environment (WAE)
* Wireless Session Layer (WSL)
* Wireless Transport Layer Security (WTLS)
* Wireless Transport Layer (WTP)
The WAP was conceived by four companies: Ericsson, Motorola, Nokia, and Unwired Planet (now Phone.com). The Wireless Markup Language (WML) is used to create pages that can be delivered using WAP. Besides WAP, There are other industry standards, including i-Mode; the world's first "smart phone" for Web browsing, (providing color & Video) introduced first in Japan.
Wireless categories:
Fixed: wireless devices or systems in homes and offices, and in particular; equipment connected to the Internet via modems
Mobile: wireless devices or systems aboard moving vehicles;
Portable: autonomous, battery-powered wireless devices or systems outside the office, home, or vehicle; such as; handheld cell phones and PCS units
IR: devices that convey data via infrared radiation; employed in certain limited-range communications and control systems
History
The first wireless transmitters went on the air early in the 20th century using Morse code. Later, as modulation made it possible to transmit voices via wireless, the medium came to be called "radio." With the advent of television, fax, data communication, 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: Cell phones and pagers, Global Positioning System (GPS) Cordless computer peripherals, Cordless telephone sets, Home-entertainment-system control boxes, Remote garage-door openers, Two-way radios, Baby monitors, Satellite television, Wireless LANs or local area networks.
More specialized and exotic examples of wireless communications and control include:
• Global System for Mobile Communication (GSM) --the de facto wireless telephone standard in Europe
• General Packet Radio Service (GPRS) -- a packet-based wireless communication service that provides continuous connection to the Internet for mobile phone and computer users
• Enhanced Data GSM Environment (EDGE) -- a faster version of the Global System for Mobile (GSM) wireless service
• Universal Mobile Telecommunications System (UMTS) -- a broadband, packet-based system offering a consistent set of services to mobile computer and phone users no matter where they are located in the world.
