WAP

Wireless Application Protocol (commonly referred to as WAP) is an open international standard for application layer network communications in a wireless communication environment. Its main use is to enable access to the Internet (HTTP) from a mobile phone or PDA.
A WAP browser provides all of the basic services of a computer based web browser but simplified to operate within the restrictions of a mobile phone, such as its smaller view screen. WAP sites are websites written in, or dynamically converted to, WML (Wireless Markup Language) .

Some of the applications such as:
Email by mobile phone
Tracking of stock market prices Sports results
News headlines
Music downloads

NANOTECHNOLOGY

Nanotechnology, which is sometimes shortened to "Nanotech", refers to a field whose theme is the control of matter on an atomic and molecular scale. Generally nanotechnology deals with structures of the size 100 nanometers or smaller, and involves developing materials or devices within that size.
Nanotechnology is extremely diverse, ranging from novel extensions of conventional device physics, to completely new approaches based upon molecular self-assembly, to developing new materials with dimensions on the nanoscale.

Nanomaterials
Includes subfields which develop or study materials having unique properties arising from their nanoscale dimensions.
Interface and Colloid Science has given rise to many materials which may be useful in nanotechnology, such as carbon nanotubes and other fullerenes, and various nanoparticles and nanorods.
Nanoscale materials can also be used for bulk applications; most present commercial applications of nanotechnology are of this flavor.
Progress has been made in using these materials for medical applications; see Nanomedicine.

Submarine Navigation of Catamaran in the brim using Wireless technology

The peninsula,island and the coastal countries had their boundary limit in the sea, the people's lives in those types of country has the work of fishing in the sea due to carelessness or without knowing their boundary limit of their country they crossing the borders. In such situation the lives of fishermen continue to be difficult.If they faced bullets from the Enemy Navy lot they were killed, now they are at the receiving end of attacks by apposite navy.They are being abducted and their boats are being captured.
Nowadays people living in coastal areas are loss their valuable life unknowingly.Those peoples shot death by the neighborhood militants,saying that they crossing the borders.So our project is designed to avoid such kind of accidents and to alert the fisherman about the border areas.
In this project consists ot three modules Border area section,Dash Board Section in the Boat,Navy control section.In the Border area section the Border ID's, are placed in the sides of the border in the underwater section when the boat approaches the border means the information gives to the boat ,if they further proceed means the boat ID will transferred to the Navy control Room and alert the Boat Sections.

WIRELESS COMMUNICATION

Wireless communication is the transfer of information over a distance without the use of electrical conductors or "wires". The distances involved may be short (a few meters as in television remote control) or very long (thousands or even millions of kilometers for radio communications).

Wireless communication is generally considered to be a branch of telecommunications.
It encompasses various types of fixed, mobile, and portable two way radios, cellular telephones, personal digital assistants (PDAs), and wireless networking. Other examples of wireless technology include GPS units, garage door openers and or garage doors, wireless computer mice, keyboards and headsets, satellite television and cordless telephones.

Wireless communication may be via:
radio frequency communication,
microwave communication, for example long-range line-of-sight via highly directional antennas, or short-range communication, or
infrared (IR) short-range communication, for example from remote controls or via IRDA,
Applications may involve point-to-point communication, point-to-multipoint communication, broadcasting , cellular networks and other wireless networks
