ABSTRACT
With the development of Internet, more and more quickly, and the popularization of mobile
phone, notebook computer, the user can access on demand whenever and wherever possible the
more urgent, the application of WiFi communication technology in mobile phone, computer
Internet is more and more widely, the development and application of WiFi is developed more and
more rapidly in real life.
WiFi is the abbreviation of Wireless Fidelity, also called 802.11b, is a IEEE definition of a
wireless network communication industry standards, is a personal computer, handheld devices
(such as PDA, mobile phone), terminal in wireless connection with each other, which can help users
to access e-mail, Web and streaming media. Its main characteristics are: speed, high reliability, long
communication distance. In an open area, communication distance up to 305 meters, in the closed
area, communication distance of 76 meters to 122 meters, in the family, office and travel on the
Internet convenience. Due to the characteristics of WiFi covering a wide range, fast speed, high
reliability, no wiring, health security and billing is cheap, has become the mainstream standard of
wireless internet access, as long as the electronic equipment to carry the integrated WiFi wireless
communication terminal users, WiFi can cover the area at any time to make or receive a call, fast
browsing webpage, download or upload audio and video files, e-mail, without having to worry
about the costs are too high and too slow speed etc.. At present, many of China's railway station,
airport, school, office area, bustling shopping malls, library, the well-known tourist attractions are
the WiFi signal coverage.
In view of the many advantages of ARM microprocessor, with the gradual development of the
embedded application field, the ARM microprocessor will receive widespread attention and
application. However, due to the ARM microprocessor core structure up to a dozen, dozens of chip
manufacturers, as well as the myriads of changes of the internal function combination, development
staff brought certain difficulty, in the selection of programmes so, on the ARM chip do some
comparative study is very necessary
Most of the advantages of WiFi Based on wireless technology research, we carried on portable
electronic product development mainstream chip under the framework of ARM WiFi, I use and
write the serial debugging tools, WiFi successfully applied to realize the data transmission between
the computer and the computer.
