About mobile wireless access-driven development

            


This is my graduation design topic, I did not make the embedded program or even know nothing about it. Subject of the request, then Linux platform to do a cell phone drivers, so the phone can be used in the base station via a laptop unlimited Internet access instead of GPRS. Tutor just a brief introduction about the process: the development of a program on the phone, connected via wifi UART or RS232, and then connect via wifi wlan, wifi is in the market to buy. I do not understand, ah, dare to please understand the development of embedded or mobile phone a friend recommended to me some of the books, it is best to give some help for me this topic. Thank you.

Let the phone through a laptop with unlimited internet station without GPRS.
----------------
This function has applications in reality it?

Usually when the terminal while the phone when the laptop modem, in turn, no one really tried

Graduation topic, do first come out to say, not so much

Is wifi, but also as a graduation project? - Unlimited LAN.
The new models of mobile phones a lot of support, but it is relatively less mobile linux, windows mobile phone number 5.

Notebooks with unlimited base - so the teacher can teach it? It should be called a wireless router.
There are "connected to wifi via UART or RS232, and then connect via wlan wifi"

It seems, as long as the reason is clear these concepts, you will be able to successfully graduate.

To make a come on the market and sometimes they do, I will do it

If the phone is its own development, it is easy to pull.
You can write and pc communication procedures are easy to implement.

Other situations may not be easy.

You say in the market to buy the wifi is what?

Listen seem complicated, in fact, not difficult to give you a rough idea:
1, mobile phone focused directional data-carrying channels. If you are familiar with the mobile phone platform, then this should be relatively easy. Even on the phone linux platform little research, brew platform is relatively easy to implement, linux should be easier to implement, even feel, huh.
2, the transfer to the PC side via the serial port (or USB, Bluetooth, etc.) data. This is also very easy, basically a mobile phone now have such a feature.
3, PC-side reading serial data, restore the original data, and then through a PC network (finite or wireless are the same, are calling the corresponding interface) you can transfer the data out.
4, the data obtained from the PC side to reverse return.

Said study this truth has no commercial value, and last year's crash on the realization of, or bi-directional parallel transmission, ie PC, while the use of mobile Internet, the phone can also use the PC Internet.
If interested, you can do something difficult, when you were doing this, I feel more difficult it is to use a channel (a virtual serial port) to achieve concurrent processing bidirectional data, when non-equilibrium sharing process, but the effect is not good, efficiency and mass balance is difficult, very difficult to reach commercial purposes, and later had another virtual channel (to add a virtual serial port) to complete the two-way concurrent processing, namely A channel for processing the Mobile Internet PC, B channels for processing PC use mobile Internet .
If you can solve using a channel parallel processing is still very good, huh, huh.
