wifi

what is the range of that module ??

its manufacturer say's
The LR Receiver is ideal for the wireless transfer of serial data, control, or command information in the favorable 260-470MHz band. The receiver’s advanced synthesized superhet architecture achieves an outstanding typical sensitivity of -116dBm, which provides a 5-10 times improvement in range over previous solutions. When paired with a compatible Linx transmitter, a reliable wireless link is formed, capable of transferring data at rates of up to 10,000bps at distances in excess of 3,000 feet. Applications operating at short distances, or lower data rates will also benefit from increased link reliability and superior noise immunity.

nope the rf is very expensive here in egypt and there is many restrictions to use it and to get it from outside egypt so it can take a long time and i need it urgently
and you can tell me how to use the rf as well to gain some knowledge thank you all

hi osamamongy
ok then think on wifi module and choose it urgently
visit ur market which one is available
rf is simple and its interfacing vary from module to module normally all serial interfaced with controller or encoders

ooh thanks this is much helping but i do not know much about the wifi communication so what material is you advice me with also i need a c source code example tor this because i'm not aware much with c but um good at assembly and i think it's more exahostive to write it in assemby so if you have an example it would be very helpful to me
and thank you very much for helping

hi osamamongy
go through from this thread

visit a spark fun site that has many this type of things
Wiznet WIZ610wi has a UART serial interface so easy to interface with any controller having UART
visit these sites

code is second task because first u has module then code according to its interface
module depend on ur pocket ur sources etc
its better u visit spark fun to decide which is fit for u
any module having UART or I2C interface thats easy to use

Hi Osamamongy
