data rates rf
hi all ,
i want to make a project in which a video and some data should be transmitted to another unit in a far distance ... , i want to invert Video signal to digital or use digital webcams and then send them as data through a wirless data tranceiver , i searche ATMEL webstie and found some IC's for this application , now i have some questions :
i want to amplify RF output to get a distance about 10 Km , which frequency is better to be used ? 315 / 345 / 433 / 868 / 915 Mh or 2.4 Gh ?
and do you know a RF amplifire circuit good for this application ?
i think more than 100Kbps be a good datarate for this application , if you know other IC's for this application , plz say ...
and is it possible that i use a long range cordless phone , then make a FSK modulator and demodulator , then connect them to input and output of may cordless phone to make a long range data tranceiver ?
how should i calculate the maximume frequency of FSK that would be connected to input of cordless phone ? ( RF modulation is FM )
Thanks & Best regards.
