audioguru Posted November 30, 2005 Report Share Posted November 30, 2005 Data transmission using AM or FM transmitters?1) They will cause interference to radio reception and therefore are illegal.2) Their bandwidth is so narrow that you will be limited to maybe only 300 baud.Hi-speed Bluetooth and wireless routers are approved and are cheap. Get one and enjoy it. ;D Quote Link to comment Share on other sites More sharing options...
vinsu Posted September 10, 2006 Report Share Posted September 10, 2006 HI I belive it might be possible to tx data through FM band but the bandwidth might be very limited. If an ordinary telephone modem is connected to computer and that modem is interfaced with a transciever, considering all the problems of a possible oscillation of the whole thing due to feedback and couple of other things, a speed of upto 56kbps might be obtained.regardsvincent Quote Link to comment Share on other sites More sharing options...
audioguru Posted September 10, 2006 Report Share Posted September 10, 2006 A telephone line has a bandwidth of only 3kHz if you are lucky.A good FM transmitter and a stereo FM tuner has a bandwidth up to 53KHz, 17.7 times more bandwidth. It calculates to a data rate of nearly 1Mb/sec. Try it. Quote Link to comment Share on other sites More sharing options...
ante Posted September 11, 2006 Report Share Posted September 11, 2006 A telephone line has a bandwidth of only 3kHz if you are lucky.It depends on how you use the phone line; my Internet connection, which uses the phone line, can transfer 24Mb/s (ADSL)! This is enough to watch live TV transmission in full screen with stereo sound in HiFi! ;) Quote Link to comment Share on other sites More sharing options...
audioguru Posted September 11, 2006 Report Share Posted September 11, 2006 Hi Ante,If you are far from the telco's central office then the high capacitance of the telephone line cuts the high frequencies.My daughter's ADSL is only about 40kb/s which is better than 8kb/s from a 56k modem on the same phone line, but not nearly as fast as yours.I switched my high speed cable internet to "High Speed Lite". It costs half as much and the speed is about half of what it used to be but it is still pretty fast. Live TV stops then gets buffered frequently.

evr Posted September 16, 2006 Report Share Posted September 16, 2006 do you hear any data transmitter using fm wave. if, so pls reply with the web address. Quote Link to comment Share on other sites More sharing options...
audioguru Posted September 16, 2006 Report Share Posted September 16, 2006 A radio transmitter can be AM or FM modulated. Data can be DTMF, ways using a phase-shift and many other ways. My local FM stations transmit data so my car radio shows the name of a song, the singer and all kinds of information. Quote Link to comment Share on other sites More sharing options...
mugsby Posted October 27, 2006 Report Share Posted October 27, 2006 ethernet is balanced, you need to change that first. Quote Link to comment Share on other sites More sharing options...
