Wireless Communication Possibilities greater than 1Mb/s

Angela Selden
Prodigy 20 points

Is it possible to get a wireless signal to transmit data faster than 1Mb/s using a micro controller? I am trying to transmit data wirelessly at a rate of about 1Mb/s before any required overhead. Any recommendations of what to use?

Ultimately I am trying to take in 4 analog signals, digitize them at 12 bits per sample and one 8-bit digital signal at a sampling rate of 20,000 times per second per channel and transmit the data wirelessly to another device. That means I need 1,120,000 bits per second before any overhead to be transmitted.

Any ideas of what to use to get me started in the right direction?

Thank you in advance for any help you can provide!

    Hello,

    In the RF/IF Low Power wireless forum there are Zigbee and RF devices.  There are several other topologies:

    a) using a TI DSP with McBSP, McASP you could digitize the analog data in a multi channel ADC.  The TI DSP would provide coding, timing and control.  The output of the 6713DSP - McBSP can go to a GC4116 digital up converter, DAC 5688, Quadrature Modulator.  This method supports bandwidths and coding upto several Mbits per second.  This is not a single EVM but several EVMs.

    b) using newer Wireless terminal chipset, the ADC and digital data would be the payload for several user channels

    c)  there are combinations of the TI DSP, with McBSP multi channel audio, to CMOS or LVDS uPP busses to integrated ADC and DAC devices. 

    I would start with the Low Power wireless forum to see if there is an integrated solution, they others listed require several EVMs.
