Is there a restriction on OFDM bandwidth for a determined symbol time?

Hi,

If a frequency bin width is determined, then the symbol time is known. 
How many bins are acceptable, i.e. is there a restriction on the bandwidth 
of the OFDM symbol?


Thanks,

Adding subcarriers increases N, the FFT size.   As long as you can
keep up with the processing and have the channel bandwidth available
there's nothing stopping you from adding more subcarriers.
