There's the DVB-T transmitter and receiver in the Digital Television
component of GNU Radio. It's capable of 31.6 Mbps in a standard 8 MHz
bandwidth. (and can be used at higher bandwidths).
I have some OOT modules that allow sending IP packets over DVB. Note
that these modules only implement the transmit portion and are meant to
be used with commercial receivers.

One of the drawbacks is that DVB-T is a streaming protocol, so a two-way
link would require a full-duplex RF system. Also, latency is pretty high
due to the long frame size used in DVB-T. You can get a much lower
latency with the DVB-T2 transmitter (which has adjustable frame size),
but there's no companion DVB-T2 receiver in GNU Radio (you have to use a
commercial DVB-T2 receiver like the PCTV 292e).

Hi,
For OFDM transmitter and receiver, I was using benchmark_tx/rx
implementations. However, I am wondering what is the best publicly
available OFDM implementation for relatively high bandwidths (10s of
MHz) and data rates (10s of Mbps)?
Best,
Sinan
