The Ubiquiti Rocket M900 would be a good place to start.

Or if you have a couple old Ricochet E-radios and want to do some packet hacking, they'll do 1Mbaud at whatever modulation you ask.

I work with industrial grade 900MHz radios, and most can do over 1Mbps... with enough SNR, which as I mentioned can be difficult. I would say a typical ~city sized network I've worked on tend to operate in 100-1000kbps modes, with real world throughputs maxing out at more like 300-400 kbps on typically 1-10 mile links.

Manufacturers include FreeWave, GE MDS, XetaWave, 4RF, and others. These are typically ~$1000 radios, so not great for hobbyist use.

Yeah I’d be very happy to be pointed in the direction of a multiple megabit per second 900 radio. Take my money!

In addition to Ubiquiti (already mentioned), Motorola (Cambium) also made some PTP and PTMP radios ("Canopy"?) that were quite popular in the WISP community years ago.

I'd be surprised if you can't easily find both on eBay.
