Hello everyone. I see there has been some talk here about packet radio. I
think packet radio is highly overrated due to the extremely limited speed.
What I'd love to see is some kind of digital radio link with channel speeds of 256-512+ kbaud, with at least 16-32 channels available. Is there something out there like this already? Maybe using the 900 mhz spectrum or even SHF over 1 g? hz? Would anyone be willing to put in the time/resources to develop open
source hardware/software for this idea? I want it to be possible to set up a BBS over radio with high speed data transfers and message relaying between nodes in a mesh network, with full encryption. How can we make this happen?

There's 802.11af (available now), and 802.11ah (Coming very soon) which more or less fit what you describe. Is WiFi suitable, or did you want more of a multicast setup?

In terms of packet radio, it still holds interest as it is incredibly cheap to do in terms of computing and hardware required these days - You can now use a œ25 handheld radio and a computer of the same cost as a complete packet station hosting a BBS, Node and soft TNC functions. It might be slow, but it is cheap, simple and reliable.

There's something not dissimilar to what you're proposing using more or less off the shelf hardware on 2.4GHz - check out the FEEDNET[1] Project. They're doing long distance, multi-megabit communications in a mesh setup, with `internet class` services on the network - VoIP, audio/video streaming and others, alongside more traditional amateur radio hardware (analog voice repeaters and the like) all connected to the same network.
They've built on top of broadband-hamnet[2] concepts, but I'm less familiar with that.

BBS over radio with high speed data transfers and message relaying between nodes in a mesh network, with full encryption. How can we make this happen?

I'm unsure about other jurisdictions, but in the UK encryption is disallowed on amateur radio (section 11(2). There is an exception (when transmitting on behalf of a User Service) but the chances of that applying to a BBS and IP mesh network are slim. As such, this wouldn't be able to happen in the UK, however the meshnet is interesting at least!

Thank you gentlemen. I will do some reading up on feednet. I guess off the shelf 2.4 ghz wifi equipment could be used, though the hardware/firmware
would need to be modified to suit my purposes, at least to increase the radio power level. I don't think multicast is the right word; I'm thinking
something where a single station can transmit/receive data simultaneously
from multiple remote nodes, with TDMA multiplexing so that multiple nodes can also simultaneously access data on a single node/channel. Not sure what
scheme wifi 802.11 uses for channel access. Much research required.
