Yup, we have 56k here in San Diego on 70cm, been up for several years 25 miles point-to-point. Some folks up North are using 802.11b 6-7 miles at 6~7 Mbit.

The WA4DSY modem will do 56 kbps (http://www.paccomm.com). It operates at 29 MHz and must be used with a transverter for the appropriate band. Some hams in Slovenia have designed high speed equipment, see http://hamradio.si/hid.html for some links. On Sun, Aug 24, 2003 at 04:56:49PM -0700, A Gilmore wrote:
Having always had high-speed internet available, I have never looked into radio technology before. However, I have been asked recently if providing internet to a number of locations (varying between 10-50km away from central computer lab) is possible. Neither dial-up or broadband is accessible in these locations. So I started looking into radio. I will have one LAN with broadband internet, and remote LANs without any internet access. The idea is to put a TNC equipped linux gateway at each remote location, to tunnel TCP/IP over AX.25 to the central LAN with broadband, and route the TCP/IP from there. Is this feasible? Can speed be in the 28kbps or better range? Generally how much would the radio equipment cost? Is providing transparent internet by these means difficult, regarding routing and interfacing the protocols? Sorry if these questions are vague or overly simple, Id just like to know if this is possible before I spend the next several days researching it. Most of the information I have found so far, has been out-dated, and mostly focused on using TCP/IP to carry AX.25, rather then the vice-versa.
