Hello!
To make a network between 2 sites in a MAN or WAN the posibilities
would be:
- cabling (leased lines, fiber optic)
- air waves (microwaves, ax25, packet...)
- any provider providing the link via cabling or airwaves or
satelite
Wavelan/Orinoco cards can make a link about 15km.
Which tecnologies are available to make a link of ~200 kilometers
with speed at least 64kbps?
AFAIK hf will give the distance in a single hop but not the bandwidth.VHF will require three hops. Several modems exist. CDPD services can provide the distance but BW may be limited http://www.sss-mag.com/pdf/1cdpd.pdf
