Wireless Networks in Metropolitan Areas? 12
Lomby asks: "I am networking a company that has two offices in the same city.
Clearly they would like to exchange data between them.
Since I live in an internet under-developed country (Switzerland), a
permanent cable connection is out of question due to the high costs.
The most obvious choice is to connect the two offices via ISDN, but this has the drawback of cost per time unit, and the connection would
be estabilished only a few time a day, bringing consistency problems. Now I'm looking at a wireless solution: has anyone tested a wireless system in a metropolitan area (10 km)? Costs? Problems? Field of view? Works with Linux? Do I need to install a huge antenna? "

Can the local phone company provde both locations the services ATM or DSL?

If you're a small company then ADSL may be your best option.
If you're a very small company or just some geeks putting together a network for kith and kin then a MultiLink PPP connections 56K dialup technology tandem/parallel modem bank like the Diamond products "http://209.10.46.176/default.asp?menu=suprasonic
I don't look at ISDN anymore as a communications solution
Why ATM, because with an ATM backbone access at bothe LANs, switched LANs/Routers/Hubs to an ATM backbone, and Ethernet infrastructure (cables/connectors/...) data delivery latency for even VTC may not be a major factor (eliminating ISDN drops/requirements).
Why ADSL, well depending on the local cable/phone company owners' policy (and government regulations) you could do an ADSL link to control bandwidth cost (ADSL provided bandwidth at about 11 times ISDN 128K and for about the same price, maybe a little more).
So! The big question is what can you afford in bandwidth, and will that bandwidth fulfill customer applications requirements for a few years? If not (for any reason, and after talking to the local phone companies' folks) ask for more money for your project.

I had a friend who worked in a building that was networked to the next building over via 2 methods:
therefore, the microwave link was aways up and running at ~300Kbit and the laser ran at 100bit/sec except for bursting to 1Gbit about 3 times a year for 30 seconds :-)
