Short range connection
Just speculating... Does a technology exist that can connect two locations that are some 2-300 meters apart without using teleserverices? The two locations are not visible from each other, so laser or similar is not an option. The bandwidth demand is very small, so the solutions should be very inexpensive. Anything like that?
Hello Kaare, What you mean teleservices? Wireless Lan perhaps? Regards On Friday 19 April 2002 13:01, Kaare Rasmussen wrote:

Will Wireless Lan work over 2-300 meters or more?
No, the current 802.11b LANs have an effective range of about 50 meters if there are not many intervening walls or a noisy environment. This range can be extended with properly placed antennae. There are more powerful radio LANs, but they are quite expensive the last time I checked, somewhere in the US$10000 range.

If you can run a copper cable between them, you can use null modems (long haul modems) to connect them through the serial ports. Your speed would be limited to the speed of the UARTs, usually 115k. You can also use 10 Base-5 (also called thick ethernet) but pulling that cable can be expensive and most network cards today don't have the required AUI port. You can also run fiber.

The cheapest way would be to use something called a Short Haul modem. Here is a link to one:(may be word wrapped) http://www.jameco.com/cgi-bin/ncommerce3/ExecMacro/Jameco/searchResult.d2w/report?sort=BPA&search=116581 -- use Perl; #powerful programmable prestidigitation

A short haul modem would work, but at 300 meters, you are within range of thick ethernet (10Base5). You might have a hard time finding any network cards or hubs that have the required AUI port, but I'm sure you could pick up a couple of transceivers from blackbox.com. See this link for specs and other info on 10Base5 ethernet: http://www.ethermanage.com/ethernet/10quickref/ch3qr_1.html Best regards, Keith -- LPIC-2, MCSE, N+ Right behind you, I see the millions Got spam?
