I need a solution for my up coming project, I need to make PC (A) and PC (B) talk to each other (access on demand) via "wireless solution".

PC (B) is at a remote location with only power supply, and PC (B) is running on custom OS with Tel. of LANconnection option.

PC (A) have access all comms.

PC (A) and PC (B) is about 2KM apart with road in between them.

Have think of using Nokia D211, but PC using custom OS not able to support.

Please Help! Thanks in advance.

There is not going to be a lot you can do if none of the devices support the OS that you are using. You can go to a more costly route and get the cisco aironet products or another wireless system that will cover a 2km distance then you can use ethernet to connect to this OS. Are their drivers for this OS for a NIC?

You REALLY need to do some homework here. "This is what I have" especially when a custom O/S is involved probably isn't the way to go. I agree that the FIRST thing is to figure out a protocol that can be agreed upon by both O/S's. Then take a look at wireless equipment that is compatable and will cover the distance. But you will need to build in a fudge factor to cover for spurious noise that can cause interferance. What is the environment between the two computers, major manufacturing facilities or open fields. Check it out and do some homework it will save hair pulling and money.

A bit light on information here, but with the custom OS in PC(B) it looks like an external device is the only option. If PC(B) can support Ethernet cards then wireless devices can be optained that can take power from the LAN connection (eg. Cisco Aironet). This could be a direct cable from PC(B). The wireless bridge option is feasible, but you will need a special antenna to drive it 2Kms.

Any other option would require extra power sources in PC(B) location. If that can be arranged the use oflazer and microwave become feasible.

First thing is to evaluate the capabilities of PC(B) custom OS.

The solution i really need is how to utilize the current I/O (Modem or Ethernet port). Security is also a major concern, therefore Aironet might do the job, but addition firewall need to be in place. Like to keep the connection as simple as possible. Thanks for submitting.
