[Techtalk] Extending the network

[Dan Richter]

Hi everyone.

My in-laws run a small business that's grown beyond the space that's 
immediately available to them. They want to put an employee in a 
building across the street, and they want that employee to have access 
to the corporate network.

I assume that Wifi is too loose on security. It wouldn't be appropriate 
to stretch an ethernet cable between two windows, but there is 
line-of-site, so an infrared transmitter might be a solution. It may 
also be possible to set up a VPN (Virtual Private Network) operating 
across the Internet.

What do you think would be a good solution? I'm not a network admin, so 
please explain the hardware and setup costs involved.

By the way, no one in the company is a geek, but they pay a geeky 
company to take care of their network.

Thanks.
