[grc] How much bandwidth to run a VPN?

[Simon Frech]

Keeeth,

Are you sending a full WAV stream, like CD quality, uncompressed 16kHz, 44.1 kilobits per second? I found this calculator http://www.theaudioarchive.com/TAA_Resources_File_Size.htm#Bit_Rate_Tutorial
and it tells me that this would take 1411.20kbps, or 1.4112mbps. You’d want to have some extra, so if the ISP can give you 2mbps I think you’d be fine, and you can use the same link for the telemetry, i.e. access the transmitter remote control and look at the codec.

A VPN would make it more secure, it’s like your own line on someone else’s network. If you have a public IP address it’s easy for you to access the transmitter from anywhere, but that also makes it more vulnerable to hacking. The private email address would just be on the ISP’s network, you’d have to be on that network to access the transmitter, unless you set up your own network bridge. 

Hopefully someone else will weigh in and make sure I’m correct on this.

Congratulations on almost being on the air!

Simon
