Dr. Z is on vacation in Ireland.

He has been traveling from Dublin to Southern and Southwest Ireland. There is wi-fi in every town but the upload speeds are too low for viable video communication. The download speeds are usually good.

What is upload and download? Internet works like a two-way street. Download is when you receive information from the Internet to your device. Upload is when you send information from your device to the Internet. Most of the time, the download speed is much faster than the upload speed because we get more information on our device than we send it.

For good video communication, the upload and download speed need to be over 1.0 Mbps…when you access www.speedtest.net, it allows you to test the upload and download speeds. If it is over 1.00 for both upload and download, you should be able to do good video communication. If it is below .50, you might have trouble communicating via video. Most of the time in Ireland, the download speeds are over 1.00 but upload speeds have been between 0.10 and 0.30.

Dr. Z will continue to test wifi as he travels the next few weeks and report back.

By the way, Ireland is such a wonderful country, with beautiful sights and great food!

Dr. Z cares about your communication access.
