I agree that bandwidth overall is generally sufficient for most apps. The problem with networks is the average performance and the latency. If there can be a guaranteed minimum bandwidth for download and upload and reduced average latency, we will get better quality in video conferencing or HD streaming. Latency matters a lot more in live video conferencing situations since there is no buffering and even consumer apps like Skype and Facetime suffers screen freezes and frames lagging. Until we can reduce average latency and guarantee a min. bandwidth, we will always suffer from poor video conferencing quality.

Very interesting statistics in your infographic, Pat, thanks. The average upload speeds across the world are most interesting to me. These speeds, are the *actual* or *advertised*. For example, for me in the UK, I am 1.7 miles from my local DSL exchange by the crow flies, but 7 miles by the way the cable travels (!!!). I get an upload speed less that 1Mbps on what is advertised as a 20 Mbps (download) service. So for using apps such as IP Telephony, the upload speed is a real constraint (never mind real time video upload).

Hence my question: are your figures *actuals* or *advertised* ?

thanks
Stephen
