It all generally depends on the Internet usage during the call. Internet distances are not like geographical distances, and I frequently experience high bandwidth (and high quality calls) to the other US coast (that would be the East Coast) or even internationally while getting lower bandwidth and quality on local calls. On really bad days, I get mere 384 kilobits per second – luckily, the latest generation of video systems can deliver SD quality even over such low bandwidth.
The bad news is that the network performance is not predictable: sometimes I can connect at 1 megabit per second and enjoy high definition quality and sometimes I only get 512 kilobits per second which results in standard definition quality.
a colleague of mine has one in Atlanta, Georgia. I can also place calls to other telepresence systems connected to the public Internet, e.g. I have some experience with the technology – I have been using Polycom HDX 4000 personal telepresence system in my home office for a while and can connect to the Polycom network via a video border proxy that resides in the De Militarized Zone (DMZ) of the closest Polycom office (San Jose, California). The article mentions Quality of Service as an issue for all types of telepresence systems that connect over the public Internet. John Bartlett wrote a short article about compatibility issues with B2B telepresence at, and I believe this topic deserves deeper analysis.
