Just had a very pleasant 54 minutes video call with Sweyn Hunter using Google+ Hangout. My Huaweii 4G MiFi (courtesy of EE) tells me that it used approximately 315MB of bandwidth – probably slightly less as I did some emails before hand.
At Sweyn’s end he had “good old fashioned BT ADSL” with maybe 512k uplink speed. He lives in Orkney. The video quality was great though it did freeze two or three times in the 54 minutes. The only slight issue was an element of half duplex/one way speech in that if he was speaking and I tried to speak at the same time. I quickly got used to that and it didn’t detract from the quality of the conversation.
Also 54 minutes was a long hangout for what was just a casual chat – I’ve never met Sweyn but converse with him from time to time on Twitter – @sweynh – I’m sure he won’t mind me telling everyone. The point being that if we were comfortable having a 54 minute video conversation the quality must have been good – otherwise we would have cut it short.
Sweyn is an interesting bloke I’m sure he won’t mind me saying – you should follow him. He is organising an Island Govcamp in Orkney next year on 6th and 7th September.
Might try a hangout using O2 and Vodafone sims in my various phones next time. It will be interesting to see if personal video calling is going to at last get mainstream with 4G. Bandwidth cost is still going to be an issue. You can work out for yourselves how quickly you will eat up your own data bundle.
