It seems like consumer video chat is set to grow – at least if you believe GigaOm’s research paper and Apple’s latest move with iPhone4 FaceTime service. There is though a huge install base that is being neglected here, which is the one that does mobile video telephony over 3G networks using 3G-324M. It has been around for years now, running across continents, operators and handset vendors. You can read more about its past and future at Vision Mobile. A

FaceTime is a really interesting move coming from Apple on their recently launched iPhone4. It is a mobile video telephony service which runs over IP, which by now probably have had more video calls done than mobile video calls done on all other existing handsets in the world in the same period of time. Instead of spending my time thinking of what else to write about this new service, here are a few interesting posts that I have found in

It’s funny how things go sometimes. Just yesterday I’ve crowned my day as the day of LTE – not because of any special reason, but simply because I bumped into too many LTE related posts in the blogosphere. Here are the interesting ones: It all started in the morning, when Andy Abramson coined LTE as Long Term Excuses. It brought me to Dean Bubley’s blog – a new blog I now added to my reading list. There

I actually haven’t got a clue, but Sagee told me I should write such a post so I did. Let’s see how it goes… iPhone OS 4.0 is now “out”. If you are looking for the official feature list, one of the best places for that would be Kevin C. Tofel’s post over at GigaOm. If there’s any quote from that post that you need to remember it’s this one: “… But the implementation approach and polish of these

There’s been a lot of talk lately about mobile VoIP. People feel like the mobile operators are about to lose their businesses to all those startups offering free and low cost calling by utilizing the data path of cellular networks. I have provided my views already on why I think these startups are not growing anywhere, and why IMS will wipe them out of the market altogether. Guess what? I’ve been prophetic in this one. This week, a distinguished group

VoIP blogs have been filled with optimism lately about the prospects of mobile VoIP. Om Malik reports about this: But two recent statements by carriers from different parts of the world are making me wonder if the mobile phone companies are softening their stance on mobile VoIP. Last week, Verizon went out of its way to highlight the fact that it had tested VoIP calling on its new 4G wireless network. (The other 4G wireless company, Clearwire, has warmed up

Dave Michels wrote a thought provoking article over at NoJitter, where he came to the conclusion that the IP Phone has peaked: The handwriting is on the wall, and rather than mourn the IP Phone, we should celebrate its short life. Perhaps “mourn” is too strong; its decline will be slow. Death in this industry is extremely slow–consider all the dead digital phones still freshly manufactured every day. So while death may be a point of contention or exaggeration, decline

Eric Krapf shares a presentation of John Giese from Avaya, which practically kills the idea of the PC as a phone – it’s a bit too harsh for my taste, but rather in-line with my own thoughts about desktops and IP phones. Still on NoJitter, DaveMichels sees things a bit differently, stating that IP Phones have peaked, and will be replaced by desktop and mobile phones. Stacey Higginbotham GigaOM reports on an increase in upstream bandwidth use – if this trend continues, it will be another step towards visual communications for consumers at home. Andy Abramson from VoIP Watch indicates what aspects of the App Store phenomena worries Google – his analysis is sound, though I don’t see App Stores catching over web browsing in the long run.

Cory Andrews from VoIP Supply briefs about SIP Intercom systems from Cyberdata – it’s nice to see more types of communication products adopting SIP. This will definitely increase the innovation and usefulness of what we do as an industry. John Gallagher over at the GIPS blog provides statistics on HD Voice from a recently held webinar – just in time for the HD Communication Summit. The IMTC, an organization dealing with VoIP multimedia interoperability, has
