Everybody talks about Unified Communications. If you once wrote a PBX, now you call it UC. If you developed IP Phones, now you brand them as UC. The only problem I see with all the hype around this is that UC is targeted at the enterprise. It’s not that I don’t like enterprises - I work for one, but I think people are missing the consumers on this one. Presence and the Enterprise About three years ago I talked

IntoMobile reports that Samsung also ditched Linux on one of its planned handsets, that after Asus did the same - this is counterintuitive to my thoughts on Linux on mobile, but I still stand by my conclusions - Windows Mobile is going to lose some ground if it doesn’t do something earth shattering soon. UC is not just about communications and it is also overhyped - I totally agree. Up to the point of there’s no such thing as UC. Skype might have a back door for governments to eavesdrop - there’s no security in proprietary protocols, only in open standards. Some shameless self-promotion - we just released our eVident product, which allows companies to test their networks for video deployment readiness.

There is no such thing as Unified Communications or Social Media. For that matter, Web 2.0 and Phone 2.0 are also non-existent. And there’s no Presence in TelePresence either. For the last decade, I’ve been a player in these worlds, working on either development or marketing of related building blocks for this industry. During that time, only three things have changed: There’s a lot more bandwidth waiting to be used There’s a lot more processing power There’s more acceptance

Interesting times in the mobile handsets arena. VisionMobile maps the new centers of gravity in this industry. I believe competition will lag behind Apple’s iPhone in their next release as well as copycatting its ideas and designs. Talking about the iPhone - I am thinking of starting a petition to ban iPhone from Google Alerts for 3G video. For the past two weeks I am getting nothing from that service besides iPhone jailbreaks and teardowns. Growing bandwidth and increasing CPU power will change television as we know it. It will also speed up the use of video telephony adoption and quality and this fits well with the trend of multi-core diversification I have written about. You can add to this TiVo’s two new deals with YouTube and Amazon - it’s only the beginning. HD is seen by some as the true promise of VoIP - this is certainly different than the Unified Communications pitch. What happens when you don’t have enough bandwidth though?

Presence is always positioned as the key to unified communications (UC) - at the very heart of UC is the ability to discern the current status of people and resources. Which protocol will be the one used to power Presence? SIMPLE or XMPP? XMPP XMPP stands for “Extensible Messaging and Presence Protocol”. It is a streaming based protocol that routes XML messages between entities. It is mainly used for presence and instant messaging although other uses for it exist

Two weeks ago, RADVISION hosted the IMTC SuperOp! 2008 event. The most obvious conclusion from this event is that multimedia conferencing (or should I say Unified Communications) is getting better – at least in terms of interoperability. Without exceptions, all companies successfully connected video sessions with one another. The IMTC SuperOp! event is the main interoperability event of the IMTC. In this event multiple activity groups, each dealing with a different multimedia communications technology, gather in a single room to
