Mobile IM is getting some hype, but has a long way before it can take over SMS. The way I see it - SMS is king, and it is here to stay. This is mainly due to the ease of use one enjoys with SMS. Today, at least, IM usually involves a buddy list and presence information. Once you connect to someone (a “buddy”), you will be able to see his presence status and send him an instant message. If

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

There’s no presence in TelePresence. And you know what? There’s also no “unified” or “communication” in UC (Unified Communication). These are just new buzzwords in VoIP town. They are there to replace “video conferencing” and “convergence.” Besides the fact that they are more of the same (maybe better), there’s nothing new under the sun. TelePresence TelePresence is simply better video conferencing. It has higher resolutions (1080p instead of 720p, or CIF if you refer to legacy systems), higher bitrates and

You can do everything with SIP: Voice over IP, video telephony, presence, instant messaging, SMS, MMS and much more. Sometimes it feels like SIP is a protocol invented by a salesman: “Oh, you are looking for a solution that starts the microwave when you get to your driveway after a long day? Sure we have it - SIP!”Last week I wrote about XMPP versus SIMPLE, where both are used for presence and SIMPLE and utilize SIP for its transport. A

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

Developing a videophone or any other telecommunication client? You should start thinking seriously about IMS. Today, there are two main standards used for multimedia communications over IP: SIP and H.323, where SIP is the standard which is being adopted by most vendors today - especially in the consumer market. As 3GPP, 3GPP2, TISPAN, Packet Cable and WiMAX have all selected IMS for their next generation networks, it goes without saying that a lot of vendors will start working on IMS

It’s the beginning of 2008 and of course, people love to make predictions for the year ahead (if anything to guarantee a good laughter after all). Yours truly is not an exception - this post was thought to appear under the name of Crystal Ball 2008, and it was supposed to make a number of bold (how else) predictions regarding the future of the communication technologies for upcoming year. Thinking about it, isn’t it great to know what the future
