A colleague had emailed me this simple image a while back. They say sometimes an image can be worth a thousand words. I thought this image powerfully depicts the engineering challenges that lie behind making wireless networks ‘work well’. (I have no idea about the original source of the image, so if someone knows, please email it and I’d be happy to post credits).

IMS deployments – on the rise and around the corner
Are you surprised by the title? Well, that is really how I see things as it stands today. Based on my discussions with most OEMs and ISVs who have themselves been trialing all over the world for a few years now, we are just about at the phase when most trials are getting out into real deployment. Incidentally, incase you think that IMS all-IP ‘live’ deployments have not yet happened, think again. Remember, in 2006, there was an announcement that Wateem Telecom selected Motorola for a wimax deployment ? Well, that network does data and is ready for voice. Not sure if you knew, but that entire network is over an IMS subsystem (yes, you guessed it – WiMAX on its own is not a session specific architecture, while IMS is, so it makes sense to have IMS on WiMAX, huh ?). And yes, I mean R5+, which is all IP for both signaling and media. Several green field operators are already deploying or have deployed IMS driven networks (we work with many of them), but very few are touting the IMS name around right now, since IMS has been a long used, much abused and somewhat delayed technology. But

Everyone wants to be a YouTube
My apologies for not posting for a while. Besides my own family needs, I’ve been also travelling a lot the past few weeks and visited the usual shows like VoN, CTIA and others. (In fact, Jeff managed to catch me at his show here – I’m the one with the widest grin). It is always interesting to see what is the next big thing that is there in everyone’s mind. And it is no surprise when I say it is now, “Media”. A lot of my good friends have either started their own “Media” companies, want to start their own Media company, have started and have changed their business plan thrice already, or are hobnobbing with content producers and aggregators to see if it makes sense for them to start their own media company. And I use the term “media” in the loosest possible way, because so do they. What they want to do ranges from “Video Streaming” to “Digital conversion” to “lifestyle content” and what-not. I spent a full day at the CTIA’s Mobile Billboard event, where folks from AMP’D, MTV, Atlantic Records et al came in and spoke about how they view the next decade of media, and
