It seems like Apple has succeeded where others have failed – it has opened up the market in Korea for foreign handset vendors. And it has done so singlehandedly. Before the iPhone, most of the Korean handset market has been ruled by local vendors. The service providers in Korea had their own set of special specifications, usually written in Korean, making it harder for foreigners to participate in the game. One success story of a foreign company in Korea

In case you haven’t noticed the latest trend, our clients/terminals/endpoints are becoming diversified in almost every aspect, while our servers are being consolidated. I’ve written here more than once about the way that chips and platforms for consumer electronic devices and video conferencing terminals are going towards multiple cores, but where each core has different capabilities: you have a host processor, and a bunch of accelerators for video processing and graphics, encryption, baseband functionality for cellular and wireless, etc. We’re

I am definitely not a gadget freak – the mobile phone I use is the corporate Nokia 6120 classic and I am happy with it (!!!), but I am a workaholic – so, at home, my laptop is always open, the VPN is always connected, and I check my corporate email account frequently. Why am I telling you that about myself? Because some people think WiFi VoIP is going to replace 3G calling. Michael Graves, for instance, thinks DECT is

Last month I’ve mused about Mobile VoIP, first suggesting IMS will kill it and then stating it is not going to happen any time soon. I think it’s time I stand behind my big words and explain why. Here are my 5 cents reasons: 1. Mobile VoIP is (Still) Downloadable Mobile VoIP is yet to be embedded as part of the natural user experience of a mobile phone. There are some handsets that support mobile VoIP, but finding it, configuring

There’s a fashionable hype lately all around HD Voice, up to the point of “marrying” it with other technologies that make a lot of sense to us “techies”. But I must ask a “dirty” question: where the hell is the incentive for the consumer market? HD Voice does improve voice quality. I’ve used it at work. It sounds differently. You don’t want to go back to the crappy systems we have today on our mobiles and in our homes.

Know all of these great mobile applications that we keep seeing in the app stores? Especially the ones doing VoIP? Well, it seems like they’re not really made to stick – at least not if operators have their say about them. While one of the most interesting news out of MWC was the fact that Nokia N97 comes with a pre-installed Skype client and able to run on both WiFi and 3G, operators O2 and Orange are not thrilled. iPhone

I am happy to announce that RADVISION has just been granted another patent in 3G-324M. This time, it is about the technologies we have invented and promoted into MONA – the standardized mechanism that reduces call setup time in 3G-324M video telephony to below a second. Video telephony on mobile handsets today requires a protocol called 3G-324M. It is one of the show stoppers for the use of video telephony, and the creation of services such as ringback tones. This is due to the long amount of time it takes to actually connect a call – from the moment you accept a call until you see the video, you have to wait for an average of at least seven seconds. The technique that has been standardized for 3G-324M to reduce this time to below a second is called MONA, which is comprised of three different technologies. The most important technology, out of the three, is called ACP (Accelerated Connect Procedure). It has been invented and promoted by RADVISION and has just been granted a patent. In order to be MONA compliant, companies must also implement ACP, which is mandatory in the video telephony standard. This means that every MONA compliant handset is using our patent. If you are looking for technical information regarding MONA, I suggest reading our whitepaper on the different techniques for accelerating 3G-324M call setup time.

Mobile video telephony today is not the killer app we all thought it would be . I believe this is due to the technical difficulties involved. That aside, there are niche markets that make use of what is currently available in mobile video telephony. Just this week I bumped into a news piece on Israeli TV (Channel 2 News) about doctors in Israeli hospitals using mobile phones during their daily rounds and surgery procedures to help in difficult decision making.

Video calling is happening: 28% of Skype calls are video calls Asus just released a Skype videophone Quanta plans an ooVoo videophone Vidtel launched a video telephony service And there are a lot of others who are either interested or currently developing and preparing to launch video services. In the past several years, mobile operators around the world had the opportunity of launching a video service on their own, using a technology called 3G-324M.

I’ve been blabbering about 3G-324M mobile video telephony for a while here. Most of the stuff I’ve written, though not all of it, is quite technical. When Luca Filigheddu asked for guest posts, I said yes, and it was decided that a good topic would be the way services are provisioned in mobile video telephony. I’ll give a short spoiler here – to do services in mobile video telephony, which is circuit switched based in nature, you need to use VoIP. Head over to Luca’s blog to read why and how services are deployed in mobile video calling.
