Today is Blog Day 2008

This is the first BlogDay I actively participate in as a blogger, though I have been exposed to the previous one. I found it interesting and useful to see what fellow bloggers tend to recommend. So here’s my list of 5 blogs for BlogDay: 1. No Jitter No Jitter is a blog related to the VoiceCon event. Now that VON is gone, they’re the water cooler of our industry. If there’s a good place for insights and good analysis regarding (read more...)

What Does Skype Have to do with iPhone and User Interfaces?

iPhone 3G is by far the most hyped phone (or even product) out there today. Everything about it is great - even though you can’t get coverage, have lousy battery life, buggy OS updates and general instability when you call, the party in the Apple AppStore is going on without a stop, with over 30 million dollars of sales in the first month alone. iPhone iPhone really changed the mobile handsets market. Other than making the concept of downloading applications (read more...)

VoIP from around the net: August 27, 2008

Michael Mace at Mobile Opportunity complains about market share statistics - he is so right, and it’s not only the smartphone market, it is virtually any market and any product. You can read about this also in this week’s Carnival of the Mobilists. The removal of VoIP from Nokia’s handsets is pushing customers to iPhone and Android - not sure I agree on this one. Luca Filigheddu is on the spot here, as the N-series from Nokia is for the consumer market, most consumers don’t care if they call using VoIP, 3G, GSM or whatever. Speaking of Nokia, Joel Spolsky chose Nokia E71 over the iPhone 3G - the iPhone is not a one size fits all solution. Not VoIP related, but surely IP related - Cringely takes a jab at numbers, building predictions on the future from Cisco Certified Internetwork Experts statistics. Nice to see my country (Israel) doing well in his results. Another great one by the Cranky Product Manager - if you had to deal with engineers in the past (or if you are one), this one is definitely something you should read.

Carnival of the Mobilists #138 at MobHappy

Another week; another carnival. This time, it’s over at MobHappy. There’s a bunch of great content there without a specific theme this week -iPhoneless at last. I made it to the carnival with my post about going green and VoIP.

Introducing: RADVISION’s Blogs

The VoIP Survivor blog has been around for over 6 months now. During that time, I have tried to make it an interesting place for people who are working with and around VoIP - be it desktop clients, mobile handsets, or server side solutions. We have also tried to develop more interesting blogs around RADVISION’s fields of expertise. I’d like to take the opportunity and introduce my fellow RADVISION bloggers. Meet the writers The RADVISION blogging community currently consists of (read more...)

Optimizing 3G Video Telephony For Longer Battery Life

3G Video Telephony is powered by a protocol called 3G-324M. 3G-324M is circuit-switched based, so everything you send is sent as a single bitstream at a fixed bitrate of 64 kilobits per second. On that single connection, you can send voice, video, data and signaling. Since there’s not a lot of room 3G-324M uses a very efficient multiplexer protocol called H.223. The only problem is that implementing it properly isn’t that easy. For that purpose, RADVISION has developed an efficient (read more...)

VoIP from around the net: August 20, 2008

Tim Bajarin from PC Magazine writes about the dawn of visual networking - Sagee on his Video over Enterprise blog is saying that all of the time and I must agree with the conclusions. Video is here. Another one about video going mainstream, this time from No Jitter - I am betting video will happen in all of the three buckets mentioned in this post, and that the key is going to be the ability to mesh them up together. Sam Dean on OStatic asks if Mobile Linux is having difficulties due to Orange ditching Access Linux - I don’t think so. The market is going to consolidate around seven centers of gravity, so the smaller ones are heading a hard time, but Linux will thrive. Nortel just acquired Pingtel. Garrett Smith has an interesting (and probably controversial) analysis on this one.

Join us at the Carnival of the Mobilists #137

I have decided to join a carnival - the Carnival of the Mobilists. What does it mean? The Carnival of the Mobilists is a virtual meeting place where the very best posts written about mobile are exposed each week. Every week, the carnival travels to a different host - a blogger, who picks and chooses the posts he wishes to share with his readers. So what happened this week? This week was the first time I got into the Carnival with my comparison between SMS and Mobile IM. This week’s Carnival was hosted by mobilejones, who also tried for the first time to add Twitter to the carnival. I must say that the collection of posts there is excellent.

Is There Room for Mobile VoIP in a World Going Green?

Going green is all the rage these days. Slowing economy, raising gas prices - just what you need to fuel up video conferencing. When all around us, people are trying to reduce energy use, is there any room for solutions that are power intensive? VoIP seems like a great solution when used for video conferencing, but when used on a mobile handset it might be a different story. I ran by a post in Martin Sauter’s blog, WirelessMoves, where (read more...)

SMS vs. Mobile IM

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 (read more...)
