I’m not offering up answers here, I’m asking! 

I’ve been rereading the May 9th press release from Jajah announcing their investment funding from Intel. No doubt this is a huge affirmation for the Mountainview CA/Luxembourg company. About a year ago, I remember messing around with their beta and the free five-minute call anywhere deal. But now I need help drilling through the finance-speak to get to what Intel really means for Jajah current and future customers.

Jajah will now have “access to [Intel’s] extensive community of product dealers, OEM customers and developers, to further their reach into global development communities. As an Intel Capital portfolio company, Jajah will also be able to participate in Intel Capital’s IP Access Program, which will give Jajah access to Intel’s extensive VoIP patent portfolio.” And Trevor Healy, Jajah CEO says “JAJAH can be embedded into Intel solutions”.

So, what will embedded Jajah do for me as a consumer? In the future, will I be buying a laptop powered by Intel with Jajah on board?

Let me know your thoughts please!

(BTW, does anyone else have trouble typing “Jajah”, or is it just me? I get jajaj, Jahjaj…)

One thing I wish for in my quest for perfect Internet phone service the ability is to fix voice quality problems on the fly or at least be able to understand “is it me or the network?”

When I had Vonage service, I usually started the converation with “So how do I sound, can you hear me?” Many times there was such a delay that practical converation was impossible. If I was at my computer, I’d try quitting applications to see if that helped (usually not). After hanging up in frustration, I’d try messing with the dreaded ”Bandwidth Saver” feature. But in my opinion, AFTER the call is way too late.

Is it possible to build intelligent applications that KNOW when they’re not performing optimally and can tell you what the problem is, or better yet advise how to fix it?

No sooner had I written this when Peter Csathy, CEO of SightSpeed, let me in on a little secret (okay well it’s not actually a secret…), SightSpeed detects when your video or voice call isn’t going so well and automatically makes adjustments to improve the quality.

For example, a video call that appears jumpy or out of sync with the audio could be caused by network congestion. SightSpeed can downsize the bandwidth usage for video so that at least the voice aspect of the call is preserved or improved. SightSpeed lets you know it’s doing this by popping up a dialog box that says it’s making these adjustments. I don’t know if you can you make adjustments yourself DURING a video call, but you can easily see your upload and download speeds while talking to someone.

To see SightSpeed statistics: 

With your mouse hovering over the SightSpeed title bar,  press CTRL + S (or right mouse-click followed by CTRL + S). A statistics dialog box appears showing your current, peak and average bandwidth usage.

Gizmo Project has a Call Quality Assistant (click the bar graph in the bottom left of the Gizmo Window) that gives you an idea of your network conditions. While it shows you at a glance the quality of your connection, it doesn’t say what you should do about it and at this point in my life, that’s what I need.

You may have heard this before: Voice Over IP (VOIP) needs a certain amount of bandwidth to be usable. In other words, VOIP needs bandwidth so that voice conversations are intelligible by both parties. Your broadband Internet connection (provided through a cable or DSL service) provides that bandwidth.

Basically, bandwidth is the amount of digital data that can be transmitted in a certain time period. Internet connections are usually measured in KiloBits Per Second (kbps). Your connection may be rated at 512/128 kbps. This means that the upload stream (leaving your computer) has a maximum bandwidth of 128 kbps and download stream (coming to your computer) has a maximum bandwidth of 512 kbps. Find out the speed of your broadband connection…

For example, a web page that is 3000 bytes can theoretically viewed in 0.05 seconds – almost instantaneously - at a download speed of 512 kbps. However, in the real world web pages don’t usually load that fast.  That’s because data is held up, or delayed by various factors. Latency is the delay caused by the physical limitations of each piece of hardware the data is passed through. Delays are also caused by pathway congestion, error checking, transmission negotiations and extra data sent with the web page to identify its type, origin and destination.

What this means for VOIP is that enough bandwidth must be supplied to allow for the transmission of the actual voice data in real time as well as extra bandwidth for the overhead required for any data transmission.

So how much bandwidth does voice data use up? Well that depends on the codec (enCOder/DECoder) used to compress the data. Anywhere from 16 to 64 kbps is normal. Add onto that the extra overhead of about 10 to 24 kbps. In total, VOIP uses 26 to 88 kbps. As a general rule, assume that you will need at least 88 kbps to use VOIP reliably. Note that VOIP service providers will provide you with their broadband requirements.

You will need an Internet connection that can handle at least 128 kbps on the upload side. Extra bandwidth will allow others in the household to surf the net or download files while you are talking on the phone. If you wish to use conference calls even more bandwidth will be required.

While there is no set rule for the amount of bandwidth that a household will need, count on 128 kbps as a minimum.  If you have several computers and other devices connected to the Internet, consider going up to the maximum available.

Note that these speed are for uploads – the download speeds are usually quite a bit faster and present no problem for VOIP.
