Over the past couple of days I have had the opportunity to complete calls using Skype for iPhone 2.0 over 3G to contacts in the U.K., the U.S. and Spain, not only while staying in one location but also at 100 km/hr crossing through several mobile phone cells along Canada’s busiest freeway that recently was equipped with a 3G/HSPA+ service by Rogers. Some of the outcomes:

Launching the application

First, we are still dealing with an iPhone that does not allow multi-tasking but Skype for iPhone only serves to build the anticipation of iPhone OS 4.0 and its multi-tasking feature. As a result you currently must be logged into the application to receive a call; not only that, each time you log in, it can take 30 – 45 seconds for your Contacts’ current “presence” status to appear. (And you need to ensure your own status is set to “Online”.)

“Near CD-quality voice”

Once the presence information is current, however, select a contact, make a call, get an answer and start the conversation. What follows is a recording of one of my first calls where Voxygen’s Dean Elwood set up a three party conference call via Skype for Windows on a PC. (Skype for iPhone itself cannot set up a multi=party conference call.) Pamela’s Call Recorder was used to make the recording. Listen for yourself.

Dean makes an important point during the call about how Skype’s SILK-based superwideband audio makes it much easier for him to understand all the various and several English accents he needs to deal with in the normal course of his business activity.

Note that, in order to maintain the audio integrity of the recording, no audio editors were used to filter out “ah’s” and “eh’s”, etc.

Moving Along the Freeway with Skype

First, for all those concerned safety advocates, I was not driving my car during these calls.

From Ontario’s 401 freeway (the main route between Toronto and Ottawa/Montreal) between Trenton and Cobourg, Ontario I made a 25 minute call to Andy Abramson who was on the I-5 in and around San Diego, California. At one point both sides had speakerphones going such that we had a four-party car-to-car conversation.

While providing the same crystal clear voice quality reported yesterday, the call also was sustained as we both passed through several cells of our respective networks (I could see the cell towers alongside the freeway). Let’s just say we were both traveling at or near the legal limit and there was no degradation of voice quality.

There was one point where we noticed a bit of fuzziness (along with an appropriate warning on the call quality indicator) but it recovered very quickly and the call connection was not lost. The other issue was not really a Skype issue but the volume had to be turned up a bit to overcome the automobile’s inherent background noise.

Battery Life

It’s still an issue. I found that leaving Skype for iPhone open continuously for over three to four hours would drain the battery. A significant challenge for iPhone OS 4.0 will continue to be battery life. It’s the one significant shortcoming I find with respect to overall iPhone performance.

Data Use

From initial observation, it would appear that about 2 minutes of a voice call will take up 1MB of data transfer. Simply a guideline but it can start to get a handle on what your data costs will be. I still would only recommend using Skype for iPhone over WiFi when roaming outside your home network.

Bluetooth

Andy Abramson reports that his attempts to use a Bluetooth adapter while making a Skype for iPhone call have failed. More investigation and feedback required.

Bottom line: Skype for iPhone 2.0 has brings new performance benchmarks to the mobile voice calling experience, especially when it comes to voice quality. However, lack of background processing and improved battery life management still make it questionable as to whether one would rely totally on Skype for iPhone for all one’s mobile calling.

But it’s impeccable for making outbound calls to all your Skype contacts where you as the user have total control of the calling activity. And, of course, the call cost is also right.

It’s an Always-On Life

But the most difficult aspect to become accustomed to, especially as I was driving along the freeway today, was to be aware that one could always be connected to Skype whether via a WiFi access point or a wireless carrier, provided the battery had not been drained. I could follow Skype chat conversations, see others’ presence information and mood messages and, if appropriate, make a (currently free) voice call. There’s a psychological shift in thinking that has to be made.

Note:: Ontario has recently introduced laws that prohibit texting while driving as well as making voice calls other than handsfree calls. And the stats showed that texting while driving can be as dangerous as impaired driving. Pull over to the side of the road or turn over the driving to another party if you absolutely have to engage in or continue “that conversation”.

At eComm Spring 2009, Skype executive Jonathan Christensen announced that their recently released SILK codec would be available to third parties royalty-free. Two weeks ago at eComm Europe phonefromhere.com’s Tim Panton gave a presentation “Deploying the SILK codec, How and Why” where he discussed two projects where he was involved in embedding Skype’s SILK codec into a voice-enabled service under projects managed by Dean Elwood’s Voxygen product and services deployment company. From the overview for the presentation:

SILK’s royalty free licensing combined with it’s non-TDM heritage allow us to focus on the user and what they have available instead of obsessing about attempting to manage the network.

Last week came a press release announcing the beta release of Blabbelon, the first browser-based voice chat and push-to-talk tool targeted initially at the Internet gaming market.

As communication companies continue to look for new ways to generate revenue with VoIP applications, keep current customers and lure new ones, Blabbelon enters the market and completely changes the rules of the VoIP game. The first browser-based VoIP chat tool using Skype’s SILK super wideband audio codec, as well as one of the first massively multi-user VoIP services, Blabbelon can handle thousands of simultaneous users at a fraction of the cost per user of other traditional services. Blabbelon provides a platform for a wide variety of users such as: gamers securely competing in team-based quests; businesses running 7,000 person global conference calls; or grandparents taunting grandkids over a game of Facebook Scrabble.

I spent some time yesterday in a Blabbelon session with Dean to experience the service in action. Out of this session came the following points:

• Push-to-talk voice sessions comprise a common feature of Internet gaming sessions; however, Blabbelon brings a new level of ease-of-implementation and ease-of-use, with the goal of having a simplicity of adoption similar to what Skype experienced because you simply installed it and started calling and talking.
• In fact, being browser-based means there is no download required. Once a session leader has launched a Blabbelon session s/he simply needs to distribute a URL to other participants in a game to allow them to join the session.
• It’s push-to-talk but there is a hierarchy established to manage who has “talking” rights. The entire experience of having a discussion is very similar to CB Radio or a “direct connect” two-way radio service where, with the simple push of a button, one can speak instantly to a designated team of participants in an activity, such as a construction project.
• Blabbelon sessions can scale up to more than 7,000 users in a low cost business model. In fact their press release talks about its being ideal for online auctions. Is this the style of voice service that Meg Whitman should have acquired for eBay instead of Skype?
• Use of the SILK codec certainly supplies a crystal clear sound while using a minimal amount of bandwidth – very important for gaming sessions that can become very CPU intensive. Again from the press release:
  

  Users can run Blabbelon in their Web browser, while simultaneously using other online applications – with no impact on their overall network performance, since Skype’s SILK codec was designed to use approximately 50 percent less network bandwidth than previously required, while delivering improved richness in audio quality.”

• As for the initial target market:
  

  Blabbelon will initially focus on a core audience of the millions of online gamers and players of Massively Multiplayer Online (MMO) games such as World of Warcraft (WoW). The combination of Blabbelon’s technology and features and the SILK codec provides a perfect tool for this market, which, because of the cooperative nature of games, needs a no-download, high-quality, secure, reliable and scalable voice chat.

More background from the press release:

Blabbelon was created by a team led by CEO Ed Ikeguchi, former co-founder of Medidata Solutions (Nasdaq: MDSO); Dean Elwood, CEO of telecom provider Voxygen Limited and chief technology strategist of Blabbelon; and Rowena Rubio, CMO and former systems analyst.

Available immediately [as a beta offering] from www.blabbelon.com, Blabbelon is hosted by Rackspace, ensuring the highest levels of chat stability, quality, security and reliability. Blabbelon offers 100 percent uptime through Rackspace’s worldwide network and zero downtime guarantees.

Bottom Line: Blabbelon opens new directions for the application of VoIP technology and the SILK codec. It’s not a voice conversation service along the lines of traditional telephony. Yet it brings new ease-of-use and voice quality to a market that has been poorly served by current offerings. Of course listening to Dean on Blabbelon using a FreeTalk Everyman for Skype headset with its inherent support of the SILK codec ensured that the full benefit of the voice quality available from SILK was experienced.
