Telesphere Videoconnect: Videoconferencing in the cloud!

If analysts are to be believed, the videoconferencing and telepresence market will more than double to $5 billion in annual revenue over the next four years. In this context, Phoenix, US-based Telesphere has introduced the VideoConnect, a hosted video service that promises to enable any size business to implement videoconferencing quickly and cost-effectively by targeting its webcam-equipped PCs, room-based video systems, videophones, smartphones, tablets and softphones.

Telesphere VideoConnect expands the company’s already broad range of cloud-based business communication solutions, such as hosted voice, hosted call center and hosted call recording for businesses.

So, what exactly is Teleshphere Videoconnect and how does it make use of the cloud? According to Sanjay Srinivasan, CTO, the VideoConnect is a hosted video conferencing service that allows callers to join reservationless video conferences using a variety of end points, including video phones, tele-presence room systems, softphones with webcams on PC, and also targets the multitude of tablets and smartphones. It supports HD quality video.

“All of the bridging/conferencing intelligence resides in the cloud and the end users need not have and operate complicated video equipment on premises. Additionally, being in the cloud, it removes the complexities of having to deal with firewall and NAT traversal issues as it is based on industry standard IP protocols. Users join a video conference by dialing in to a bridge, and entering a passcode,” he added.

Naturally, that leads to what the hosted infrastructure involves. Srinivasan said: “The infrastructure involves amongst other things the bridging/conferencing systems and network session border controllers to allow seamless NAT/firewall traversal and bandwidth control/management to support a variety of network bandwidth availability situations.”

In call bridging, it says that up to 12 simultaneous legs can be enabled. Does this mean that up to 12 users can be on one call on Videoconnect? “Yes,” said Srinivasan. “Up to 12 users/legs can be on a call. Of course, if one of the legs is a conference room, that only counts as one leg independent of the number of people in the room, assuming that there is one camera in there.”

One-to-one calls are kept free, for now. Therefore, does it mean this is a free solution for most users? He said: “This means that two endpoints on our network are able to have a peer-to-peer video call at no charge. A good example of this might be a multi-site customer that has people having video calls with each other and if they use a video phone with good sized screen, they can use it for ad hoc conferencing as well.”

Now, what kind of pricing strategy has Videoconnect firmed up, if at all? “The pricing strategy will be made available in updates coming soon. However, the overall strategy used will be in line with the concept of hosted services in general enabling customers to leverage this capability with monthly fees,” concluded Srinivasan.

Available to select Telesphere customers immediately, the Telesphere VideoConnect features an intuitive user interface (UI) and hosted infrastructure that combine to create a nearly flat learning curve for employees.

Ether 1.3.1 phone adaptive antenna solution integrates with smartphones!

July 14, 2011 Comments off

San Diego, USA based Ethertronics Inc., enabling innovative antenna and RF solutions to deliver the best connected experience, has launched Ether 1.3.1, a phone adaptive antenna solution. Ready for integration with smartphones or other classes of phones, the Ether 1.3.1 can realize design benefits such as 50 percent reduction in antenna volume, yet maintain compliant performance.

According to Laurent Desclos, president and CEO, Ether 1.3.1 allows an antenna system to dynamically tune itself for optimum performance.  Phone form factors are constantly changing throughout the design cycle.

“Current solutions, using passive antennas, require the antenna to be re-tuned with each change to the phone form factor, lengthening the time to market. Ether 1.3.1’s advanced active circuitry is able to adapt to changes in the form factor, reducing the need for lengthy antenna redesigns.”

In addition, Ether 1.3.1 can be designed to take up less volume than other antennas (up to a 50-percent reduction), providing more space for other components, and yet, still remain specification compliant.

Is this solution only suitable for smartphones then? Desclos said that Ether 1.3.1 is not limited to just smartphones.  It can be integrated into all tiers of devices such as feature phones and tablets supporting 2G, 3G, and 4G mobile device designs. Ether 1.3.1 is said to be ready for commercial deployment. Several design references have been accomplished to date. Products from OEMs will be announced in the future.

It is said that Ether 1.3.1 allows more freedom in antenna structure design. Elaborating, Desclos said: “Ether 1.3.1 allows more freedom in antenna structure design in a few core areas: size, placement and ability to meet performance specifications. Through the use of active impedance matching techniques, smaller volume antennas can be achieved.”

This is especially important as phone form factors shrink, while more components are added to phones for increased functionality (cameras, GPS, etc.). Ether 1.3.1 can additionally be used to achieve compliance as the antenna system can be dynamically tuned for known challenge areas in specification compliance.

Finally, how can the Ether 1.3.1 solution be tuned for tougher challenges by toning down the antenna size?

Typically, when the antenna’s size is decreased, performance suffers since there is less volume area to cover the required bandwidth. The beauty of active impedance matching is that the technique allows for the antenna volume to be reduced by as much as 50 percent and still maintain compliant performance. As a result, active impedance matching allows for a wide range of designs, since the technique is applicable to a broad range of form factors.
