VoCeM - Go See 'Em More for Less

Bottom line good reports from TriaGnoSys, a satellite communications company, launched VoCeM, the world's most efficient satellite communications compression software. Currently, voice over IP (VoIP) calls use up to 96 kbit/s, GSM use up to 30 kbit/s; using VoCeM, each call will only use 6 kbit/s. Satellite costs are therefore reduced significantly, meaning call costs for the end user can be much lower.

VoCeM reduces the kbit rate for calls, and increases the number of simultaneous calls each satellite link can handle. Using the VoCeM compressor, Inmarsat or Ku-band payload usage can be increased by a factor of between 5 and 10.

The VoCeM software has been designed to be installed on existing GSM, 3G/UMTS and VoIP communications servers, so no hardware upgrades are involved. In addition, the considerable cost savings mean VoCeM provides a quick return on investment.

VoCeM can be used for all forms of remote communications systems, including passenger and crew GSM and VoIP services on cargo and cruise ships, aircraft, and remote terrestrial sites, such as oil fields and mines.

TriaGnoSys is perhaps best known in the in-flight entertainment and connectivity (IFE&C) industry for supplying the software behind the Airbus/SITA partnership OnAir's onboard GSM mobile phone solution, which uses Inmarsat's SwiftBroadband satcom. However, TriaGnoSys also recently made headlines when it teamed with T-Mobile, VT Miltope, and ViaSat to offer a Ku-band satellite broadband and GSM telephony service for air transport. The T-Mobile-led team is involved in discussions with Lufthansa in relation to finalizing a contract that would reinstate Ku-band-based connectivity services on the carrier's overseas flights.

D-Link DPH-540: First Flip-Style Wi-Fi Phone


D-Link showcased the industry's first flip-style mobile Wi-Fi phone that includes a complete softphone from TelTel for SIP-based Internet telephony, enabling users to make free calls whenever they enter a Wi-Fi hotspot.

The phone, dubbed DPH-540, looks like any cell phone but is not compatible with GSM/CDMA networks. For a Wi-Fi phone, it's pretty lightweight and compact, at just 3.74 ounces. Adorning the internals is a backlit color LCD, as well as a backlit keypad for easy readability.

One of the biggest advantages of using such a phone is that you don't have to be in front of a PC to make/receive calls. Moreover, the phone interface is easier to operate than a PC. Other featuers of the phone include standard speed dial, multiple ringtones, e-mail access and volume control.

What's more, calls to TelTel users across the world are free. You won't need a bigger incentive than this to opt for a Wi-Fi phone. Of course, the problem is, it may turn out to be expensive for local calls to fixed-line phones - which means you will end up carrying another phone with you.

On display at the Sprint Voice Over Network (VON) Conference and Exhibition at the San Jose Convention Center till March 17, the D-Link DPH-540 carries a price tag of US $250 and will be available this summer.
