Interference Reduction Technology Receives Patent

U.S. Patent No. 7,295,807 is entitled "Methods and Systems for Configuring Satellite Antenna Cell Patterns in Response to Terrestrial Use of Satellite Frequencies."

According to the patent's inventor, Dr. Peter D. Karabinis, the technologies disclosed are currently being developed for MSV's next generation satellite-terrestrial 4G network and are expected to result in customer benefits including improved voice quality, higher data rates, and lower costs.

"A satellite system may inadvertently receive interference from another system (terrestrial or satellite) that is authorized to use the same frequencies. This can have a detrimental impact on the quality of service and capacity," explained Dr. Karabinis, who serves as senior vice president and chief technical officer at MSV. "However, interference tends to be directional; that is, it arrives at a specific angle relative to a desired signal. Exploiting this principle, the patent protects novel techniques of identifying the direction of arrival of interference and responsively modifying the satellite's antenna pattern to maximally reject the interference," Dr. Karabinis added.

According to Dr. Karabinis, the techniques included in this patent not only provide increased operational protection for MSV's space-based network, but also increase capacity for MSV's ATC service without encumbering satellite operations.

MSV says it is is redefining wireless communications through its development of a hybrid satellite-terrestrial communications network, based on MSV's patented ancillary terrestrial component (ATC) technology. The company expects its next-generation network will provide seamless, transparent and ubiquitous wireless coverage of the United States and Canada to conventional handsets. MSV plans to launch two of the most powerful commercial satellites ever built that will enable this network to support communications in a variety of areas including public safety, homeland security, aviation, transportation and entertainment, by providing a platform for interoperable, user-friendly and feature-rich voice and high-speed data services.

Mobile Satellite Ventures is a joint venture between Mobile Satellite Ventures LP and Mobile Satellite Ventures (Canada) Inc. MSVLP is owned and controlled by SkyTerra Communications, Inc. (OTCBB:SKYT).

MSV's MSAT-2 satellite and MSV Canada's MSAT-1 satellite deliver mobile wireless voice and data services primarily for public safety, security, fleet management and asset tracking in the U.S. and Canada. MSV and MSV Canada are developing a hybrid satellite-terrestrial communications network, which they expect will provide seamless, transparent and ubiquitous wireless coverage of the United States and Canada to conventional handsets. MSV holds the first FCC license to provide hybrid satellite-terrestrial services.

MSV and MSV Canada plan to launch two satellites for coverage of the United States and Canada, which are expected to be among the largest and most powerful commercial satellites ever built. When completed, the network is expected to support communications in a variety of areas including public safety, homeland security, aviation, transportation and entertainment, by providing a platform for interoperable, user-friendly and feature-rich voice and high-speed data services.
