Dispatch Radio Service

To direct and redirect your fleet reliably, Mobile Satellite Ventures Dispatch Radio Service offers two-way voice dispatch or one-way voice broadcast service. It's a cost-efficient alternative to land-based radio communications systems.

Not only can you implement the service almost overnight, you don't have to build and maintain your own private network, which minimizes capital costs and eliminates network support costs altogether.

The MSV network acts much the same as a radio tower, turning the entire continent into a single cell and transmitting signals to and receiving signals from subscribers on the ground. Dispatch Radio Service can also be configured to provide extra security to your subscribers.

Customize your communication with talkgroups

Dispatch Radio Service relies on establishing talk groups - sets of users who share a common radio channel. Each MSAT terminal can support up to 15 talk groups. While users can belong to more than one talk group, each talk group can include as many as 10,000 members. When establishing talk groups, priority levels can be predetermined in order to define who will be permitted to listen and speak during each session.

Users also have the ability to dial-in to a talk group from the PSTN or dial-out from a talk group to the PSTN.

Dispatch Radio Service features and benefits:

• Priority 1 interrupt - in emergencies, a user can override other users within the same talk group. You can set a talk group to one of three different priority levels, which allows users to filter out conferences on low-priority talk groups unless that talk group is selected. High-priority talk group conferences are always heard no matter which talk group is selected.
• Network flexibility – MSAT Terminals can be interfaced with existing terrestrial fleet communications infrastructures.
• Interoperability – talk groups can be configured to allow for interagency communications between local, regional, and national emergency response organizations.
• Coverage Adaptability – the footprint allows subscribers to expand or reduce dispatch radio coverage as their needs change.
• Network reliability – Satellite networks perform during emergencies when land-based communications are not available.
• Secure Communications – the network employs the IMBE (Improved Multi-Band Excitation) voice codec approved by the Association of Public Safety Communications. Digital coding and scrambling prevents casual eavesdropping or monitoring of calls.

Mobile Satellite Ventures MSAT G2 hardware Dispatch Radio Service can help people in numerous industries and occupations do their jobs more effectively:

• Homeland Security

Mobile Satellite Ventures Engages Boeing To Develop Next Generation Satellites

Boeing to Construct the World's Most Powerful Transparency Class Satellites to Blanket the Western Hemisphere

Reston, Va., January 11, 2006

Reston, Va. - January 11, 2006 – Mobile Satellite Ventures (MSV) and Boeing (NYSE:BA) today announced that they have entered into a contract for the construction and delivery of three next generation L-band satellites. These satellites, among the most powerful commercial satellites ever built, will form the backbone of an advanced commercial telecommunications network being developed by MSV and its Canadian joint venture partner, MSV Canada.

The network will be based on MSV’s patented Ancillary Terrestrial Component (ATC) technology, which combines the best of satellite and cellular technology. It will deliver reliable, advanced and ubiquitous voice and data coverage throughout North and South America.

“The agreement with Boeing solidifies our commitment to building a ubiquitous network that provides seamless coverage to our end users in North and South America. We are excited at the prospect of completing this paradigm-shifting project ahead of schedule and to provide improved service in both rural and urban areas, eliminating the telecommunications divide,” said Alexander H. Good, Vice Chairman and CEO of MSV. “Boeing is an excellent partner for our next stage of development. Their 40-year heritage in the satellite industry and vast experience in the mobile satellite arena, brings with it a wealth of experience and reliability that will prove invaluable in the construction of our next generation satellites.”

“MSV is creating a critical communications asset representing a huge step forward for mobile satellite services,” said Howard Chambers, Vice President of Boeing Space & Intelligence Systems. “In addition to providing mobile service to users in the most remote regions, Boeing technology deployed by MSV will keep lines of communication open for first responders in times of natural disasters. Our focus on building powerful and highly complex satellites will deliver instantaneous access and mobility anywhere on the continent.”

Building upon proven and reliable technology from predecessor satellites, including the powerful Boeing 702 infrastructure, the satellites will be among the largest and most powerful commercial satellites ever built. Each satellite’s primary antenna will be almost 75 feet across, about twice as large as any previous commercial satellite. In addition to covering the Americas with hundreds of spot beams, the satellites will use MSV’s patented ATC technology to deliver service to wireless devices that are virtually identical to cell phone handsets in terms of aesthetics, cost and functionality.

With ATC, the satellites work in tandem with terrestrial based stations that provide coverage and capacity in urban areas where satellite signals are frequently blocked. The contract with Boeing also provides for the delivery of the related ground based beam forming system and other ground design elements, to provide the most advanced beam forming flexibility and interference cancellation unprecedented in commercial satellite systems. These technological advances will allow MSV optimal deployment of its ATC technology and spectrum utilization.

“This agreement for the construction of the state of the art L-band system marks the beginning of an exciting new era for mobile communications in Canada and the United States,” said Larry J. Boisvert, Chairman of MSV Canada. “It demonstrates the commitment of MSV and MSV Canada to bring the most advanced wireless services to the regions of the western hemisphere.”

The contract provides for the delivery of MSV-1 and MSV-2, which will replace and expand upon the current MSAT satellite system operated by MSV and MSV Canada. Like the MSAT satellites, the MSV-1 and MSV-2 satellites will cover Canada, the United States, including Alaska, Hawaii, Puerto Rico, the Virgin Islands, and the Caribbean Basin, as well as Mexico. The third satellite, MSV-SA will introduce MSV’s advanced communications services into South America.

Boeing will build the spacecraft bus infrastructure, based on the world’s most powerful satellite – the Boeing 702. It will supply 11,000 Watts of power through 5-panel solar array wings using highly efficient triple-junction Gallium arsenide cells. Boeing will build upon a quarter-century heritage of integrating and deploying L-band technology. The 22 meter L-band reflector for mobile terminal links will complement a 1.5 meter Ku-band antenna.

The spacecraft will also be equipped with a qualified digital channelizer that maximizes spectrum allocation. With the constellation of MSV-1, MSV-2, and MSV-SA, Boeing will provide the technology that will enable MSV to offer their customers advanced mobile services using small, handheld terminals interoperable with terrestrial terminals.

The signing of this contract kicks off, ahead of schedule, the regulatory construction milestone requirements for the satellites. The satellites are expected to be launched in 2009 and 2010.
