Cellvine Presents Advanced Cellular Coverage Technology for Public Safety Networks.

Smart Connectivity Solutions Ensure that First Responders and Emergency Services Remain in Constant Radio Contact In Any Urban or Rural Environment

BALTIMORE -- Cellvine, a leading developer and provider of coverage enhancement solutions for cellular networks, unveiled its comprehensive coverage solution set for Public Safety Networks, enabling all emergency services to maintain constant contact during routine or crisis operations. Cellvine will be displaying its solutions at the APCO 2007 Conference, Baltimore Convention Center, Maryland, 6-9 August, in Booth #D524.

The critical factor for any emergency service provider is the ability to maintain constant contact throughout all operations - preserving the chain of command, passing timely information throughout the network and re-defining tasks to reflect dynamic situations during crises. Cellvine's comprehensive cellular and radio coverage solution set for in-building, outdoor and wide-area environments provides a clear communications tunnel for first responders and key emergency service personnel, connecting the deepest in-building environments with the outside world, to enhance safety and efficiency at all times.

Cellvine provides coverage enhancement solutions in all the Public Safety / Homeland Security Radio Spectrum; VHF, UHF, SMR/700/800/900 and NPSPAC. Air Interface technologies include Analog and Digital Trunked Radio and iDEN[R]; and Cellvine's technology allows encryption to be handled without alteration. Cellvine has also recently added TDD capability to provide coverage solutions for mobile Broad Band Data delivery to First Responders.

Cellvine has also created a unique Air-Borne Repeater System to build out its emergency response capabilities. This System allows First Responders to maintain radio coverage in the face of natural disaster or terrorist strike. An HBFS[R] Repeater is deployed inside a helicopter or other aircraft. Wirelessly coupled with a far distant unaffected Base Station, it enables radio communications in an area that previously experienced total cellular or radio blackout.

"Following disasters such as the events of 9/11, tremendous emphasis has been placed on improving communications among emergency service personnel and between operations headquarters and personnel in the field for quicker and more efficient operations during crises," commented Yoni Shiff, CEO at Cellvine. "Our coverage enhancement solutions, including our recently introduced SDAS[R] Smart Distributed Antenna System for large building complexes, provides a seamless and continuous communications corridor for all emergency services, ensuring that control centers can maintain contact with their personnel in the field, even during mass call events, greatly improving response times, maximizing efficiency and saving more lives. We are working in several large cities in the United States and around the world to deploy our solutions and ensure that mission-critical communications can be maintained at all times."

SDAS[R] is an Off-Air or Base Station fed sophisticated RF over thin low cost coaxial cable distribution system. Its primary application is providing In-Building or Subterranean radio coverage. SDAS[R] balances and controls the output power and sensitivity of each individual service antenna to gain optimal coverage, noise immunity, coverage control and radiation control. Its ease of deployment, ease of expansion, full system remote monitoring and control and relatively lower cost compared with Fiber based systems makes it an ideal candidate for any In-Building or Campus scenario, enhancing public safety and providing a critical channel of communication for emergency response teams.

Cellvine has developed a broad range of cellular coverage enhancement products and solutions based on its patent-protected technology for improving cellular signals in over-ground and subterranean environments. The company has enriched its coverage solutions with comprehensive management capabilities, providing operators with full real-time control of their coverage networks without the need for costly infrastructure replacement.
