Resumen del manual
Access to high speed data allows first responders to have a virtual “desktop in the field” and enhance communications among first responders in the field and remote emergency response coordinators. This accurate, up-to-date information can help save lives and minimize additional risks to the public. Because CDMA is a standardized, widely available commercial technology, the solution leverages the economies of scale of existing 3G networks and allows full interop erability between public safety broadband and commercial 3G wireless networks. As commercial CDMA networks evolve to 4G, the Alcatel- Lucent Broadband 700 MHz solution will be capable of implementing the same improved capabilities. 2 Alcatel-Lucent Broadband 700 MHz Solution for Public Safety Going Beyond Narrowband Limits — To Meet Public Safety Needs Broadband CDMA solutions supple ment and enhance land mobile radio (LMR) networks with advanced multimedia capabilities. Arming first responders with advanced multimedia services allows them instant access to mission-critical data, giving local, state and even federal agencies the ability to exchange information across jurisdictional boundaries. Wide area public safety wireless communications today use LMR technologies such as P25. Because of the small size of the radio channels used by these technologies, these networks are unable to support data-intensive applications such as video, e-mail with attachments and web access to agency databases. The urgent need for effective, capable, interoperable emergency response services has been powerfully demonstrated in recent major disas ters, such as Hurricane Katrina and the destruction of the World Trade Center towers on September 11, 2001. Today, organizations respon sible for public safety and security must be prepared to meet escalating challenges at the local, state and federal level, while operating within tight budgets. Constraints of existing public safety networks The wireless technology that currently supports public safety significantly lags behind commercial developments. Land mobile radio technologies support primarily: • Push-to-talk group voice • Textual applications such as text-based messaging Proprietary land mobile radio solutions and weak standards significantly impede voice interoperability. Alcatel-Lucent Broadband 700 MHz Solution for Public Safety Innovative Capabilities that Leverage Existing Land Mobile Radio Transmission Towers The Alcatel-Lucent Broadband 700 MHz solution represents a quantum leap in first responder communication. Based on open-standard, commercial CDMA2000® 1xEV-DO Revision A (EV-DO Rev A) broadband technol ogy, the Alcatel-Lucent solution provides transmission rates up to 3.1 Mb/s and coverage radius of 18 miles per site and higher. This performance dramatically exceeds the limited-range public safety solutions deployed in the 4.9 GHz public safety band, which typically have a range of 300 yards or less. Broadband technology is deployed as an overlay to existing LMR networks. Because of the long ranges achieved by the technology, existing LMR transmission towers can be reused, eliminating the high costs associated with new tower construction. Delivering cutting-edge data and Fast, easy communication users beyond the range of their multimedia capabilities enables key across jurisdictions and systems home public safety network can still personnel to communicate faster and more effectively in emergency situations, no matter where they’re In times of emergency, the ability to communicate seamlessly with all key resources is critical.

Because CDMA technology uses standardized protocols and interfaces, In addition, the Alcatel-Lucent solution enables rapid deployment of additional capacity on portable plat forms, such as a command center, as needed, when fixed infrastructure is not available to handle an emergency. 4 Alcatel-Lucent Broadband 700 MHz Solution for Public Safety More powerful information tools By using CDMA technology, the Alcatel-Lucent solution can support a growing spectrum of advanced com munication capabilities that create a “desktop in the field” — and enhance day-to-day, task force and mutual-aid response. These voice, video, text and data capabilities include: • Streaming video (surveillance, remote monitoring) • Broadcast (multicast) audio or video sent simultaneously to multiple handsets • Digital imaging • Aut...
