美国国土安全部授予的支持s Development by Device Solutions, WRC, PBS North Carolina and NCDIT
北卡罗来纳州威克森林（2022年5月16日） -在这个5 g的时代,物联网和一切数字,金属氧化物半导体t fire and rescue agencies still use analog paging systems to dispatch and communicate with first responders. The need to upgrade a 70-year-old technology is dovetailing with the ongoing rollout of a new generation of television broadcast technology. A new statewide public safety system using North Carolina’s public television network is under development that could support public safety and emergency response agencies throughout the state.
无线研究中心的政府和公共安全社区倡议正在为开发一个原型数字寻呼系统的协作论坛，以使用通信网络为下一代广播电视技术，称为Paging Plus。授予工程公司设备解决方案的美国国土安全部的小型企业创新研究（SBIR）赠款通过无线研究中心，PBS北卡罗来纳州PBS（以前为UNC-TV）和N.C.信息技术部（NCDIT）支持应用研究）。
公共安全机构使用分页系统，因为它们在自然灾害和其他紧急情况下比蜂窝网络更可靠。寻呼系统基于70年历史的技术，这些技术是从911个呼叫中心广播的网络上，这些中心可以到达页要求设备。带有信息的单向调度页将发送给志愿者和人员部门的第一响应者所穿的设备。通信网络通常以县为基础进行管理，其中一两个塔楼提供边际县范围的承保范围。
电视广播信号使用高塔，建筑物和山脉上的高功率发射器和天线。这些信号的占地面积比传统的公共安全要求系统更大。Internet Technology正在将下一代电视的广播信号集成到名为ATSC 3.0的广播信号中，以及用于公共安全数据的专用渠道。PBS北卡罗来纳州提供全州范围的报道，并与资本广播公司和北卡罗来纳州格林维尔的Raleigh-Durham Market推出了下一代电视服务。北卡罗来纳州Wunk TV PBS北卡罗来纳州的Greenville地区计划在全州范围内扩展下一代电视报道。
The new digital paging capabilities would provide responders with improved pager coverage, more rapid dispatching, and overall improved situational awareness with additional information including maps and videos. New services can also enhance notifications for the public through on-screen notifications for weather, fire, earthquake, Amber Alerts and other emergencies.
WRC除了建模无线信号覆盖范围外，还可以帮助开发开发，包括天线设计，原型制作和测试。领导WRC政府和公共安全团队的高级工程师约翰·斯瓦茨（John Swartz）表示：“公共安全机构不需要建立一个新的网络来改善服务。”“现已设计了网络基础架构和新系统的新设备。对于该计划的下一阶段，WRC和项目团队将寻求商业合作伙伴，将新系统带到北卡罗来纳州及其他地区的市场。”
New devices have been developed including a stand-alone pager and software to integrate new services into smartphones. Receivers support live audio streaming, video, data files, maps, and sensor data impossible to include in conventional paging systems.
“The Paging Plus team has taken the concept much further than I ever imagined,” said WRC Senior Engineer Paul Allan Sadowski. His N.C. government career included serving as director of infrastructure planning for the NCDIT Broadband Infrastructure Office, leading the state’s First Responder Network. Sadowski is also a co-inventor for a drone communications and sensor system that can rapidly deploy long range data communications, including support for disaster response.
Sadowski is a co-inventor for Paging Plus approximately seven years ago along with Red Grasso, the current director of NCDIT’s First Responder Emerging Technologies (FirstTech) program for the State of North Carolina and former firefighter for the Town of Morrisville. More recently, Paging Plus was recognized by the National Association of Broadcasters for TV Broadcast Innovation.
“Paging Plus lays the foundation for a whole ecosystem of solutions that are better served by the unique attributes of ‘concurrent one to many’ TV broadcasting over high power, high tower transmission facilities,” Sadowski said. “Not only can Paging Plus advance first responder communications, the technology can benefit cyber protection, flight safety, K-12 education, and more robust public service information.”
“DIT’s FirstTech program is excited to continue supporting this effort on behalf of first responders,” Grasso said. “Two-way radio, cellular priority, and mobile application technologies have all taken giant leaps forward in the past several years. It is time for the paging technology to advance to something that is faster and more reliable than audible tones.”
“PBS North Carolina is excited to work with the Wireless Research Center, Device Solutions, and the North Carolina FirstTech program in this effort,” said PBS North Carolina Chief Technology Officer Fred Engel. “As a statewide public media entity, we are committed to keeping North Carolinians informed during emergencies and in times of crisis. Utilizing our network’s capabilities to improve public safety is a powerful way we can serve communities across the state.”
WRC founder and Chief Executive Officer Gerard Hayes said the Wireless Research Center was founded to foster collaboration to bridge the gap between research and commercialization that brings the next generation of products and services to market. “We are excited to be working with this team to enhance public safety with more rapid, accurate and detailed communications to first responders,” he said.
Other WRC public safety community initiatives include collaboration withThe Center of Excellence for Advanced Technology Aerial Firefighting(CoE) created by the state of Colorado to lead development and testing for aerial firefighting technology. The WRC is also collaborating with the NOAA National Severe Storms Laboratory to develop a new way to measure humidity using 4G and 5G cell signals, potentially improving public broadcast warnings for severe weather.
设备解决方案首席执行官克里斯·兰姆（Chris Lamb）表示：“设备解决方案很高兴能够处于ATSC 3.0的前沿，并与WRC合作开发了端到端的便携式解决方案，用于向急救人员进行数据铸造。”“ WRC从一开始就支持该项目，其专业知识对优化性能和了解全州RF环境至关重要。他们的支持是我们成功地与PBS北卡罗来纳州和Triveni Digital合作提供工作系统的核心。”Triveni Digital是下一个用于数据广播的代电视服务的提供商。
