More about Datacasting
Unlike data services available from wireless mobile broadband operators which are unicast (i.e., a separate connection to each receiver), datacasting content is broadcast to every receiver within the station’s broadcast footprint. Datacasting can transmit any kind of digital content – alert messages, images, audio, computer files, and even video. Datacasting content can be encrypted and targeted to specific intended receivers of the content, or permissioned to allow receipt by all users.
Unlike existing public safety and broadband networks, which focus on voice, the SpectraRep network is data-centric, allowing for distribution of video and other bandwidth intensive content. The primary advantages of this approach are many, including:
- The spectrum is not pre-emptible by the public or any other users.
- It represents an alternative communications path to the existing cellular system which cannot easily handle large files and video and provides redundancy in times of emergency when the cellular systems become over-taxed and do not function.
- It improves interoperability and the ability to share critical files and videos between agencies and metropolitan regions.
- Utilizing unused spectrum capacity, it does not interfere with the existing broadcasting service and is covertly sent to authorized computers within the large coverage area of the station.
- Communications can be targeted and encrypted allowing reception by selected individuals or groups, and it utilizes existing operating infrastructure thereby minimizing capital expenditure requirements and the time to deploy.
DHS Science & Technology Pilot Project
- Shakeout Earthquake Preparedness in Knoxville, TN – The Tennessee National Guard held a training exercise to drill for response to a major earthquake that takes out power and commercial networks. Datacasting for data and amateur radio for voice were assumed to be the only operational wireless networks.
- Earthquake Preparedness in Birmingham, AL – DHS S&T utilized datacasting in another earthquake preparedness exercise involving a sports stadium collapse. When other networks were compromised because of lack of power, infrastructure failure or congestion, datacasting would still be able to deliver video, files, alerts and other data.
- School Safety in Ft. Wayne, IN – DHS S&T conducted a school shooter exercise in a rural part of Indiana outside of Ft. Wayne. LTE coverage was spotty, LMR did not work inside the school. We improved access to school security cameras and then delivering that and other response information to multiple responding agencies.
- Public Facilities in Salt Lake City, UT – DHS S&T conducted an event in Salt Lake City oriented around improving information sharing between public buildings and responders. We worked with the sports stadium, convention center and a major shopping district to grant access to private video during emergencies.
- Federal Law Enforcement Training Center Georgia – FLETC trains all of the federal law enforcement at every federal agency including TSA, CBP, ICE, ATF, US Marshalls, Air Marshalls and more. We worked with FLETC to improve access to video on base.
