Behind every wireless telecommunications decision is a prediction of how far the signal will travel and how much strength it will lose along the way. This is called propagation modelling. Propagation models drive decisions about things like how and where to deploy cell towers, what rules to establish for geographically sharing spectrum, and what kind of spectrum equipment to build. It is vital that all stakeholders trust the models being used and accept the results as sound.

This month, NTIA’s Institute for Telecommunication Sciences (ITS), the nation’s spectrum and communications lab, released a new official code base for the Irregular Terrain Model (ITM) for use by experts and non-experts alike.

The Federal Communications Commission Report and Order opening the 6 GHz band to Wi-Fi and other unlicensed uses requires that ITM be used by the automated frequency coordination  system designed to protect incumbents from commercial entrants. Under the Commission’s ruling, at specific distances ITM must be used with an appropriate clutter model as one of the factors when determining exclusion zones to protect incumbent services.

NTIA’s 2020 Spectrum Policy Symposium showcased how private-sector innovation and government support are working to advance America’s longtime leadership in wireless technologies. The third annual symposium, held virtually on September 22, brought together a broad cross-section of government policymakers and experts in the telecommunications, tech, space and aerospace industries. It featured keynote remarks from U.S. Secretary of Commerce Wilbur Ross, White House Office of Science and Technology (OSTP) Director Kelvin Droegemeier, and Acting NTIA Administrator Adam Candeub.

NTIA’s BroadbandUSA program has added a new digital inclusion section to its website.  This webpage compiles resources and program information from federal agencies as well as state and local governments that are working across the country to close gaps in broadband adoption and use, affordability, access to devices, and digital skills.  NTIA is particularly pleased to announce this resource during Digital Inclusion Week.

This new online resource reflects BroadbandUSA’s efforts to promote digital inclusion through technical assistance, webinars, federal partnerships, and the BroadbandUSA Digital Inclusion Leaders Network (DILN) – a cohort of local and state government practitioners who share priorities and best practices.  The digital inclusion webpage includes a Federal Resource list containing information about digital inclusion programs, publications, and data to complement the federal funding information in the BroadbandUSA Federal Funding Guide.

This summer, NTIA reported initial results from our latest NTIA Internet Use Survey, which showed that Americans were increasingly using a larger and more varied range of devices. But with dozens of topics covered in the survey, there is a lot more we can learn from this data collection, including questions about online activities such as checking email, watching videos and participating in the sharing economy.

Two online activities of particular importance right now are remote work and taking online classes. Our data show that approximately 51 million Americans reported using the Internet to work remotely in 2019, nearly a third of the estimated 160 million Americans who were employed in November. A smaller number, about 43 million Americans, said they used the Internet to take classes or complete job training last year. That represents about 20 percent of Internet users ages 15 or older.

Although our survey was conducted in November 2019, a few months before the outbreak of the coronavirus, the results can be helpful to understanding the extent to which Americans were prepared to work and learn online.

Working Remotely

On September 22, NTIA will virtually host its annual Spectrum Policy Symposium. The Symposium will bring together experts from academia, private industry, and government to tackle the nation’s most pressing spectrum management challenges.    

The Symposium is preceded by significant spectrum progress at NTIA and the Trump administration. In August, the White House announced the availability of an additional 100 MHz of spectrum following an NTIA 3450-3550 MHz band repurposing study. NTIA research is exploring potential repurposing in the 3100-3450 MHz band and has also helped lead to the current Citizens Broadband Radio Service (CBRS) band auction.

Admission is free and open to the public via the NTIA website. For additional information or questions, email spectrumsymposium@ntia.doc.gov.

For decades, NTIA’s research laboratory, the Institute for Telecommunication Sciences (ITS), has been working alongside the National Institute of Standards and Technology’s (NIST) Public Safety Communications Research program (PSCR) and the public safety community to enhance mission-critical communications. First, it was all about intelligible voice communications. But first responders now have access to equipment and networks that support video and image transmission as well.

Streaming video could help an incident commander coordinate firefighters, for example. However, the challenge is that fire response is fast—about 3 minutes for a single-family dwelling. Deploying and coordinating helmet-cam feeds from 25 firefighters will only be practical with the aid of computer vision and video analytics, which are currently just out of reach.

Today’s off-the-shelf cameras come with many image-quality problems. Think of a door’s peep hole: you look through it and see a backlit person or just the arm of someone standing too far to the side. It would be great to have something between you and the peephole that fixes these problems.

The Trump Administration has engaged in significant efforts to ensure that the U.S. leads the world in 5G, which promises to be an essential driver of our economy for years to come. This month, building on technical analysis by NTIA engineers, the Administration announced that an additional 100 megahertz of mid-band spectrum would be made available for 5G deployment.

For more than 25 years, NTIA has been surveying the American public about its computer and Internet use, in partnership with the Census Bureau.

Our most recent NTIA Internet Use Survey went into the field in November 2019, with more than 50 questions administered to approximately 50,000 households across the United States. The survey covers a range of topics related to digital inclusion and similar issues, with the goal of informing Internet policy analysis and development that can help to bridge the digital divide.

In anticipation of conducting future surveys, NTIA is seeking recommendations from the public about how we can improve our survey and make it as relevant as possible. Are there questions we previously asked that should be changed or deleted? Are there any questions that we should be adding? We want to hear from you.

After digesting your comments, NTIA will draft a revised survey instrument to use in the future. Beginning this fall, experts from the Census Bureau will conduct cognitive testing of our draft survey, which will help us learn what questions may cause confusion or elicit inaccurate responses. Census will recommend changes aimed at addressing any problems uncovered during this process.

The Trump administration has made substantial progress in improving the resilience of the Internet ecosystem and reducing the threat of botnets. In a report released today, the Departments of Commerce and Homeland Security documented more than 50 activities led by industry and government that demonstrate progress in the drive to counter botnet threats. Building upon work started two years ago with the Botnet Report and Road Map, industry and government are working hard to put a stop to these dangerous attacks.

Here are a few of the milestone achievements:

NTIA launched the Minority Broadband Initiative (MBI) in November 2019 in partnership with Historically Black Colleges and Universities (HBCUs) and Tribal Colleges and Universities (TCUs) to work on solving deployment challenges in vulnerable communities.  As part of that ongoing effort, BroadbandUSA’s July webinar, “Cyberinfrastructure: Moving Beyond Broadband at HBCUs and TCUs,” highlighted that cyberinfrastructure – the broader network of technology systems – is a vital component for HBCUs and TCUs to remain competitive in the digital economy. The webinar was moderated by NTIA’s MBI lead, Francine Alkisswani, and Tonya Smith-Jackson, Senior Vice Provost for Academic Affairs at North Carolina A&T State University.

Curtis Bradlee, Acting Chief Information Officer at South Carolina State University, said partnerships with area universities helped to expand SC State’s capabilities. Among these partnerships is C-Light, a statewide direct fiber network managed by Clemson University that provides access to national and international research networks such as Internet2. SC State serves as an access point for other institutions to connect to Internet2, and participated in the National Science Foundation (NSF) CI Empower initiative.
