FCW : June 30, 2015
HOW IT WORKS 22 June 30, 2015 FCW.COM consider its global reach and user base. The departments of Homeland Securi- ty and State, for example, are just two of the many U.S. government entities with a global presence. Harmonizing our accessibility standards with the European standard would ensure that our outposts abroad are outfitted with ICT infrastructure and services that are fully compatible with local accessibility requirements. As our world becomes more con- nected, a universal standard is not only sensible but efficient. In fact, current law and Office of Management and Bud- get rulemaking support the adoption of such standards. The National Technology Transfer and Advancement Act of 1995 and revised OMB Circular A-119 mandate the incorporation of voluntary consen- sus standards as domestic standards where possible. The use of consensus standards in place of unique standards, unless ille- gal or impractical, makes maintaining those standards easier for public-sector CIOs and federal government employ- ees while also making it easier for users with disabilities to access information. A call to action The harmonization of the U.S. proposed rule and the European standard would greatly benefit those who need better ICT accessibility. As the U.S. Access Board’s proposed rule moves into a review stage, it is critical that federal CIOs and citizens alike support accessi- bility for all by calling for much-needed global harmony. With updates to its proposed rule, the U.S. Access Board could facilitate the creation of a global accessibility stan- dard, thereby ensuring that government employees, people with disabilities and others all over the world can have com- puting experiences free of barriers and limitations. The harmonization of standards cre- ates an opportunity for everyone. Most important, it benefits users with disabili- ties who need and deserve accessible technology. n Karen S. Evans is national director of the U.S. Cyber Challenge, a nation- wide talent search and skills develop- ment program focused on the cyber workforce. She served as administra- tor for e-government and IT at the Office of Management and Budget under President George W. Bush. The government is eager to make more federal spectrum available on the com- mercial market to fuel the explosion of data-hungry mobile broadband apps and services. But moving government spectrum to market can be a slog. A recent auction of 65 MHz of prime spectrum fetched about $45 billion for federal coffers, but getting the military to agree to vacate most of the highly desirable paired frequency sets (which have uplink and downlink bands) took the better part of a decade and required a lot of political arm twisting. The concept of sharing spectrum is almost as old as radio. The 1912 Radio Act, passed in the wake of the Titanic’s sinking, required private telegraph oper- ators at busy seaports to stay off the air for the first 15 minutes of each hour to give naval and other military stations exclusive use of the airwaves. One hundred years later, the Federal Communications Commission created rules for Medical Body Area Networks, which give health care facilities access to a 30 MHz swath of spectrum and reserve 10 MHz for the operation of wireless medical information devices in the home. To reduce the chances for interfer- ence, the MBAN spectrum operates on the ground at very low power and shares frequencies with airborne mobile telemetry systems, which operate in the air at very high power. In 2015, the FCC approved rules for sharing spectrum in the 3.5 GHz band. The plan allows for incumbent federal users, mostly ship-borne radar systems, to maintain their first rights while cre- ating two other tiers for licensed and unlicensed users. That approach could be characterized as “cooperative sharing,” said Peter Ten- hula, deputy associate administrator for spectrum management at the National Telecommunications and Information Administration, which manages federal spectrum holdings. “The devices are working with each other or are controlled by a centralized database and sharing information,” he added. A working database is essential for dynamically allocating frequencies and maintaining protocols for user priority. Currently, narrow bands of unlicensed spectrum between licensed TV chan- nels — known as “white spaces” — are allocated by use of an FCC database. Dynamic spectrum access for the 3.5 GHz band would allocate as much as 150 MHz of spectrum in real time based on demand and priority. As the government tries to get more spectrum to commercial users, sharing has some intriguing possibilities for agencies. For federal users, “the goal is to make sure that there’s no need to displace equipment that is still within its useful life,” Tenhula told FCW. Additionally, as large swaths of spec- trum open up, there is the potential for agencies to gain access to new frequen- cies as new regulatory thinking allows for a blurring of the lines between fed- eral and non-federal users. n A short history of spectrum sharing BY ADAM MAZMANIAN 0630fcw_012-025.indd 22 6/10/15 9:40 AM
