Can You Program a Radio to Dominate
the Spectrum?
-- New DARPA challenge is looking for innovative approaches
to adaptive, software-based radio communications
Radios are used for a wide range of tasks, from the
most mundane to the most critical of communications, from garage door openers to military operations. As the use of
wireless technology proliferates, radios and communication devices often compete with, interfere with, and disrupt
the operations of other devices. DARPA seeks innovative approaches that ensure robust communications in such congested
and contested environments.
The DARPA Spectrum Challenge is a competition for teams to create software-defined
radio protocols that best use communication channels in the presence of other users and interfering signals.
Using a standardized radio hardware platform, the team that finds the best strategies for guaranteeing successful
communication in the presence of other competing radios will win. In addition to bragging rights for the winning teams,
one team could win as much as $150,000.
High priority radios in the military and civilian sectors must be able
to operate regardless of the ambient electromagnetic environment, to avoid disruption of communications and potential
loss of life. Rapid response operations, such as disaster relief, further motivate the desire for multiple radio networks
to effectively share the spectrum without requiring direct coordination or spectrum preplanning. Consequently, the
need to provide robust communications in the presence of interfering signals is of great importance.
“The Spectrum
Challenge is focused on developing new techniques for assured communications in dynamic environments – a necessity
for military and first responder missions. We have created a head-to-head competition to see who can transmit a set
of data from one radio to another the most effectively and efficiently while being bombarded by interference and competing
signals,” said Dr. Yiftach Eisenberg, DARPA program manager. “To win this competition teams will need to develop new
algorithms for software-defined radios at universities, small businesses and even on their home computers.”
Registration for the Spectrum Challenge is expected to officially open in January 2013. Any U.S. academic institution,
business, or individual, is eligible to compete, with certain restrictions. More information and additional details
can be found at

Challenge website.
