ctrum that is used intermittently is that of news broadcasters that have rights to particular spectrum that they use irregularly for remote broadcasts of special events (for example, crime scenes, fires) to which they dispatch specially equipped trucks to record and transmit the broadcasts back to the stations. Shared Spectrum Company has spent ten years developing its unique shared- spectrum access software. The Defense Advanced Research Projects Agency (DARPA), which is part of the Department of Defense, funded the research with $25 million in seed capital. The major challenge in developing its dynamic-spectrum access software was in distinguishing the many types of emissions from those of wireless transmissions. It is necessary to distinguish false positives such as background noise and engine noises (including those in automobiles) from wireless signals. An additional challenge was developing the peer-to-peer technology that enables all of the devices in a network to be synchronized together and continuously monitor the network. Synchronization is required for the devices to operate together on the same spectrum. DARPA underwrote the research for military purposes. The intent is to take advan- tage of existing wireless networks in countries where the military is deployed SO that its communications are up and running faster and at lower cost than setting up its own infrastructure. The military currently uses Shared Spectrum Company's software for mobile devices carried by soldiers. The software automatically tunes radios to avail- able frequencies rather than using spectrum analyzers to manually tune a soldier's wireless device. Shared Spectrum Company CEO Tom Stroup envisions its software being used for a wide variety of commercial applications. Its current emphasis is on cellular appli- cations because of the demand for more data and video services. It's working with a major supplier to put its technology on femtocells (small cell sites for inside buildings) for access to multiple frequency bands. Applicatio
