HowStuffWorks How the Radio Spectrum Works All your life you have heard about "AM Radio" and "FM radio", "VHF" and "UHF" television, "Citizens Band Radio", "Short Wave radio" and so on. Have you ever wondered what all of those different names really mean? In this edition of How Stuff Works we will look at the radio spectrum and see what is really going on!
IBM Who gets the 3G spectrum? (11/01) Government's new plan for 3G spectrum is a mixed bag for wireless providers. 3G could provide us with easy access to an incredible range of new telecommunications services. In order to provide those services, however, wireless companies must be able to access a significant amount of spectrum that is currently dominated by government and other commercial interests. Technology writer Dana Triplett uncovers the latest plan from the federal government for assessing spectrum use, offering an inside look at the players in the struggle for the invisible but valuable commodity of radio frequency in the U.S.

ITU Radio-Frequency Spectrum Publications The Radiocommunication Sector acts as the coordinator in managing the usable radio-frequency spectrum efficiently, keeping it free from harmful interference, and adopts international regulations and treaties governing this use.

NATO Cooperation in Radio Frequency Management (2000) Cooperation between NATO member countries in the use of radio frequencies for defence purposes is underpinned by a common commitment to collective security and defence. The availability of radio frequencies is essential for the armed forces' operational readiness and effectiveness and the NATO-wide standardisation and coordination of frequency allocations is vital to ensure interoperability among multinational forces.
NTIA US National Spectrum Requirements: Projections and Trends The availability of radio spectrum in the United States is critical to many telecommunications services, ranging from cellular telephones to air traffic control. Although spectrum is not a consumable resource, the use of a frequency at a given location usually excludes that frequency from being used by others in the same geographic area. This need for exclusive geographic use has led to current spectrum regulations that establish exclusivity in spectrum use by granting licenses for spectrum use, and the partitioning of the spectrum for shared use between radio services.

ZDNet Overcrowded Airwaves A kind of air traffic control may be needed to manage our ever-expanding wireless communications. Wireless networking has been touted as an ideal solution for a wide range of communications problems -- synchronizing PDAs with desktop PCs, eliminating printer cables, creating in-building LANs, connecting buildings on a campus and even spanning the "last mile" -- the distance between a connected PC and telephone company or ISP. But wireless has its dark side: interference. As wireless devices proliferate, we will see more and more "midair collisions." To understand why, you need to understand the politics, economics, and technology behind today's wireless networking equipment.

IEEE An Economic Framework for Dynamic Spectrum Access and Service Pricing
The concept of dynamic spectrum access will allow the radio spectrum to be traded in a market like scenario allowing wireless service providers (WSPs) to lease chunks of spectrum on a short-term basis. Such market mechanisms will lead to competition among WSPs where they not only compete to acquire spectrum but also attract and retain users. Currently, there is little understanding on how such a dynamic trading system will operate so as to make the system feasible under economic terms.

IEEE Hybrid Wireless-Optical Broadband Access Network (WOBAN): Network Planning Using Lagrangean Relaxation
The concept of a hybrid wireless-optical broadband access network (WOBAN) is a very attractive one. This is because it may be costly in several situations to run fiber to every home (or equivalent end-user premises) from the telecom central office (CO); also, providing wireless access from the CO to every end user may not be possible because of limited spectrum. Thus, running fiber as far as possible from the CO toward the end user and then having wireless access technologies take over may be an exc...
