Radio observations of the cosmos are gathered by geoscientists using complex earth-orbiting satellites and ground-based equipment, and by radio astronomers using large ground-based radio telescopes. Signals from natural radio emissions are extremely weak, and the equipment used to measure them is becoming ever-more sophisticated and sensitive.
The radio spectrum is also being used by radiating, or "active," services, ranging from aircraft radars to rapidly expanding consumer services such as cellular telephones and wireless internet. These valuable active services transmit radio waves and thereby potentially interfere with the receive-only, or "passive," scientific services. Transmitters for the active services create an artificial "electronic fog" which can cause confusion, and, in severe cases, totally blinds the passive receivers.
Both the active and the passive services are increasing their use of the spectrum, and so the potential for interference, already strong, is also increasing. This book addresses the tension between the active services' demand for greater spectrum use and the passive users' need for quiet spectrum. The included recommendations provide a pathway for putting in place the regulatory mechanisms and associated supporting research activities necessary to meet the demands of both users.

Store description
With 3 stores less than 1 hour outside the DC/Metropolitan area (1 in Gaithersburg, 1 in Frederick and 1 in Hagerstown, MD), we have the largest selection of books in the tri-state area. Wonder Book and Video has been in business since 1980 and online since 1997. We have over 1 Million books for sale on our website and another 1 Million books for sale in our 3 locations. Items on Abe are not necessarily in stock at our retail locations. Please do not call the stores to place orders for Abe Books sales. We have a very active online inventory and as such, we can receive multiple orders for the same item. We fill those orders on a first come first serve basis, but will refund promptly any items that are out of stock. Since 1980 it has always been about the books. ALL kinds of books from 95 cent children's paperbacks to five figure rare and collectibles. A merging of the old and new is where we started, and it is where we are today. Our retail stores have always been places where a reader can rush in looking for a title needed for a term paper that is due the next day, or where bibliophiles can get lost "in the stacks" for as long as they wish. In 2002 USAToday recognized us as "1 of 10 Great Old Bookstores", and we have been featured in numerous other newspaper and TV stories including Washington Post and CSpan. Members ABAA, ILAB.…
