NTIA Report TR-96-331Radio Propagation Considerations for Local Multipoint Distribution SystemsAugust 1996Roger A. Dalke, George A. Hufford, and Ronald L. Ketchum |
|
|
Abstract: A local multipoint distribution system will essentially broadcast television signals (and perhaps more) to subscribers in small cells. It has been proposed to put such systems in the frequency band from 27.5 to 29.5 GHz where the wave length is only about 1 cm, and where equipment is not well established and propagation effects are not entirely known. In this report we discuss what is known about the expected behavior of the radio waves and we suggest areas that need more study. |
Keywords: atmospheric absorption; LMDS; millimeter waves; power budgets; rain attenuation; television |
