Recommendation on Channel Propagation Model for Local Multipoint Distribution Service
نویسندگان
چکیده
Abstract We recommend a flexible channel propagation model, which includes no more than three taps and has flexible tap gains and tap delays. The tap gains have a progressive decrease relationship, while the tap delays have a progressive increase one. The model is valid under the following assumptions: (1) there is line-of-sight propagation, (2) highly directional antennas are used at least at the receive; (3) heavy-rain attenuation effects are not taken into account, and (4) a –20 dB threshold is applied, which excludes multi-path components with amplitudes below the threshold. The available radio channel measurements support the model.

Classification of Statistical Channel Models for Local Multipoint Distribution Service Using Antenna Height and Directivity
Abstract The antenna height and directivity are used in the classification of statistical channel models for local multipoint distribution service (LMDS). When directional antennas are used and the antennas are sufficiently high providing a line-of-sight (LOS) propagation path between the transmitter and receiver, the statistics of the radio channel can be described by the lognormal or Nakagami...
متن کاملFormulation of Multiple Diffraction by Trees and Buildings for Radio Propagation Predictions for Local Multipoint Distribution Service
National Institute of Standards and Technology, Gaithersburg, MD 20899-0001 This paper presents a closed-form expression for multiple forward diffraction by rows of tree canopies and buildings applicable to the propagation predictions at centimeter and millimeter wavelengths for local multipoint distribution service (LMDS). The expression is derived from the uniform geometrical theory of diffra...
متن کاملPropagation of Radiowave for Lmds Systems
The design, planning and deployment of LMDS (Local Multipoint Distribution Service) systems require a good understanding of radio wave propagation. After a presentation of the different propagation mechanisms , we present the propagation channel characteristics: attenuation, variability and frequency selectivity due to multi-path; the selectivity being defined from wideband parameters such as d...
متن کاملImprovement of Metropolitan Wireless Networking Using Wireless Optical Mesh Networks
Many wireless networking systems were established to manipulate metropolitan networks in order to provide internet, voice, data, video and TV services in large cities. Two major systems were used for such services; Local Multipoint Distribution Service (LMDS) and Multi-channel Multipoint Distribution Service (MMDS). Both of these systems are fixed broadband access networks and both have problem...
متن کاملReliable Group Communication in ATM Networks
Upcoming applications have demanding communication needs. One requirement is the provision of a reliable high performance multipoint communication service. If a reliable service in ATM networks is based on traditional transport protocols like TCP, severe performance degradations may be observed. Additional problems occur for the provision of a reliable multipoint service, where errors occur mor...
