چکیده
The ITU Radiocommunication Assembly, considering a) that many new short-range (operating range less than 1 km) personal communication applications are being developed which will operate indoors; b) that there is a high demand for radio local area networks (RLANs) and wireless private business exchanges (WPBXs) as demonstrated by existing products and intense research activities; c) that it is desirable to establish RLAN standards which are compatible with both wireless and wired communications; d) that short-range systems using very low power have many advantages for providing services in the mobile and personal environment; e) that knowledge of the propagation characteristics within buildings and the interference arising from multiple users in the same area is critical to the efficient design of systems; f) that there is a need both for general (i.e. site-independent) models and advice for initial system planning and interference assessment, and for deterministic (or site-specific) models for some detailed evaluations, noting a) that Recommendation ITU-R P.1411 provides guidance on outdoor short-range propagation over the frequency range 300 MHz to 100 GHz, and should be consulted for those situations where both indoor and outdoor conditions exist, recommends 1 that the information and methods in Annex 1 be adopted for the assessment of the propagation characteristics of indoor radio systems between 900 MHz and 100 GHz.

متن کاملPropagation Prediction Method Development in Support of International Spectrum Management
With the growth of wireless technology for an everincreasing range of devices, services, applications and users, the role of spectrum management is becoming more complex and difficult. National and international spectrum regulations define the use of frequencies from 9 kHz to 275 GHz, and most spectrum bands are allocated to two or more services. Furthermore, new technologies and growing techno...
