摘要 he 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,
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.
