       DRAFT NEW RESOLUTION ON RADIOWAVE PROPAGATION STUDIES
              FOR SYSTEM DESIGN AND SERVICE PLANNING



     Following discussions on the above subject at the meeting of
Study Group Chairmen and Vice-Chairmen, 29-30 November 1994, a
draft new Resolution is presented in Annex 1 for consideration and
comment by the RAG.


Annex:  1
                                 
                                 
                                 
                              ANNEX 1
                                 
                                 
                       DRAFT NEW RESOLUTION
                                 
          RADIOWAVE PROPAGATION STUDIES FOR SYSTEM DESIGN
                       AND SERVICE PLANNING

[The ITU Radiocommunication Assembly,]
     
     considering

a)   that ITU-R Study Group 3 has the task of taking account
of the characteristics and variability of radiowave
propagation and of advising on prediction procedures suitable
for use in service planning and performance evaluation;

b)   that since propagation characteristics depend on
geographical location, climate, local environment and
atmospheric variability, the development of propagation
prediction procedures by Study Group 3 relies, inter alia, on
the availability of measurement data and the maintenance of
calibrated databanks;

c)   that the acquisition of measurement data, and their
subsequent use by Study Group 3 in the development and
improvement of prediction procedures, is a medium- to long-
term process,
     
     recognizing

a)   that the service Study Groups often have short-term
needs for information for new systems and networks;

b)   that, when designing such systems, relevant propagation
data are sometimes submitted directly to the Study Group
concerned;

c)   that these data, whilst fulfilling a particular short-
term need, may be of limited value in other circumstances and
may require further analysis prior to their use in studies on
propagation prediction method development for other
applications,
     
     resolves

1    that, whenever possible, Study Group 3 should be
consulted on the most appropriate propagation information for
each purpose that arises, where a current Recommendation may
not seem to be wholly applicable;

2    that all input contributions to other Study Groups which
contain propagation information should be referred to Study
Group 3, so that, in addition to the value of the
contribution to the work of the other Study Group, the
information may also be used in the future work of Study
Group 3;

3    that the series of Questions now assigned to Study Group
3 should be examined by the service Study Groups to identify
where additional study topics are required.
