E. Reporting Results
It is important to make a comprehensive survey report that records test results and provides useful information for the
engineer who actually install the equipment. The following information should be included in the survey report (see
Survey Template):
z A description of the site, explaining which buildings and grounds are to be included in the report. A description of
the topography of outdoor areas may be useful.
z A specification of the construction of the buildings and construction materials.
z Determine the customer requirements for;
9 the number of wireless terminals
9 required coverage
9 performance requirements (traffic density, grade of service, etc.)
z The location of the GDK-20W System.
z Cabling details. Include a specification of cables already present on the site and a list of new cabling required.
Include the distance between a base station and a WTIB for existing and new cabling.
z Copies of the maps of the site with the positions of base stations and the cell boundaries. Different cell boundaries
can be marked with different patterns to avoid confusion, i.e. dotted, dashed, dot dash, etc. Do not use colors as
these may be lost when photocopying.
Use the following numbering conventions:
xwyy refers to the identity of the base station, where;
x is the level (-1 is basement, 0 is ground floor, 1 is 1st floor, etc.)
w is the base station number.
yy is the base station position number. This number should be unique.
xcyy refers to the identity of the cell, where;
x is the level at which the measurement was made. (-1 is basement, 0 is ground floor, 1 is 1st floor, etc.)
c is the cell number.
yy is the base station position number that is being measured.
