6.2 Mast Vibrations
This section describes the mast vibration tolerance supported by the MU and
RRU-N.
The equipment complies with the following:
IEC 721-3-4 class /4M5/
ETSI EN 300 019-1-4 class 4.1

(1) These requirement shall be used for verification of structural sustainability only, for
functional verification random vibration shall be used.
(2) ASD = Acceleration Spectral Density.
(3) The requirement belong to ’Exceptional/Safe function’ with the exemption:
performance of the RBS shall be verified as ’no loss of calls’ or ’loss of establish
radio link.
(4) The shock requirement shall be used for RBS’s mechanical and structural strength
test, and functional verification of RBSs that are allowed to be mounted on non
ground-based foundations. The random vibration requirement already cover all
possible excitations that ground-based foundation installation can be subjected to.
