Reliability Prediction Methods for Tower Top Electronic Systems
The purpose of this white paper is to remove some of the mystery of how reliability and especially failure rates are determined. Prediction methods are described and examples of how they are used for Tower Top electronic systems are given. These methods include using underlying physics of failure, empirical results from customer returns and accelerated tests to determine failure rates.

Fiber
to the Antenna: Current Trends and Installation Best
Practices
Until now, no standard procedures for installing fiber
on the tower existed. This paper offers a set
of researched best practices that can help mobile service
providers, tower construction contractors and tower
hands install FTTA architectures correctly and efficiently.

Predicting Tower Top Electronic Systems Reliability
Through Accelerated Testing
This paper discusses several
physical models of degradation mechanisms that can occur
for electronics situated in adverse environments, such
as the tops of cellular towers, and explains how those
models can be tapped to create reliability testing specifically
aimed at defending electronics against those failure
modes.
