A “hybrid” application is characterised as one where the stationary battery is continuously charged and discharged in a controlled cycle, working in parallel with another power source. A typical example would be a 12 hour cycle, where both the load is supplied and the battery is recharged by a generator, followed by 12 hours without generator power, where the battery supplies the load. In this application, cyclic control is required to ensure that the battery achieves its 12 hour discharge, and is fully recharged by the generator in 12 hours, ready for the next discharge.

As wireless telecommunication services continue to expand, wireless providers are deploying more and more base station antennas in order to meet the growing demand. As a result, antenna towers and support structures are being pushed to the limits of their load capacity. It is therefore important for wireless service providers and tower owners to understand the impact that each base station antenna has on the overall tower load.
