Multi-band combiner

The addition of a Multi-band combiner to your collection of communication tools is an excellent way to improve signal coverage and accelerate deployment at the same time. In this article, we'll take a look at a few different models so that you can make an informed decision about which one is best for you.


Cross-band combiners speed up deployment

It has been demonstrated that increasing the uplink SNR of a small cell base station by employing a cross-band combining scheme can result in a factor three increase in the uplink power of the station. In order to accomplish this, signals from multiple Radio Units are combined in a coherent manner (RUs). It is also important to note that the relative cost of employing a cross-band combining scheme is low because the signal source is not physically located at the base station. This is something that should be taken into consideration.

A battery of tests was carried out in order to test how successful the previously mentioned architecture actually was. The experiments covered a range of three frequency bands, from 900 MHz all the way down to 800 MHz. The outcomes of the tests were analyzed and contrasted with the functionality of a conventional BTS. The results of the measurements showed a significant decrease in both the outage probability and the average SNR when compared to the results obtained from the BTS. In addition, the measurements demonstrated that the utilization of a two-stage HU-combiner was the best course of action.

The utilization of a two-stage HU-combiner resulted in the most impressive performance that could have been achieved. The HU-Power Combiner proved to be a useful tool in the fight against both familiar and unfamiliar interference. In addition to this, it was the most effective method for lowering the processing requirements of a DAS system. A multi-band combining strategy could be carried out in the most financially prudent manner by utilizing the HU-combiner.
