Often, repeater system installations are not straight forward. The structure of the building, its location and the layout have to be taken into consideration. The survey has to be conducted outside, inside as well as on the roof top. Professional city installations are particularly challenging with so many cell towers concentrated in one area.
Stella Doradus offers free training to experienced installers as well as complete beginners. We have our own training courses that you can sign up for. Our step-by-step training will help installers design and install repeater systems correctly in buildings of all sizes.

Technical FAQs
I need a reliable system that won’t fail when customers want to pay.
The Stella repeater amplifies the signal from the mobile operators which is the most reliable signal available. In the unlikely event that the signal from one operator’s mast goes down, the antenna will simply receive the signal from the next mast, just as a mobile phone would do. The Stella repeater does not alter the operators’ signal. It simply brings it inside the building, and this ensures it is the most reliable system available.
What are taps? What are splitters?
Splitter: A splitter can be used to introduce a second antenna into the system. However, it adds 3.5dB of attenuation to the signal. The effect of this 3.5dB loss is to effectively shorten the cable. Stella specifies that the length of SD400 cable from the repeater to the internal antenna should be no more than 35m. However, if a 2 way splitter is introduced, the recommended length is reduced to 20m. If a 3 way splitter is used, the length is reduced again to 15m. A splitter adds the same loss, 3.5dB, to both sides of the split.
Tapper: A tapper (tap), is similar to a splitter in that it allows the cable to be split to install a second antenna. however, the loss is not equal on both sides. Instead, one side experiences a loss of 6dB, whereas the other side experiences a loss of 1.3dB. This can be useful when installing several antennas along the same cable. The taps can equalize the signal power to all the antennas, ensuring that the last antenna on the line still has enough power to be effective.
What is MIMO?
MIMO refers to Multiple Input, Multiple Output. It refers to a technology that allows the cellular signal to double or quadruple its bandwidth by utilizing multiple parallel data streams at the same time. It achieves this by using a different polarization for each stream of data. A separate antenna is needed for each stream, and the angle of each antenna must be offset from each other to align with its particular polarization. Even within just one frequency band, we can have up to 4 parallel steams of MIMO data. This is a big bandwidth enhancement.
