A New Zealand operator had to provide good quality indoor coverage during an event at a busy convention center.
First, they tried a conventional solution using a COW with a standard panel antenna.
The results were far from satisfactory.
The optimizing team them tried solving the problem by mounting a VEGA CC-12 HP dual band very high gain narrow beam antenna on a nearby building aimed at the center.
Look at the walk tests below and see how this unconventional solution solved a very conventional problem.
