Three VEGA antennas mounted on a single tower can cover remote sub-urban blind-spots without causing interference to the other heavily populated and well covered areas.
Subscribers to a leading cellular provider in Irkutsk, Russia experienced several “blind spots” with poor or no service in areas isolated from the central populated areas.
The solution was to add on the tower three new sectors coupled with very high gain, very narrow beam VEGA antennas aimed at the problematic areas. The coverage simulation shown in picture (2) shows the positive impact of the solution.
This easy to implement, low cost solution solved the problem without adding interference to the already well covered populated areas. Other solutions discussed would have entailed erecting and maintaining more BTS with the accompanying cost and heavy mutual interferences issues with low QOS in the existing and newly covered areas.
