US : A world leading 3G mobile operator has increased its network capacity by fifty percent. A trial was conducted by Quintel with a leading tier one 3G Mobile operator to see if Quintel’s SVP ( Sectorization in the Vertical Plane ) technology could help reduce the amount of call barring and increase 3G network capacity.
On completion of a 10 week trial network capacity had increased by fifty percent and call barring was eliminated. It should be noted that no extra antennas, 3G frequency spectrum or base stations were added to the 3G network.
3G networks all over the world are facing 3G network capacity issues as 3G mobile broadband becomes more popular, but one factor many 3G operators did not predict was the rapid rise of 3G smartphones which gobble up huge 3G data bandwidth.
Quintel's trial results and their findings, coupled with the excellent performance increase experienced by the Tier 1 3G mobile operator provides an opportunity to level 3G voice and data network requirements to meet current demands. The diagram above is explained at foot of article.
Therefore by implementing Quintel’s Sectorization in the Vertical Plane (SVP) solution, spectrum and antenna-limited sites were able to consistently increase capacity while eliminating call blocking.
SVP is an innovative solution to sectorization that was developed by Quintel to more effectively use existing RF spectrum by adding sectors vertically, as opposed to horizontally. This approach increases capacity and improves the customer experience. Unlike current solutions, SVP requires no additional spectrum, horizontal antenna sector positions or cell sites to add capacity in 3G networks.
In dense urban areas, SVP also improves coverage and capacity into tall buildings while minimizing interference. SVP provides greater spectral efficiencies resulting in increased capacity, significantly improved network quality and enhanced coverage.
Case study background
A tier one 3G operator is delivering high-end services and, therefore, needs to mitigate spectrum limitations quickly and at the lowest cost to meet demand.
In some areas, the network was experiencing both capacity constraints and call blocking, and there were no immediate plans for clearing spectrum to add carriers or new sites. Quintel conducted an analysis, and recommended SVP.
Diagram explanantion : SVP adds a cell sector split in the vertical plane, producing an “overlayed” sector and an “underlayed” or smaller sector topology in the congested UMTS original sector.
