Noisy neighbors can be very annoying! I am not talking about social problems here, but the issue of intercell interference between adjacent network cells. It’s a common problem, with interference at the boundary between nearby cells causing low throughput and a poor mobile broadband experience.
To meet smartphone users’ seemingly insatiable appetite for high-speed data, operators are increasingly looking to TD-LTE to increase capacity. A key technology deployed by TD-LTE is multiple antennas, like beamforming, which can deliver a great subscriber experience in many scenarios. However, this is not always the case at the cell boundaries where signals from one beam can interfere with devices being served by a neighboring cell.
Here’s a simple diagram to illustrate what can happen:
Enter NSN’s just-launched Intelligent Beamforming technology – which coordinates with multiple cells to produce a beam that is actually aware of potential interference and can eliminate it.
To see Intelligent Beamforming in action on our commercial Flexi Multiradio 10 Base Station, check out this demonstration video:
Beamforming has already been proven in multiple deployments and NSN’s Intelligent Beamforming is a continuation of our multiple antenna technology software innovations for our Flexi Multiradio 10 Base Station. Not only can this solution lead to double cell edge gains in most cases, but it also improves overall system throughput by up to 50%.
The benefits are many. NSN’s Intelligent Beamforming enhances network capacity and gives a better customer experience. It also cuts costs by reducing the need for new sites. The solution gives the best results when used with a large number of antennas and channel reciprocity.
With Intelligent Beamforming, annoying ‘noisy neighbors’ can now be a thing of the past.
