Nokia is preparing to showcase 3D Beamforming, 8×4 Intelligent Beamforming, and carrier aggregation combined with advance modulation at this month’s Mobile World Congress in Barcelona. The technologies offer the potential to substantially increase the capacity of both TD-LTE and FDD-LTE networks.
Some highlights:
- TD-LTE-Advanced Pro 3D Beamforming uses Nokia’s Intelligent Beamforming capability to maximize signal levels while also minimizing inter-cell interference by combining vertical and horizontal beamforming. It promises 4-fold uplink and 3-fold downlink throughput gains, measured in outdoor field environments using a commercial base station and devices .
- Nokia’s unique Inter-Site Carrier Aggregation combines TDD and FDD carriers from different base stations located at different sites. This can provide high throughput at the cell edge using existing Release 10 devices.
- Nokia Intelligent Beamforming now includes 8×4 (8 transmit and 4 receive antennas) capability for TD-LTE that doubles cell edge rates and delivers 50% more average sector throughput. It also implements DL-CoMP (Coordinated MultiPoint) for a 50% increase in cell edge spectral efficiency. The Intelligent Beamforming capabilities are particularly useful with high bands for greater coverage and capacity.
- Uplink Carrier Aggregation and 64QAM modulation are introduced via software and combined to increase peak data rates in FDD-LTE cells by up to 150 Mbps, three times the maximum uplink speed of typical LTE networks today. This rebalances users’ uplink and downlink experiences, following multiple downlink speed increases in LTE-Advanced in recent years.
“In addition to providing the most high-performing FDD-LTE and TD-LTE networks today, Nokia is also rapidly developing LTE-Advanced Pro technologies with operators. Nokia’s 3D Beamforming, for downlink and uplink, is an early innovation and has been field tested in Hangzhou, China. We are also responding to the need for more capacity by enabling comprehensive aggregation of TDD and FDD LTE networks. With Nokia, operators can be assured that our solutions are field-proven and future-proof,” stated Tero Peltola, head of FDD and TDD LTE Product Management at Nokia.
