Nokia will showcase LTE Advanced and LTE-Advanced Pro innovations at Mobile World Congress 2016 that substantially improve the capacity of both TD-LTE and FDD-LTE networks. The demonstrations include industry firsts with 3D Beamforming and 8x4 Intelligent Beamforming, unique inter-site carrier aggregation capabilities, and carrier aggregation combined with advanced modulation to triple uplink data rates.
The solutions help operators support more users without having to deploy additional base stations, and improve the customer experience by increasing throughput across a cell's coverage area. The innovations are largely driven by software developments, which will work on current base stations as well as with advanced cloud-based configurations. Speedy and more reliable mobile broadband helps operators to drive up revenue, reduce churn and opens up new business opportunities with enterprises.
LTE-Advanced and LTE-Advanced Pro enhancements
TD-LTE-Advanced Pro 3D Beamforming demonstration shows Nokia's Intelligent Beamforming capability that maximizes 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 8x4 (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.
Nokia has demonstrated a record throughput of 4.1 Gbps by running LTE-Advanced Pro TDD-FDD LTE Carrier Aggregation on commercial Flexi Multiradio 10 Base Stations with China Mobile and Ooredoo. This speed record remains unbeaten.
Following the successful acquisition of Alcatel-Lucent, the new Nokia is LTE and TD-LTE radio network supplier to the world's 15 largest 4G operators, and the combined market leader in TD-LTE based on Dell'Oro Q3 report, 2015.
