Nokia has announced that it will demonstrate LTE Advanced and LTE-Advanced Pro innovations at Mobile World Congress 2016. The innovations are crucial as it is supposed to substantially improve the capacity of both TD-LTE and FDD-LTE networks. Nokia said the innovations will allow operators to 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 demonstrations proposed at MWC 2016 include industry firsts with 3D Beamforming and 8×4 Intelligent Beamforming, unique inter-site carrier aggregation capabilities, and carrier aggregation combined with advanced modulation to triple uplink data rates.
TD-LTE-Advanced Pro 3D Beamforming promises 4-fold uplink and 3-fold downlink throughput gains, measured in outdoor field environments using a commercial base station and devices, said Nokia. The company’s Intelligent Beamforming technology, meanwhile, now includes 8×4 (8 transmit and 4 receive antennas) capability for TD-LTE that doubles cell edge rates and delivers 50 percent more average sector throughput.
Nokia added that its Inter-Site Carrier Aggregation combines TDD and FDD carriers from different base stations located at different sites to provide high throughput at the cell edge using existing Release 10 devices. 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, said the company.
Nokia said the innovations will serve to significantly improve the capacity of TD-LTE and FDD-LTE networks. The company previously 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.
Jeongho Kang, VP, NW Technology Division at LG Uplus, said: “Korea is the world’s most advanced mobile broadband market and we continually strive to satisfy our customers’ demands for the highest throughput and reliable connectivity. Creating more network capacity is vital to achieve that aim. LTE-Advanced Pro is an important development and we have showcased our readiness to leverage powerful new capabilities such as 3D beamforming that can help us to meet our goals.”
Tero Peltola, head of FDD and TDD LTE Product Management at Nokia, said: “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.”
