Nokia Networks-China Telecom FDD-TDD Carrier Aggregation


Nokia Corporation’s (NOK) network unit Nokia Solutions and Networks (:NSN) and China Telecom have together unveiled the world’s first FDD TDD carrier aggregation that will also have an operator device chipset. China Telecom's demonstration showed Nokia's LTE base station achieved interoperability using Marvell's chipset.

In the carrier aggregation display, a constant speed of 260 Mbps was realized through TDD (Time Division Duplex) 20 MHz in 2.6 GHz and FDD (Frequency Division Duplex) 20 MHz in 1.8 GHz spectrum. For the overall speed, the contribution of FDD spectrum is 150 Mbps whereas that of TDD spectrum is 110 Mbps. The hybrid options promise better connectivity through faster Internet download speed.

Nokia further stated that to bring FDD-TDD convergence for commercial usage, the company is working with other operators.

Nokia is consistently working toward increasing its foot print in China. The company is aggressively deploying 4G LTE network across China, which should drive revenues higher in the coming quarters. Despite declining revenues across most of its geographic regions, the NSN segment registered 18% year-over-year revenue growth across Greater China. In the second quarter of 2014, Nokia’s NSN segment generated $3.5 billion in revenues, down 7.7% year over year.  

Nokia currently bears a Zacks Rank #3 (Hold).
