BEIJING -- Nokia Networks and China Telecom today announced the world-first FDD-TDD carrier aggregation including a user device chipset. In the demonstration by China Telecom, Nokia’s LTE base station achieved interoperability with a commercial user chipset developed by Marvell. This successful interoperability is a milestone toward commercial adoption of the carrier aggregation to significantly improve the LTE network speed and coverage for LTE users in areas where both variants of LTE are deployed.
A stable peak download speed of 260 Mbps was achieved in the carrier aggregation demonstration with FDD 20 MHz in 1.8 GHz and TDD 20 MHz in 2.6 GHz spectrum. For the total speed, FDD spectrum contributed to 150 Mbps while TDD spectrum contributed to 110 Mbps.
The successful interoperability of Nokia’s LTE base station with a user device chipset means the FDD-TDD carrier aggregation is rapidly getting closer to real deployment for the benefits of LTE users. This accomplishment is very significant for China Telecom as it can utilize its FDD band 3 for improving LTE coverage, and TDD band 41 for improving throughput and capacity for the best possible LTE service experience. Carrier aggregation will allow the operator to optimally use the scarce spectrum resources while providing the best LTE service experience.
The 'gleaming city on a hill,' Steve Saunders calls it. But who is going to take us from today's NFV componentry to the grand future of a self-driving network? Here's a look at the vendors hoping to make it happen.
With the mobile ecosystem becoming increasingly vulnerable to security threats, AdaptiveMobile has laid out some of the key considerations for the wireless community.
Understanding the full experience of women in technology requires starting at the collegiate level (or sooner) and studying the technologies women are involved with, company cultures they're part of and personal experiences of individuals.
During this WiC radio show, we will talk with Nicole Engelbert, the director of Research & Analysis for Ovum Technology and a 23-year telecom industry veteran, about her experiences and perspectives on women in tech. Engelbert covers infrastructure, applications and industries for Ovum, but she is also involved in the research firm's higher education team and has helped colleges and universities globally leverage technology as a strategy for improving recruitment, retention and graduation performance.
She will share her unique insight into the collegiate level, where women pursuing engineering and STEM-related degrees is dwindling. Engelbert will also reveal new, original Ovum research on the topics of artificial intelligence, the Internet of Things, security and augmented reality, as well as discuss what each of those technologies might mean for women in our field. As always, we'll also leave plenty of time to answer all your questions live on the air and chat board.
