HUNTSVILLE, Ala. -- ADTRAN, Inc. (NASDAQ:ADTN), a leading provider of next-generation networking solutions, today announced an industry first that will eliminate several key barriers service providers face when expanding broadband service deployments. Frequency Division Vectoring (FDV) enhances the capabilities of both G.fast and VDSL2 vectoring by enabling them to better coexist by working in tandem across a single subscriber line in the service provider’s network. This new patent-pending technology enables service providers to take immediate advantage of the maximum G.fast performance without the expense of transitioning an entire subscriber base from VDSL2 to G.fast technology. Preserving investments in Fiber-to-the-Cabinet (FTTC) infrastructure, FDV doubles data rates and increases the reach of intermediate-rate services – between 100 Mbps to 1 Gbps – allowing the delivery of cost-effective premium broadband to 80% more subscribers.

“While G.fast and VDSL2 have always been seen as complementary technologies, the limitations of G.fast have been exposed when forced to operate in a VDSL2-compatible mode at higher rates,” said Jeff Heynen, principal analyst, broadband access and pay TV, Infonetics. “As service providers look to build out their G.fast adoption strategies, ADTRAN’s FDV technology has a key performance impact by allowing G.fast and vectored VDSL2 technologies to work in concert to boost performance. Service providers can now maximize a broader market opportunity without wasting unused bandwidth in their networks or prematurely forcing subscribers served by 100Mbps VDSL2 to move to G.fast.”

FDV expands the addressable market for G.fast by broadening its applicability from Fiber-to-the-Building (FTTB) and Fiber-to-the-distribution points (FTTdp) out to existing street cabinet sites. This allows service providers to fortify recent cabinet investments while mitigating the operational challenges that currently exist regarding providing power to new FTTdp deployments. FDV strengthens the value proposition of G.fast by substantially improving deployment economics and enabling faster service time to market for game-changing broadband services rates.

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.
