Competition to enable full-duplex links for cable increased this week when Intel Capital threw its weight behind startup GenXComm, a chip-maker looking to open up operators' entire spectrum for 5G, mobile and cable networks.
Intel Capital was one of several new and existing investors that poured $7 million into the one-year-old vendor; the money will be used to extend GenxComm's research and development team, reported Light Reading's Dan Jones.
Full-duplex communications enables one node to both send and receive data simultaneously via the same channel, thereby doubling a telecommunications' system.
"GenXComm's robust simultaneous self-interference cancellation (S-SIX) technology unleashes the full potential of the spectrum used for today's 5G mobile, WiFi and cable networks by allowing channels to be stacked one next to the other with no empty spectrum between them," a GenXComm spokesperson told Light Reading. The startup is developing a chip for analog cancellation that will empower operators to fully maximize their available spectrum.
And over the past five years, Kumu Networks developed, and then tested, full-duplex small cells. After trials with TIM last year in Italy, Kumu now says its full-duplex relay is read for the market and the vendor is miniaturizing the technology to fit on a chip, RCR Wireless wrote.
"[GenXComm is] developing an optical chip (optical delays) for analog cancellation," Joel Brand, VP of product management at Kumu, told Light Reading. "Such [a] solution has very limited market applicability and that's why they are going after the cable infrastructure side (Remote PHY) while Kumu is going after the many millions of CPE devices -- including cable modems, WiFi APs and LTE femtocells."
In a flurry of activity throughout the week, Donald (DJ) LaVoy, Deputy Under Secretary for Rural Development at the US Department of Agriculture, and his team spent about $145.8 million in the non-urban or suburban areas of seven states.
Calix reported revenue of $120.19 million – up 4% – in Q4 2019, putting a bounce in the step of company president and CEO Carl Russo and a shine to Calix's ongoing transition from hardware vendor to a provider of platforms enabled by cloud, APIs and subscriber experience.
Looking to curtail e-waste and improve the bottom line, BT will require customers to return routers and set-top boxes, although subscribers will not have to pay a fee when they receive regular broadband equipment.
Deploying DOCSIS 3.1 across its entire footprint gave Rogers Communications the ability to offer speeds of up to 1 Gbit/s,
contributing to a broadband segement that generated about 60% of the Canadian operator's $3.05 billion (US) in Q4 cable earnings.
Over the next two years, approximately 60% of service providers (both large and small) will adopt virtualization on a wide scale across their networks, according to the latest survey report from Ovum. Why are providers making these moves? Is there an easy way to start?
Learn how and why service providers are using virtualization to transform their networks. This webinar will look at how providers are leveraging virtualization to create more flexible and agile networks while also providing a better customer experience. Expert speakers from netElastic and Heavy Reading will address the industry drivers for network virtualization, the benefits that can be realized, the challenges to face and the results of virtualization being achieved by providers today.
Key topics will include:
Current network infrastructure and the move to virtualization
Benefits and challenges of network virtualization
How providers can get started
Service provider success stories: the decision to virtualize, the solution, and results
