Last week, we hosted the first webinar in our mobility lab series “CBRS Neutral Host Network using Multiple Operator Core Network.” In case you missed it, you can read about the webinar in this blog or scroll down for the links to the video and Q&A. Background: CableLabs Mobility Lab Webinar Series The FCC established […]

The CableLabs wireless R&D group has a charter to investigate new and emerging wireless technologies that will benefit our cable operator members, half of which also own mobile networks. As cable and mobile networks continue to converge, we’ve built a fully functional mobility lab. The aim of the mobility lab is to conduct validation, proof of […]

Today, many people view Wi-Fi as an essential component in their home. However, people routinely experience connectivity issues because networks aren’t capable of broadcasting their Internet signal adequately and uniformly throughout their home or business. CableLabs is working with the Wi-Fi Alliance (WFA), and its new EasyMesh™ certification program, to solve this problem and provide extended, uniform coverage throughout your […]

It’s been nearly a year since the Mobile Backhaul vendor and operator team that I lead started working on techniques to improve DOCSIS® technology to provide better backhaul for mobile. One of the team’s main and most pressing issues was to solve the problem of how to provide precision synchronization and timing. Today, I am […]

The term Wi-Fi, coined by the Wi-Fi Alliance, is one of the most widely used and recognized technology terms in the world. That’s understandable when you consider facts like these: KPCBs Mary Meeker, in her highly regarded annual global internet survey, found worldwide Wi-Fi networks grew from 90 million in 2012 to 450 million in […]

Wireless communication growth has been on the rise, reaching newer industry segments such as the automotive and health industries. Each segment served by the wireless industry has different requirements, some needing ultra-high bandwidth while some requiring exceedingly low latency. With future wireless cellular Internet of Things (IoT) applications like 5G, Narrow-Band IoT (NB-IoT) and machine-to-machine […]

How many times have you been enjoying an HD video in your home and right at the most thrilling point, the movie stops and throws you into endless buffering hell? Or, maybe you’re working from home, on an important Skype call with an overseas client, and your connection drops 2 or 3 times because your […]

As the small cell densification wave is becoming a reality, mobile operators are faced with the complex task of searching for suitable backhaul solutions. This is where the hybrid fiber coaxial (HFC) networks rise up to the challenge. DOCSIS networks provide three main elements critical to backhaul solutions; location, power and capacity. Mobile operators are […]

CableLabs is excited about the publication of the Wi-Fi Multi Access Point (AP) Specification draft by Wi-Fi Alliance®. With the release of this draft specification, the Wi-Fi industry is moving towards greater interoperability and coordination between APs from different vendors. The Wi-Fi Multi Access Point (AP) Specification defines the control protocol, as well as the […]

You can find the background information for this article in the post “Sharing Bandwidth: Cyclic Prefix Elimination.”  Most wireless transmissions use a modulation technology called OFDM (orthogonal frequency-division multiplexing). This method was invented by Saltzburg and Chen at Bell Labs in the 1960s, but was not widely commercialized until the 1990s when faster signal processing […]
