As U.S. and global policy makers debate the future of spectrum policy, CableLabs is releasing initial results of our Wi-Fi network use analysis, which further confirms the critical need to keep the current unlicensed spectrum resources and add more soon. In short, the 6 GHz band — the key frequency band for Wi-Fi, alongside the […]

With more and more CableLabs member operators deploying or preparing to deploy ITU-T-based passive optical networking (PON) technologies such as XGS-PON, interoperability of equipment from different vendors is more important than ever. One well-known source for the lack of cross-vendor interoperability of XGS-PON equipment stems from differing implementations of the ONU Management Control Interface (OMCI) […]

The broadband industry is only as strong as the people who power it.  At CableLabs, we believe that innovation isn’t driven by technology alone — it’s driven by the people behind it. That’s why we’re focused on strengthening the industry through three key areas: collaboration, connection and preparation. By creating environments where people can exchange […]

CableLabs is proud to partner with Broadcom, Cisco, the Wireless Broadband Alliance (WBA) and the Wi-Fi Alliance (WFA) to offer an open-source version of the Open Automated Frequency Coordination (AFC) solution. This platform enables unlicensed devices to operate as Standard Power (SP) devices within the recently opened 6GHz band. SP devices have a higher power […]

CableLabs is pleased to announce the certification of the industry’s first DOCSIS 3.1 Plus (DOCSIS 3.1+) device supporting four orthogonal frequency-division multiplexing (OFDM) channels. The certified device, developed by Vantiva, represents a key milestone in advancing broadband performance and capacity for cable operators worldwide. The DOCSIS 3.1 specifications require support for at least two OFDM […]

For most consumers, staying connected to the services they rely on every day likely requires subscriptions to two separate services: a broadband service at home and another for their mobile phone when they’re away from home. What if network operators could provide a single connectivity service that ensures their subscribers’ applications and devices would work […]
