Spectrum, the broadband brand operated by Charter Communications, unveiled a live demonstration of next-generation Wi-Fi technology this week, showing peak throughput of nearly 10 gigabits per second to a single device.
The showcase, conducted with semiconductor giant Broadcom, was presented at SCTE TechExpo25 in Washington, D.C., inside the NCTA booth on the convention floor. It will be available for viewing throughout the duration of the event.
The demonstration combined the full 6 GHz band with 125 MHz of spectrum in the 7.125–7.25 GHz band, enabling wireless speeds that previously required wired connections. According to Spectrum, the setup allowed for four 320 MHz channels or two 640 MHz channels, producing the kind of speed, capacity, and reliability required to meet growing household and enterprise demand.
The technology could eventually allow Wi-Fi devices such as smartphones, gaming systems, augmented and virtual reality headsets, and computers to achieve speeds approaching 20 Gbps. The demonstration was presented alongside Spectrum’s Advanced Wi-Fi 7 routers, which support 320 MHz wide channels and have already won industry awards.
“This milestone highlights the power of combining Wi-Fi 7 technology with forward-looking spectrum policy,” said Justin Colwell, the Executive Vice President of Technology Strategy and Innovation for Spectrum. “Proactive spectrum decisions need to be made to both maintain America’s technological leadership and allow providers and manufacturers to keep pace with evolving and intensifying consumer demands. Together with Broadcom, we are showing what is possible when we combine the unparalleled success of 6 GHz Wi-Fi with adjacent 7 GHz unlicensed spectrum.”
The companies said the results underscore how U.S. spectrum policy directly impacts innovation and industry leadership. By authorizing additional unlicensed spectrum above 7.125 GHz, regulators could enable the United States to remain at the forefront of global connectivity while ensuring consumers and businesses are first to benefit from higher wireless performance.
Charter executives noted that Americans’ appetite for wireless data continues to grow, with more devices per household demanding reliable connectivity. High-capacity Wi-Fi is seen as critical to preventing bottlenecks as providers expand their fiber and high-speed broadband infrastructure.
“Broadcom is proud to partner with Spectrum to showcase next-gen Wi-Fi performance that matches the fastest wired broadband speeds,” said Manny Patel, the Vice President of Marketing in Broadcom’s Wireless Communications and Connectivity Division. “This demonstration underscores how additional unlicensed spectrum in the 7 GHz band is critical to enabling 10 Gigabit and beyond whole-home coverage.”
