Here's some excellent news: Comcast has upgraded Xfinity Internet speeds for more than 20 million customers, including hundreds of thousands of Southeast Texas customers, for no additional cost.

Xfinity Internet tiers, and the NOW branded prepaid products, will now benefit from 50 to 100 percent faster upload speeds, helping customers upload large files in a flash when working from home or post videos to social media in seconds. Download speeds will also increase for most internet tiers.

Customers can view the details of their current internet plan by going to the Account, Your Plan section in the Xfinity app. While there, customers can also test their internet speed.

As the demand for connectivity continues to skyrocket in hyper-connected households, the new speed increases will provide even faster download and upload speeds to ensure customers can do more of what they love online — stream, game, chat, surf, and more — on all their devices, all at the same time.

“We want and need seamless connectivity for everything,” says Jose Espinel, Comcast Texas’ regional senior vice president. “Our faster download and upload speeds, combined with our world-class WiFi equipment, ultra-low-lag internet experience, and WiFi PowerBoost that delivers speeds up to a gig, are providing a converged connectivity experience that we believe is unmatched in the industry.”

With 94 percent of devices connecting to the internet via WiFi, fast speeds are only as good as the WiFi that connects them. At home, Xfinity’s WiFi gateways and extenders create a fast, reliable, and secure connection to every corner of the house. Outside of the home, Comcast’s Xfinity internet customers have access to the nation’s largest network of WiFi hotspots to connect on the go.

In addition to faster speeds, new and existing Xfinity Internet customers can now get a line of Unlimited on Xfinity Mobile included for a year when they subscribe to a 400 Mbps or faster plan.

And with WiFi PowerBoost, Xfinity Mobile and Comcast Business Mobile customers seamlessly receive WiFi speeds up to 1 Gbps no matter what internet speed tier they subscribe to, in and out of the home, on the nation’s largest and fastest WiFi network.

Fast download and upload speeds are an important feature of a comprehensive connectivity experience that delivers incredible benefits to consumers, including:

  • Reliability: Xfinity has greater than 99 percent reliability, and the Xfinity network utilizes artificial intelligence to keep customers connected by fixing issues before customers even know they happened.
  • Ultra-low-lag: Comcast recently introduced the first customers in the world to a pioneering new feature of Xfinity Internet that dramatically reduces latency when using interactive applications like gaming, videoconferencing, and virtual reality. Customers will have less delay and a smoother, more responsive end-to-end online experience.
  • Great WiFi in and out of the home: Next-generation Xfinity gateways deliver advanced WiFi capacity to power hundreds of devices in homes, and more than a billion devices each year across Comcast’s network. WiFi PowerBoost delivers Xfinity Mobile customers speeds up to 1 Gbps over WiFi at home or at millions of WiFi hotspots across the country.
  • Digital security: xFi Advanced Security, included free for customers who lease an Xfinity gateway, protects connected devices from malware and other threats at the gateway before they reach connected household devices. Since launching xFi Advanced Security, Xfinity has stopped more than 10 billion cyber security threats.

Customers can take advantage of the unlimited mobile line offer via their account on Xfinity.com, in the Xfinity app, or by calling 1-800-XFINITY.

Houston researchers develop material to boost AI speed and cut energy use

ai research

A team of researchers at the University of Houston has developed an innovative thin-film material that they believe will make AI devices faster and more energy efficient.

AI data centers consume massive amounts of electricity and use large cooling systems to operate, adding a strain on overall energy consumption.

“AI has made our energy needs explode,” Alamgir Karim, Dow Chair and Welch Foundation Professor at the William A. Brookshire Department of Chemical and Biomolecular Engineering at UH, explained in a news release. “Many AI data centers employ vast cooling systems that consume large amounts of electricity to keep the thousands of servers with integrated circuit chips running optimally at low temperatures to maintain high data processing speed, have shorter response time and extend chip lifetime.”

In a report recently published in ACS Nano, Karim and a team of researchers introduced a specialized two-dimensional thin film dielectric, or electric insulator. The film, which does not store electricity, could be used to replace traditional, heat-generating components in integrated circuit chips, which are essential hardware powering AI.

The thinner film material aims to reduce the significant energy cost and heat produced by the high-performance computing necessary for AI.

Karim and his former doctoral student, Maninderjeet Singh, used Nobel prize-winning organic framework materials to develop the film. Singh, now a postdoctoral researcher at Columbia University, developed the materials during his doctoral training at UH, along with Devin Shaffer, a UH professor of civil engineering, and doctoral student Erin Schroeder.

Their study shows that dielectrics with high permittivity (high-k) store more electrical energy and dissipate more energy as heat than those with low-k materials. Karim focused on low-k materials made from light elements, like carbon, that would allow chips to run cooler and faster.

The team then created new materials with carbon and other light elements, forming covalently bonded sheetlike films with highly porous crystalline structures using a process known as synthetic interfacial polymerization. Then they studied their electronic properties and applications in devices.

According to the report, the film was suitable for high-voltage, high-power devices while maintaining thermal stability at elevated operating temperatures.

“These next-generation materials are expected to boost the performance of AI and conventional electronics devices significantly,” Singh added in the release.

Texas falls to bottom of national list for AI-related job openings

jobs report

For all the hoopla over AI in the American workforce, Texas’ share of AI-related job openings falls short of every state except Pennsylvania and Florida.

A study by Unit4, a provider of cloud-based enterprise resource planning (ERP) software for businesses, puts Texas at No. 49 among the states with the highest share of AI-focused jobs. Just 9.39 percent of Texas job postings examined by Unit4 mentioned AI.

Behind Texas are No. 49 Pennsylvania (9.24 percent of jobs related to AI) and No. 50 Florida (9.04 percent). One spot ahead of Texas, at No. 47, is California (9.56 percent).

Unit4 notes that Texas’ and Florida’s low rankings show “AI hiring concentration isn’t necessarily tied to population size or GDP.”

“For years, California, Texas, and New York dominated tech hiring, but that’s changing fast. High living costs, remote work culture, and the democratization of AI tools mean smaller states can now compete,” Unit4 spokesperson Mark Baars said in a release.

The No. 1 state is Wyoming, where 20.38 percent of job openings were related to AI. The Cowboy State was followed by Vermont at No. 2 (20.34 percent) and Rhode Island at No. 3 (19.74 percent).

“A company in Wyoming can hire an AI engineer from anywhere, and startups in Vermont can build powerful AI systems without being based in Silicon Valley,” Baars added.

The study analyzed LinkedIn job postings across all 50 states to determine which ones were leading in AI employment. Unit4 came up with percentages by dividing the total number of job postings in a state by the total number of AI-related job postings.

Experts suggest that while states like Texas, California and Florida “have a vast number of total job postings, the sheer volume of non-AI jobs dilutes their AI concentration ratio,” according to Unit4. “Moreover, many major tech firms headquartered in California are outsourcing AI roles to smaller, more affordable markets, creating a redistribution of AI employment opportunities.”
