Slashdot: Qualcomm Doubles 5G mmWave Range To 2.36 Miles For Broadband Modems

Qualcomm Doubles 5G mmWave Range To 2.36 Miles For Broadband Modems
Published on September 01, 2020 at 04:50AM
As 5G networks have continued to spread across the world, the biggest issue with ultra-fast millimeter wave (mmWave) towers has been their short transmission distance, which is generally measured in city blocks rather than miles. Today, Qualcomm announced a breakthrough in mmWave transmission range, successfully achieving a 5G data connection over a 3.8-kilometer (2.36-mile) distance -- over twice the range originally promised by its long-range QTM527 antenna system last year. VentureBeat reports: It's important to put today's news into perspective, as the record is specific to broadband modems rather than smartphones. Qualcomm is touting the achievement as evidence of mmWave's viability as a fixed wireless access solution, enabling carriers to offer fiber-speed 5G coverage in rural, suburban, and urban communities that might have had poor wired home broadband options in the past. The successful test was conducted in Regional Victoria, Australia, presumably with minimal physical interference between the sending and receiving devices. The test relied on two existing Qualcomm hardware solutions -- the Snapdragon X55 modem and QTM527 antenna -- inside a consumer premises equipment broadband modem, communicating with Ericsson's Air5121 and Baseband 6630 tower hardware, enhanced by extended-range software. No details were provided on speeds or other details of the connection, but Qualcomm characterized the successful range test as "the first step in utilizing mmWave for an extended-range 5G data transfer," hinting that there may have been compromises in speed or other areas. The company previously noted that carriers would be able to deliver up to 7Gbps download speeds if the QTM527 could access a full 800MHz of mmWave spectrum. Existing tower hardware has hit 4.3Gbps for a single device or 8.5Gbps for two devices.

Slashdot: AT&T Now Lets Customers Lock Down Account To Prevent SIM Swapping Attacks

AT&T Now Lets Customers Lock Down Account To Prevent SIM Swapping Attacks Published on July 02, 2025 at 01:30AM AT&T has launched a new Account Lock feature designed to protect customers from SIM swapping attacks. The security tool, available through the myAT&T app, prevents unauthorized changes to customer accounts including phone number transfers, SIM card changes, billing information updates, device upgrades, and modifications to authorized users. SIM swapping attacks occur when criminals obtain a victim's phone number through social engineering techniques, then intercept messages and calls to access two-factor authentication codes for sensitive accounts. The attacks have become increasingly common in recent years. AT&T began gradually rolling out Account Lock earlier this year, joining T-Mobile, Verizon, and Google Fi, which already offer similar fraud prevention features. Read more of this story at Slashdot.

Slashdot: Protecting 'Funko' Brand, AI-Powered 'BrandShield' Knocks Itch.io Offline After Questionable Registrar Communications

Protecting 'Funko' Brand, AI-Powered 'BrandShield' Knocks Itch.io Offline After Questionable Registrar Communications Published on December 16, 2024 at 01:04AM Launched in 2013, itch.io lets users host and sell indie video games online — now offering more than 200,000 — as well as other digital content like music and comics. But then someone uploaded a page based on a major videogame title, according to Game Rant. And somehow this provoked a series of overreactions and missteps that eventually knocked all of itch.io offline for several hours... The page was about the first release from game developer 10:10 — their game Funko Fusion, which features characters in the style of Funko's long-running pop-culture bobbleheads. As a major brand, Funko monitors the web with a "brand protection" partner (named BrandShield). Interestingly, BrandShield's SaaS product "leverages AI-driven online brand protection," according to their site, to "detect...

Slashdot: Wells Fargo CEO Says More Job Cuts Coming at the Bank as AI Prompts 'Efficiency'

Wells Fargo CEO Says More Job Cuts Coming at the Bank as AI Prompts 'Efficiency' Published on December 11, 2025 at 12:15AM Wells Fargo expects more job cuts and higher severance costs in this quarter that ends in three weeks, bank CEO and President Charlie Scharf said Tuesday at an investors conference in New York. He's also betting on AI to drive efficiency and, eventually, further workforce reduction.From a report: "As we've gone through the budgeting process, and even pre AI, we do expect to have less people as we go into next year," Scharf said at the Goldman Sachs Financial Services Conference in New York City. "We'll likely have more severance in the fourth quarter." The fourth quarter runs Oct. 1 through Dec. 31 for the San Francisco-basaed bank. Wells Fargo already has shrunk from 275,000 employees to about 210,000 since Scharf joined the bank in 2019 -- about a 24% decrease. Its largest employee base remains in Charlotte, with about 27...
