N78 band 5G NR recordings

news.ycombinator.com Unknown 2025-07-18 05:08:17

In my last post about 5G NR, which was part of a series in which I analyzed the signals in a short recording of an idle srsRAN gNB, I mentioned that I had already decoded all the signals that appear in the recording, and that to move on with my 5G series I would need to make and use some more complex real world recordings next. A 5G band I’m particularly interested in is n78 (3.3 – 3.8 GHz TDD). This is being used to deploy 5G in many European countries, including Spain, as showed by this list

Wi-Fi Experts Reveal How Trump’s Budget Bill Could Slow Down Your Wi-Fi

cnet.com See Full Bio 2025-07-22 17:05:00

You won’t find the term “Wi-Fi” anywhere in the text of President Donald Trump’s One Big Beautiful Bill, but a provision authorizing the FCC to auction off spectrum could seriously impact speeds on newer Wi-Fi routers. Every wireless device, from garage door openers to baby monitors, relies on the electromagnetic spectrum to work. But that spectrum is a limited resource -- to open up capacity for one technology, you have to take it away from another. The latest generation of Wi-Fi 6E and Wi-Fi

3 Best Hall Effect Keyboards for Gamers and Serious Typists (2025)

Polling rate is likely one of the most prominently displayed details on any Hall effect keyboard, purely because the large numbers emphasize one of the most important aspects of these keyboards: Speed. Whether a keyboard has a 1,000- or 10,000-Hz polling rate, this number represents how many messages are sent from the keyboard to the PC every second. For example, a keyboard with 1,000-Hz polling will send 1000 messages every second. Most office equipment operates at 125 Hz. In high-performance g

zdnet.com Steven Vaughan-Nichols 2025-08-06 14:08:56

Francesco Carta fotografo/Getty Images I thought we'd dodged a networking bullet when the US Budget bill, aka the "One Big Beautiful Bill (BBB)," didn't include a freeze on AI regulation, which had been tied to broadband funding from the $42.5 billion Broadband Equity, Access, and Deployment (BEAD) program. However, I missed the point that the bill still includes provisions that could force the Federal Communications Commission (FCC) to auction off significant portions of the 6GHz spectrum cur

Wi-Fi in the US Could Get Worse Under Trump's New Law

wired.com Jon Brodkin 2025-08-08 10:00:00

The Federal Communications Commission has regained its authority to hold spectrum auctions and could use that power to take spectrum away from Wi-Fi networks and license it to mobile carriers AT&T, Verizon, and T-Mobile. As we previously wrote, the Senate budget bill pitched by Ted Cruz (R-Texas) called for at least 800 MHz to be auctioned and allowed part of it to be taken from the 6 GHz band that's being used to boost speeds in the new generation of Wi-Fi networks.

Senate GOP budget bill has little-noticed provision that could hurt your Wi-Fi

arstechnica.com Unknown 2025-08-22 02:37:32

Sen. Ted Cruz (R-Texas) has a plan for spectrum auctions that could take frequencies away from Wi-Fi and reallocate them for the exclusive use of wireless carriers. The plan would benefit AT&T, which is based in Cruz's home state, along with Verizon and T-Mobile. Cruz's proposal revives a years-old controversy over whether the entire 6 GHz band should be devoted to Wi-Fi, which can use the large spectrum band for faster speeds than networks that rely solely on the 2.4 and 5 GHz bands.

The Quality of Service feature lets you prioritize activities like gaming or streaming, or set priority devices. Importantly, you can split the 2.4-GHz and 5-GHz bands to show as two separate Wi-Fi networks. This is handy, as some smart home devices only operate on the former band. Similarly, there's a mixed mode for WPA2 and WPA3 security. Some devices don't work with the newer WPA3 standard, and some routers force you to choose one or the other, which can lead to issues.

Trump’s ‘big beautiful bill’ could mean slower Wi-Fi for you

theverge.com Jennifer Pattison Tuohy 2025-08-24 02:28:12

The Senate version of the budget reconciliation bill, backed by President Donald Trump, removes protections for unlicensed spectrum that broadens the capacity of the 6GHz Wi-Fi band. This could result in slower Wi-Fi speeds. Under the bill, which may be voted on at the end of this week, the FCC would sell off some of that spectrum to mobile carriers such as AT&T, which could use it to improve the speed of their mobile data.
