NIST finds wireless performance consistent across 5G millimeter-wave bands

Wireless transmissions can take many routes to the intended receiver. The colored lines are reconstructions of measured paths of millimeter-wave signals between a transmitter (not visible) and receiver (lower middle) in a NIST industrial control room. Each path is precisely characterized in terms of length and angle to the receiver. These paths are all secondary,…

Tech vs telecoms: EU ignites debate on ‘net neutrality’

Web giants including Google and Netflix accounted for more than 55 percent of online traffic globally last year, a study claimed. Tech and streaming giants suck up vast amounts of bandwidth, so the EU this week revived a long-standing idea to make them pay the telecom firms who maintain the infrastructure. But the idea, which…

Wi-Fi may be coming soon to a lamppost near you

NIST communications researchers traveled to downtown Boulder, Colorado, to verify their channel model for evaluating high-frequency wireless network designs. Sung Yun Jun is checking the alignment of the transmitter, mounted 6 meters high on a mast, with the receiver antenna array on the roof of the blue van. Derek Caudill, barely visible inside the van,…

Existing infrastructure will be unable to support future demand for high-speed internet

Credit: Pixabay/CC0 Public Domain Researchers have shown that the UK’s existing copper network cables can support faster internet speeds, but only to a limit. They say additional investment is urgently needed if the government is serious about its commitment to making high-speed internet available to all. The researchers, from the University of Cambridge and BT,…

Trial of high-speed broadband delivered through water pipes

Credit: Unsplash/CC0 Public Domain Fast broadband will run through water pipes in parts of South Yorkshire as part of plans to get better internet access to people quicker. New proposals to accelerate the rollout of broadband without digging up roads would see fiber-optic cables deployed through 17 kilometers of live drinking water mains between Barnsley…
