However, given

The nation’s fastest community-wide internet? New 25-gig service launches at $1,500 per month

Credit: CC0 Public Domain It’s a bird. It’s a plane. It’s the nation’s fastest community-wide internet service, and it’s making its way to a Tennessee city and convention center. EPB, an internet, TV, phone and energy company in Chattanooga, has launched a community-wide, 25-gigabits-per-second internet service. The service will be available to all residential and

Efficient satellite downlink with a Ka band dual circular polarization transmitter

Credit: Tokyo Tech Low earth orbit (LEO) satellites are being increasingly used for environmental monitoring of the earth, as well as for logistic purposes, such as the navigation of maritime vessels. The data transmitted from the satellite terminals to the receivers on Earth, known as “downlink,” is steadily increasing and, as a result, requires new

AT&T rolls out cutting-edge 911 call tracking technology

That’s why the first question a 911 dispatcher asks is, “What is the address of the emergency?” A decade ago, if someone called and didn’t know the address, emergency call centers would send out police officers with their sirens on and tell the caller, “Tell

Verizon, AT&T delay some 5G service over airlines’ concerns

A JetBlue passenger flight lands at Reagan Washington National Airport in Arlington, Va., across the Potomac River from Washington, Wed., Jan. 19, 2022. On Friday, June 17, 2022, federal regulators said Verizon and AT&T will delay part of their 5G rollout near airports to give airlines more time to ensure that equipment on their planes…

Introducing a transceiver that can tap into the higher frequency bands of 5G networks

Credit: Tokyo Tech 5G networks are becoming more prevalent worldwide. Many consumer devices that support 5G are already benefiting from increased speeds and lower latency. However, some frequency bands allocated for 5G are not effectively utilized owing to technological limitations. These frequency bands include the New Radio (NR) 39 GHz band, but actually span from…

Space-enabled system to digitalize airspace goes global
