Comcast suffers big outage after fiber cuts

On Friday, 30-June-2018 Comcast suffered a major outage impacting users across the United States. The disruption appeared to last 4-5 hours. There was no word on how many of Comcast's 26 million broadband customers were affected.

In a statement, Comcast said: "We identified 2 unrelated fiber cuts to our network backbone providers. Our engineers are restoring services to business & residential internet, tv & voice customers. Apologies to those affected."

Keysight supplies 5G protocol tester to MediaTek

Keysight Technologies is extending its collaboration with MediaTek to accelerate 5G New Radio (NR) chipset development and testing of 5G NR protocol stacks.

Specifically, MediaTek will use Keysight’s 5G Protocol R&D Toolset for Layer 2 and Layer 3 protocol development, pre-silicon deployment, and full stack chipset validation across sub-6GHz and mmWave frequencies using the latest 3GPP Release 15 5G NR standards.

“Keysight is excited to offer our industry leading 5G expertise and elevate our long-term collaboration with MediaTek in 5G wireless technologies to speed up deployment of 5G NR technologies and products to the market,” says Kailash Narayanan, vice president and general manager of Wireless Devices and Operators at Keysight Technologies.

Keysight announces 5G NR Emulation

Keysight Technologies announced its PROPSIM F64 5G Channel Emulation Solution – the industry’s first 5G New Radio (NR)-ready channel emulation solution. Keysight’s PROPSIM F64 5G Channel Emulation Solution enables chipset, device, and network equipment manufacturers to characterize end-to-end system performance of the latest 4G and 5G base stations and mobile devices by emulating real-world radio conditions in the lab.

Keysight said its PROPSIM F64 5G Channel Emulation Solution supports all 5G NR signal bandwidths, carrier aggregation (CA) schemes, and offers the highest number of channels for massive MIMO channel emulation and testing. The solution integrates channel modeling tools for user-defined 3D spatial scenarios and dynamic modeling of movement. It supports both conducted and Over-The-Air (OTA) testing across sub 6 GHz and mmWave frequencies.

“With the PROPSIM F64 5G launch, Keysight is the first to deliver a portfolio of 5G NR-ready channel emulation solutions across all 5G new radio signal bandwidths and carrier aggregation schemes,” said Kailash Narayanan, vice president and general manager for Wireless Device and Operators at Keysight. “The new 5G Channel Emulation solution delivers end-to-end realistic and repeatable real-world performance testing in the lab, and enables real world emulation of networks essential for 5G deployment.”

  • In December 2017, Keysight was also first to introduce a 5G NR-ready network emulation solution which allows the entire mobile ecosystem to benefit from a common scripting engine that uses interactive 5G stack and tools, breaking down the silos and disconnected workflows between teams, and achieving cost-efficient testing.
