Opportunity knocks for open RAN hopefuls in the UK. They have been invited by the government to enter a competition offering cash prizes from a pot of £30 million ($41.3 million) for the best-performing contestants. Think of it as a Britain's Got Talent for open RAN, probably untelevized and without Simon Cowell as a judge.
It is the UK's latest attempt to help cultivate 5G alternatives to big kit vendors Ericsson and Nokia, which are set to be the country's dominant 5G infrastructure providers once operators have expunged all traces of China's Huawei – something the government has ordered them to do by 2028.
The much-anticipated 5G Standalone has arrived. T-Mobile is the first to launch it in the USA, covering 250 million people across 7,500 cities and towns, including rural areas. China Mobile is the only other service provider to launch it in Hong Kong. Overall, 58 operators are currently investing (November 2020) in 5G SA, including those who have launched.
5G SA makes a break from 5G non-standalone by integrating the evolved packet core or the signaling brain of the 5G network, which controls the network's devices. It prepares the groundwork for new services unique to this generation of networks, such as network slicing to customize enterprise services across multiple networks.
Although the cause is as yet unknown, this breach is likely to have the same culprit as most large scale data breaches that have occurred in recent memory, through a simple misconfiguration of a server or shared repository. As the sheer size, scale, and footprint of global technology vendors like Microsoft, Facebook, Google, and so on continues to grow, so too does the opportunity for simple errors to make their way into some infrastructure configurations that can then be exploited.
Cisco envisions a future in which enterprise’s WANs are connected not by MPLS or broadband, but instead by high-speed, low-latency cellular networks, or what it calls the wireless WAN. Once relegated to failover, Cisco says today’s cellular networks, in particular 5G, offer high enough throughput and low enough latency to be viable alternatives to traditional wired networks. “About 10-years back everyone would say that my primary circuit from the enterprise branch was MPLS and then the higher bandwidth speed of having an internet circuit became a viable alternative,” said Shankar Ramachandran, director of product management, routing platform at Cisco, in an interview with SDxCentral.
