Singapore Transport Authority enhances critical railway infrastructure with optical LAN | Computer Weekly


For modern transport systems, operating a real-time surveillance system that is highly available, reliable and secure is vital to ensuring the safety of those travelling. To achieve these objectives in Singapore, the local transit authority has deployed Nokia IP/MPLS and fibre optical local area network (LAN) solutions.

The Singapore Land Transport Authority (LTA) spearheads land transport developments in the city state, with the stated responsibility to plan, design, build and maintain land transport infrastructure and systems. Since the inception of LTA in 1995, the land transport network has transformed significantly, with more than 160km of expressways spanning the island, an MRT network of more than 200 km, over 600 km of cycling paths and park connectors and increasingly varied commuting options.

The LTA said it aspires to strengthen Singapore’s land transport connectivity and integrate a greener and more inclusive public transport system complemented by walk and cycle options, using technology to strengthen its rail and bus infrastructure and develop “exciting” options for future land transport.

The technology installation is part of video surveillance upgrade to its critical railway infrastructure for which CCTV cameras are regarded as playing a crucial role within the LTA railway system. With CCTV cameras placed across more than 50 stations, the LTA needed a network infrastructure that could meet its growing capacity demands providing real-time monitoring and video surveillance services that ensure public safety, help spot illegal activities and manage traffic patterns.

Working in partnership with Hitachi Rail, Nokia was confident that its solutions will enable the LTA to significantly enhance its CCTV network used across Singapore’s heavily used railway system serving millions of passengers per day.

To support its expanding network cameras and growing bandwidth requirements, the LTA deployed Nokia’s fibre optical LAN including hardened optical network units (ONUs) and optical light terminals (OLTs) capable of supporting data transmission speeds of 25Gbps. The optical LAN requires up to 70% less cabling and 40% less power compared with traditional copper-based LAN networks. Nokia claims that its IP/MPLS deployment also enables LTA to more effectively backhaul the network data traveling to its operations control centre where live video streams are viewed and stored. 

Commenting on the deployment, Stuart Hendry, vice-president of enterprise sales and network infrastructure for Asia Pacific at Nokia, said: “Fibre is being used to connect everything, including video systems that are critical to monitoring transportation hubs around the world. Partnering with Hitachi Rail, we were able to deliver a complete solution for LTA that would ensure they had the video capacity needed to serve their expansive CCTV surveillance and broader network operations for years to come.”

Joaquim Santos, vice-president of integrated communication and supervision solutions (ICS) at Hitachi Rail, added: “We are pleased to have selected Nokia to collaborate with Hitachi Rail in enhancing passenger safety and security across Singapore’s railway network, which is a continuation of Hitachi’s long-term relationship with LTA. This project will play a key role in upgrading the transport infrastructure.”

As it was making the Singapore LTA optical LAN deployment, Nokia announced the launch of its 1830 Photonic Service Switch-High Capacity (PSS-HC) shelves, a next-generation addition to the 1830 PSS optical transport platform family. The new shelves are designed to deliver up to three times higher density with up to 60% lower power consumption per bit, enabling service providers to more cost-effectively scale their networks.

FCC Enforcement Chief Offered to Help Brendan Carr Target Disney, Records Show

Published

on


A senior Federal Communications Commission official overseeing ABC-owned California stations privately offered to assist FCC Chairman Brendan Carr’s campaign last year against the Walt Disney Co. and Jimmy Kimmel Live!, according to internal emails obtained by WIRED.

On September 17, Carr threatened Disney with regulatory action regarding the Jimmy Kimmel monologue about the assassination of Charlie Kirk, prompting major station affiliates to drop the broadcast and forcing ABC to temporarily suspend the show.

Later that day, Lark Hadley, the FCC West Coast enforcement director, emailed Carr and FCC chief of staff Scott Delacourt. The email, obtained via the Freedom of Information Act, was titled “personal note of support re Charlie Kirk ABC/Disney issue” and quoted Carr’s remarks from an interview with conservative podcaster Benny Johnson: “This is a very, very serious issue right now for Disney. We can do this the easy way or the hard way,” Carr said during the interview.

Noting that he had been a broadcaster himself, Hadley wrote that the “absolute lack of accountability has always confused (and sickened) me,” telling Carr and Delacourt: “Please, do not let up, and let me know if I can help in any way.”

It is highly irregular for a career civil servant and enforcement chief to express support for a politically motivated pressure campaign, or pledge services to a targeted retaliation effort against a broadcaster in their own jurisdiction.

Federal ethics rules prohibit government employees from participating in matters where their impartiality could reasonably be questioned.

Carr’s office did not respond to a request for comment.

While FCC headquarters typically handles television content complaints, Hadley’s office holds direct enforcement authority over physical ABC-owned stations in its jurisdiction, including KABC-TV in Glendale, the broadcast origin for Jimmy Kimmel Live!

The brief suspension of Jimmy Kimmel Live! became a defining test of Carr’s ability to leverage the FCC’s regulatory apparatus against political critics. Following Carr’s public threats, major affiliate networks Nexstar and Sinclair—both of which had multibillion-dollar mergers pending before the commission—refused to air the program, forcing Disney to temporarily pull the show.

An ABC spokesperson did not immediately respond to a request for comment.

Will Creeley, legal director at the Foundation for Individual Rights and Expression, tells WIRED that regional directors like Hadley have no business cheering on the FCC chairman’s regulatory threats against broadcasters that air views the president doesn’t like.

“Just like Brendan Carr, they swore an oath to uphold the Constitution—and that includes the First Amendment, which bars the government from coercing private broadcasters into censoring dissent,” Creeley says. “This is a public servant paid by our taxpayer dollars. Is it too much to ask for him not to sound so excited about the chairman abusing the power of his office?”

A New Game Turns the H-1B Visa System Into a Surreal Simulation

A New Game Turns the H-1B Visa System Into a Surreal Simulation


More than half of the nine developers who worked on the game have either obtained a US visa or tried and failed to do so. Most of them are from China, but the team also intentionally recruited talent from other countries in the hopes of incorporating more diverse immigrant perspectives.

“Everybody knows somebody that’s on a visa, but not all of them are vocal about that part of their identity,” says Andrea Saravia Pérez, an immigrant from Colombia who joined the team in February as a narrative designer. “How can we develop a project that’s interactive and shows people this immigration system that a lot of Americans are not familiar with?”

There’s growing interest across the gaming industry in making political games, says Yang. When her team brought H1B.Life to the annual Game Developers Conference in San Francisco last week, she says they received a tremendous amount of interest and support because they are tackling an important societal issue without expecting to make much profit. (The game was supported by a philanthropic organization and the developers also plan to raise additional funding from a future Kickstarter campaign.)

Yang says she has also heard from people in Germany and Australia interested in licensing or adapting the game for different countries. “The whole world is turning right, and life is getting more difficult for all immigrants,” she says.

“If we can just put people in our shoes, I think it can create a very positive impact,” says Saravia Pérez. “As long as players come to have fun and are able to sympathize and understand it a little bit more, I think that we’ve done our job as a team.”

Technicalities Versus Emotions

The H-1B visa program, created in 1990, is one of the most reliable US immigration pathways for white collar workers with college degrees. In recent years, the program issued about 85,000 visas annually, but since there are often more applicants than slots, a lottery system determines who ultimately is chosen. And if you don’t get it, you have to wait an entire year before you try again. Every person who has gone through the process has their own success or failure story to tell, me included.

The team behind H1B.Life started developing the game by interviewing immigrants. So far, Yang says they have talked to over two dozen people about their H-1B journeys and used those interviews to make the game more realistic and accurate. The biggest challenge now is to figure out how to balance explaining complicated immigration rules accurately and ensuring the game is still entertaining.

Signal’s Creator Is Helping Encrypt Meta AI


Moxie Marlinspike, the privacy advocate who created the secure communication app Signal and its widely used open source encryption protocol, said this week that his privacy-focused AI platform, Confer, will start incorporating its technology into Meta’s AI systems.

Every day, billions of chat messages sent through Signal, Meta’s WhatsApp, and Apple’s Messages are protected by end-to-end encryption. The feature, which makes it impossible for tech companies and anyone other than the sender and recipient to snoop on your messages, has become mainstream over the past decade. As generative AI platforms explode in popularity, though, people are now also exchanging billions of messages a day with AI chatbots that don’t offer the protection of end-to-end encryption—making it easy for AI firms to access what you talk about.

This is by design, given that platforms often want to train their AI models on as much user data as possible and have made it hard to opt out of having your information used as training data. But as chatbots and AI agents have become more capable, some technologists and companies are pushing to create more constrained and privacy-focused systems.

“As LLMs continue to be able to do more, we should expect even more data to flow into them,” Marlinspike wrote in a short blog post about his collaboration with Meta published on Tuesday. “Right now, none of that data is private. It is shared with AI companies, their employees, hackers, subpoenas, and governments. As is always the case with unencrypted data, it will inevitably end up in the wrong hands.”

Marlinspike wrote that he will “work to integrate Confer’s privacy technology so that it underpins Meta AI.” He also emphasized that Confer, which debuted at the beginning of this year, will continue to operate independent of Meta. The project’s goal, Marlinspike added, is to offer a technology that “allows everyone to get the full power of AI along with the full privacy of an encrypted conversation.”

In 2016, Marlinspike worked with WhatsApp, which is owned by Meta, to roll out end-to-end encryption to more than a billion accounts simultaneously. Over the last year, WhatsApp has introduced a Meta AI chatbot into its app, which isn’t shielded from the company in the same way individual chats are.

“People use AI in ways that are deeply personal and require access to confidential information,” WhatsApp head Will Cathcart wrote on Wednesday on the social media platform X about the collaboration with Confer. “It’s important that we build that technology in a way that gives people the power to do that privately.”

The adoption of encrypted AI is still emerging. The cryptographic schemes used in end-to-end encryption for traditional digital communication aren’t easily or directly translatable into data protections for generative AI. For its part, Confer is still a new project, and Marlinspike’s blog post did not provide specific details about how exactly the collaboration with Meta will work or what the specific goals are for integration.

Neither Marlinspike nor Meta provided WIRED with additional comment ahead of publication.

Mallory Knodel, a cryptography researcher at New York University, says it would be “great for people using chatbots that use Meta AI to have confidentiality and privacy within that exchange.” Crucially, that means Meta would not be able to access AI chat data for training, says Knodel, who along with colleagues recently published a study on end-to-end encryption and AI. “I really hope more AI chatbots adopt this approach.”

Knodel’s preliminary, initial assessments of Confer indicate that the platform isn’t perfect, but is an important example of how to build a private AI chatbot.
