Facebook CEO Mark Zuckerberg. Steve Jennings/Getty On an ordinary workday in mid-2016, a handful of Facebook engineers were sitting on the couches in a corner of the company's Menlo Park, California, headquarters when one of them tossed out a wacky idea.

He suggested doing something that had never been done before and could upend the $350 billion telecommunication market.

"It can't be so difficult to build our own system," the engineer said, referring to the telecom equipment that sends data across cables and wireless networks, a system that could be faster, yet cost less, than the pricey equipment sold by big vendors like Huawei, Ericsson, Cisco, or Juniper Networks.

The engineer was suggesting building the telecom industry's first "white box" transponder, made with off-the-shelf parts such as chips from Broadcom and Acacia Communications, optical equipment from Lumentum, and software from one of the many new networking startups cropping up these days.

Facebook's director of engineering, Hans-Juergen Schmidtke, who was among those on the couch that day, was at first a naysayer.

"I was a little bit skeptical about it at the time," he recounted to Business Insider. As a former engineer at Juniper Networks, Schmidtke knew from experience that building telecom equipment systems was an expensive undertaking that involved hiring teams of specially trained engineers and sizeable research-and-development budgets.

"Building a system 10 years ago was like building a new company," Schmidtke said.

Still, Schmidtke agreed to help this tiny group hack together a white-box system at one of Facebook's hackathons. Three months later the group had a working prototype. Six months later, on November 1, the company announced it to the world as a real product called Voyager.

The product's unveiling sent shockwaves through the telecom industry, putting gear makers on notice that the lucrative market they controlled for decades was about to get turned upside down — and not necessarily to their advantage.

The effort is essentially Facebook, a social-networking company whose bread-and-butter business is online advertising, taking control of its own technical destiny. And the stakes could not be higher for the telecom equipment companies that risk seeing their products become commodities.

Voyager has already been tested by Facebook and the European telecom company Telia over Telia's thousand-kilometer-telecom network. Plus, the German telecom equipment maker ADVA Optical Networking is manufacturing the device and as of a few weeks ago had nine customers trying it out for their telecom needs, a mix of big telecom companies and enterprises, it said. And the Paris-based telecom provider Orange is also testing the device, working with Equinix and the African telecom company MTN.

"We pulled it off essentially showing that when a few engineers can build a system within six months, the world has changed," Schmidtke said.

One person told us that Schmidtke, who is insanely proud of Voyager, has become a star in his own corner of the tech world. When he and his team "go to conferences, they treat him like a tech celebrity, like a rock band," that person said.

From one cult to another

Voyager was the first product, and a major proving point, for Facebook's young Telecom Infrastructure Project, a consortium led by Facebook and launched at the industry's worldwide gathering, Mobile World Congress, on February 21, 2016.

Hans-Juergen Schmidtke. Facebook TIP is a spin-off from a similar organization Facebook launched a few years ago called the Open Compute Project.

Facebook launched OCP and TIP because it sought to take control of the technology used to support its over 1.8 billion people uploading billions of photos, videos, and updates every day.

It has been designing its own IT equipment for years, things like computer servers, hard drives or storage systems, and data-center networks. Its versions were cheaper to build and easier to maintain than standard gear made by companies like Dell, HP, EMC, and Cisco, it says.

Lots of big internet companies build their own tech, including Amazon and Google. But Facebook is unusual in that it openly shares all the designs, literally gives them all away free, inviting anyone at any other company to come work on them, with contract manufacturers standing by to sell it all. It's a concept called open-source hardware.

In this way, Facebook gets lots of help in maintaining and advancing its infrastructure. And the rest of the world gets access to tech designed to work in the most demanding circumstances, like at a huge internet company.

OCP has radically changed the data-center tech industry, and those involved say it has created a cult-like following. For instance, when the secretive Apple refused to join OCP to let its IT engineers collaborate with others, its crew of network engineers quit their jobs. They turned around and launched a startup called SnapRoute and built network software for the OCP community, the story goes. Apple later joined OCP. SnapRoute wound up being the software chosen for Voyager.

OCP created so much competition for hardware vendors like Hewlett Packard and Dell that they opted to join the organization and embrace the white-box concept. The alternative was to be squeezed out of selling their products to companies with the biggest and fastest-growing data centers in the world — not just Facebook but Microsoft, Goldman Sachs, and dozens of others.

There was just one major area that had been somewhat left out of OCP's free and open-source hardware revolution: the telecommunications part. That's the equipment that connects homes, businesses, and data centers across long distances via undersea cables, wireless networks, and so on.

Jay Parikh. Facebook And the big telecom companies, those that spend millions of dollars a year on this gear, wanted in. They were seeking an OCP of their own, Facebook discovered when it launched its Internet.org, CEO Mark Zuckerberg's project to bring internet to underdeveloped countries.

"As we were thinking about Internet.org and helping get more people connected, the idea was, we're doing this thing called OCP to help the data-center community to build infrastructure that's more efficient, more cost-effective, that's greener and more sustainable, more flexible. And we said, can we do that for the telco industry?" Facebook's vice president of engineering, Jay Parikh, said.

"Facebook, having learned from OCP, comes in and says, we can play maybe a catalyzing function," Parikh said, describing early meetings he and his crew had at Mobile World Congress. "We're investing our people and our dollars into technology that is going to solve these problems, and we're going to contribute that technology, that IP," or intellectual property, "into the ecosystem so that you all can benefit from this."

Voyager is one big example. "That's something we developed and it's like, wow, we actually solved a problem that a bunch of operators seem to be struggling with," he said.

Signing on huge partners

Alex Choi, the chief technology officer of South Korea's SK Telecom, agrees that telecom operators like SKT want faster, cheaper, and more open equipment and were inspired by Facebook to take it into their own hands.

Dr. Alex Choi, the CTO, executive vice president, and head of South Korea Telecom's corporate R&D center. Mobile World Live "The idea all started from Facebook," Choi said. "Mark Zuckerberg was always addressing the importance of connecting the unconnected."

In 2015 and 2016, Zuckerberg came to the MWC conference, gave keynote speeches, and hung out with top telecom executives.

He wanted to know what was keeping those people off the internet. He discovered that bringing telecom services to far-out parts of the world "was too expensive" for telecom operators, Choi recalls.

Facebook wanted to help bring the costs down. But developed nations in Europe, Asia, and the Americas had the same problem. People are buying more devices, using more video. And with the Internet of Things, millions more objects are joining the internet daily, communicating over telecom networks.

"There's a huge growing traffic demand," Choi said. "That means we have to install more base stations, find more sites, invest more in the fiber and the backbone and supporting IT infrastructure." But telecom companies can't charge more to cover the costs. People are pushing them to charge less, for unlimited data plans.

When Facebook executives (including Aaron Bernstein, responsible for partnerships with mobile providers, and Jason Taylor, Facebook's vice president of infrastructure who leads OCP) approached him about forming the new organization, Choi liked the idea so much that he became the chairman of the TIP organization.

It felt revolutionary.

OCP has invented lots of cool new hardware for the data center, and telecom operators had never banded together to build their own gear, he said.

"Operators rely too much on the big telco incumbent vendors," he said. "We kept pushing the vendors to do more innovations, to do something to bring down their premium price tag. They are making efforts and making progress but not as fast as we want them to be. So what can you do? You explore other opportunities."

Deutsche Telekom's Axel Clauberg was in a similar boat. He first got in touch with Facebook in 2015 about participating with OCP's networking efforts.

There had been a push for more telcos to join OCP at that time because Facebook has been helping usher in a new way to build computer networks. It takes all the fancy, complex features out of the hardware and put them into software. In the corporate network world this push is called software-defined networking. But it's happening in the world of telecom service providers, too, where it's called Network Function Virtualization, or NFV.

Facebook didn't invent SDN or NFV, but in the slow and conservative world of network engineering, OCP and TIP are radically pushing these concepts forward. OCP is proving the technology works even for a huge demanding internet site like Facebook or for a giant telecom network like AT&T.

"We are facing exponential traffic growth," Clauberg said. "We needed to do something."

And there's one more issue going on besides tight budgets and huge growth, he said: the war for talent. Decades ago, hardware and communications engineers went to the telecom companies to build amazing new things, like mobile networks. Then they went to the tech companies like Cisco to build the tech that created the internet. Today, they are going directly to the internet companies like Google and Facebook and creating new hardware so they don't have to rely on the vendors, he said.

TIP gives them a way to access the smartest minds without having to poach them.

When engineers graduate from college, Clauberg said, "which companies are they looking at?"

"In old days," he said, "it was the telcos. Then it was the suppliers, now it's the internet companies. The funny thing is with OCP, you have all these parties working together. I envision achieving the same [with TIP]. So having players from internet companies, from startups and established vendors, and the telcos, working together on what the infrastructure of the future should look like."

Clauberg joined TIP as a founding board member, alongside SKT's Choi. This was a powerful first step. SDK and DT are two of the most advanced telcos in the world, role models for many others. Facebook also persuaded Intel's Caroline Chan to join TIP, which was an easy sell. Intel is also a founding member of OCP. And TIP was off and running.

But there was one surprise founding member of TIP: Nokia's Laurent Le Gourrierec.

The brave choice of Nokia

Telecom devices that can be put together with standard parts and software are deeply threatening to the multibillion-dollar telecom equipment market dominated by companies like Huawei Technologies, Ericsson, Cisco, ZTE, and Nokia.

Axel Clauberg, VP in the Technology Innovation/Group, Deutsche Telekom YouTube/GEN15 And Voyager isn't the only product. TIP's OpenCellular project is working on an open-source 4G LTE/LTE base station, the hardware and the software.

As SKT's Choi describes it, TIP wants to "democratize" the technology, making it easier for anyone to build, use, or modify. That means taking it out of the hands of the equipment providers who create proprietary radios and base stations today.

TIP's impact won't happen overnight, explains analyst Rohit Mehra, the vice president of IDC's Network Infrastructure practice. But the goal is clear: to overhaul the telecom equipment industry, which he says is about a $350 billion market when factoring in software, hardware, and services.

"This is not the first time Facebook has done this," Mehra says. "They've been somewhat successful with what they call OCP. The Telecom Infrastructure Project is disruptive not just to telecom-equipment makers but in some cases the telecom service providers. Though in some cases it helps the service providers because it intends to give them more cost-effective infrastructure."

So TIP is, in some ways, threatening Nokia's main telecom business.

But Nokia is a close partner of Facebook and the one telecom equipment vendor embracing TIP as a founding member and board member.

Le Gourrierec of Nokia explains why using an adaptation of an Abraham Lincoln quote.

"The best way to predict the future is to invent it," he tells Business Insider. "You have all these equipment makers saying, 'The world is changing so let's try to hold on to what we know.' But the thing is that the world is changing anyway, so it's much better to take an active role in shaping the future."

If all goes well, TIP and Facebook will actually help create new customers using new telecom services, those people in undeveloped nations who never had telecom or internet, Le Gourrierec believes.

"So it's best to participate in the definition of new partnerships, new services in partnership with the existing actors in addition to the new ones," Le Gourrierec said.

From spies to community members

When Facebook created Voyager, Nokia didn't shake in fear. Engineers there thought, "Maybe we can learn something for this," Le Gourrierec said.

But there are other equipment makers that are, technically, part of TIP too. Currently the organization boasts more than 100 members from all facets of the industry.

But Choi, Clauberg, and Le Gourrierec said many of them had only been nervously watching the group so far.

Laurent Le Gourrierec, the vice president of strategic partnerships at Nokia. Nokia "They are not actively contributing," Le Gourrierec said.

Obviously, the kumbaya concept of open source doesn't work well like that. Everyone has to contribute ideas for a community to blossom.

One way TIP is encouraging them to jump in is a different approach to sharing intellectual property. Participants don't have to give away all their closely held, lucrative ideas and secrets the way they do with OCP or with other open-source organizations like Linux.

Each working group in TIP can instead decide to use an older, more established method for sharing, known as Reasonable And Non-Discriminatory Terms. RAND allows vendors to be paid tiny fees by everyone who uses their intellectual property as long as those fees are reasonable and the tech is made available to everyone without bias. The company can't, for instance, jack up the price to its competitors.

The TIP board members are also encouraging participation by telling members that TIP will lead to plenty of other new commercial opportunities, too, even if TIP successfully turns the hardware into low-cost generic white boxes. Teleco providers can instead develop new software that can be bought via lucrative subscriptions, similar to the software startups that have sprouted up around OCP.

In fact, Nokia is already experimenting with a high-performance software product able to run on low-cost, ordinary computer network hardware. It's geared toward businesses, not service providers, but it's a start, Le Gourrierec tells us.

TIP is also encouraging engineers and companies to join by creating a "culture" working group that helps teach telecom engineers how to "work fast and break things" as the internet world does.

"One of things we learned in the last 1.5 years in working on TIP is people saying, 'How do you help me transform my culture and my team so that we can move faster?'" Facebook's Parikh said.

Telecom is a world that traditionally frowned on that. Working fast and breaking things could take down the network and get you fired.

The culture group has become a popular entry point for engineers wanting to check out TIP. They then bring these ideas back to their jobs. It helps some engineers become more open-minded about sharing. For others, like Le Gourrierec, it inspires "a new sense of urgency," in his work at Nokia, he describes.

Afraid of Facebook

We heard only one major criticism regularly lobbed at TIP: that Facebook is becoming extremely powerful. Maybe too powerful. After Facebook launched Voyager, Facebook dominated the gossip at the latest Mobile World Congress, sources told us.

A Facebook Voyager optical network device. Facebook Facebook is making equipment with TIP and OCP, it has state-of-the-art data centers, it has a roster of talented engineers, and it is also laying its own telecom cable, including a new record-breaking fast subsea cable installed with Nokia between New York and Ireland.

It could snap its fingers and become a powerful telecom and cloud operator tomorrow, some people fear (and others predict) as Amazon did with Amazon Web Services or Google did with Google Cloud and Google Fiber.

But Parikh said Facebook had zero interest in doing that. "We aren't operating any networks ourselves. We are trying to help the telcos solve this," he said. The idea is to "share" lessons and technology to "always benefits" the whole community.

SKT's Choi just shrugs off the idea that Facebook is a threat, saying telecom operators have more to gain than to lose.

"I can understand the concern. It's very much natural, because operators are always being disrupted," he said, especially by large American internet companies "like Amazon, Google, and Facebook."

Facebook's OpenCellular access point. Facebook TIP "But in the long run, I strongly believe in mutual benefits," he said. He notes that because Amazon helped create cloud computing, there are new billion-dollar markets and "everyone benefits." He added: "I think the same thing will happen in the teleco sectors."

Not everyone is convinced that TIP will succeed. IDC's Mehra cautions that it's a huge undertaking and the two biggest telecom equipment vendors, Ericsson and Huawei, have remained cool toward the project, for obvious reasons, he says.

"TIP may see progress over the years. But the challenges are higher. They are working on four to five different domains of telecom infrastructure, each with its own set of technologies and own set of tech providers," Mehra says.

All the board members of TIP acknowledge that the project is in its early days and could fail. It could fail to attract a community. It could fail to produce products the world wants to use.

But they believe it will succeed.

"Today most telcos remain as the status quo, but all the telcos leadership, if you ask them, they want transformation," he said. "They want changes. They want innovation. They have to overcome it by collaborating with Facebook and others. Again, witness all the innovations that have already happened in the cloud industry. We want to apply all those innovations to the telco industry, which will make operators happier and customer happier and for everyone, a win/win."
