Building Japan’s fourth cellphone carrier from the ground up.

Of all the entities today, I think the founder and chairman of the company, Mickey [Hiroshi “Mickey” Mikitani], is probably one of the most innovative leaders I have ever had the opportunity to work with. I cannot tell you how much I enjoy the interactions we have with him. He is down to earth and his leadership style is definitely hands-on; he doesn’t really operate at a high level.

When you say Symphony, do you mean the wireless network technology or the technology of the whole company? The launch of Reliance Jio was very successful and became a really good Cinderella story for the industry. I am extremely thankful for what Jio has taught me personally, and I have always wondered what I would do differently if I had a second opportunity to build a greenfield.

Let me be really honest with you, this was just in PPT at the time. I conceived the idea thinking about what I would do differently if I were granted another opportunity like Reliance Jio. One of the first key elements I wanted to change is adopting this unique cloud architecture, because nobody had really deployed an end-to-end horizontal cloud across any telco yet.

That is the high-level story of how this journey started with a super crazy, ambitious idea that nobody thought would succeed. If you go back four years to some of the press releases that were published, I cannot tell you how many times I was told I’m crazy or that I’m going to fail. As I said, we became fanatic about this idea, and that is what drove us all to emotionally connect to the mission, the objective. I am very, very happy to see the results that the team has achieved.

This is how I have operated all my life, and so far, I am really happy with some of the thinking I have adopted. I am not saying people should not have options in their lives, but this idea of “no Plan B” has its merits in certain projects. How can you adapt your leadership style when approaching projects, rather than thinking, “What is the other option?”

At the time, LTE was the service that Jio launched with. I was really amazed by this ambition and how big it was. I said, “This is an opportunity I just cannot pass up.” It was much bigger than the financial reward; it was an opportunity of learning and understanding. I truly enjoy meeting different cultures. The more I interact with people from different parts of the world, the more it fuels the energy inside me.

In terms of building a network at a relatively low cost, I will explain how this Open RAN idea came in. During my tenure at Jio, I really started thinking that in order to build a network at scale, regardless of how cheap your labor is, you need to fundamentally change your operating platforms for digitization. Jio would have north of 100,000 people a day working in the field, deploying sites.

I prepared an amazing presentation about small cells to the leadership team of Jio and I thought I kicked it out of the park. But then I was asked a question I have never heard in my life. Imagine! I am a veteran in this industry and have been doing this for a very long time. Someone said, “Tareq, I love your strategy.

Let me ask you more about that. Jio is a transformative network, and is now obviously the most popular in India. You were able to offer a much lower-cost product than the traditional cell providers with what sounds like very clever business moves. You went and negotiated new kinds of supplier agreements and you said, “We have to actually integrate our products, find lower chips at cost, and make our own products. We have to build a new, efficient way to deploy the network with our technicians.

If we build these operation platforms on a new modern architecture that supports real-time telemetry, the idea is to get real-time information about every element and node that you have into your network. Being able to correlate them and apply AI machine learning on top of them requires modern-age platforms. It is so critical to my dream.

This concept has been talked about, but nobody was willing to take the risk in any startup. Maybe I was wrong that your job is secure if you pick a traditional vendor. That is what I was thinking through, four years ago.Let me ask you this. Is it because the initial investment is so high? There are not many startup wireless networks in the world. When they do start, they need an enormous amount of capital just to buy the spectrum.

The foundation of success for Rakuten Mobile today started by Rakuten itself enabling and acquiring one of the most disruptive companies in this Open RAN space. We, and I thought they had everything one could dream about, except nobody was willing to give them a chance. I diversified my hardware supply chain and purchased hardware through 11 suppliers. I mandated where manufacturing can happen, in terms of product, security, and chipsets.

You have described Rakuten’s network as being in the cloud several times. Very simply, what does it mean for a wireless network to be cloud-based? When it comes to the cost, this is a hyper-operation structure. There are 279,000 radiating elements, and the operational headcount in Rakuten Mobile is still sitting below 250 people.As the number increases, there is no direct proportionality between the number of units in the network versus the number of employees in the network. There is absolutely no direct correlation whatsoever anymore. To me, that is what cloud is all about.

The way I think about it, it is not subsidized by the ecosystem. If I acquire you as a mobile customer, because of the impact I could bring to that larger sales contribution of you potentially buying from e-commerce or travel, I am using connectivity to empower the purchases of these 70-plus internet services, so we are actually contributing to the larger group. As long as the total top line revenue is increased because of mobile contribution, the group as a whole is going to be in good shape.

Think of cloud gaming. It has never been successful, at least in wireless, because networks could not sustain the latency that it would require. Speed, in my opinion, is a stupid metric to talk about. We should talk about latency, latency, latency! How do you deliver sub-4-millisecond latency on a wireless network?

I have brought in 17 nationalities — relocated, not as expats, as full-time employees in our office in Japan. Being this diversified, multicultural organization was the key. I did my own recruiting and handpicked my team. My focus was initially to find people with the spirits of warriors, that were willing to take on tough challenges and the bruises that came along with them, that would not get discouraged by people telling them something would not work.

The more I look at the world, the more I see the success of companies that have invested heavily into the right skill sets, whether it is from data science, AI, ML, or the various software organizations that they have built. This is what I thought we needed. To be very honest with you, I love the idea of having more competitors in this space. It challenges my own team to stay on top of their toes, which is really good. At the same time, having more entrants come into the space would help me cultivate the hardware ecosystem today.

Since it’s public in the US, I can talk about it. As I mentioned before, it is not just about the O-RAN discussion for me, it is about the whole story. We announced in the last Mobile World Congress that AT&T is working with Rakuten Symphony on a few disruptive applications around the digital workflow on the operation for wireless and wireline, the same as Telefónica in the UK and Telefónica in Germany. Our first big breakthrough was an integrated stack.

Yes. Before we were approved as a mobile company to be able to sell their devices, I have to tell you about the pleasure of working with the likes of Apple. I’m being really honest about this; I really liked it. Their burden to quality was really high, as was their ability to accept and certify a quality of network. I thought if we got the certification that we needed from them, that’s another third-party audit; I would have cleared a big quality hurdle.

The device vendors were very supportive. The skepticism came from the fear, uncertainty, and doubt from traditional OEMs and vendors who wanted to tell everybody that this technology is horrible. It was to such an extent I ignored everything. I still do today. I say you cannot argue the benefit of cloud brought to IT and enterprise. There is an indisputable benefit to this.

I think a couple of things in India really benefit the country quite a bit. When you have massive volume, people are intrigued to enter these economies that exist. Certain things have changed in Japan as well. The government policies are mandating the support for open device ecosystems., which gives you the ability and flexibility to switch carriers within one second. You can just say, “Oh, I don’t like this. I like this.” The freedom of choices is just unparalleled.

What is the biggest challenge of O-RAN? You have a long history in this industry. I’m sure many challenges are familiar to you in building a traditional network. What is the biggest, most surprising challenge of building it in this way? “My number-one challenge with Rakuten Mobile is to find hardware suppliers, because there are not a whole lot of them for Open RAN.”

Let’s differentiate between large companies and new entrants. I think new entrants in hardware are comfortable and content, understanding the value they provide by being commodity suppliers. Let me give you an analogy. Let’s say Apple uses Foxconn to manufacture its devices. I am sure Foxconn will not tell you they are unhappy about this business model.

, a digital workflow tool. Look at the difference between them. One is a complete SaaS model; one lives on a traditional business model. I don’t think the market appreciates and recognizes that this may be the right thing to do. First, we had to prove to the world that a new technology actually works and delivers on cost, resiliency, and reliability. That’s a check mark; done. That is not just me telling you today, but audited by a third party. Look at the performance, quality and reliability we do. Second, if you are in the mobile business, I think you have one area that new technology cannot easily solve for you. You need to have ubiquitous coverage everywhere and anywhere you go.
