BARCELONA, Spain--Think Verizon Wireless or AT&T's 4G LTE network is fast? Check out Japan.

NTT Docomo's CEO, Kaoru Kato, said he plans to offer download speeds of 112.5Mbps to his company's customers. The higher speeds should come shortly, he said. NTT Docomo is Japan's largest wireless carrier by customer base.

By comparison, Verizon and AT&T boasts speeds of 20Mbps on a good day and an uncluttered network. In practice, the speeds are more in the high single or low double digits.

LTE, Kato said during a keynote address at Mobile World Congress, is key to the company's push to offer its subscribers a bundle of services it calls "smart life." The carrier is looking to wrest control of the customer from the likes of Android or iOS by offering a number of different services, offering everything from its own credit card to medical and healthcare services.

NTT Docomo offers a portal of various digital services that is curated, secure, and filled with high-quality content, Kato said.

Like Verizon, NTT Docomo was early in deploying its 4G LTE network. Kato said the company has 10 million LTE subscribers, and is targeting 41 million subscribers by fiscal 2015.

He said that revenue from these non-core services could grow to $11 billion by fiscal 2015.
