Mobile systems first emerged in Japan in 1950 in the form of the police wireless network. Since then the technology has improved as, one after another, the railways, the airlines, shipping companies, the fire service, local government and the like, have taken it up. Today, the technology is expanding rapidly in the highly prospective mobile phone and mobile computing fields. In an environment where mobile communication systems are heading into a new phase with acceleration of data transmission speeds and the launch of next generation systems, as a pioneer of mobile systems and the builder of the mobile networks for the majority of major domestic mobile network operators, Net+it works offers a wide range of mobile and network solutions.
