4G Mobile technology

1. The mobile communications comprise two steps: access to the mobile network, and access to the mobile services. Traditionally, these two steps are all controlled by one operator in a closed and proprietary way. In the 4G mobile era, the access to the mobile services will be evolved to an open Mobile Cloud so that it is fully open to any developers and providers.
2. The mobile device system architecture will be open in order to converge multiple RTTs (radio transmission technologies) in one same device. Same as laptop computer, the future Smartphone will be based on open wireless architecture (OWA) technology which means, when you change the wireless standards, you do not need to change phone
3. Any portable consumer electronics device can be a mobile phone by inserting the OWA-powered mobile RTT(s) card. This approach is truly converging the mobile wireless technology with the computer technology.
4. More breakthrough technologies are being developed for efficient utilization of wireless spectrum, and the dynamic and open spectrum management.
5. Power efficiency is another critical issue for mobile device. The system architecture must be open to enable removable of unused modules, and the processing architecture must be optimized to the lowest possible in terms of the whole system performance. Meanwhile, the RF radio modules should be narrowed to the minimal meeting the basic requirements of necessary RTTs.
