ITRI Showcased Smart City Solutions at MWC 2017
The Mobile World Congress (MWC), the world’s largest gathering for the mobile industry, was held in Barcelona between February 27 and March 2. For this grand event, ITRI showcased its smart city solutions in the Taiwan Pavilion, including the wireless communication service on bus and the Ultra-Dense Network (UDN) technology.
Y5Bus, developed by ITRI, provides a distinctive, integrated total IoV (Internet of Vehicles) solution for bus fleet management and passenger services. The App combines advanced driving support and real-time video streaming, providing the control center with multiple vehicle dynamics that enhance fleet safety and efficiency. The App can be customized and integrated with a user’s social media account, enabling passengers to browse a bus company’s Over-the-Top (OTT) line-up of services to make the journey more enjoyable. Simultaneously, bus companies can learn more about their passengers as the platform can analyze device profiles and customer behavior. Combining with ITRI DSRC V2X solution and safety application, a better experience of connected vehicles is being created.
Dr. Tzi-Cker Chiueh, General Director of ITRI’s Information and Communications Research Laboratories, explained that ITRI’s Y5Bus App differs from the current WiFi service on buses as the former is an integrated services system. It utilizes 4G mobile broadband and PaaS to create a network solution for buses, enabling operators to quickly develop new service-related business opportunities. Passengers can opt to use their verified Facebook or Google+ social media accounts or phone number to login. Subsequently, Y5Bus provides customized, real-time recommendations on restaurants, lodging, and entertainment, along with shopping guides, points of interest along the route, and coupons.
Dr. Chiueh commented that ITRI specially developed the Y5Bus App to meet the needs emerging from the popularity of smartphone usage and 4G communications. It worked with domestic bus companies on establishing a 4G WiFi environment, allowing passengers to be able to directly access cloud services and enjoy the various services offered by bus companies, thereby creating new business models in mobile commerce. To date, over 900 buses throughout Taiwan have been outfitted, and by the end of this year a total of 1200 buses will provide Y5Bus services.
Besides Y5Bus, ITRI’s demonstration at MWC 2017 included a multiple base station, multiple antenna system that mainly resolves the ultra-dense base station interference associated with 5G UDN. This technology concentrates the hyper-dense deployment of small cells into a single multi-antenna super base station. Meanwhile, the destructive interference between the base stations is converted into a constructive wave, ensuring users enjoy high quality mobile communication services and achieving network performance at a linear growth in the number of base stations. Features of this technology include:
- Employing a MAC/PHY split to implement the C-RAN architecture, with the use of nFAPI interface between the MAC and PHY layers, which also supports Network MIMO;
- Utilizing Joint Transmission technology in which each base station requires only two antennas;
- Adopting Channel Prediction technology to reduce the number of channel returns;
- Applying parallelized Precoding Matrix calculations to increase operation speed.
