This project is one of the projects in ASTRI’s Thrust #1 “Open Broadband Wireless Network and Applications”. The objectives of this project is to develop an Open Broadband Wireless Innovation Platform (WIP) through integration of ASTRI and 3rd party’s technologies and products for the purposes of 1) providing a (configurable) network environment for system development, integration and verification in Thrust #1 for commercialization; 2) acting as a test-bed for interoperability testing (IOT) and application trials; and 3) incubating design innovations of ASTRI’s Thrust #1 and other projects such as Software-Defined Networking (SDN), Network Functions Virtualization (NFV), Cloud Computing, and Machine Type Communications (MTC), etc. The deliverables of this project include (1) deployment of an LTE small cell network in both indoor and outdoor environment with Self-Organizing Network (SON) capability, (2) deployment of WiFi APs and a WiFi/LTE Convergence Gateway with a policy based traffic offloading function, (3) Active Antenna System (AAS) beam forming configuration and testing , and (4) LTE IOT tool to assist IOT and system integration of application trials on WIP. ASTRI has developed LTE technologies in various areas such as baseband, RF system, and core network software, and become one of the leaders in providing LTE technologies. This project will leverage ASTRI's core competence in LTE to provide an end-to-end broadband wireless network platform. The WIP will enable cross teams/domains collaboration within ASTRI to create competitive edges for developing more innovative products and engaging more and extended industry collaborations, from design houses, silicon suppliers and equipment manufacturers to system integrators and operators. The WIP will also help to upgrade/advance the technical capability and competiveness of the communications industry in Hong Kong and the region.
