ASTRI Completes WiMAX Interoperability Testing with Base Stations

The Hong Kong Applied Science and Technology Research Institute reportedly announced that it has successfully completed interoperability testing of its WiMAX Access Service Network Gateway with Micro Base Station - from Institute for Information Industry in Taiwan.
 
ASTRI said that its ASN-GW offers end-to-end IP connectivity between WiMAX mobile subscriber and IP core service networks, helping mobile users enjoy various service applications, such as Web browsing, file transfer and media streaming.
 
The ASTRI ASN-GW is WiMAX Forum standard-complaint. It can be customized to support multiple vendors and multiple models 802.16e base stations, disregard of their interfaces (R6 or extended R6) and profiles (Profile A or C). With this, mobile operators can choose from different vendors BS and MS, in order to reduce deployment and operational costs. In addition, the mobile operators can also offer a complete Mobile WiMAX solution for the users, said ASTRI.
 
Featuring advanced radio resource management optimization for better coverage and capacity, the ASTRI ASN-GW has scaleable hardware that is cost-effective. This scalable hardware allows low entry cost networks with flexibility for capacity upgrade, said ASTRI.
 
The interoperability testing between ASTRI’s ASN-GW and III’s Base Station was based on the specifications laid down by the WiMAX Forum’s Network Working Group, which defines the WiMAX Network Architecture. The architecture is built on – ASN (Access Service Network) and CSN (Connectivity Service Network). The ASN incorporates base stations and ASN-gateway, with IP data path and R6 control path between them.
 
ASTRI said that the testing between ASTRI’s ASN-GW and III’s Base Station was done over open R6 interface. The completion of interoperability testing demonstrates the reliability of network entry, user authentication, network exit and re-entry, company officials say. It also validates the multi-vendor interoperability of the ASN-GW platform across different vendors’ base stations and MS solutions.

The Hong Kong Applied Science and Technology Research Institute was founded by the Government of Hong Kong Special Administrative Region in 2000 to improve technological advances for Hong Kong via applied research.
