Indonesia scientist has succesfully developed WiMAX chipset called XIRKA System on chip. Be thought out by Adiono Trio, scientist of Bandung Technology Institute (ITB), the chipset is design to compatible with WiMAX technology or broadband wireless access. This chipset can be applied both in fixed and mobile WiMAX. WiMAX can be choice the communication network to the next time.Asia Pacific Competitive Event, XIRKA successfull reach Asia Pacific Information Communication Technology Award (APICTA) on 2008 December with set aside participant the global industry from various country. At be a success Xirka processor, now Indonesia an one of country in "WiMAX Chipsets Producer Country Club" so far stand up US, France, Canada, Korea, and Japan.
XIRKA processor uniqueness is the ability to accommodate special requests for customization in order to create the best solution for our clients. This will enable any WiMAX equipment integrator and solution providers the ability to implement their own design and products for subscriber station (SS), mobile station (MS) and USB peripherals (including dongle and minicards).
Specifications:
