WinMax

The WinMax family is the first generation of Wintegra solution for the WiMAX market.  From a silicon technology perspective, WinMax is based on the WinPath2 family architecture.   It implements the MAC and the transport functions, and interfaces to customer-provided external base band processors such as DSPs.

Associated with the WinMax family and licensed separately is a special software package that implements the lower WiMax 802.16 MAC in data path software running on the WinMax chip, and implements the upper WiMax 802.16 MAC in C-code running on the on-chip MIPS processor in that same WinMax chip.   In addition software tools are offered that allow customers to easily and quickly customize the MAC scheduling functions for the particular market requirements of the base stations.

WinMax has found many homes in WiMAX base stations.   It can be used in one of three ways:

  • Handling just the transport functions of the Network Interface Card (NIC), which may also referred to as the transport card for the entire WiMax base station.
  • Handling just the base band MAC function, aggregating and scheduling traffic between the backplane and the base band DSPs for up to three sectors on a single radio access card.
  • Handling both transport and MAC functions in the same WinMax chip in a smaller pico base station, usually just a single sector.

WinMax offers configurations from 2 to 6 on-chip data path engines and includes an on-chip MIPS microprocessor.
