Meeting mobile WiMAX performance requirements
Feb 1, 2007 12:00 PM  By David Patterson and Lars Johnsson

This article discusses a new-generation chipset that is designed to meet the performance demands a mobile WiMAX handsets and laptops. The chipset includes a baseband chip that minimizes processing load on the host processor and a direct-conversion radio, which supports 2 GHz and 3 GHz designs, as well as programmable channel bandwidths from 5 MHz to 10 MHz. A complete mobile WiMAX reference design kit is described.

Test for success

Mobile WiMAX is a major, long-term opportunity for device makers. But to capitalize on that opportunity, manufacturers of smartphones, PDAs and other handheld devices need to pay attention to how chipset suppliers implement Wave 2. To enable users to fully assess a chipset's Wave 2 capabilities, the BCS200 comes with a reference design kit, including host driver software and RF calibration tools. This kit enables device makers to quickly produce mobile WiMAX products. The reference design kit for mobile WiMAX Wave 2 modem includes:

  • reference schematic and layout for the chipset implementation;

  • Modem prototypes for software integration and development;

  • chipset samples for building prototypes;

  • bill of materials for the entire modem;

  • all firmware that runs on the active components;

  • host driver software for integration into the host device;

  • application programming interfaces (APIs) with extensive documentation; and

  • test scripts and recommended test tools (third-party equipment).

This reference design kit contains the recipe to build and integrate a mobile WiMAX modem into any device. It enables makers of wireless equipment to expand into the mobile WiMAX space as well as allow consumer electronics companies to consider including mobile WiMAX functionality in their devices, without requiring them to be wireless design experts.
