Choose the right architecture for mobile WiMAX

Posted: 02 Jul 2007 ?? ?Print Version ?Bookmark and Share

Keywords:mobile WiMAX systems? RF architecture? 802.16 standard?

WiMAX continues to grow in popularity, and the solidification of the 802.16 standard has ensured that the technology will be around for the long haul. As the fixed 802.16d standard becomes more readily available, the industry's focus turns to the mobile aspect of WiMAX in the 802.16e standard.

The focus is initially on customer premises equipment (CPE) where high-volume distribution is the business model. WiMAX base transceiver station (BTS) solutions are following closely to complete the system. The BTS is a lower-volume (and higher-cost) system where the RF architecture's performance generally takes precedence over cost.

Certainly, there is not an absolute right architecture for these WiMAX systems. Each option has advantages and disadvantages that the designer must weigh against the system's goal.

Russell Hoppenstein, RF applications engineer at Texas Instruments Inc., discusses more about choosing the suitable architecture for WiMAX systems.
