Introduction

1.1

The LP1070 Family

Freescale Semiconductor’s 802.11 LP1070 family

consists of high-performance, highly optimized PHY

and MAC baseband Wireless LAN processors that fully

implement the IEEE 802.11a, 802.11b and 802.11g PHY

standards. These baseband processors are poised to

revolutionize the Wireless LAN industry by setting new

standards for power consumption, size, cost and

performance.

The LP1070 family is based on Freescale's proprietary

Wireless Broadband Signal Processor™ (WBSP™), an

innovative and revolutionary receiver architecture that

significantly reduces size and power consumption while

providing maximum flexibility to support multiple

wireless standards with no additional overhead.

In addition to their superior performance and ultra low

power consumption, the LP1070 processors provide the

customers with the flexibility to tailor the chip

characteristics to their needs. With software control, the
