1.1
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
