The LP1070 family is based on Freescale's proprietary
Wireless Broadband Signal ProcessorTM (WBSPTM), 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
