Texas Instruments is targeting femtocell designs with a family
of DSPs which includes the TMS320TCI6485 dual 850MHz C64x+ core
device.
TI sees
two separate markets, one for lower cost home femtocell
basestations and the other enterprise market for higher performance
femtocells.
As a result there is a three core chip, the TMS320TCI6489 which is
capable of delivering 2.55GHz performance for what TI called “super
femto” applications.
The difference between a standard femtocell and super femtocell is
that the former will support up to eight residential users while
the later will support as many as 32 users in a business
environment.
The DSPs support Linux and are compatible with HSPA mobile
networks. They will be used with 2G/3G and 4G systems including
GSM, CDMA, WCDMA, TD-SCDMA, WiMAX and LTE.
Using the software reference design available from Continuous
Computing and mimoOn, which is designed to provide software for
Layer 1, 2 and 3 wireless protocol processing, femtocells will
support video streaming, interactive gaming, music sharing and
other bandwidth-intense multimedia tasks.
TI has also teamed with Continuous Computing, a protocol software
specialist, and German software-defined radio firm mimoOn to
offer complete HSPA and LTE enterprise and residential
femtocells.
