Texas Instruments today announced a pico base station solution that combines a high performance DSP, optimized baseband software and development tools. Pico base stations are small, low-power cellular network nodes that extend the reach of 3G wireless networks to improve consumers' coverage and access to high-speed data. TI's newest wireless infrastructure solution offers flexibility, differentiation and faster time-to-market to base station manufacturers and service providers rolling out advanced wireless networking equipment.
By using the industry's highest-performance DSP, TI's 1 GHz TMS320TCI6482, and optimized W-CDMA software libraries, infrastructure OEMs can design a compact baseband solution, thereby dramatically reducing the overall cost of a pico base station solution. For example, a pico base station supporting 32 simultaneous users can be implemented with just two TCI6482 DSPs, compared to previous solutions that were more complex. These small base stations can be deployed in environments such as college campuses, subways, airports and office buildings. OEMs can realize a high channel density solution with TI's 1 GHz DSP because it can efficiently support the complex needs of W-CDMA baseband processing including symbol rate, chip rate and parts of the medium access control (MAC) layer functionality.
The TCI6482 DSP also supports the high speed downlink packet access (HSDPA) and high speed uplink packet access (HSUPA) channels that are defined as part of Release 6 of the 3GPP W-CDMA standard. Additionally, smaller femto base station solutions used in personal area networks can be supported on a single DSP to boost 3G network access for individuals and small teams.
TI's TCI6482 DSP supports high performance baseband solutions at a relatively low power of just three watts. Low power is a key metric for this application because small form factor base stations typically do not have fan cooling capabilities found in full size or macro base stations.
Using a software programmable approach enables OEMs to develop the most flexible baseband solution. TI's software offering includes highly optimized software libraries that form the building blocks of a W-CDMA baseband solution.
Software upgrades in the field to support new features protect operator's investments, thereby reducing their exposure to the risks involved in emerging applications.
By using TI's software to develop their baseband solution, OEMs can lower development time and cost, reducing time to market.
TI's new pico base station technology includes the TCI6482 DSP and highly optimized symbol rate and chip rate software libraries. It will be available later this year.
