As wireless infrastructure evolves to new standards such as 3G, HSDPA, WiMAX and 4G, two key requirements are emerging in the industry:
- The need for increased performance to support new standards, higher capacity, greater coverage, and new advanced features such as smart antennas;
- The desire to move to common, software-defined radio platforms which can be upgraded in the field as standards and features evolve;
|
Base stations must now handle greater capacity, process higher data rates and support several multimedia standards.
Operators require equipment that can be cost efficiently configured for multiple coverage/capacity scenarios and allow easy deployment of new services.
Equipment manufacturers need to improve return-on-investment and time-to-market by adopting software-defined radio platforms.
Aspex’s high-performance Linedancer family of devices enable base station manufacturers to deliver equipment which is:
 |
|
|
|
| |
Common hardware platform supporting multiple standards and configurations, as well as advanced techniques such as Adaptive Modulation and Coding (AMC), Space Time Coding (STC), Multiple Input, Multiple Output (MIMO), Multi-User Detection (MUD) and Beamforming
|
|
| |
Fully software programmable device avoid the need for costly on-site maintenance, downtime, or swap-outs when new features or services are introduced
|
|
| |
Each Linedancer chip contains more than 4,000 parallel processing elements and a powerful, linear interprocessor communication network which enables additional devices to be simply connected to “dial up” whatever processing power is needed to do the job.
|
Linedancer is ideally suited to the following base station tasks:
-
W-CDMA chip rate processing
-
Smart antenna processing (Beamforming, Space Time Coding & MIMO)
-
OFDM modulation & demodulation
-
PA linearisation
-
Software Defined Radio
