Network Wireless Systems Require New Test Equipment Architecture

摘要

The latest designs being proposed in the network wireless communications industry are making use of digital IF-based architectures. Modern test equipment must also migrate to this architecture to maintain correlation in simulation testing. As the designers and builders of network wireless communications systems look to cover the demand for enhanced performance of the base station, a myriad of innovative techniques are being implemented. One hybrid solution is through software-defined code formats that optimize bandwidth utilization in the allocated frequency that is resident in the base station radio. This move toward the software-defined radio for third-generation (3G) wireless products has taxed the capabilities of today's test methods.
