Voltage-controlled surface acoustic wave (SAW) oscillators (VCSO) have been used for many years in both commercial and military applications. The low phase noise allows frequency multiplication to higher frequencies for use as sources, such as local oscillators in radar and other microwave systems. The excellent tuning linearity provides outstanding...

In part I, the economic case from the network operator’s perspective was reviewed and it was found that as operators improve their residual BER performance, their market space is expanded from simple voice applications to e-commerce transactions and other data traffic which demands ultra low error rates. Next, the...

Wireless local area networks (WLAN) are becoming increasingly popular in the corporate environment. They provide high speed connectivity and easy access to corporate networks without requiring wiring. Flexibility is key with WLAN capability. In a corporate environment, individuals can be mobile and at the same time constantly be connected...
