  • In the nineteenth century, scientists, mathematician, engineers and innovators started investigating electromagnetism. The theory that underpins wireless communications was formed by Maxwell. Early demonstrations took place by Hertz, Tesla and others. Marconi demonstrated the first wireless transmission. Since then, the range of applications has expanded at an immense rate, together with the underpinning technology. The rate of development has been incredible and today the level of technical and commercial maturity is very high.

  • Over many years, RF-MEMS have been a hot topic in research at the technology and device level. In particular, various kinds of mechanical Si-MEMS resonators and piezoelectric BAW (bulk acoustic wave) resonators have been developed. The BAW technology has made its way to commercial products for passive RF filters, in particular for duplexers in RF transceiver front ends for cellular communications. Beyond their use in filters, micromachined resonators can also be used in conjunction with active devices in innovative circuits and architectures.

  • ADC's GSM Network-In-A-Box (NIB) combines GSM MSC, Base Station Controller and Base Transceiver Station in a single box. It provides the smallest and lowest entry point into the GSM wireless space. ADC's MSC, BSC and BTS work hand-in-hand to reduce the total cost of network ownership, providing a network growth path for existing and future customers. ADC's GSM products provide a compact and cost-effective platform, which help lower the cost of network ownership.
