60 GHz WLAN applications and implementation aspects

Abstract

Various wireless applications are currently under development for the unlicensed 60 GHz band. This paper describes three examples with different system requirements. The first two are point-to-multipoint wireless networks (in an airplane and in a car) and the third one is a short range point-to-point connection. Special requirements of the applications are a high number of users for the point-to-multipoint connection and a high data rate of 10 Gbit/s for the point-to-point connection system. Implementation aspects are pointed out, which are important to demonstrate the functionality of the system in a relevant environment and are key aspects to develop the related products. For example, integration aspects of the antenna into an airplane passenger seat and the receiver concept of the radio frequency-(RF) front-end to reducing the power consumption at ultrahigh data rates are described. Additionally, to determine the geometrical system architecture, ray-tracing simulations inside an aircraft and inside a car were performed.

Wideband 60 GHz SiGe-BiCMOS vector modulator for ultra-high-datarate wireless transmitters

“…The large market volume for diverse consumer applications [1] has also driven research interest in the monolithic intergration of the electronic circuitry required for the data transmission, because this enables a dramatic reduction of production costs. Among the various modulation schemes compatible with system-onship integration, a single carrier QPSK offers a good compromise between power and spectral efficiency: over 10 Gbps are possible over the full band, while still requiring relatively simple modulation and demodulation circuitry [1]. Among the several mm-wave circuit blocks necessary in a QPSK frontend, a vector quadrature modulator is a key component on the transmitter side.…”
