As the virtues of flexible wireless anywhere computing begin to be understood-there is a growing interest in wireless local area networking (LAN) technologies. Unlike their wide area cellular or PCS-based counterparts, wireless LAN offers significantly higher speeds and the cost-effectiveness of low power transmission in the unlicensed spectrum. This paper surveys existing wireless LAN technologies and their projected market impact on the corporate and home environments. Variants of the 802.11 specification and the evolution to the 802.11b, capable of 11 Mbps, are described. It touches on some of today's practical issues surrounding large-scale wireless LAN campus deployments and focuses primarily on HiperLAN/2, which support automatic frequency allocation, QoS/connection-orientation and is capable of physical layer rates of up to 54 Mbps. The architecture and structure of HiperLAN/2 are described along with the current standardization status. Additionally, the paper also touches on wireless LAN spectrum, chip set implementation and interoperability issues. Contrasts to wireless wide area and personal area networking (e.g. Bluetooth) technologies are also given.","PeriodicalId":291027,"journal":{"name":"2000 IEEE Emerging Technologies Symposium on Broadband, Wireless Internet Access.

Global standardization efforts of BWA systems based on cable modem 基于电缆调制解调器的BWA系统的全球标准化工作

Nortel Networks has been spearheading the BWA standards efforts in ITU-R, ITU-T and in IEEE 802.16, that uses the cable modem specifications as a basis for wireless access systems in order to achieve economies of scale. The cable modem technical parameters for physical and media access control layers have been adapted to the wireless environment to support a bidirectional wireless access system for interactive services. This paper presents the BWA (broadband wireless acceas) physical and media access control (MAC) standardization efforts that are in progress in IEEE 802.16 in the 10-40 GHz band, with a focus on the LMDS (local multipoint distribution service) band in the U.S. Nortel Networks is leading the effort to standardize the DOCSIS based parameters for PHY/MAC standardization in IEEE 802.16. The services that will be supported by BWA systems include fast Internet access (supporting both IP and ATM traffic), video and interactive television. The key features of this BWA system are multiple quality of service (QoS) support, dynamic service management, support of real-time services along with cryptographic authentication of the users for protection against theft of service.","PeriodicalId":291027,"journal":{"name":"2000 IEEE Emerging Technologies Symposium on Broadband, Wireless Internet Access.

Microwave A/D and D/A converters enable digital RF systems where virtually all information is processed or generated by direct digital means. A complete receiver link can consist of a sensor (e.g. antenna or photodetector), an N-bit A/D converter, and a digital signal processor. A complete transmitter can be built using the appropriate actuator (antenna or laser), an N-bit D/A converter and a digital waveform synthesizer. Future radar, electronic warfare, and communication systems will exploit this all-digital approach to increase the performance and flexibility while lowering the cost. We describe how quantum switching devices can be used to build A/D converters with ultimate sampling rates well above 100 GHz. Resonant tunneling diodes (RTDs) are integrated with heterojunction field effect or bipolar transistors to sample, quantize, encode, demodulate, and filter broadband analog signals. Single-ended and differential circuits are discussed and compared for power consumption, area, and speed. Comparisons are made between RTD/FET and FET-only A/D functions. Results are shown for A/D quantizers that have sub-millivolt threshold sensitivity at 10 GHz sampling rates.","PeriodicalId":291027,"journal":{"name":"2000 IEEE Emerging Technologies Symposium on Broadband, Wireless Internet Access.
