Once accustomed to unteathered opera- tion, users resent being tied to a desk or a fixed location, but will endure it when there is some substantial benefit, such as higher resolution or bandwidth. Recent technolog- ical advances, however, such as the scaling of VLSI, the development of low-power circuit design techniques and architectures, increasing battery energy capacity, and advanced displays, are rapidly improving the capabilities of wireless devices. Many of the technological advances contributing to this revolution pertain to the wireless medium itself. There are two viable media: radio and optical. In radio, spread-spectrum techniques allow different users and services to coexist in the same bandwidth, and new microwave frequencies with plentiful bandwidth become viable as the speed of the supporting low-cost electronics increases. Radio has the advantage of being available ubiquitously indoors and outdoors, with the possibility of a seam- less system infrastructure that allows users to move between the two. There are unan- swered (but likely to be beni | | 出版日期 | Book 1994 | | 關(guān)鍵詞 | Counter; Modulation; Potential; communication; electronics; modeling; optics; information and communication | | 版次 | 1 | | doi | https://doi.org/10.1007/978-1-4615-2700-8 | | isbn_softcover | 978-1-4613-6162-6 | | isbn_ebook | 978-1-4615-2700-8Series ISSN 0893-3405 | | issn_series | 0893-3405 | | copyright | Springer Science+Business Media New York 1994 |
