  3. Another trend is towards phones that double as both fixed and mobile devices, using cellular networks when outdoors and switching to fixed networks, accessed via a short - range radio link to a small basestation, when indoors

    另一個趨勢是電話會兼作移動設備與固定設備，在室外使用蜂窩式網路，而進入室內時，可通過短程電波接入小型基站切換至固話網路。
  4. Wireless position location has received considerable attention over the past few years due to the united states federal communications commission ' s ( fcc ) 1996 report and order. the fcc mandate requires that all wireless service providers, including cellular, personal communications services ( pcs ), and some special mobile radio ( smr ) licensees, provide location information for enhanced - 911 ( e - 911 ) safety services

    隨著美聯邦通信委員會於1996年提出要求各種無線蜂窩網對發出e - 911緊急呼叫的移動臺提供滿足一定精度要求的定位服務以來，無線蜂窩定位技術一直引起廣泛的關注。
  5. Gprs 900 1800mhz tdma digital cellular mobile communication network gprs general packet radio service test methods of tunnelling protocol

  7. In cellular envirorunents, because of the influence of several adverse factors, such as muitipath, non - line - of sight propagation, noise, interference and channel frequency characteristics, radio statistics measuremenis like tdoa, toa and aoa related to mobile position, the performance of location algorithms mny be significantly degraded and the position estimation of ms is inevitably biased

    在蜂窩網路環境中，由於受多徑、非視距傳播、噪聲、干擾和通道頻率特性等多種不利因素的綜合影響，使tdoa 、 toa 、 aoa等與移動臺位置有關的電波特徵測量值不可避免地出現較大誤差，從而使各種定位演算法的性能顯著下降，造成移動臺位置估計出現較大偏差。
