  • Abstract LMDS is the most obtrusive among mini-meter wave propagation techniques. Because it can provide wideband integrated services including two-way voice, video, and data transmission. The asymmetry between downstream and upstream is quite consistent with the normal data flow, particularly for residential applications. Of course the spectrum can also be used to provide symmetric traffic that would typically be required for business applications.
      In chapter 2, we use cells planning, which suffers less inter-cell interference in comparison with the typical cell planning. Chapter 3 analyzes the technique of CDMA with power control scheme can reduce inter-cell interference effectively in clear air. Besides, high rainfall attenuation is a significant challenges associated with deploying systems at Ka band. Chapter 4 studies the Dynamic modulation scheme effect in LMDS, we can increase the system data rate by using higher modulation level of data modulation in certain parts had better channel quality of a sector. Finally, chapter 5 gives the conclusions.
