摘要：

Some of the views on the fundamental physical relationships between wireless system transmission rate (bit rate) and transmission range and on the effects of some other system parameters on these relationships,are discussed. The relationship between range and transmission rate depends on several factors, such as frequency range and interference either from other users in the same system or from transmissions from other wireless systems. Sometimes the range and transmission rate for different systems have uncertainty in their values because of these factors. The effect of these factors will further reduce the data transmission rate below the fundamental limit due to signal-to-noise ratio (SNR). Higher-level modulations, such as 1--level quadrature amplitude modulation (16-QAM) and 64-QAM, allows higher transmission bit rates within a given bandwidth.
