Description: It is p resented in the paper that it is difficult to realize the sectored cell and the same antenna for
multip le frequency channels by analyzing the theory of the smart antenna. Therefore it can be p roved that the smart
antenna technology is not a commercial technology at p resent. Asymmetry slot distribution between inter2cells/ sec2
torswould bring the transmission and receiving interference between the inter2cells/ sectors, so it can’t be put into
p ractical app lication. The technological defects of the TD2SCDMA standard are analyzed in the paper from many as2
pects, such as the characteristics of 2 GHz frequency band,MS’s transmission power, a cell capacity on up link /
downlink and so on. TD2SCDMA system is difficult to support different radio access data rates, such as vehicular
environment: 144 kbit/ s, pedestrian environment: 384 kbit/ s, indoor office environment: 2. 048 Mbit/ s, which
are required by 3G standards
