Advantages of PCS over existing cellular systems


-- improvement of  equipment: the transceiving unit will be smaller in size,

utilizing lower power and hence lengthens battery life.


-- smaller antennas located discretely on buildings or telephone poles,

and so they blend very well with the environment.


-- PCS allows user to communicate through voice and data simulataneously.

However, there is not much information on data services provided by PCS.


-- the telephone number under PCS is permantly assigned to the user,

regardless of what his or her service provider is. That is, even if he or she

changes the service provider, the telephone number will not be changed.


Up to now, there are now two standards which dominate the mobile 

communications field: GSM and PCS. Technology suppliers will continue to 

maintain the most advanced research and development on improving these 

two standards.


New operators will rush to proivde services under these two standards all over

places in the world. With so much competition between the operators, the 

technology suppliers may be the true winners in this field but not the operators.
