personal communication network. [PCN]

The PCN system was first initiated by LORD YOUND in 1988. The characteristics of PCN are as follow.

v     Operating frequency 1.7 to 1.88 GHz ( 1710-1785 MHz and 1805-1880 MHz)

v     Uses 30 GHz or up for microwave back bone system.

v     Covers both small cells and large cells.

v     Coverage inside and outside buildings

v     Hand over

v     Call delivery

v     Portable hand set

v     User intelligent network

PCN uses the DCS – 1800 system. Which is similar to GSM but up converts the frequency to 1.7 to 1.88 GHz therefore the network structure the signal structure and the transmission characterize are similar between PCN and GSM but operation frequencies are different.
