PCS technology Vs Cell phone
With a mission to furnish a service that features crystal-clear connections, rectified and amended reliability and a hassle-free experience for customers, the PCS technology stands to change the way people use wireless communications. "Let's begin with the basics, and discuss what analog cellular is all about. In North America, we use a system known as AMPS. This system has its beginnings in 1975 when AT&T began to look into a replacement for their old mobile telephone system. The trouble with the earlier system was a distinct lack of capacity. Within a metropolitan area, only about 20 or 30 subscribers could use the system at any one time. Back in those days however, few people could afford a mobile phone, and those that had them didn't use them all that frequently." The FCC uses PCS (Personal Communication Services) to depict a newer class of wireless communications services currently authorized. PCS systems use a different radio frequency, the 1.9 GHz band, than cellular phones and commonly use all-digital technology for transmission and reception.
