What are PCS?

PC or personal communication service is a designation of part of the radiofrequency zone, which is devoted to the use of a wireless telephone service in the United States, Canada and Mexico. Here are several backgrounds about the development of the PC concept and how PC continues to work today.

Soon in the development of mobile phone technology, the need to assign specific bandwidths to signals that would be used for cellular services. To this end, a radio zone was studied for this purpose, which would be for exclusive use of cellular wireless networks. Finally, the conclusions of FCC in the United States and the Industry of Canada were that the designation of the MHz scope in 1850-1990 for use with a mobile phone service would ensure that there were no frequencies used for public broadcasting or government functions. During 1994, both countries created the 1900 MHz band as a standard for use in any wireless network based on service in the United States or Canada. This effectively created the first unified to conceiveAč on the market.

Although this has helped to ensure that the new technology does not interfere with other bandwidth use, and also help to facilitate the process of interaction with the wiring network, it did not solve the problem of interaction of mobile phones with European and Asian sites and services. Over time, the development of telephone phones will be allowed to process signals that would suit the North American standards and other global standards to be compatible. Sometimes it is referred to as GSM multi -band systems, many parts of the world now use PC as a term to describe GSM services that work in a number of MHz 1900.

In the United States, Sprint was the first service provider to establish a real PCS service and worked with a basic station to anchor the service Voblast DC Baltimore-Washington in the country. The station was actually configured to work with the GSM-1900 standards, which allowed to useservice with international calling. Over time, Sprint has upgraded to CDMA technology for its cellular network, which caused the base to be outdated, although it continued to provide signaling in the now defined range of PCS. Today, almost every cell provider in the continental United States operates in the range of PCS 1850-1900 MHz, allowing many current features of possible mobile phone functions because they relate to interaction with other wireless networks.
