What is cellular technology
The Chinese meaning of Cellular is "cellular (technology)", which is a wireless communication technology. This technology divides a geographical area into several cells, called "cells" (ie Cells). Cellular technology is so named. Mobile phones (or mobile phones) all use this technology, so they are often referred to as cellular phones. The purpose of dividing a large geographic area into multiple "cells" is to make full use of the limited wireless transmission frequency. Each group of connections (for wireless telephones, each group of sessions) requires a dedicated frequency, and there are only about 1,000 available frequencies. In order to allow more conversations to proceed simultaneously, the cellular system allocates a certain amount of frequency to each "cell" (ie, each small area). Different cells can use the same frequency, so that limited wireless resources can be fully utilized. Common cellular systems include GSM and CDMA, which are all second-generation communication technologies.
