What is CDMA?
Code Division Multiple Access (CDMA) is a technology that allows our phones and various other devices to connect with cellular networks. CDMA allows devices to use the same frequency bands at the same time without interfering with each other.
Code Division Multiple Access
CDMA uses unique codes for each piece of data, which enables it to spread data across entire frequency bands, unlike other technologies which provide each device its separate channel.
It allows devices to efficiently use the available bandwidth, which means, even if there are multiple devices on the same network, there will not be any slowness in the network because of traffic. CDMA is a digital technology, it converts the data into signals, and then transmit it over the network, allowing to achieve better call quality compared to analog technology. Different types of CDMA are CDMA2000 1x, CDMA2000 1xEV-DO, and CDMA2000 1xEV-DV. They give better stuff like data and voice.
CDMA Working
CDMA uses spread spectrum technology, which assigns a unique code to encode the data of each user. This approach allows multiple users to exchange data simultaneously within the same frequency bands. The base station, also known as Node B, manages user communication by assigning specific codes to individual signals, which are then decoded by the intended recipients.
Difference Between UMTS and CDMA
In today’s world of communication, two primary technologies have had an important influence Which are Universal Mobile Telecommunications System(UMTS) and Code Division Multiple Access(CDMA).
Both have left a major impact on the path of mobile communication, providing enhanced call clarity, easier data transfer, and better coverage. It is important to understand the difference between these two.
