GSM Vs CDMA What is the difference between GSM and CDMA? The comparison of GSM vs CDMA is very useful and interesting from buyer's as well as student's perspective. The following article on GSM vs CDMA will help you to understand the differences between these two technologies. GSM is an acronym for Groupe Special Mobile, which has now been changed to Global System for Mobile Communication. CDMA refers to Code Division Multiple Access. The working of GSM and CDMA is very different. But the end result, after the implementation of the two technologies, is highly similar and matching in many ways.

Every cell has a corresponding network tower, which serves the mobile phones in that cellular area. For example: Imagine a honeycomb on a tree in a hexagonal shaped garden. The garden has many flowers. The honeybees collect the nectar from the flowers, and deposit it in the honeycomb. Your mobile phones are like the flowers, the network tower is like honeycomb, and the bees are the signals. CDMA Explained As the name suggests (Code Division Multiple Access), there are many devices which use the same spread spectrum (hence multiple access). There is one physical channel, and a special code for every device in the coverage network. Using this code, the signal of the device is multiplexed,
