In this article, we will explore what network Verizon operates on, the differences between GSM and CDMA, and how this impacts users.
The Basics of Cellular Networks
Before delving into whether Verizon is GSM or CDMA, it is essential to understand what these two technologies entail. GSM (Global System for Mobile Communications) and CDMA (Code Division Multiple Access) are two different standards used by mobile phone networks around the world.
What is GSM?
GSM, developed in Europe in the early 1990s, is a standard designed for mobile communications. Some of the key features of GSM include:
- SIM Cards: GSM networks use SIM cards (Subscriber Identity Modules) to store user information, contacts, and other data. This allows for easy switching between devices.
- Frequency Bands: GSM operates on specific frequency bands, typically 850 MHz, 900 MHz, 1800 MHz, and 1900 MHz, which vary by country.
GSM networks also support a range of services, including voice calls, SMS messaging, and mobile data.
What is CDMA?
CDMA, primarily used in the United States, was developed by Qualcomm in the 1990s. It employs a different method of encoding and decoding signals, allowing multiple calls to occupy the same channel simultaneously. Key characteristics of CDMA include:
- No SIM Card Requirement: Unlike GSM, CDMA networks do not officially use SIM cards, though many newer devices include them for compatibility.
- Network Access: Devices are “locked” to a specific carrier, meaning you cannot easily switch phones between carriers without unlocking them first.
CDMA is designed for enhanced security and greater capacity, handling more simultaneous calls without needing additional bandwidth.
