What is the data speed range for 2G cellular technology?

The data speed range for 2G cellular technology primarily lies between 14.4 Kbps and 64 Kbps. This range is significant because 2G was the first digital cellular technology, representing a shift from analog systems. The introduction of digital transmission enabled more efficient use of the radio spectrum and allowed for services such as SMS and basic data services.

The lower end of the range (14.4 Kbps) reflects the speeds provided by earlier 2G technologies like GSM, while the higher end (64 Kbps) is representative of later enhancements like GPRS (General Packet Radio Services), which facilitated better data communication. This speed is considerably slower than what is found in subsequent generations of technology, such as 3G, 4G, and 5G, making 2G primarily suitable for simple text messaging and low-bandwidth applications.

Other ranges mentioned in the options refer to different technologies: the range associated with 30 KHz and 2 Kbps is not relevant to 2G standards, while 1-2 Mbps and 50-100 Mbps represent the data speeds found in much more advanced technologies like 3G and 4G respectively.
