GSM and LTE are both cellular network technologies, but they represent different generations:

  • GSM (Global System for Mobile Communications): This is an older technology, considered second-generation (2G) and third-generation (3G). It supports both voice calls and data, but data speeds are much slower compared to LTE. GSM uses a combination of Frequency Division Multiple Access (FDMA) and Time Division Multiple Access (TDMA) to manage multiple users on the network.

  • LTE (Long Term Evolution): This is a newer, fourth-generation (4G) technology designed for high-speed data communication. LTE offers significantly faster data speeds than GSM, making it ideal for activities like streaming video, downloading large files, and real-time gaming. LTE uses a different access method to manage users on the network, resulting in more efficient data transfer.

In terms of modems:

  • GSM modems are no longer very common as most cellular networks are phasing out 2G and 3G support.
  • LTE modems are widely used in devices like cell phones, tablets, and mobile hotspots to connect to 4G networks for high-speed internet access.

Overall, if you're looking for a modem for internet access, an LTE modem is the clear choice due to its superior speed and wider availability.
