There are pros and cons to both technologies. GSM is widely used in developing countries, while CDMA has limited coverage. GSM makes roaming easier, but has a reputation for being less secure. Security algorithms in CDMA are susceptible to cyberattacks, and GSM lags behind newer connectivity standards like 4G LTE. Both technologies require a great deal of anonig processing power to transmit data. Ultimately, the choice comes down to how you plan to use them.
One major difference between the two technologies is range. Despite the wide range of 2G coverage, GSM remains popular in IoT applications. GSM uses low-power wide area networks to provide long-range cellular communications. In addition, GSM is more energy-efficient, which is ideal for battery-powered devices. Despite this, many countries are sunsetting their 2G networks. Therefore, the two technologies may compete against each other.
Range and bandwidth are closely tied. The farther the device is from the network, the higher its range and bandwidth. However, if you need real-time tracking, cheap high-latency technology will not suffice. On the other hand, a lower-latency solution might be necessary if you’re looking for real-time tracking. Both options have advantages and disadvantages, so choose the right one.
NB-IoT is designed for IoT deployments. It has better indoor penetration and low power consumption. But it’s not as widespread as GSM. Unlike LTE-M, GSM has tinyzonetv a higher bandwidth ceiling and a lower power requirement. NB-IoT is not available in many countries, but it’s expected to come out in the U.S. by 2019
