The correct answer is: Limited capacity.
2G standards are the second generation of cellular network technologies. They were developed in the early 1990s and introduced digital modulation, which allowed for higher data rates and better voice quality than previous analog systems. However, 2G standards have a limited capacity, which means that they can only support a certain number of users at a time. This can lead to congestion and dropped calls, especially in areas with a high population density.
Short Messaging Service (SMS) is a feature of 2G standards that allows users to send and receive text messages. It is a relatively low-bandwidth service, so it does not contribute significantly to the limited capacity of 2G networks.
Digital modulation is a technique used to encode digital data for transmission over a communication channel. It is a key feature of 2G standards, and it is not a disadvantage.
Limited Internet browsing is another feature of 2G standards. It is possible to browse the internet on a 2G network, but the data rates are slow and the experience is not very good. This is because 2G networks were not designed for high-speed data transmission.
In conclusion, the correct answer to the question “Which is one of the disadvantages of 2G standards?” is Limited capacity.
